wow...:D show us some temps as soon as you can ;)
So the exhaust is pointing to the pci-e Slot? mhh

that being said, i cant wait for ur review dnottis!
The XL doesnt put out nearly the heat of an X1800XT, especially when the X1800XT is overclocked. I have it installed and am gathering results.Quote:

maybe someone should tell them about the thermalright v-1Quote:

interesting to see your results dnottis
try undervolting the X1800XT mem i was pleasantly surprised it clocked much higher
SIOUX said to under to 2.034v which helped him and i tried it with stock heatsink on my HIS X1800XT didn't do much
then i went water and tried lower at 1.985v mem and went from 936 to 963mhz artifact free and 972-981 with slight artifact in GT3 in 3d2k05 - before any higher than 936 would lock up 3dmarks heh
I just received an email from my marketing contact at AC. They shipped the coolers with washers attached - this was a mistake and they need to be removed. This spacing is most likely causing contact issues with the core and memory.
You can see them here...

http://www.3dxtreme.net/other/ontap/...2/IMG_2647.jpg
I'll have to re-attach and try it later.
:slapass:
Funny - the other sites that already posted reviews would have just gotten this info as well....
isnt stock 1.8 for the mem? thats what it says in the overclocking tool...do i have to manually set it to 2.0ish volts?
interesting about the washers...
Mine did the same thing! I was clocking my mem @ 880 with ~1.97volts (both buffers and mem).Quote:

hell a xp120 is dead light, make a slightly smaller one with a diff base that can attach to a core and you will get amazing cooling. cathar proved it with watercooling, same principles apply PRESSURE, air being pushed at proper speeds and pressure downward onto fins/base cools much better than air simply being lighly pushed with little pressure/speed along fins won't ever cool aswell. hell even for people that have pci cards there is often a lot of space down past the pci cards close to the side panel area. you could have a xp120 style sink with the heatpipes sticking straight out towards side panel then turning down at 90 degrees with all the fins and the fan out the way. just getting bored of the same design being recycled over and over with no improvement whatsoever and with a design so limited in its cooling capability its a joke.
anyway, like i said gonna keep mentioning it in threads till someone somewhere notices.
I've said before that if I ever get some money(college sucks like that :(), I WILL find a way to mount a Big Typhoon on a VGA.
B/c if thats not Xtreme, what is?

At stock PE speeds I need the fan at 70% just to keep temps in the high 70's. I would love to cut the noise by a 1/3 of the stock and still maintain same temps if not lower. If I could stay mid 60's with no noise and slightly higher than PE speeds I would be quite happy indeed as this stock cooler is just too much for me. Too bad we have to wait till the end of February to see these but I also like how it is compatible with the newer cards coming from ATI later this month. Perhaps they will do some last minute changes in the next 6 weeks before dispatch that may make these coolers even better. I look extremely forward to your review Dnottis as I trust what you have to say.

i have no idea why they haven't noticed that, well, most people i know use onboard sound, lots of people have so much space and how hard is it to take an exsisting cpu sink design and just adjust base to have mounting slots for gfx cards.
you don't have to make some huge block that covers mem as all the sinks i've seen do it are so inaccurate spacing wise that you use so much paste(on the arctic coolers i've used in the past) to make contact you are just insulating the memory. oh, and not to mention thats the reason it takes SO long to get new compatible arctic coolers out(cos they just have to cover the memory ¬_¬ ) that the next freaking gen is out this time before the arctic cooler is available, if you don't cover the memory then old mounting would probably work. hence the zalman gpu sink fitting almost every card out no problem at all.
We want a highend monster cooler for our X1800XTPE cards now!
Totally agree Drunken master. 10CFM of air is pathetic.
Lets see some results Dnottis!:)
i wouldnt mount anything heavier than my SK7+ on a vga card. 485g plus figure 75g for your average 80mm fan. It does work quite well tho;) i use a 80mm tt SF2
Why can't AC just release a more aggressively fanned cooler already ('a la Zalman Fatal1ty products)?
I wouldn't mind an "Arctic Loudener" so long as it had a quiet mode, even if the quiet mode performed less admirably than the equally-loud mode on the Silencer.
This Accelero is no different--why not go balls out with the fan?
Here is an update....
After installing the Accelero I was seeing temperatures loading upwards of 85 - 90 deg c. Last evening I got the email from Arctic Cooling to remove the washers so I installed the Accelero last night for the second time. Load temps again crept upwards of 80 deg c. The zalman never broke 70 c, 68 has been the highest I ever saw using it. My chipset on the DFI Ultra-D usually idled at 32, loaded 39 maybe 40. With the Accelero running idle was 40 and load was 50+ as it dumped hot air on the motherboard and chipset area. I also found that once the Accelero got hot after loading for awhile, idle was always in the mid to high 50's. Basically the Accelero couldn't get out of it's own way - I feel that as the hot air was dumped onto the motherboard is was then re-circulated by the DFI chipset fan and sucked back in as intake. Moving hotter air through the cooler constantly. The design is poor, one of the plastic clips broke as I tried to open it for the review. Why wouldn't they use their traditional layout with hot air being exhausted out the rear of the Case. I checked contact multiple times and it was perfect everytime. You could even see the information on the core of the GPU mirrored in the TIM when I pulled it apart. Oh yea and since the fan was also silent at 100% - why not let the user connect to a 3 pin or 4 pin molex? Why go through the bother of powering from the onboard header and have to use a software app to override the speed??? Argh!
At the end of the night last night (about 4:15am) I removed the unit only to have the thermal pads stick and tear. So now the Accelero is a useless pile on my desk and in the process it ruined the X1800XT I had. Installation was a breeze, the Cooler was dead silent - however the performance was lousy to say the least. Not only that it killed an X1800XT in the process and drove chipset temps on a DFI Ultra-D way up.
Do you really want to try an Accelero? :nono:
I have voiced my complaints to Arctic Cooling already. I'm frustrated and now a bit pissed. I was the person that pointed out the wiring harness error on the NV5 Silencer Rev. 3 and saved them having to recall millions of units - instead only a few thousand were affected. How can the wiring harness be incorrect if the unit was installed on a card and tested? Ya really got me and when I phoned them and asked they sidestepped the question completely! The Accelero seems to be another step into the "what the hell were we thinking" area for Arctic Cooling. Arctic Cooling has never let me down, the last 2 out of three products have been less than well thought our products imo *NV5 rev 3 (how do you screw up the wiring harness, then include thermal tape that is dried up and not sticky?), Accelero (= dead X1800XT, soaring temps and hot chipset), the Freezer 64 Pro was great*
I dont forsee the review being completed after this mess I could care less to post any findings on the product at this point. Figured I'd deliver the news here - buyer beware with this one folks!
Really a bad news :(
Manufacturers must think about making some really cooler not amazing heatsink without fan....
Ouch...that's all I've gotta say. :(
man that really sucks. :(
So exactly how did it kill the 1800XT? Did it just overheat and die on you? I read through the post, but must have missed the cause of what killed it.
Oh dear.
It was more than likely the initial installation and lack of contact that caused high heat that killed it. AC told him to remove the washers AFTER he had already installed and tested it and found the temps to be horrendous. I can agree with him, I have had the NV5 Silencer for a 6800GT and ATI Silencer for an X850XT and both were great products that performed as advertised. The last 2 VGA coolers that Dean has had have really turned me off of their products. This one just by looking at it you can tell it's a poor design. Why in the world would you vent the exhaust down on the motherboard? What would make a bunch of engineers think that's a good idea?? Both Dean and I have cases with the same layout, the silverstone TJ06 and his is Enermax same chassis, with the reverse mounting of the motherboard, at least the venting of hot air from the Accelero would go up and away from the video card, but other cases that have the motherboard in it's usual orientation would just blow hot air under the video card, and since we know that hot air rises, it would just return to the Accelero fan and back through the cooler. Not a wise design IMO.Quote:

I've got my Accelero X1 yesterday morning... got the email yesterday afternoon about the washers... but i havn't got my 7800GT yet... so i havn't mounted it up
the cooler does look great, and is silent... but man... the base of the heatsink is sooo thin... i dont know if i want to mount it up on a brand new 7800... it looks more like a fancy stock cooler than an AC cooler...
and as everybody else... i love my Freezer 64 Pro...
same questions really... why exhaust on the PCI slots... why not provide more fins (look close to the fan)
only 3/4 of my core is covered by fins...
sorry guys, but I don't understand what is "washers"(look my sign :( )
what is it?
Not that I doubt Dnottis but I am a bit sceptical on the X1800XT actually being dead. I don't see how this can happen as my card runs mid 80's all the time and yes I have seen it into the 90's and without issue. I can't see the card just dying unless it was from something else but whatever. Very weird how your results are drastically off from others. I am going to wait and see what is said at a later time from a few other reviewers and general users as I am sure the unit must perform better than you are stating. I cannot see them letting it out the door performing the way it did when others are donig fine. Thanks for the review, I hope you don't take this offencively as I mean no harm just a bit surprised by your results.

Run your CPU without a cooler and load it - and I think you can understand what Im talking about. I'm not talking about a little bit of flashing. The whole screens just corrupts then the PC locks up. Its more than just the temps, there must not have been adequate contact.
About your comments about them letting it out the door.
Please read our review of the NV5 Silencer rev 3, or at least this page. (http://www.3dxtreme.net/index.php?id=acnvsilencer5rev35)
they shipped the cooler out the door with the wiring harness screwed up... now do you still believe AC wouldnt do this??

damn, i was waiting for a cooler from ac and now this.. ah crap, going to get a vf700-cu..
Again Dnottis im sorry. I feel real bad about your card as I know I would be physically sick to my stomach if my card starting doing that. I guess I have been very lucky as my card has hit into the 90'c range a few times yet I have no issues. My card is always late 70's to early 80's no matter what so I am used to seeing temps like that yet no issues in terms of garbled screen or locking up. I was hoping for a cooler with lower temps as I would still like to lower them as much as possible but maintain high performing clocks. I know I am not the only one to have high temps on a regular basis so I suppose I am just surprised your card is acting the way it is on those temps. 90c is hot for sure but it isn't the 120c I thought the cards were rated at. Knowing you, you probably had a close eye on temps while reviewing the cooler so I doubt you left it running long at those temps. Why did NGOHQ get such great results on their review? I am not doubting your review just find it weird that NGOHQ gets into the late 50's where as you 90's. I could see a 5c +/- difference between reviews but not 40!
I hope all works out for you in the end as again I do feel bad for you, I really do. Do you think perhaps it isn't the core that is damaged but maybe one of the ram chips has failed causing textures to be displayed corrupt when being read from that particular IC(s)? Do you get screen corruption on everything or just quake 4? I know you said earlier in a thread that you had issues with quake 4 corruption but later ruled it out to a driver problem and not your card.
let us know what they do about the situation and whether or not they provide some sort of remedy to it.
Luckily I have connections and its being replaced as an RMA - won't say much more than that. Unfortunately when reviewing there is a much higher risk of losing hardware. I lost a 6600GT last month on a cooler Aerocool provided to me. The TIM was conductive and ended up shorting the tracers on the PCB :(
Well they even tested with the washers on so... I have no idea how they got such good results. Also consider that I test in a closed case so the ambient air getting dumped into the case from the cooler wouldnt circulate out as if it were on an open workbench. My results are usually much more indicitive of the user results - how many people actually have their PCs on an open bench? (besides EVA 2000 anyways ;) )Quote:

No biggie, I'll be back in action by next week - WITHOUT THE ACCELERO! :)
I just want to warn people that this product MAY be harmful to you video cards' health! :slapass:
sorry to hear bout the XT dnottis, many thanks for being the one to take the dive and get the warning out.
I'll just chime in with the others questioning the design. IMO take the old Silencers, add heatpipes to move the heat from the core to fins close to the exhaust point, put more copper in the thing and give the fan a wider range [silent, quiet, OC] and maybe make it thinner so SLI on boards like the SLI-DR can use it
Hey NP, thats what we are here for! :)Quote:

Very true, I know I leave my case closed when using my system and it does get quite hot inside. You guys see the new Zalman VF900? Might be another alternative to this. Still keeps air inside the case but adds 2 heatpipes to the already existing 700 line of graphics cooling.Quote:

ouch dnottis, sorry to hear so it's permanently damaaged at 90C ?
Yeah but looks like he is getting it RMA'd

someone know news about the new zalman vga cooler(VF900)?
Wow it looks like AC really went to shat this time around, I'm glad I'm going W/C...
dnottis; I really feel for your hardware issues, I've been through Three DOA DFI crossfire boards from newegg recently. I finally had enough and got a refund all $195 plus the $13 it cost to send the lump of crap back each of the three times because the P/O wouldn't ship it flat rate because the board box stuck out past the box flap half an inch every damn time. :slapass:
In the first DFI CrossFire board, would always hang on the last LED and never showed video, the second absolutely would not boot, and neither would the third. To say the least, it has been an absolute nightmare.
And no, there is nothing wrong with my other hardware it continues to work fine in my NF4.
I just ordered the Asus A8R-MVP and it better work or I am going to have a thread called "Dremel-Modded Motherboards"
Anyway, sorry to go off topic on the thread...I hope the old Artic Cooling I know pulls through and revises this bastardly joke of a cooler.
Yup: Icooler.netQuote:

and how do they go about sending them with washers?? seems a bit stupid to me... :stick:
edit: in techPowerUp!'s review the washers had been removed...
The installation of the Accelero X2 is very easy and well described in the manual. It will not take longer than 10-15 minutes. All you have to do is put on the thermal pads for the memory cooling, remove seven washers, screw down seven screws and plug in the fan connector. The installation specifically mentions in which order the screws should be tightened for optimum distribution of mounting pressure. The numbers in the image are in the order in which you are supposed screw them down.

also the fact that the washers were on there puts the core about 1/16" of an inch away from the cooler already. There was contact, much better contact after I removed the washer but by then the card was already damaged and artifacting (or locking up with a screen full of corrupt information).
What do mean you with this "washer"?
Where it located, and what are it looks like?

since this assumption no longer holds true for arctic cooling products (first the fan wiring issue and now this debacle), it would now be wise for reviewers to do what you are questioning dnottis about. (for AC products, until otherwise proven by other companies)

Come on Gnome, I understand you are just playing devils advocate but stop breaking Dnottis' balls over this. He suffered a loss and was fair and honest enough to share all details with us. I am sure if this happened to your card you would be far from impressed yourself. Perhaps because of issues like this, the final retail product will be better than it is now, not to mention as should be for us general, non review users.
i'm not trying to brake his balls or play devil's advocate... i just wanted to know if he tried anything to make the cooler work... I'm verry happy he warned about the issue and the extent of the damage caused, i just want to get as many details as i can...Quote:

I have broken 2 pieces of hardware trying to reclaim the worthless heatsinks on them. I broke an epox nforce2 vdd chip in half when I removed a heatsink attached with an artic silver5/artic epoxy mix. I bought a new one and with great difficulty solder the new vdd chip back and it worked.
I broke a 9700pro removing its heatsinks attached with 3M double sided sticky tape. The memory was obviously too much torsion and testing 3dmark2001 showed error.
Im sure that once u stick a heatsink down with thermal tape is not meant to be removed.
The last time I attached heatsinks, I used silicon thermal paste anda dab of super glue in the corner. Then force to twist it off is minimal and the super glue can be cleaned from the memory chips using a flat head screwdriver and great care.
So I wouldnt be surprised if it the memory which has failed on the card due to the use of thermal pads.
megatron
Thermal pads are non-sticky, so why should memory be damaged at all?
:eek: There may be varying degrees of stickyness but I doubt any thermal pads designed to hold something in place are completely non-sticky. Edit: 2nd thoughts maybe Im confusing it with the zalman - ur right doesnt need to be sticky for the accelero.Quote:

This made me think that it could be the memory which is borked.
My r9700pro was not even obvious that it was damaged - only came to light when using it after removing the sinks. Got a full refund on it after 2 years so not all bad.
Everyone seems to think this cooler is a step back from the original design (putting it politely). Its not all that stupid though considering conventional cpu coolers, do the same thing.
Zalman vf-900 ftw however I think.:stick:
oh I tried with the stock paste and arctic ceramique.
The problem was 1. when it shipped they had washers on the unit that should not have been there - check previous page for the email that I was sent. the core was making contact but my load temps shot up to 90 using Riva Tuner - started getting artifacts in any load test I ran... ati tool, rthdrdribl, q4, etc. I had already checked contact twice before even powering up.
the manual didnt say anythign about the washers them so i left them there.Quote:

original testing has been done with washers, but i retested without and updated everything. the difference was about 3°c. the numbers in the review are without washers
i tested with both stock TIM and arctic silver lumiere. as written in the review the difference is less than 1°C.
for the contact photos i took the stock tim one because it had squeezed the paste away so well, despite being rather thick
When does it become avalible in shops?
I was wondering have it would do, if the stock fan and chassis was removed.
And then attached a big fan 9cm or 12cm blowing on the heatsink??
I think it would do alot better, because the heatsink it self is relative big.
Are someone in to triying this?
@dnottis
i know ur getting ru card RMAd cause of connections u got.
but AC has nothing todo with this RMA? and have they apologized to you that ur card died cause they screwed up?

My X1800XT had a Zalman VF700 on the card until the Accelero arrived. As much as they want to blame it on my installation of the card, their cooler is to blame and thats the bottom line.
The NF4 is the most popular selling chipset right now and even with a the retarded design layout placing the chipset directly under the PCI-e slot AC goes about designing a cooler that exhausts downward onto the motherboard and the chipset? Is this the dumbest R&D decision ever made or is it just me? Why would you exhaust hot air onto the motherboard when you've got a tried and true layout that people exepct from you that exhausts out the back of the Case? I just dont understand the R&D department at AC sometimes.
Recall a few months ago AC released the Nv 5 Silencer Rev 3 that had the wiring harness wires reversed. I was the one that reported this to AC, their response - send me another cooler the first one must be defective. So the next one arrives and still there is no power with the default layout of the wires. Checking against stock I notice they are reversed... I call AC again and again they doubt my installation ability... until I send them pictures and their engineers confirm they :banana::banana::banana::banana:ed up. What kills me about this is that thousands of products went out the door with the wires reveresed in the wiring harness... was this product ever installed on the 7800GTX???? Is there a QA department that even tests the quality of the products they ship? ...and they assume it's me?
Anyways - I used to respect AC for their superior aftermarket GPU coolers but the last two products to come from AC have been flawed. Im quickly losing faith...
AC fooked up them washers were not mentioned in the instal guide so i take it that a big part fo the people would leave em on.
was planning on putting a AC cooler on my new 7800GT but seeing how AC treats the people that help them i wont buy one of their coolers till they grow up and buy a zalman instead.

so he agrees :p

I still stand by my comments regarding this product. I would not install another one on an X1800XT or any compatible video card I owned.
I wonder how the temps are going to be on the X1900XTX when it is released. Probably hotter due to more going on but Im hoping for a change in its design to yield cooler temps.

...And if you have the desire to dump hot air on your motherboard and surrounding areas or the extreme desire to lower your overall CPU overclocks by creating oven like ambient temps within a closed case then the Accelero is for YOU! :slap:
My load temps never broke 68 with the Zalman VF700 - do yourself a favor and either pick one of these up (http://www.newegg.com/Product/Produc...82E16835118117) or wait for the new Zalman 900 - there is really no reason anyone should have any interest in the Accelero product at this time.
I don't mean to doubt you but I still cant see how the Zalman is up to the task of an overclocked 1.48+v PE card. I had it on my XL and yea it was fine however that is a much slower, lower voltaged card. You seem to be the only one to get desireable results with that cooler as others have gotten at least the same as stock if not higher which is something I really don't want. I will wait to see how users try the VF900 on the card to see how it does as perhaps that may get slightly better results. That cooler doesn't exhaust out of the case either unfortunately. I am hoping someone will since AC isn't.
I know the Accelero is compatible with the X1900 simply due to same pcb layout and mounting holes however with the card not even out yet I can't see how they can accurately state what the cooling performance will be without even knowing the voltage used or temperature output of the new cards. I guess only time will tell. A local online shop has the X1900 listed but obviously no availability. I hope to get one by the end of this month if they are actually available to compare to my XT flashed PE.
I also find it very hard to believe, that you could have a XTPE (1,48V) card cooled by the ZalmanVF700-CU and stay under 68C at load. Mine was in the 80ish.
Im will give the 7000 i tried. Still wonder about the backplate?
Reseating can sometimes help mbm...and ol as5 never gets old :)
So does this seem to be the final verdict on the Brake-erro ? :p:

@dnottis
sucks about your card :[ least its getting replaced and thx for the info on the cooler >:O ill make sure not to purchase anything from them anytime soon ~

And it will exhaust heat out the rear, right? :p: I'm so bummed about this. My stock x1900xt can get soo loud, but not only does it "shoot out the rear", but it's VERY effective at higher speeds using Atitool.Quote:

I have installed and used at least 4 Silencer models with both ATI and NVidia cards and none of them were ever noisy - even at full tilt. The cooling was pretty impressive too.Quote:

Swapped for the zalman 700 and load is now 70s with idle at 39 and it's quiet the whole time :)
What is CCC?
So I guess we can all agree that the Ac x1/2 are just quiter versions of the stock coolers, which isn't impressive. Now im geard towards an dual NV silencer's which is still available may I remind everyone :D
