What the hell... does this look right to you?

post #1 of 11
Thread Starter 
The Molex connector on the case fan I just bought has 2 pins instead of 4... I have never seen anything like this before. Is this how it is supposed to be?



Also, there is a small pin with 3 holes also on the casefan. Should I attach the molex or the 3 pin connector to my case? Or both?

2 pins are sufficient to power most fans

Do I use the 3 pin as well as the Molex connecter? Or just plug one of them in?

Red is power, black is ground, and yellow is speed monitor. If the small connector has all 3 wires, use it and ignore the molex. If it only has the yellow wire, you can use both. The mobo will monitor the speed, and the PSU will power the fan directly.

The reason that molex connector only has 2 wires is because it doesn't have a pass-through connector on the other end, and red and black are all a fan needs. It's not the standard config, but I've seen a few like that before.
