My box has 3 fans, one on the case blowing from outside=>inside,
one in the power supply and one on the CPU.
In the evening, i will have the case/board inside blown/cleaned with air,
i am gonna close the case, and i am gonna tune BIOS to fail-safe settings.
Apart from that, i would like to have a reliable tool to monitor temperature.
Is there anything in mind?
