Is 45 degrees Celcius at idle an OK temp?

How hot is too hot?

    Accepted Solution

    From Intel:

    This page is the thermal spec (refers to chassis temperature):

    This is a page that provides specification (including thermal) for all their CPUs:

    Locate your CPU from this list (from your description there are a few that match, hence I haven't given a direct link).  The thermal spec of a CPU is the maximum temperature at which it is designed to reliably perform (usually around 69 degrees for your CPU).

    From the above, I wouldn't be concerned over your CPU idle temp.  It would be worth running a CPU burn-in test though - the critical temperature point is how hot the CPU is when being used at 100%.  So long as this remains below the thermal spec your system is fine.

    I use this burn-in software, though pretty much all CPU burn-in software does the same thing (loads the CPU as much as possible):
