Howard;
I believe most cpu fans have traditionally run constantly, but some
motherboards
can stop the fan when the system enters suspend mode.
The cpu fan has to be plugged into a "controlled" cpu fan header on the mobo
for this
feature to work.
On the ones I have seen, there are settings in bios to enable/disable this
feature.
I was surprised the first time I saw this, but the heatsink wasn't warm to
the touch.
As soon as I moved the mouse the cpu fan kicked back on.
I have also seen variable rpm fans that have a thermistor or "thermostat"
that varies the fan speed depending on the temp. of the cpu.
The lastest breed of cpus from Intel and AMD run very hot and require a
heatsink/fan to avoid "frying" the cpu within a few seconds, but in suspend
mode very little heat seems to be generated.
