My fiance just put together a Pentium 4/2.4 GHz system for the first time, with an Asus P4PE motherboard. We were monitoring the temperature with the included Asus PC Probe software, and the temperature reads 38 degrees. But in the BIOS settings, the temperature reads 44 degrees...? Also, the CPU fan speed is 2700 RPM (according to both the BIOS and Asus PC Probe). We thought the fan speed was too low, and tried to speed it up through the BIOS, but it would stay at 2700 RPM.. The CPU fan is connected correctly, and is spinning. We also have 2 case fans running. Bottom line is, is the CPU cool enough? Should we worry?
