Can I adjust cpu fan speed with my Asus P8P67 ?

post #1 of 10
Thread Starter 
I just replaced my 120mm cpu noctua fan with the intel fan/heatsink that came with the cpu. The intel fan is a little noisy half the time, even when not running any programs, it makes a annoying sound kinda like a muffled whistle very hard to describe. If I'm not running any programs is it normal for the cpu fan fluctuate ? it's got to be fluctuating cause sometimes I hear it sometimes I don't.

Anyway I went into bios and it seems like it's running at 1400 rpms is that normal ?

I enabled the silent option and I'm at the desktop I can still hear a whistle. I tried the manual option instead at running 100% duty cycle I put 80% I can still hear it. How come when I change settings it's not taking effect ? thanks

By the way the fan hooks up to mobo with a 4pin connector, aren't 4pin fan connectors controllable ? I thought it was the 3pin fans connectors that were the ones not controllable

You replaced the Noctua cooler with the stock Intel cooler?

Did you try installing Fan Xpert from Asus or Speedfan to see if it will control your cpu fan? Why did you replace your noctua cooler with your stock intel cooler like Paradigm84 said?

For money and I'm not going to be OC'ing/gaming anymore. Also wanted to return my rig to a more normal retail configuration.

Anyway what program is there that I can monitor the cpu fan rpm in windows ?

Hi Subzero11, I helped you before about your 300R questions.

If your Asus board works like mine the CHA_FAN 4-pin controls both 4-pin and the 3-pin fans by DC.

The CPU FAN 4-pin is a PWM header that controls only 4-pin fans.

The PWR_FAN 3-pin runs always at full blast.
I'm not sure about the CHA_FAN 3-pin if it can control or not the fan speed by DC.

In my board the silent and the standard profiles use about the same fan curve.
If the cpu fan is loud with the standard fan profile it will be loud even at the silent profile.

The manual profile lets change the fan curve but decreasing the fan speed could also give you worse temps.

From my experience with the stock coolers they aren't loud while the processor is idling or running under common program tasks.
They could be annoying under some heavy gaming.

I believe that 1400 rpm is normal for the stock cooler fan with the processor idling.

Look this picture about a I7 3770K with the stock cooler.
The CPU Fan is close to 1400 rpm at CPU TCase 37 C.



Please can you post pictures with your FAN Xpert?
Check also the core temps using the HWMonitor or the RealTemp.

These are pictures with my FAN Xpert using the Hyper 212.
I don't know about your FAN Xpert options but I can also test the CPU FAN speed.

I'm getting messing with this stuff. I installed Asus fan xpert 2. No matter what I change in the bios for cpu fan or fan chassis it makes no diff. Fan xpert still shows same fan speeds no matter what I do in bios. I think I'm going to just get a new heatsink/fan for cpu. Nothing special with no extra mounting gear. Just something that attaches to mobo like the intel heatsink/fan does and that it's quiet. How many mm is the fan from intel do you think it is ? 80mm maybe ?

What's odd is that the fan makes that's particular annoying sound at diff rpms seems like when the cpu fan runs at the average 1200-1300 rpm it don't do it. It either does it at lower rpms or higher. Shouldn't it make it only pretty much at higher rpms ?


I've not posted pictures in such a long time I forgot how. Could you refresh me real quick on how to do it ? thanks man


Update: Not sure but it maybe working. I used manual settings and put the chassis and cpu fan at 60% duty cycle. Wait and see.

Realtemps is giving me temps between 35-40 for the 4 cores that's not to bad at idle right ?

The Windows 7 has a tool called Snipping Tool to capture screen shots (Start / All Programs / Accessories / Snipping tool).

Capture and save the image then upload it using the icon called Image.

I'm not sure but this should be the stock fan:

Heatsink/Fan: Intel Stock LGA 1155 i3/i5/i7



Rated speed: 2500RPM
Air flow: 25.9CFM
Noise: 18-24dBA
Dimensions(LxWxH): 89x60x37mm

These temps are fine.

Did you change the max duty cycle in the bios to 60%?

Speedfan might be possible to monitor the cpu fan rpm and I use Speccy to monitor my AMD stock cpu fan.

edsai asked:

Yes I changed both chassis and cpu fan to 60% max duty cycle. It's not doing the sound right now. But when I check with fan xpert2 the rpms are the same as usual, just like when it's set at 100% duty cycle o_O. I'm at work right now so I'll set up a pic of 100% and then 60%. So stay tuned. Whats odd at 100% it runs about 1300 rpms at 60% duty cycle it still runs at 1300rpms, how is this possible ? Am I suppose to disable Q Fan option in thebios or keep it enabled ? By the way when I do change the settings the only one I change is the duty cycle % I don't change any other settings, this is with the manual option enabled of coarse. Just thought I'd tell you that.

Is it possible that the fan just needed some break in period ? By the way that pic of the stock intel fan you got there is the one I have.

Actually the CPU Fan will run between min 20% fan power and max 60% fan power according to the CPU Temp.
I believe that the Fan Xpert will show the new fan curve in the User profile.

Disabling the Q-Fan will will make the fan run at max speed.

I found the stock intel fan picture and his specifications from a ebay seller.
