Arctic Cooling Accelero X1800XT Cooler

[Ator]

stock is 2.097v

x1800 oc'ing tool displays incorrect mem voltage

Yeah I know. That was with ATI Tool. I could barely hit 860 before playing with the voltages.

gonna say it cos hopefully someone sometime will listen.

a lot of users don't use pci cards, 99%, well, 99.999999% of people don't use sli, therefore a shedload of users have soooo much space under their gfx card for a MASSIVE and proper heatsink. won't for the love of god someone design an easy to attach huge alu sink with a proper fan. these blower style sideways air moving fans move almost no air and are pretty much just crap.

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?

You mean doing what I've done here with an sp97?

Oh finally. I have been looking everywhere for news on a new ATI Silencer for the X1800 but found nothing till now and of course on this forum. I agree with the air not being exhausted out of the case but you know? If the temps and noise drop as much as the NGOHQ review say they do I will still get one. 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.

It's doable
I'm running a TTBT on the bottom card of my 7800GT SLI setup. I just had to to bend the heatpipes a little and had to make a custom holddown.

basically yes, but i'm talking about something commercially available with no difficulties mounting, no jury rigging, something as easy to mount in 2 minutes as a zalman gpu sink. something along the lines of xp120 would be great as its so light and cools extremely well. with the xp97, IIRC its a huge lump of copper , heavy and not something you'd maybe want pulling down on a gfx card. but thats the thing, ANY proper cpu styled sink will simply crap all over any current gfx cooling stock or 3rd party thats available right now(ignoring watercooling).

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!

[Hicks]

Totally agree Drunken master. 10CFM of air is pathetic.

Lets see some results Dnottis!

[Mongoose420]

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

[Vapor]

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?

[dnottis]

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?

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!

[200%absolut]

Really a bad news
Manufacturers must think about making some really cooler not amazing heatsink without fan....

[Cornelious0_0]

Ouch...that's all I've gotta say.

[trakslacker]

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.

[Hicks]

Oh dear.

[MadMikeSS]

man that really sucks.

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.

[IvanAndreevich]

That looks like a crap idea. Why not make a new Silencer-design product that is more flexible with some heatpipes and more fins? The idea is nice compared to pushing the air into the PCI slots

[CrazyXP1700]

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...

[scampi]

sorry guys, but I don't understand what is "washers"(look my sign )
what is it?

[cantankerous]

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.

Well I now have crazy artifacts as soon as it gets hot. Running Quake4 in the nexus hub once it hits about 63 deg c now the whole screen just goes garbled. The reason this happened, I believe, is that when we first installed it with the washers that came installed on the base, there was bad contact. This caused the GPU to get close to 90 deg c. 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??

[dnottis]

Well here is the email received about this....

[robin]

damn, i was waiting for a cooler from ac and now this.. ah crap, going to get a vf700-cu..
