Hey guys i need some help with a fan controller i bought.

This is it

I used the fan controller molex straight into the PSU molex then off the fan controller molex to my case fan, then the case fan 3pin to the fan controller, i have also tried not using the case fan molex and just the 3pin but the fan doesn't even spin

Here is the specs of the Fan Controller

Specifications:

Voltage of Fan 1, Fan 2, Fan 3, Fan 4 is 6V to 12V
Output power:10W
Dimension: 10.1 x 9.5 x 2.5cm
Fan interface:3.0 4pin port
Connecting line:40cm
Max output current:2.8A
Color of LED: Blue

I only have one fan that has a Molex connection and a 3pin connection, the fan spins but the fan controller doesnt seem to do anything with the fan speed.

anyone any ideas ?

What exactly are you trying to control with this though? What connections does it have?

If it has a Molex and a 3 pin fan connector like that one appears to have on the side panel then the only way you can easily control that is by plugging the 3 pin fan connector into your fan controller and adjusting to suit. If you plug in the Molex it'll have 12v all the time.

I want to control 3 of my case fans, they all have Molex connectors but one has a Molex and a 3pin connection, though the 3pin does not control or power the fan, so i am not sure why this fan has both connectors on it.
