Control Speed of Fans

post #1 of 8
Thread Starter 
Hey OCN,
I have two old 120mm fans from my ancient rig. They have four pins, and my DFI mobo only have 3 pin sockets except the CPU cooler slot. I know when you attach four-pin fan into 3-pin slot, it'll go max speed. Is there a program or sort to control the speed?

I think the DFI boards have built-in fan controllers in the BIOS (but don't quote me on that). If not, Speedfan would be a good application to start with.

Speedfan doesn't seem to work.

Honestly, you will probably need to buy yourself a fan controller that will fit in your DVD drive bay and then hook each fan up to a knob and then control it from there manually. That's about the only 100% full proof way I know of to control a fan.

Very nice fan controller.

I bought one a while back, fits in a floppy drive and works really well. Has 3 fan controllers, the last knob is a illumination controller, which doesn't really work... Haha.

Anyway, has 3 Molex connectors, those are the 4 pin, about 1 inch wide connectors, as well as 3 PWM connectors (those are the centimeter wide 3 pin connectors).

I've used it for quite a while now and have had no problems. Connects right to your PSU and you get a large amount of control on the fan speed.
