For anyone about to or is going to embark on installing the Accelero Hybrid...

post #1 of 8
Thread Starter 
I am going to use this thread for reference purposes, and to help anyone having trouble with high temps/overheating with this cooling device.

I just got done installing this cooling device on my GTX 670 FTW. To make a long story short, it was a nightmare. They have to make the installation of these things more easy, because you can very easily forget a part (this is partly because the instruction manual is god awful) and because there are things that the manufacturer could have preinstalled that only made the process more cumbersome.

Anyway, I booted up my computer and the temps were ATROCIOUS. I was hitting 80 degrees at 60% fan speed. Then, two minutes later, my computer powered out from the GPU overheating.

From experience with these things, I knew that there could be a few reasons: 1) not enough TIM/bad TIM spread/placement 2) Bad waterblock placement/mounted incorrectly 3) A faulty device.

When I took it out of my PC (and trust me, it is a horrible feeling when you have to pull out a device like this knowing that you would have to backtrack and relive the nightmare of putting it together), I first looked at whether my block was making good contact with the GPU. What I noticed is that there was about a mm of space between the two, with the TIM goo sort of holding it together. I heard some people say that there should be a bit of a gap between the block and the gpu...who knows..

What I found was that after removing the white spacers from the waterblock, the block and GPU were making perfect contact (there was no gap).

I put the device back in, booted it up, and my temps were back down to below average.

TL;DR version: If you are having overheating issues with the Accelero Hybrid, remove the four spacers on the waterblock so that the block and the GPU are mashed together.

1 question, did you read over the instructions before installing it, I mean really read them? Just gotta make that clear before you go saying that the installation is flawed because of the provided directions.

I devoted the entire day to installing this thing, so of course I read the instructions. The point of this thread is to alert people to possible solutions to overheating issues, and one of the issues I found is that the spacers prevented the block from making contact with the GPU die. Obviously some people were and are fortunate enough not to have problems, but I did.

is this a card with or without an IHS?

There seem to be a few similar issues with "regular" waterblocks on certain cards also.... it looks as if certain "reference design" cards are rather only 99 % reference vs 100% reference rolleyes.gif

But yeah, from other places on the net, the installation of this gizmo is not for the fainthearted or impatient hands-a-shaking-alcoholic ADHD 'ers smile.gif

all 6 and 7 series cards from nvidia have no heat spreaders. no IHS.

I installed the Hybrid Cooler PERFECTLY on my GTX 670 the first time I tried it. It's just a matter of being meticulous about the instructions. There is NO problem with this cooler, I assure you that, except for the price. I'm guessing the installation of the white rubber rings on your card weren't in the proper place.

When I installed the hybrid on my gtx 680, it seemed okay enough.. watched the youtube videos and followed the instructions included. Just took a long time.

I was going to go with a Dwood bracket, but after he had stopped sales, and someone on kijiji was selling the hybrid kit for only 60 bucks, I couldnt resist.

It pretty much cut my temps in half overall.

Right. I got it for a steal at ebay too, BNIB. I really think the info in the OP is not accurate for others to follow as a "warning".
