Well guys I screwed it up

I ordered the Arctic VGA Silencer and applied it to my Radeon 9800 Pro All-In-Wonder. Now ATI Tool reports artifacts at *default* clocks. Apparently the cooler isn't getting good contact with the GPU. I made sure to use lots of thermal goo because I was under the impression that the heatsink might not touch the GPU because the GPU socket is higher than the core by maybe half a mm or so. Is this true or not? What should I do? Do I have to tighten the clamp even more? It was moaning and groaning, I didn't want to do that.

It's not all the way down like it says to do in the instructions but it seems very secure & solidly connected. Grrrr.

Helps guys, what should I do. I have AS5 laying around, maybe I should try just re-applying the thing.

Sorry just had to vent.

So your problem is the shim (the metallic square around the core)?

I solved that by filing the base of the silencer by 0.5mm as to create a square that is smaller than the shim , so now my silencer has perfect contact with the core and doesn't touch the shim at all.

Beware that if you do that or if you remove the shim , you should take extra care when mounting the HS , radeon cores are very sensitive.

Tighten it down until the screws bottom out. Yes, it'll be tight. Yes, it'll make you nervous. But that's the way the tension mechanism is designed. It creates good contact through a flexing of the steel in the clamp.

Feel the metal of the AC-S, is it warm anywhere? On mine the metal nearest the GPU gets quite hot.

Yes the heatsink is warm. Hot, I might say. But perhaps it could be hotter.

I will try re-applying it tonight.

I put mine on my 9700pro today and had no problems; did you be sure to get all the thermal goo off before you reapplied; and you shouldnt need to put a huge layer on there. Check out how Ed applied his AS5 @ www.ngtechnik.com. You will find it under the TIM applying article. Best of luck in fixing your problem!

Watercooled NB?

Hmm whats up with all the NB cooling going on? I had a noisy little fan spinning 4-5000 rpm that I just turned off. And I havent had a single problem ever since. The tiny heatsink underneath the fan does fine. Even when running Sim City 4 with BurnIt in the background :]

System: P4 Prescott, MSI Mobo, Geforce4 Ti-4200

Just my 2 cents

Yeah, I do wonder about the watercooled NB's. Mine's (Intel D875PBZ) is quite happily PASSIVELY cooled. Easiest solution of all

On my nvidia Ti4200, I filled the depression in the top of the chip package with a thin piece of aluminum that I cut from a single use dish.

It may not be perfect, but it works a lot better than filling the gap with just paste. I wonder if this is a sloution for the 'ATI gap' as well. It will have some protective effect on the core perhaps, but it could also form a risk of shorting something if it startedto move.

I kept the shim on my radeon and fitted the vga silencer with no problems (Apart from the mounting bracket was useless) but once when fitting a zalman heatpipe to someones radeon 9800 pro we applied alot of AS3 to the core. Booted up the system and got artifacts in games etc.. anyway after a lot of messing around we found the problem was AS3 was pushed out onto the little resistors on the chips package. Cleaned it off and no problems since.
