5500/275 no fan?
I've got a 603e based 5500/275 PowerMac (black man!) and the CPU fan just died with a huge banging sound!

I popped the box open, and can remove the fan to verify it is indeed the little blower that is causing the problem, but my query is this -

would it be ok to run the 5500 without the fan? I'll leave the heat sink over the CPU in place, but remove or disconnect the fans power?

I'd rather not spend the money if at all possible. This is not my primary Mac, and in fact I use it solely to run a QuickCam that looks out over my backyard at night.

Any ideas?

At a minimum, you should get a 120VAC powered fan and a wall cord and hook something up to blow through the case near where the original fan was. Actually, pulling through the case might be more effective. There's a lot of heat in there -- you need something to cool it off.

Hi there

I ran my 5500 (603ev) for ages with no CPU fan without any problem. If you take the PCI slot cover off the back of the mac then the main fan will pull cool air through the back, over the chip and out the top of the case past the CRT. If you have a PCI card in the slot then you should definitely replace the fan.

Eventually under advice from these forums I did replace the fan with some generic PC fan I got from an electronics shop for $5. ( I put a PCI card in and started to do some pretty heavy audio work) Make sure it is the right voltage.

If you are doing work that is not too processor intensive then you should be OK for a while at least. The heatsink is very effective, remember Apple are geniuses at heat dissapation..........

Good luck
