A few weeks ago I upgraded my Matrox g550 to an ATI 9600XT. Since then that bloody whine coming off the video card fan has driven me nuts. To the point to where I had the card all packed up today ready to return it. I get to MicroCenter and figure I'll shop around first. To my surprise and joy they had the Zalman ZM80C-HP and cheaper than anywhere online I might add. It's working great so far. The only mod I had to do was with the NB heatsink (Orb looking thing on the IS7). I had to chop the fins down a bit. I was going to go with Zalman's nb cooler as well, but no one had thermal adhesive. Oh well. I'm back to my nice quiet 92mm cpu fan and a 120mm quiet exhaust fan. It's nice to be able to think over the computer noise again.
