Arctic Cooling Accelero X1800XT Cooler

[cantankerous]

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.

[chinkgai]

let us know what they do about the situation and whether or not they provide some sort of remedy to it.

[dnottis]

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 )

Yes I had Q4 corruption but I find Nexus Hub to push the graphics card very hard and Ive seen the hottest temps if I sit on that board for about 10 mins. I should've mentioned that I am getting corruption in anything that pushes the card, not just Q4 - 3d mark, ATI Tool artifact scanner, Q4 on boards that push it, RTHDRIBL - basically anything that really pushed the card would just cause the screen to kick to garbled information then freeze the PC.

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!

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!

[dinos22]

damn man that's no good......hope it all works out for ya and a real shame what AC's been doing lately....not good at all

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.

[mbm]

Dont think putting on some heatpipes will make that much a difference.
If we cant get an exhaust cooler, we need a big copper heatsink and attach a 9cm or even 12cm fan on

[eva2000]

ouch dnottis, sorry to hear so it's permanently damaaged at 90C ?

[IvanAndreevich]

Yeah but looks like he is getting it RMA'd

[dnottis]

Yeah but looks like he is getting it RMA'd

its getting "taken care of"

[cantankerous]

The 90c mark is what surprises me too. I am not entirely surprised the card is borked although they seem pretty robust and can take a beating, it was the fact that at only 90c. I thought they were rated much higher which was what caused me to comment like I did above about the situation.

[scampi]

someone know news about the new zalman vga cooler(VF900)?

[TekXoID]

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.

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.net


If your Simplified Chinese is even worse than you English ( ), here’s a translated version.

how does a company go about making such ty heatsinks when they used to be good quality???

and how do they go about sending them with washers?? seems a bit stupid to me...

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.

Maybe they went back and edited the review after they received the email.

didn't you check if the contact was good befor burn-testing ?

[dnottis]

I mentioned that I did in the inital post about the problems. There was contact however they had so much thermal compound on the cooler base....

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).

[Kasparz]

What do mean you with this "washer"?
Where it located, and what are it looks like?

[dnottis]

Please read the entire thread - these questions have been answered already.

so you didn't try the, clean all thermal paste, re-apply razorthin amount on the core, test contact ?

generally reviewers test the equipment as it is, before removing the included stuff to replace it with "better" stuff to test before/after

when you receive these things for review, i know its not guaranteed to be the best piece of equipment evAR, but it would be assumed that its at least safe to install in the form it was sent in...

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)

but he claims experiencing issues during a decent period a time... he didn't change anything when the issues first started ?
