Radeon HD 5870 Quiet Mod

I noticed that the squirrel cage fan in the HD 5870 can at times make a medium pitched wirr. After some messing around I realized it was the plastic shell that was very good at transmitting the noise.

So I got out some foam board and created a sound damper.

The end result is that frequencies are now isolated to much lower end of the spectrum and the video card generally remains barely audible.

This also has not yet shown to affect thermals in any way so it’s the best of both worlds at the moment.
