Suggestions for quieting a modified ATI 8500 AIW

Post by windmiller » Fri Oct 29, 2004 3:20 pm

I added a Mighty Mite HSF from 1coolpc.com about a year ago and I think I used too much adhesive and the heatsink is stuck. The fan is too loud so I am trying to find a good solution to quiet it down but I cannot take off the heatsink. The fan is 45x10mm.

Any ideas?? I dont know of any quiet 45mm fans. I have a old PII heatsin that is about 8 inches long and 3 inches wide and 1 tall. Could I place it on top of the ccurrent heatsink and get away without a fan?

I really don't think you can do that. What does that heatsink look like? If it's like a typical VGA HSF with the fan centered on the GPU, and a flat space underneath it, you could attach a heatsink there.

try putting the heatsink into the freezer for like 30 min or like an hour... then try to pry it off, worked for me when i took off a glued on fan for a tnt2 card.

if not try a pci slot cooler from vantec. or a zalman pci thingy that hangs off the pci screws. lol sorry im really busy no time to link :(

stacking heatsinks on top of each other is generally bad (too much thermal resistance between them). but it depends on your setup... do you have a pic?

here is a crummy pic of what i did with my AIW 7500

i just took off the stock fan but left the stock heatsink. then i rigged an 80mm panaflo in front of it with a pci cover and some zip ties. it runs at 5V and is inaudible outside the case.

You're just refering attaching it to the top of the fins, not a flat centre, right?

Two layers of tim are used on CPU's. But if you're feeling very brave, you could try welding another heatsink to the base of that one.

I might try to pry it off via Freezer Method. The heatsink I have is one of those long ones with a fan in the middle, pretty big.

Flyingsherpa, I was thinking on using a fan in the same way, I have one of those arms, I just need to get a good silent fan. Ill post after I try the freezer trick. Thanks for all the ideas and info!

I cooled my 8500 (250mhz version) with a zalman cm17 heatsink so now it is passive cooled, no noice. It can get hot but it works even with heavy 3d gaming

I modded an old CPU heatsink and put it on my Radeon 9000 Pro AIW:

And it works a treat. Active cooling on these is not necessary as long as you have reasonable case airflow.
