The CPU is an Intel Core 2 Duo, E6400, stock cooling. Below is a snapshot from CPUID Hardware Monitor. Also, the "ambient" temperature of the room is somewhere around 25°C (77°F). I have applied a thin layer (as always) of Arctic Silver 5, in the BIOS of the motherboard (ASUS P5B) I have disabled the option that allows the cpu to run under the 2.13GHz when not under load (idle). Should I enable this option? Is the temperature normal for the CPU, taking in consideration the room temperature? Other info: Case - Coolermaster Mystique with 2 fans (1 in front, 1 in the rear) sucks in cold air, and blows it out from the rear. I think they are both 140(?) fans, both are coolermaster fans. Settings for fans - chassie and CPU are set to "performance", but I did not hear an increase of fan speed.
