Antec Kuhler 950 want to adjust fan speed without the softare provided

s8n · Aug 20, 2014

hi OC members , im trying to do some troubleshooting atm and i want to pull the USB cable that goes to my motherboard for the Antec Kuhler 950.

also i need to be able to adjust the Kuhler fans to my liking , there is software that comes with the Kuhler but you need it connected to USB to control it.

so yeah i need some other way of adjusting the fan speed

Run the fans straight off the motherboard CPU_FAN header.

hi ATM............

i have tried both CPU_FAN and CHA_FAN1 and they behave the same

also ive been fooling around with Speedfan the last hour and it reports my CPU as -60 C

in HWMonitor the CPU temp is fine

wacky stuff

Can you post your full system specs?

s8n · Aug 20, 2014

roger that , btw the CPU is OC to 4.5Ghz

its a PWM vs Voltage control issue
Are the Antec fans 3 or 4 pins?

s8n · Aug 20, 2014

hi Rollie.............they are 3 Pin

Did you try controlling it with Fan Xpert?
It's possible that your motherboard simply won't vary voltage for the fans plugged into it.

i didnt but i just tried it and it wont budge past 800 RPM

It's possible that your motherboard simply won't vary voltage for the fans plugged into it.

i definitely can hit high RPM but i have to use the software that came with the Antec and have the USB connected to the motherboard.

Well if your board's 3pin fan headers do not adjust fan speeds, and you don't want to use the software that came with the kuhler along with the USB to the mobo, then the only option left to you would be a fan controller.

This will allow you to manually set the fan speeds to your liking.

+1 for a rheostat type fan controller. Sunbeam rheobus extreme is a good one. Gives you and adjustment range from 0 to full speed. Some people object to the bright blue light knobs.

You do know there's an LED Mod right?

Thanks for the info but they really don't bother me since I don't sleep in the same room with the computer.

Well it's there for you (and the OP) just incase. I don't have the pc in my bedroom either, but it helped me dim the brightness. You're right tho, dang LED's are bright as all heck!

They're night lights on steroids.

The question is the third wire... is it a true Tach?
Does it report RPM when plugged into the MB header?
Or is it actually a PWM Control lead, but Antec couldn't be bothered to follow standard pin layout for their "build-in" fan controller.
Aspecially since Antec claims these are PWM fans

To know for sure, would need a molex to fan adapter. If the fan then runs at full speed, the 3th wire is NOT a tach wire
