Power supply has fan connector?

post #1 of 23
Thread Starter 
Ok, so I have this pretty old enermax power supply from '06. I want to build a cheapo htpc, so I dug it out of the garage. I took it out and the first thing I noticed was the fan connector that that branches out of the cpu 12v connector. Where am I supposed to plug this? Into the fan header or leave it dangling? Here are the pics. Sorry about the quality, my camera is broken right now, so I used my phone.

It has two wires, but three holes. Case fans have 3 wires and three holes. hmm..

Well the fan spins without plugging in the connector. Perhaps it supplies extra power??

looks like someone has wrapped it with the other connectors for "cable management " purposes.

Like most connectors if you don't need it, don't use it. smile.gif
Think you are good to go
