In my opinion that is being excessively conservative. I do not know
of any CPU that is *rated* at less than 60 degrees, and many Intel
CPUs are rated at 70 degrees or higher. (To me, "rated" means the
manufacturer claims it will keep working correctly.) In my opinion
the main thing you have to worry about is how much hotter the inside
of the chip is than what your probe (outside the chip) is measuring.
I use a wild-eyed-guess of 5-8 degrees for this difference.
In my own experience, I have seen CPUs run for years at above 50 degrees,
and have *not* seen any CPUs stop working at even a measured 62 degrees.
In fact, I consider your temperature reading of 42 degrees to be *low*.
The torture-test mode of 'prime' should soon detect any CPU that
misbehaves (for instance, because of heat). If you do not get any
errors in 48 hours of running 'prime' (with room temperature as hot
as you will ever have it) then my suggestion is to *not* worry about
CPU temperature.
