Need some help changing fans on kuhler 920

post #1 of 5
Thread Starter 
I dont need help how to screw the fans in.

I want to change the stock fans with 2 Delta 120 x 38mm High Speed PWM Fan - 192.96 CFM AFC1212DE.

They use alot more power then the stock fans. How do i go about hooking them up to power? Im guessing i cant plug them into the mobo for power as there
Rated Voltage:
12 V DC at 3.0 A

Do i just plug the y cable for power into a 4 pin? Will the PWM feature, chillcontrolv program still be able to control the speed of the fans?

Looking for some directions and help before i purchase anything so i don't waste my money or blow my mobo LOL...


Thankyou,
Blood

Yea i have a fan that will overdraw and blow the header, so what i did was put the 12v wires to a molex plug and the rest of the wires going to the PWM header.

Plug those into the power supply like iCrap said. And then plug the PWM wire into the PWM pin on the mobo. Youll still have PWM, but those fans will most likely blow the fan header circuit from their current draw. I have some fans at home I would never plug into a mobo. They draw upwards of 2 amps. They draw so much, they have a slow start feature built into the fan motor.

So your saying even by plugging them into mobo for power, having the pwm plugged in will blow the circuit? Is there a workaround? would i just have to have them on a fan controller?

As the two gentlemen stated above, power the fans with your Power Supply (4-pin molex), then plug the PWM and RPM into the CPU fan header to control fan speed.

Here's the power cable to use.
