I have a fairly new PC on which the CPU fan broke. After some 'help' from a third party the CPU itself lost a pin. Replaced the P4 and put a new well specified heat sink & CPU fan in. Added a case fan.
After running CPU intensive applications for a period the machine shuts off abruptly and will not restart for 10 - 30 minutes, then it works fine. The CPU temperature fluctuates between 40 and 80 but from what I read this is not a problem as the CPU clock speed gradually drops as the temperature rises. Right ?
CheckIt (admitedly fairly trivial) CPU tests show no fault. The fan speeds seem to correctly increase with temperature. Could a CPU fault be the cause ? Is 80 degrees really too hot ?
Can I trust the temperature guage on the app which came with the mobo ?
