Hi,
I am in the process of building my own water cooled computer. My main reason is to reduce the noise my computer is making.
I would like to silence the PSU fan. Every new fan I put inside the PSU is silent for the first few months, but they all start to rattle after that (ball and sleeve types).
Inside the 300W PSU there are two heatsinks and each heatsink has 3 power transistors (they could be FET's, but who cares... :) ) attached to them. I plan to replace the heatsinks with a waterblock.
Now my questions:
I hope these 6 power transistors are the only things that really need active air cooling. Does anyone know if the transfo needs the fan? Any other parts? I'll probable find out when the PSU dies after 30 minutes or so, but I would like to prevent that...
Is there a web/ftpsite with a simple schematic to send the ATX PSU a 'power on' signal so I could stress test the PSU without an expensive MB attached?
PS: The power transistors are electrically isolated from the heatsink, I plan to do the same for the waterblock. I know this is necessary.
