Fan Power Distribution PCBs

post #1 of 6
Thread Starter 
I've been looking for a while for something simple, small, and convenient to power my GT2150s that will soon come in the mail... The closest I got to was Frozen-CPU's 3way DIY PCB, but I don't feel comfortable putting that much power (3 fans) on a single motherboard 3pin. Does anyone know of one of these that run on a molex connector or something?

I'll be powering 8 fans, so I need one PCB to power 5 fans, and the other powering 3 fans.

You use a non-Gigabyte board, so your mb will not supply variable Voltage. Your mb may supply control of fans through PWM. There is a PWM-controlled fan controller that then puts out variable Voltage in response to the PWM control. The power from the fans comes from PSU/Molex. I believe what you want is this.

Otherwise, for straight non-controlled power go directly from Molex.

I'm not looking for fan speed control, I'm looking for a way to power all my fans at 100%. The GT2150s I ordered were barebones, so they have nothing but two wires, voltage and ground (no tach). I don't exactly have 8 open spots for fans on my motherboard, so I need for the fans to be powered directly from the power supply. Having each fan routed for a single molex would result in an jungle of wires, so that's why I'm looking for some sort of pcb panel to neatly power the fans.

Although a fan controller would probably be the most convenient way to power the fans, I wouldn't have the space to put it in a 5.25 bay (ocupado ).


EDIT: Just found a whole different page for what I'm looking for! I was talking about something like this, but with all at 12v instead of varying voltages.

If all else fails, I can buy a sunbeam power port and unscrew the plastic casing.

Do you have a friend with a Scythe fan? They have these Molex adapters you could splice your wires into.

Or you could get one of these. Or a couple. The shipping is free so you can afford to make mistakes. Just cut the ends off and splice the wires of your bare bones fans onto it.

OTOH, from what I understand those BB fans are going to have plugs put on them. Ask in the buy thread.

Here.... This one will feed 12V to up to four fans from a single molex. Two of these and you don't have to worry about PCBs, mobo headers, etc.

Oh man - how could I forgot the completely common adapter cables?! I feel so dumb, looking for fan power PCBs
Although I'll probably end up getting ehume posted because it looks much cleaner...
+rep to ya both! Still can't believe I forgot these existed!
