Strange cooling problems... Help!

Well, I ordered a VGA Silencer Rev. 3 and some ramsinks from svc and they arrived this morning. I quickly opened my PC and took out my Radeon 9800 Pro (BBA) and took the stock heatsink off (on a sidenote, the chip is labeled as a R360). I then put on all of the ramsinks and then put on the VGA Silencer, following all instructions. I put the card back in my computer and booted into Windows no problem. I opened up Far Cry to make sure 3D stuff ran okay and found that there was massive artifacting. The card is clocked at its stock speeds (380/340) and it never artifacted like this before the new heatsink, so I deduced that I may have installed the new heatsink improperly.

So, I did it all over again and still ended up with the artifacts. These artifacts seem heat-related, if anything, because there is just shimmering pixels and wobbling polygons (no checkerboard stuff). I reached in my case to see how the airflow was and it seemed that no air was flowing out the back of the VGA Silencer. When I hold my hand over the air intake on the Silencer, it actually feels like the air is coming out there.

My question: is there anything I can do to reverse the flow of air or something to make it cool at least better than the stock cooling? I read through the whole "VGA Silencers Suck" thread looking for answers but I couldn't find anything useful. Is there anything I can do? :(
 
Put the original heatsink back on, and flash it to the XT BIOS. (R360=+++) assuming your RAM can handle the default speed of an XT.

Will the new bios help any with my artifacting problem? Anyways, I don't think I can use the xt bios because my card only has 128 MB of RAM
 
My understanding is that you can use the XT bios with 128MB of ram, as long as it is capable of the speed increase the BIOS defaults too. (but you do need the R360 core)

And as an XT it will have the "auto overclocking" and core temperature reporting features. (thus you can tell if it really is heat causing the artifacting)

But I would go back to the original heatsink if you can, why mess with a lower quality cooler?
