Is the CPU too hot?

[happymac.support]

Ok, I cleaned out the computer. Now, the computer is around 45C at
idle and not matter what I'm doing, it doesnt go over 52C. The fan RPM
also stays around 1800RPM. Is this stable?

Thanks for all your help

Thanks again. I have noticed now that the machine is so quiet. Before,
I could hear it like a jet engine 4 rooms away. Now I cant even tell
that its running. I also noticed that the processor is so much faster
and smoother with intensive 3D games now. (By the way, the motherboard
temperature only changed by 2 degrees. Now its 39C, but according to
SpeedFan, 39C is perfectly normal). Also, you know that "Ventiliation
holes on back of case" pic I uploaded. Those holes are actually
exhaust for an extra fan that can be added. There are 4 holes on the
corners to screw in another fan. I will add a rear case fan if needed
later.

Thanks once again

52C is low enough, yes, but you should test at full load,
something like Prime95's Torture Test, large in-place FFTs
setting. Also factor for any addt'l room temp increase if
the room gets hotter in summer, or even winter (proximity to
a heat source).

Yeah, I think I might try Prime95 later (its something like you have
to run the test for 24 hours and if it remains stable without any
errors, then you have a stable system, right?). Also, you know, if its
52-53C at fan speed 1890RPM, then if I increased the threshhold a bit
to 3000RPM, it would run even cooler right? Of course, doing this does
have its disadvantages. It would probably wear out the fans faster.

Thanks

BTW, at 60% CPU usage the temp was 58-59C.
