I bought the lampoon fc5-v2 fan controller to controll my case fans, but this fan controller doesnot work with my 3-pin case fans from sharkoon. I can confirm that the fan controller does work, it will spin up my 4-pin cpu fan if connected.


some relevant info:

case: sharkoon DG7000 (red)

fan controller: Lampoon fc5-v2

case fans: 3 stock scharkoon 3-pin LED case fans

cpu fan: 4-pin coolermaster fan (no LED)


The main problem is that I cant spin up my case fans, once connected and powered up, I can only controll the intensity of the LED's but the fan blades wont spin up, not even at 12volts. I tried spinning the blades up by hand but that also doesnt work. The fan controller can support 30watts per channel and the fans are just 0,25 Amps so that means 3 watt per fan, that should not be a problem. If the case fans are connected via a molex to the psu, they do spin up and work propperly. The fan controller is made for 3-pin fans, but also works for 4-pin fans. 


I want to know if this is a compatibility issue, and if it would help to buy other fans, or if there is a way to use these fans with this fan controller.

Any other sollution to my problem would also be apriciated



Thank you in advance,
