OK I took of the HSF from my x800gt to find out what core it was, and when I took it off I noticed there was massive amounts of thermal paste. When I put it back on, I put AS5 on the heatsink then wiped off the excess with lint-free rags, then applied AS5 to the GPU like you would to an open-die processor.

Now when I boot up my computer, the back of the card (opposite from the GPU) gets so hot I almost burned myself on it, and the HSF doesn't even feel warm. The computer crashes after about 2 minutes.

Should I have bathed the HSF/GPU with thermal paste like the assemblers did? I thought too much paste was bad
.

Please Help.

It seemed like they used a thermal tape or adhesive more than a paste on the HS of the last ATI card I dissassembled (X700 Pro) and just smooshed it back together after inspecting the card (HS seemed loose--I would lose video intermittently--reattaching it seemed to fix this...)It could be that their tolerances are bigger than for CPU HS

The stuff that was on mine wasn't sticky at all, it was a bright silver, almost foamy paste. A lot less ticky than AS5.

I just took off the HSF again, and some of the AS5 turned white...... Did I burn the AS5?

And what should I do, just wipe the old stuff off and reapply using alot more compund. Because when it had gollops of paste on it before the temps were fine, then when I only used a little bit, the temps skyrocketed.

I'm also going to file down the little foam feet like nagle suggested in that thread Zip linked.

Should the spring loaded screws be tight, really tight, a bit loose.......

I know they have to be equal but how tight should they be?

EDIT: The filing isn't going to happen. I found out the little feet on my card are foam, not rubber, so they're really squishy. Shweet.

Tighten them to a stop by hand, then back off 1/4 turn on each one.

Ok I loaded on the AS5, hand-tightened to stop, quarter turn back, and it's working now.

My new problem is that Windows, in all it's wisdom, decided to delete 5 key d.ll while doing a diskcheck. Now I have to wait 45 minutes while it reinstalls.


If it isn't one thing....

Thanks for your help guys.
