Is this power supply fan supposed to run constantly

I have a Compaq Presario 5000 Pentium 4.  Lately it has been shutting down on its own.  I noticed that the power supply fan never comes on.  In my experience, at least with store bought computers that the fans almost always run.  Never the less I tried it with another aftermarket power supply and it wouldn't even power up.  I'm not above buying another one to fit it but I just wanted to see if anyone else knew whether or not the fan should at least kick on at some point.  Thanks in advance.

Most power supplies that I've seen run the fans continuously, but there are models which are thermally controlled and don't kick on until a certain temperature is reached.  If the shutdown is caused by a nonworking power supply fan, the inside of the power supply must be very hot.  The problem is that when you experience a problem with a power supply, it can affect all the things connected to it.  Replacing the power supply and not being able to boot up may mean the motherboard has been damaged too.

I would agree with you on the motherboard having issues but once you turn everything back on the machine runs great and passes promark burnin test.  As for the power supply and the after market one not working, I've seen that before with various Dell power supplies and them needing to be an OEM power supply.

Most compaqs I know of do use legacy powersupplies, so you can't just replace it with standard models. Also, a lot of compaqs use a passively cooled CPU which does need the cooling supplied by the fan in the PSU though. So I think it should run. Try opening the PSU and then move the blades of the fan and clean out all of the dust. If after that the fan still won't run, replace the fan.

Replaced the power supply with an exact compaq supply and that fixed it.  Thanks for your assistance.
