My CPU temp is making me nervous. I recently installed a new hard disk drive, bringing it up to 5, all in my PC. That, coupled with a fanless Radeon 9800 Pro 128MB (It has two massive heatsinks on each side) I believe is what sent my CPU temp to it's record high of 75C/167F. So I took out all the hard disks and now the CPU is back where it was, idling at 58C/136F and peaking at about 63C/145F, but I need to put at least 3 hard disks inside the PC, and I would like to get the temp as low as absolutely possible. The CPU is cooled by a Zalman CNPS5100-AlCu Heat Sink & Fan, and the temp readings are from CPU Socket, not Diode. I can't get a diode reading apparently, but my case temp is 33C/91F. Should I try to get it cooled more as well? There is one condition for whatever cooling solution I employ. It has to be very, very quiet. I carefully built my PC from scratch with low noise in mind, hence the fanless graphics card, Zalman CPU cooler, etc. All ideas appreciated, thanks!
