High RPM CPU Fan

[ocrmp732]

Lately my cpu fan is running over 4000 rpm constantly even when idle just in the bios after shutdown.

I haven't made any changes to anything here the pc is completely stock and never fiddled with the fan settings they run on standard in the bios up until this point the fan was silent now it's just loud all the damn time.

The pc is 7 months old and as you can see by the hwmonitor it's running very cool I almost never run at 100F my normal temps are between 80-90F 99% of the time.

The circled you should select your chipset, as shown PWM 1 2 and 3 as Smart Fan IV and that should be manual PWM, and then you have to see which on start when says error on % change and hear which one is your CPU cooler.

I've done that but the only thing that is in that dropdown menu as your image shows is my hard drive, There are no other options.

Well seems that you're gonna have to "Fiddle" with settings in bios about Q-Fan, or change your CPU cooler, unless others have opinion. It may be bios/software bug, try to update bios.

Right now I'm running the most up to date bios software, Was thinking to take it off cpu fan connection and try it on Cha1.

Qfan I went thru every available profile and even ran it manually on bare minimum settings and still stays at 4k rpm's, Qfan atm is disabled I have system cooling in passive, cpu temp actually has gotten hotter, it was running 82F at 2100 rpm's ever since the fan increased to 4115 rpm's the temp is now 98F.

So I'm all out of guesses myself...

Till 150F temps should be fine. In Q-Fan try to

select manual and black line to bottom till 60*C~ and then raise.Try first DC mode and then PWM.
If that doesn't help im out of ideas :|

I'll try it but I should point out on my Qfan Control under CPU Fan I have no option for PWM/DC there's nothing there like that, Only CHA1 Fan has the PWM/DC option.

When I ran it under manual I had the line exactly as your picture showed, that was the bare min I could put it at and that did nothing on restart still stayed at 4115

Try optimize all.

This is what my Qfan looks like first pic is my cpu fan

Next is CHA 1

As you can see what I am talking about PWM is only on CHA 1, And it's probably cause my cpu fan connector is 4 pin but my fan is 3 pin, the 4th pin is exposed and from what I read that's for PWM control

Try optimize all.

I have multiple times does nothing at all, I posted on linux tech tips.

Thanks for the help though just mind boggling

So on Linux Tech Tips I had one reply that stated "It's probably an internal issue. A Shorted PWM Control Line or something similar"

I again unplugged the fan from the cpu fan connection on the mobo and then plugged it into the CHA1 connection and finally I was able to fully control the fan in QFAN whatever profile I picked the fan responded to however whenever I restart I get a fan error I imagine I get that because the fan isn't on the CPU fan connection anymore.

I also took another cpu fan out of another box I have here and connected it to the cpu fan connection and that fan also runs 4000 rpm's, In the box it came out of it was running 2400's, So starting to think maybe the cpu fan connection is the issue because I put it back in the original box and it was working normally.

I went thru my spare parts and found a 4 pin cpu fan though doesn't sit well on the heatsink but it showed me what I figured I cannot control the original 3 pin cpu fan that came with this pc via QFAN, I can control the 4 pin fan though so I rigged it in a way temporarily till my 212 evo comes where it's keeping the cpu between 95-102F constantly and only running at 650-850 RPM thru the silent settings.

 

[ocrmp732]

Well I have the spare 4 pin fan still working 3+ hours later it's bouncing between 1300-2500 rpm's no higher which is good, I was finally able to fix speedfan, Turns out I needed to repair and rebuild the WMI because msinfo wasn't populating once I fixed that speedfan now works.

However my chipset window looks way different then yours Robert, As you can see in the pic there is no PWM options on mine.

This is showing the spare fan I'm going to reconnect the fan that was giving me trouble shortly doing a full windows repair as it's found a lot of things wrong in my windows.

I took that picture from internet, thats why i asked your motherboard, well im glad you solved your issue , sorry if i somewhat "drag" you across this whole conversation.

IF you can use it via Q-Fan because SpeedFan is old af. and you're unable to control it via speedfan as i see.

It's alright.

Qfan is working for the spare fan I found I have been running it for little over 7 hours now never has it gone above 2500 rpms, Still trying to figure out what happened to the original fan because that fan works normally in another computer, Ive had it in a Dell box for for the same time frame 7 hours and it's been running between 1300-1800 rpms max and I just took it out 10 mins ago and put it back in the computer that it was running high on and it started up at 4092 rpms on boot so it's very puzzling why this is happening but similar fans run normally on here.
