Problem with fan swap on old generic PSU
Posted: Fri May 19, 2006 9:29 pm
I busy rebuilding one of my older machines for my grandfather to play flight sims on. The system has an old 300-400W PSU and the fan (80mm) had a worn bearing. I opened the PSU case for two reasons 1) to replace the fan, and 2) cut a hole for a duct that will suck air through the Thermaltake SilentBoost and exhaust out through the PSU. (Have to, the cheap $14 mATX didn't have an exhaust!)
The fan iself is wired to the PSU, I clipped the wires, removed the fan, and taped the wires up out of the way. I then installed a YL 80mm I had lying around. The problem is the PSU won't boot without the fan circuit being closed.
So my question is: how do I get the PSU to power on without the fan connected? I didn't think it would be a good idea to simply short the wires, so do I use a resistor or something? I currently have the fan wired into the circuit, but I would like to hook up a fanmate between it and the motherboard in the future.
Thanks in advance, I'm sure my grandpa will be happy when he gets his new box with the amazing power of an AMD XP 1400+ and...OOOH!... a GeForce 2 card! I'll likewise be happy when I take his old PC (400Mhz eMachine) and make it into a NAS for my network.
