P67A-UD3P: sys_fan/pwr_fan speed
« on: August 10, 2011, 04:56:19 pm »
Hi, I'm using a P67A-UD3P-B3, and I'm wondering if there's any way to control the fan speed of fans attached to any of the 3-pin fan headers on the board. It'd be nice to not have to listen to the drone of two 1400rpm fans when my system is already very close to room temperature. I've tried playing with speedfan but it doesn't seem to be able to change the speed of fans attached to sys_fan1 and pwr_fan1. I can control my cpu fan with it, but I don't need to do that as the bios does that for me just fine.

Is the board just plain unable to control those fan headers? The RPM data can be read from both the bios and windows, but there's little point to it if they spin at 100% 24/7.

Hi Patchu,

If your fans have a control, like button minimum, maximum and middle range, they can not be monitored by Speedfan.
Check ours speed with HWMonitor
http://www.cpuid.com/softwares/hwmonitor.html

Oherwise, go to Bios and check yours setting fan in PC Health Status.
Like CPU Smart Fan Control enabled for check Pulse Width Modulation (PWM).



If your fans are PWM and without button control, normally you could use SpeedFan.

If you have options of parameters such as FAN CONTROL in Bios like:
min
max

or any other parameter choices or or more options for the fan settings, it is possible that Spedfan can not monitored the fans.

Hi

To add to what Gloup_Gloup has already said in your situation I would suggest removing the fan control from the motherboard and adding a dedicated fan controller something similar to the one I use for my system that gives total control and feedback on tempertures, speeds, etc. It removers the load from the motherboard as well which can be good especially if any of your fans are heavy duty ones.

Thanks for the replies

@Dark Mantis
They're just basic 500~1400rpm 120mm 12V fans with 3-pin and 4-pin connectors. I don't really want to have to spend another £50 on a fancy fan controller just so I can slow them down from running at 100% all the time.

@Gloup_Gloup
Speedfan can only seemingly control my CPU fan and not my case fans, but it's reporting the speeds of them just fine. I'm not having trouble with that. My fans do not have any hardware controls with sliders or buttons or anything. CPU smart fan control is enabled and set to PWM, but as far as I'm aware, that is only relevant to my CPU fan and not the rest of the fan headers.



Is the P67A-UD3P simply unable to control power to the system fan headers despite them being 3-pin? n the bios it only reports the RPM of the fans, not giving any options to control them. The only control option seems to be for the CPU fan itself which is 4-pin. I've tried using the other 4-pin header on the motherboard for my akasa apache but the fan slows down and stops randomly when connected to it, even when the PC is under load.

The specific fans I'm using are:
Arctic Cooling F12 120mm PWM 3-pin (connected to pwr_fan header (3-pin))
Akasa Apache 120mm PWM 4-pin (connected to sys_fan1 header (3-pin))

You can get a much more basic controller for under £20 that will allow you to govern the speed of the fans.

I probably can, but it'd also take up space in my case and add extra cable clutter, so i'd rather exhaust my other options before I resort to that.
