open it up and clean it tomorrow.
Where fan 2 and 3 are 0 RPM's does that mean there are no fans or they have
not kicked in?
thanks Bruce
Fans read zero, when the dynamic range of the readout is exceeded.
The fan measurement method, measures the time between two fan
tachometer signal pulses. A counter is used to measure the time
interval, as shown here.

<----------->
If the counter measuring time overflows, because the pulses
are too far apart, the software interprets that as "0 RPM".
If the pulses were missing entirely, the same thing would happen -
the counter would overflow, and the software wouldn't know if the
pulse was missing, or merely late.
It could be, that the fan measurement only goes down to 500RPM, and
anything below 500RPM is read out as zero.
With regard to your temps, you generally verify them with a computing
load present. If the cooling system is not able to cope with the
heat under load, then your computer needs some work done on it
(cleaning, reseating CPU, new paste or whatever). It is hard to
judge just what is normal/acceptable, because an automated fan
controller can have a relative high set point for temperature.
So the temps listed above, at idle, may be with the CPU fan
switched off to reduce noise. They could, for example, be
attempting to thermoregulate to 60C.
(Prime95 will load a computer to 100%. The "Torture Test" also
verifies the correctness of the calculations it is doing, and this
test is a favorite of overclockers, as a means of seeing whether
their adjustments are correct or not. If one of my computers will
run this for four hours, with zero errors detected, then it is
ready to be used for real work. This will make the CPU warm.
If your computer shuts off, in say 30 seconds, then you know
your cooling needs work.)
