By coincidence I have two of these systems - both with different issues.
Machine 1:
This one I'm most interested in and was full of bad caps. The PSU had every capacitor bulging (including mains cap) apart from two 470uf 16v, I believe this is what caused the caps on the mobo to bulge and cook. All caps on the motherboard seem to be 10mm or below.
I've replaced 4 bulging OST RLX 1500uf 16v 10mm with equivalent Panasonic FC but 12.5mm in diameter so they're sitting a bit crooked. I've also replaced 2 bulging OST RLX 1500uf 10v with equivalent Panasonic FM 10mm. - it still boots, so that's good.
I've got 6 visibly OK OST RLS 3300uf 10v 2150ma ripple I want to replace, but they have to be 10mm else they won't fit. I cannot for the life of me find anything that matches this. The closest I have come is Panasonic FK (the datasheet seems to suggest they're better than FC) 2700uf 10v 2140ma. I'm assuming this is the CPU VRM section, do you reckon I can get away with the lower capacitance?
Machine 2:
Everything capacitor wise in there looks good and it runs fine, when it's not overheating.
The CPU fan was connected one of the fan headers on the motherboard. The fan doesn't work on another PC, no fans work on any of the 3 fan headers on the motherboard.
Anyone have any ideas on where I would start looking to get the fan headers working? Any specific make of chip or is it likely to be a resistor?
