AMD Sempron 2200+ @ 2ghz. I'm using Speedfan to monitor temps. I read that that diode sensors are more accurate in sensing cpu temps. My mobo is ECS K7VTA3 v6.0. Setting sensor to thermisistor temperature reads 48c, but when i set the sensor to diode it reads 39c, then drops to 35 after awhile. Which sensor should i use? My HSF is the Coolermaster Aero 7 Lite.
