Small PWM fan controller?

Meaker · 5 May 2015 at 06:17

Is anyone aware of a small fan controller that will take a molex or SATA power connection and drive one or more 4 pin PWM devices?

Phobya do one with 8 fans headers on it. Google Phobya 8x 4-Pin Splitter PWM.

EDIT: Never mind I can use my GPU for the control, awesome. Thanks for the help.

Careful with that. It can't handle a lot of power by itself. Best to still get a powered PWM splitter.

The Phobya 8X splitter PCB is fantastic,small versitile,dirt cheap. Better than any other 'hub'.

Cannot recommend enough

It's a re-model of the Swiftech version actually, and Cooler Master has a similar one based off it too. All versions are great for the money!

I'll use a splitter of some kind, the gpu power line won't even be connected. I only need 3 devices, 2 fans and a pump so i don't need anything too fancy.

See if they all share a similar PWM duty cycle and (normalized) RPM response curve. If not, they may not run as you expected.

Incidentally, I don't suppose you are the same Meaker as on NBR?

they will work with pwm pump aswell ?

It depends on the PWM controller and the specific pump.Many fan controllers dont provide the wattage needed per channel to power a D5 for instance.
