I recently replaced my power supply (400 watts) with an Antec
Smartpower 400 watt supply.

I've never noticed it before but when I powered the computer up
the heatsink fan was not running. The case has one fan and of
course the power supply has another. It seems to pull air from
the outside and direct it to the motherboard.

Does the heatsink only power on when it is necessary or
is it supposed to run all the time?

Thank you.

Depends. The fan may be temperature-controlled by the motherboard. If it
plugs into the motherboard, check your BIOS setup options and see if there
are settings for fan control. If the fan plugs directly into the power
supply's connectors, then the fan might be bad.

Thank you Thor. I'll check into that.

Heatsink fan? Are you refering the CPU heatsink fan?
It should turn on if you power up your system.
It should be running all the time but it might stop running in standby
mode (depend the Power Management thingy in BIOS).

It wasn't working when I powered up the computer. I'm going to check
the BIOS. Thanks.
