How do i power these fans

post #1 of 8
Thread Starter 


can i buttsplice them to molex connectors and then daisy chain them to my power supply>?

edit: the blue ones, they are .12 .12 and .25 amp. the .25 amp has a led on it.
the Tt fan has a regular 3 pin connector so ive got a 3pin header to molex so im fine with that one

is there like a cheap fan controller that will plug right into a wall socket? I don't really want to mess up my system with these.

you could buy aload of these 3 pin to molex and mod the end of the new cables to take the 2 pin on the fan.

I am really liking the idea of powering these fans from another wall socket, but if i have to connect them to my PSU how would I go about it with this stuff

I don't understand why you would want to get power from outside your case when you can use the power that is there. Just get some 3pin to molex adapters.

You are going to have to buy something to hook these up to your wall so why not just buy a few fan cable adapters.

Well for the molex side:

RED WIRE = +12V
BLACK WIRE = 0V or Ground (GND)
YELLOW WIRE = +5V
You will just need to wire up so the red wire on the fans are connected to teh red wire terminal of the molex connector.

Alternativly if you want to run them at 5 V connect the RED wire on the fan to the yellow wire terminal of the molex (4 pin)

PS - you really dont need to connect the fans to an wall or any external power supply. THe only benefit I can see is if you want to turn them off in which case just fit a switch to the fans like so.

Good luck
