I decided to try to make my 5900 quieter by using a single 80mm panaflo fan vs. 2 small ones in my BFG. I removed the chrome cover and strapped the fan on using cable ties thru the screw holes in the copper. I also used some arctic silver on the ram and gpu. It seems quieter now, but my temps are higher by a degree or two. Do you think that it's because I'm blowing air onto it as opposed to drawing it off? Anyone else try something like this?
