3pin on 4pin fan header p8z77 I-deluxe

[wotevajjjj]

Hi
I connected my 3pin fans to the 4 pin header on the motherboard, ofcourse everything works, but it works at max speed now and I can't set it to a lower speed
I know you're all going to tell me to get a molex to 7v adapter or similar, but then I'd need to add a cable and I want to keep the pc as clean as possible.

On other boards I used, there was an option to set it to 3pin or 4 pin, but this one doesn't seem to have that option.
Any help ?

get a molex to 7v adapter or similar

there's your solution.
when done properly it looks cleaner than a fan plugged into your motherboard anyway

Yes but I'd have to put an extra cable in, just to run a fan. With a Prodigy, any cable left in the box is a good cable

completely forgot about those

I have similar ones here. But it doesn't solve the problem, it's just bypassing the problem

I remember reading somewhere that if using a 3-pin power connector with a 4-pin fan header, the fan will always be on, there is no fan control so you do have to use a speed reducer in order to slow it down.

There's a guy on some other forums (with a name I believe taken from Stargate SG-1) that produces converter circuits that allows you to connect 3-pin fans to 4-pin connectors and run them as if they were PWM fans.
Sounds sorta like what you want.
