CPU fan speed on high constantly

The CPU fan on my i7 920 runs only at max speed. If i do clear cmos, the fans go back to normal but after restarting the comp, the fans go back up to max speed. How can I fix this? I am using MSI X58 Platinum with bios 1.3.

Hi, please provide a little more information:
1) Is your CPU Fan attached to the 4-Pin CPUFan-PWM-Header of the board?
2) Are you using a 4-Pin-PWM Fan? How many wires does it have?
3) What are your SmartFan Settings in the H/W Monitor Section of the BIOS Setup?
4) Do you have Dual Core Center installed on your system or any other tool that may be able to have an influence on the system's fan speed?
5) Please download Core Temp or Real Temp to check your CPU's Core Temperatures while the system is IDLE and when it is under full load. If the problem is not the fan, it's connection to the board or a BIOS Setting, your fan may simply be forced to run on full speed because the CPU is running to hot.

CPU Fan speed constantly running at 5000-5500rpms!

I have Cool-N-Quiet enabled in BIOS, AMD64 driver loaded and Power Management set to Minimal.
I know the Cool-n-Quiet is working because when I load CoreCenter it shows the CPU speed at 801Mhz.
However, my CPU Fan speed is always around 5000-5500rpms! My CPU temp is normally around 42C.
I can lower the fan speed manually to 2000rpm or so but as soon as I turn Cool-n-Quiet back on the fan speed jumps to 5000-5500.
Anyone know what could be causing this and how to fix it?

[Solved] Asus L1366 mobo, cpu fan speed control

Hi, everyone,
I finally have this new core i7 system, to replace my old AMD athlonx2. I have one question about the CPU fan speed control.
I remember that in my old system, the cpu fan speed control works out of box, no configuration is needed.
But when I install arch 64 on this new i7 system, the cpu fan is running at its maximum speed constantly while the CPU temperature is modestly low. I know there is a wiki teaching how to do it.
However, I am just curious why it doens't work out of box any more? Does CPU fan control work for you guys out of box normally? especially the new Core i7 cpu users?
Please let me know, really appreciated it.
Thanks a lot.
Update: the issue is solved, see my last post, the solution is blacklisting: asus_atk0110, instead use w83667hg.
Cheers.

First off, it would be useful to know what the sensors-detect script actually reports.
Okay. How fan control works on Linux: First, navigate to /sys/class/hwmon
Each of these folders, i.e. hwmon0, stands for a sensors monitor / fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
Examples:
pwm1_enable shows if OS-level fan control is enabled (1) or disabled and in BIOS control (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
temp1_input interfaces can appeare too, if some of the chips have temperature sensors located somewhere. I *think* lm_sensors places the core temperatures it reads from CPU (the coretemp-isa-000X thingies) in one of the hwmon-folders too.
There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector, and all in the same hwmonN are managed by the same IC on your mainboard.
Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your CPU shuts down.
(If you see something likein0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)
If one of those interfaces can do something, OS-level fan control does work, if none of those folders contain a working pwm interface, fan control seems to be unavailable.
Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.
I don't know what you are using to control fan speed, there are many applications that use these interfaces, i.e. GNOME or KDE power managers, so I'm not sure what is happening:
IF: Windows 7 enables OS-level fan control and sets it the RPM to those you observed and you have nothing that provides fan control in Arch and so fan control stays at BIOS-level, which might also read out a different sensor / the same sensor differently or it might be more conservative in setting fan speeds altogether;
OR: You have something that provides fan control installed in Arch and it reads out a the wrong value supplied by lm_sensors and thus sets a higher fan speed.
Anyway, possible solutions I can think of:
Find out if you have some kind of fan control software and what it does. For example, I use the fancontrol daemon, I can't help you if you use something else.
The wiki mentions how to assign a fan speed to a certain temperature sensors. You might assign it to a different one. For example, there are no sensor chips on the mainboard of my EEE (no temp1 etc.) so I assigned the fan speed to the temperature reported by the BIOS via ACPI (those are in /sys/class/thermal, also no "device" subfolder on EEEs):
FCTEMPS=/sys/class/hwmon/hwmon0/pwm1=/sys/class/thermal/thermal_zone0/temp
You could also change the MINTEMP/MAXTEMP values to one higher than those you actually want to compensate for the effect of lm_sensors reporting temperatures that are too high.
It is currently not possible for a mortal user to change the coretemps lm_sensors reads, see this post, last paragraph.
There is a configuration file, /etc/sensors3.conf, you can change sensor names and adjust offsets here, but only for the monitoring chips and their sensors that are on the mainboard.

How to reduce cpu fan speed just by hardware?

Hi,
I have a K8N Neo4-F, AMD3200+ and "arctic cooling freezer 64 pro" as cpu fan. The rpm range of this fan is from 300 to 2200. I use "cool n' quiet" and "Smart CPU Fan Target with 40°C" as bios setting. When the cpu is idle ( ... just doing some typing or so on ...) it has a temperature of 32°C and the fan has ~950 RPM.
I think the fan speed is to high for this cpu load (< 5% and 1000Mhz CPU Clock). My expectation in this szenario is to have the cpu fan speed near the lower bound (300 rpm), but I don't know how to manage this (with just bios settings) ... any hints?
Thanks a lot ...

My point was you did what D.O.T. is supposed to do without using it.
Of course it's point is to auto-overclock the system to whichever degree it's set at. The problems come in because a lot of the settings it uses aren't always compatable with a lot hardware combinations. That's why it's best to come up with your own OC settings that are stable with your parts.
It's just like how the Nvidia/ATI speedup option seems like a good idea, but works poorly in practice.
Both are more useful to the marketing dept. in having more "why tech" features available to print on the outside of the retail box than they are to the end user.

CPU fan speed on P45 Neo3FR

I just installed Coolermaster Gemini iis cpu cooler on my system. From the HW monitor, I found that the max fan speed was only 1867 rpm. A similar reading was found on the reading of DualCorecenter utility. I have put the CPU fan speed in the bios to maximum but no change. The support center of coolermaster has confirm that the fan is able to run up to 2000 rpm.
Does anyone have a suggestion?
My system is
mb: P45 Neo3FR pcb 1.0
bios 1.8
CPU : E8200
PSU : Antec pure power 430

I tried the options in the smartfan, but no response. The fan speed did not change. Actually, my problem was the cpu temperature is about 1-2 degrees higher than the stock cooling. So, I took of the fan, cleaned both CPU and cooler, applied the correct amount of thermal paste following your suggestion. Now, the CPU temperature is about 40 to 41 C during idle compare to 43 to 44 using stock cooler. The fan speed has increased to 1910 rpm.
I just wonder that the fan speed may not properly regulated by the bios. Do you think it is necessary to tell MSI support?

760GMA-P34 FX CPU Fan Speed Issue

Hi all.
I got my MSI motherboard set up with a Cooler Master Hyper 212+ heatsink. I set the target smart fan temperature in the BIOS to 50* and the minimum fan speed to 25%. I boot into Windows and the fan is around 600RPM. I apply load to the CPU and watch the temps smash through the 50* barrier and the CPU fan speed stays the same.
Thinking there's a little overhead and maybe I set the target temp too high, I tried setting it to 40*. Same deal, it gets up to around 55* before I shut down the CPU benchmark.
What gives? I thought you set the target smart fan CPU temp and the fan ramps up after that temp? I tried setting the default fan speed to 12.5 and 50% just to make sure the PWM is actually working and it is, because the fan speeds differ for each one of those settings.

The same problem!And I'm all tried everything and finally gave up
I moved the 4 pin connector with cooler to sysFAN2 and control rpm with SpeedFan
How are you able to use Speedfan with the 760GMA-P34(FX)? As far as I can tell, Speedfan doesn't recognize the Fintek IO chipset on the board. Even on the latest beta it's unrecognized.
One other oddity is I noticed that apparently the BIOS ramps up the Sysfan2 fans' speed slowly when the case gets hot, but the same isn't true for the (PWM) fans on Sysfan1, they stay at the 50% I set it to in the BIOS. I wonder if PWM actually doesn't work well for the Sysfan headers on this board.
I think I'm going to have to get a speed fan controller as this board is coming up a bit short here.

MSI Max 2 BFIR; Problems with CPU Fan speed in PC Alert!

servus...
First of all, I have Bios version 1.3 from the .de support Page.
I don´t know, why .com.tw doesn´t have this version.
But here´s my problem:
PC Alert doesn´t show a CPU-fan speed!
The northbidge fan shows the fan speed roundabout 5000.
In BIOS CPU Fan ~2500
PC ALert versions:
4.005
4.006
Any ideas?
Thanks

Thank You for the reply,
Before the latest update to PCAlert4 it was working properly, I cross checked the reported info. to that of Sandra, MBM, and in the bios.
Also the temps are only swapped between the system temp. and the CPU temp., other than that they are correct.
Thanks,
John

CPU fan speed problem -- similar to one already posted

Core i7 290
6GB SuperTalent DDR3 RAM 1333 (3x2GB)
BFG GeForce GTX 275 OC
2 120mm case fans (front/back)
Thermaltake CL-P0533 CPU cooler
Vista Home Premium 64-bit
MSI x58 Pro MoBo w/BIOS v.8.3
PCP&C Silencer 750 watt Power Supply
500GB Seagate Barracuda HDD
Yeah, I know that all that info probably isn't that necessary.
Problem: I have a Thermaltake cl-p0533 for my core i7 920. My fan runs 6000+ RPM all the time. I've tried using the overclock center, greenpower center, and the BIOS smart fan thing. In BIOS, I tried setting it to 25% idle and 50c target temp range. No dice. I've tried using speedfan and all that I got was the speed knocked down about 300-500rpm for a bit. My CPU idles at about 33c (according to speedfan and OC center). The CPU fan speed is supposed to be able to be controlled. The noise is really annoying. Any help would be most appreciated.

Core i7 290
First, I meant 920 (I must be dyslexic or something)
Yes, the CPU fan is connected to the CPU fan power connector (according to the mobo manual). I've set SpeedFan for the same as I had my BIOS settings. I've since changed them to lower temps. I've tried SpeedFan with and without using the SmartFan feature in the BIOS enabled. My Two case fans are super quiet, so I don't use any regulation for them. So my SpeedFan settings look like this:
Speed 1 - minimum value = 25% maximum value = 100% auto variated
Temp 1 - Desired = 42c warning = 50c
Cores 0-7 = same as Temps 1 settings
I've also disabled the other temperatures for monitoring and fan control
As for the number of wires for the cooler fan, there are 4 going to the mobo.
I don't really know much about add-on fan controller parts. If that's the route I end up needing to go, any recommendations?

Z77A-G45- CPU fan speed problem

Hi all, new to this forum and MSI Motherboards.
i have a problem with my CPU fan speed when i plug any fan and water cooler fan into the CPU 4pin they all run at 2000+ rpm, but when i use the fan 1 or fan 2 --4 pin it runs at a slower speed of 1400rpm, am i missing something in bios, i have 2.5 version of bios, would be greatfull for any help....

Should be able to adjust in the section below or with control center.

MSI H81M-P33 Cpu Fan Speed Problem! Urgent

Hi. Bought a H81M-P33 board and got a problem.
I can´t increase my CPU fan Speed to maxium RPM . Tried to use Command Center and Board Bios without any sucess.
This leads to my cpu (i5 4670) getting hot with stock cooler. When I´m encoding a video it reaches 85º. The best solution I had was to connect CPU Fan to Chassis Fan slot on the motherboard and it increased speed, but still it doesn´t increase past a certain value.
What can I do to solve this problem? Tried everything without any luck. The board doesn´t handle CPU fan speed + temperatura increase well. Is not normal to have a CPU stock volts getting hot.
Thanks

I know that for sure XFM. The thing is that the board isn´t increasing CPU fan speed as it should. Ofc a better cooler would do the job, but even with stock cooler it can be cooler. The problem is that the fan is always in slow mode :|

Motherboard or CoreCenter controls CPU Fan speed?

I have the 865G Neo2-PLS board running 3.6 bios.
I'm not so sure I want to use CoreCenter; but I liked the way it adjusted the CPU fan speed, based upon the temperature reading. Or was it the MB itself doing the adjusting? I know the CPU has a feature which throttles down activity if it gets too hot, but I'm curious what controls that CPU fan automatically. Thanks.

Hi
I must say that am very happy with Corecenter in automode!
I have it on my autostart in the program list! It kicks in automatic and controls the rpm of the CPU fan ( 1300 - 2200rpm) depending how much I push it!
I have never had any problems with it...........Use liveupdate to get version 1.6.2.0.
I must say that zalman have saved my day......its silent.....hmmmmm silent...

GS70 Stealth Pro - a way to manually set fan speeds to HIGH?

Hi ...
This regards a G70 Stealth Pro (970m version) ...
Is there some way I can manually set the fan speeds to "high" before gaming?
The default fan curve/profile is working pretty good but I think temps during gaming would be even better if I could set them to near maximum for the length of time while gaming.
Thanks for any information ...
Joel

Quote from: panni on 16-November-14, 02:39:28
I didn't try it with the GS70, but I've used HWiNFO32 for my Alienware M15X in the past to create my own fan curve:
Thanks for that ... I'll certainly check out hwinfo32 ...
Otherwise, I don't have any throttling issues with the 970m Stealth variant ... no game ever breaks 85C (yet) ... Metro games, Skyrim ... 3DMark ... 85C is the hottest I've seen.
I'd just like to set fans to MAX to keep temps even lower ... since I use headphones, noise is never an issue.
Thanks again and best...

CPU Fan Speed always LOW? -- K8N NEO4 Platinum SLI

I'm wondering if anyone can help me out. My CPU fan speed is consistently around 850 RPM, both at idle and under full load. This is shown in the BIOS, with Corecenter, Everest, and Speedfan. I have Cool n Quiet disabled in the BIOS, CPU Fan Target in BIOS set to 40 deg (have had it at 60 as well), and Windows Power Scheme set to Minimal Power Management. I've even tried enabling Cool n Quiet to see if it actually did anything...but fan speed is still the same.
It seems everyone else has CPU fan speeds in the thousands rpms. Mine never changes, is always around 850.
My CPU temps vary between 37C idle and 48 load when my ambient room temps are around 75 deg.
What's up with my CPU fan?
EDIT: Speedfan doesn't seem to work for adjusting anything. It only shows my CPU (fan2) and NB (fan3) fan speed, but adjusting the percentages has no effect.
My Config
MSI K8N Neo4 Plat SLI
Athlon64 3200+ 939 Venice
1GB (512MBx2) PC3200 DDR OCZ Value Series 2.5-4-4-7

Try setting cpu fan speed to max to access this open corecentre & click on logo.
should give:-
Select user mode & set Fan to max. This info is held in the corecentre chip & is the only way to access it .
Only keep corecentre installed for this function
hope this helps.

CPU FAN Speed & Voltages Question?

I have an MSI KT4 Ultra MB with a retail AMD XP2400 Processor which came with a Fan & Heatsink.
1. My Temps are fine, gen However my CPU Fan speed varies & I get the following speeds indicated at various times - 4141, 4167, 4116, 4193. Is this OK? I do not believe my Fan speed can be controlled by S/W so I was wonsering why this oocurs?
2.
Any advice or comments would be much appreciated! I am a compulsive worrier regarding my PC.
Cheers

1. post your PSU brand and amps
2. get another hsf, these delivered with cpu are not good.
