Hello Matt - 

CA>> I have a 233mhz machine that only needs a new fan for the
CA>> powersupply (very thin muffin fan not easy to find I
CA>> suspect) and I can have that machine running only Linux.
CA>> KNOPPIX would be a good starting place. :-) 

MM> When I 'reconditioned' this power supply from the junk
MM> pile, I remembered how often many of the fans need
MM> replacing and/or bearing re-oiling. I took the fan out of
MM> the case and mounted it on the back, rather than the
MM> inside. Now I can access or replace the fan _without_
MM> having to open the machine, remove and disassemble the PS,
MM> and all that other mess. 

MM> Applied to your situation, you wouldn't need a 'very thin'
MM> fan for a replacement, as any one that matched the
MM> screwholes would work fine. 

MM> In this instance, I _did_ have to play with the screwholes
MM> a little, as the original design called for the screws to
MM> pass through the metal case and thread into the plastic
MM> fan. With the external fan, the screws now have to pass
MM> through the plastic fan and thread into the metal case. 

MM> I enlarged the holes in the relatively soft plastic fan so
MM> I could use larger size sheet metal screws that would grip
MM> in the existing holes in the case. Alternately, I could
MM> have used smaller screws and put four of those little
MM> automotive clip-on thread things on the metal case. 

Apparently "Great minds think alike"! :-) 

I did use duct tape to put a muffin fan outside the back of the
tower where the vents for the ps are to test the system to see
if it was 'fried' yet or not. The previous owner hadn't noticed
the ps fan had stopped working but had mentioned the problem
seemed to be overheating. After checking to see that the CPU
fan was working I noticed the ps fan wasn't. 

I have considered doing what you describe but if I could locate
a thin enough muffin fan the repair would be invisible (sort
of). I've been otherwise occupied lately and neglecting _that_
project a bit. But it's waiting patiently for me to get back to
it. ;-)
