Swifttech mcp655 modified for pwm (by frozen CPU) with a 3-pin fan controller?

I have one of these,

It has a molex connector to power it and a 4-pin pwm header to control the speed. I was considering using my 3pin fan controller to control it. I was thinking I could use one of these ,

a female molex to female 3-pin, to power it from my fan controller, and just turn it to max in the bios. I have a lampoon 50w per channel fan controller. Would this work? If not, is there a better way?

  1. If you connect the cpu cooler ( your water cooler) fan into the fan controller, you may get problem because the PC can't find the cooler fan on MB during boot, then the PC can't boot. And if your MB has the option to disable in the BIOS like warning cpu fan failure and you will be OK.

    Hi, and thanks for your reply. The pump has a molex and a four pin CPU fan connecter. So I can power it from the fan controller and still plug it in to the motherboard. I guess I was more worried about powering a 12v pump from my 3pin fan controller.

    You will be fine because the controller can output up to 50W per channel, and the pump will draw 24W.
