I bought a new cpu fan today. Cpu temp dropped 20 degrees :-)
My cpu was only running at 140, but I am paranoid about losing a fan now. The last 3 vid cards I had fail on me failed because the fan quit. I verified at the shop that they install these fans at about 2400 rpm. Mine was running at 1800 rpm.
For some reason the old fan didnt have the manual speed adjustment attached. The new one is running at about 3000rpm, should probably turn that down a bit.
Thanks for that link, I do like being able to check the cpu temp w/o having to do a restart.
