Fan Adapters?

post #1 of 6
Thread Starter 
So I recently bought some Fractal Design fans for my next build (I'll do a much better thread on all that business later). Basically my problem is this:

>They are 4 pin PWM fans.
>My fan control unit is for 3 pin fans.
>It's kinda too late to return either.

The case I'm getting has HEAPS of room for me to tuck all manner of adapters behind it and ideally I'd have each of my 6 fans plugged into each of my 6 fan controllers. I couldn't see any adapters online, but you geniuses might know something I don't redface.gif

Is there anything I can do guys?
I don't mind a bit of DIY, but I'm not really keen on any kind of wiring/soldering.

I would have bought different fans (non-pwm), but if you are keeping them you can get a bunch of 3/3 pin extensions like these. If you are into more DIY, you can re-pin the 4 pin fan connector to 3 pin. You'll have to deal with the lone pwm wire, but you can sleeve the cable, which will make the whole setup look cleaner.

Wouldn't I just be able to cut the ends off of the controller connectors and leave one of the pins hanging off to the side? Or is the PWM pin one of the middle few?

The PWM control wire is the 4th pin, typically the blue wire coming off the fan. But, its your choice, cut away if that works for you.

Oh, DON'T cut.

 

You can get a PWM harness where it draws power from Molex, draws PWM speed control from your motherboard and reports the speed of one fan back to the motherboard. Examples are here, here, and here.

 

Get one of these and your motherboard will control your fans. You won't have to waste money on a fan controller. I love hearing my TY-140 case intake fan rev up when my rig starts doing some heavy lifting. You're lucky you made a "mistake" and bought PWM fans.

 

It's nice to know FD sells PWM fans.
