I started out searching for a low temp after reading some of the posts on here about people have like 32deg processor temps and such. But then I realized that I don’t care, and a little heat is well worth it if you can have a quiet computer. Current setup is: SilverStone LC03B HTPC Case (80mm intake fan, 60mm exhaust fan) Enermax 350 Watt Power Supply with 2 8mm Cooling Fans - Whisper Quiet Thermaltake Silent Boost CPU Fan Aopen AK79D-400Max (nForce 2) Mother Board AMD Athlon 2500+ XP Hynix 512MB PC3200 DDR Samsung 160GB SATA Hard Drive Radeon 9000pro Video Card, with broken fan NEC 2150a DVD-RW TwinHan 1020A DVB Card I made a simple fan controller for the 2 case fans, with a single pole double throw (SPDT) center off switch, wired it up so I can run the fans at 12v, 5v, or 0v CPU fan is set to run at 75% speed in the bios. The result, the computer is quiet. The temps are a little bit higher after switching to this HTPC case, but I can live with it. Idle, 30min Average (MBM5) CPU – 47 Case – 42 Prime95 Torture test, 30min Average (MBM5) CPU – 50 Case – 43 Both tests were done with the case fans set to 5v, this makes them virtually silent. CPU fan is spinning at 2175rpm, power supply fans are running at 1600RPM. Case temp seems high, but even with side off and more fans it was always up around 40, I assume the onboard temp sensor is out of wack. Do you guys use the onboard temp sensors or stick on ones that might have came with a fan controller or something?
