Core Center/CPU Fan Speed Reduction

My CPU Fan Speed does not cut back after boot up. If I go to the Cool'N'Quiet dialogue in Core Center, click the Cool'N'Quiet button and then apply, it reacts. The fan speed reduces, and it regulates itself. I have the latest Bios for everything, Cool'N'Quiet is enabled in the Bios, and the power management is set to minimal. The speed cuts back to 800mhz no problem.
CPU: AMD 64 2800
MB: MSI K8T NEO FIS2R
RAM: 2 x 256mb OCZ EL
Video Card: Sapphire 9800Pro
HDD: 2 x Seagate 7200.7 SATA 80GB as RAID 0, 1 x Maxtor Diamond Max Plus 40GB for back ups
Soundcard: Audigy 2

I too have had problems getting this to work properly. I tried a number of different combinations. This is what I found.
The most stable was to disable CnQ and enable the NB and CPU temp targetting bios options, setting both target temps to 40C, and reducing tolerance to 2C.
The big benefit of this (apart from the stability bit) was that no additional software has to be loaded or run.
I also tried CnQ (with the targetted temp stuff disabled). This worked better in the snese that dropping the CPU voltage and mult cools and quietens the CPU even further. But it suffers (on my system - Athlon64 3000+ Clawhammer) from three crucial problems:
1. It varies NB fan speed based on CPU temp, not NB temp
2. CnQ does not restore Max performance CPU state (i.e Mult = 10 and Vcore = 1.5) when you start up an app that uses a genuine 100% of CPU
3. CnQ reduced the normal Vcore slighltly and made it vary more, causing system instability)
4. You needed CoreCenter running, and its buggy as hell
I tied Speedfan, and it worked well. It is more controllable than the bios targeting rout. In the end I decided that the bios rout was better as it didn't depend on any application running - it makes the colling part of the hardware and I think that's right.

CPU fan speed problem -- similar to one already posted

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?

CPU Fan speed

Hi everybody
My question is: what is the range (min and max rpm) in which cpu fan speed should stay?
I have an Athlon64 3000 with retail fan.
Thanks for your help

I've read here that some of the earliest versions of CC did not have this bug, but I can not remember at the moment what version that was.
If you set the fan control to "user mode", change the CPU Fan to "low speed" hit apply, then change the fan control back to "cool'n'quiet" you should find that corecenter will start up at low fan speed. corecenter seems to set the fan at whatever was last set in "user mode" on startup which is max speed by default.
Might save you a few seconds every boot up...

DualCore Center CPU Fan at 0 rpm randomly ?

Hello everyone.
I recently got a new system with an MSI P965 Platinum motherboard, it's the first time I use MSI, before this I only had Soyo, Asus or Gigabyte motherboards.
System specs:
-MSI P965 Platinum
-Core 2 Duo E6400 @ 2.13 Ghz (stock speed, nothing overclocked)
-(2x) 1Gb OCZ 667 Mhz DDR2 RAM
-Sapphire ATI Radeon X1950XT 256MB GDDR3 PCI-E
-500W Powercooler PSU (+3.3v_28a,+5v_34a,+12v1_20a,+12v2_17a)
-Western Digital SATA Hard Drives WD3200KS, WD2500KS & WD2000JD
-Pioneer DVR-109 & DVD-120
-WinXP Pro SP2
My problem is that DualCore Center ocassionally pops and triggers an alarm indicating that the CPU fan speed is 0 rpm, it takes a couple of seconds and goes back to ~1950rpm and then again to 0rpm. At first this happened a couple of times while playing heavy 3D games, but I thought it might have been something related to the games so I just close DualCore Center before playing. I assume this because I've seen this kind of behavior on Asus PC Probe software in the past.
However I just saw it pop while browsing the internet and it kept going up and down so I had to close it or mute the sound.
I can see the cpu fan since the case is open and it looks ok, although I was thinking if the fan is indeed loosing power in 2 second intervals, I may not be able to notice it with my eyes.
CPU temp is around 32~34 C, System temp is along those lines as well. I think when CPU load is 100% the worst temp that I've gotten was maybe 40~42 C, but I don't think it ever got above those values.
I believe DualCore center version is 2.0, I had to download it from the MSI web site because the version that came with the motherboard Driver CD did not work.
Any ideas, thoughts or comments will be highly appreciated.
Thank you.

Don't use Dual Core Center and you will not have this kind of problem.
Whenever I use Dual Core center, alarms go off, stuff starts blinking, the system restarts or it freezes, hangs, causes strange error messages or suddenly decides that my system doesn't meet the requirements to run it at all. On very beautiful and sunny days only it seems to work fine....
As long as I stay away from that strange tool everything is fine and stable.
Dual Core Center ist not the best tool ever written and considering the fact that it causes problems on many systems, the best idea is usually to delete it and never touch it again.
What do you need it for anyway?

CPU Temp and CPU Fan Speed

I am having a strange problem . One time I will boot the PC and CPU temp is 43 and CPU fan speed is 1308 rpm in Core Center. I do a restart system and the CPU temp is 32 to 36 and CPU fan speed 3308. Not sure if I should trust Core Center . Bios shows CPU temp 48 and fan speed of 3328. I have been reading here that there are a bunch of threads containing some kind of problem with CPU temp or fan speed. My Bios is 1.4. If anbody can give me some ideas that would be great.

Open CoreCenter on deshtop. Click where it says CoreCenter. Click Cool&Quite button. Then Click apply. This drops the fan speed back into the 1400 range and the temp will rise back to the 40s.

K8N Neo4 Setup - Issues Adjusting CPU Fan Speed - Alarm Going Off

Building this PC for a friend, and I just got it to post. Everything seems to be running stable, only when I get into the CoreCenter, the CPU Fan alarm is going off and the speed is flashing red. It is currently running at about 820 RPM, but the CPU temp is sitting at 37'C and the sys temp is 32'C. Is this too hot, is the fan speed way too low, I'm somewhat new to this. I set it to Cool'n'Quiet and it still does it, I disable Cool'n'Quiet and try to increase CPU fan speed manually, and it won't increase. Any input would be greatly appreciated. The rig is setup as follows;
MSI K8N Neo4
AMD 64 3000+
Kingston 512MB DDR400
80GB Seagate ATA
nVidia GeForce 6600GT 128MB
Antec NeoPower 480W

You can adjust the alarm level by clicking the little red arrow(Hardware monitor option) on the right side of Core Center, move the slider for CPU Fan Speed Alarm to the left(set it to 500-600rpm), and click OK.
Now you shouldn't get alarms any more.
The fan speed and temperatures you report are very similar to what I see on my system at idle. The fan shold begin to run faster if the system is under load for some time.

[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.

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 :|

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?

CPU fan speed = overheating. (Fixed)

Well, where to start.
For the past week I've been having problems with my system, turned out it was overheating because the CPU fan speed was very low, once I opened the Core Cell application it speeded up the fan and all is well (but I don't like having to run a bunch of applications to keep the system running the way it should be without. them and these applications don't start in safe mode.) I'm currently using BIOS version 3.30 and read "BIOS reported incorrect CPU temperature." but it does report the correct temperature, it is overheating because of the fan speed.
Does anyone know if updating to the current/latest version (3.60) will correct this problem with the CPU fan speed (it's only been hapenning after I updated to v3.30)
Motherboard: MSI 875P Neo-FISR
Thanks.
Edit: Fixed.

NovJoe,
That is a job by itself!
Everybody has different components on their systems. They buy cheap rams, case with insuficient power supply, lousy cooling, etc. and they are short on money like myself. How can I help them?? My general advise is buy top of the line components or buy a Dell if they don't want to research before they build a system. I know its hard to put out that much cash, I actually got my motherboard from a friend FREE! He had a lot of problems with it. I always had motherboards by Abit or SuperMicro Dual Processor and in the earlier years I had a Sun Microsystem SPARC 10 running Unix. I also get them FREE! They were prototypes before production lots of jumper wires. When I retired at age 47, five years ago I only work part time now when I need spending money like for Christmas and 10 different hobbies that my wife thinks is to much. Yes I wrote CHRISTMAS not Holiday. Grandkids, my wife spoil them all year, but we have to get in the spirit of Christmas she said. AHH HUMBUG! LOL! I need a couple of those new 300 GB SATA Maxtor drives with Command Queuing to get rid of my four 20 GB Maxtor and one 40 GB, I also got them free when I did a job for them 8 years ago and they are still working great. It will reduce my +12V load, increase my storage capacity and my hard disk speed. I had them on a Promise 66 PCI RAID controller card on my old SuperMicro Dual Processor motherboard.
If a person has a problem with a MSI 875P NEO-FIS2R and a decent setup, I will definetly give them advise if I can.

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

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...

Ultra 40 M2 core temperature and fan speed

Hi,
I'm using a Sun Ultra 40 M2 with two dual core AMD opterons 2218 running openSUSE 10.3. I have been trying to use lmsensors to monitor core temperature and fan speeds. It seems to be working and I have been able to use gkrellm as well.
At low load I get temperatures around 40C on all cores (as measured by k8temp-hwmon), and fan speeds of about 1500 (rpm?; as indicated by lm85-hwmon2/fan1 and lm85hwmon2/fan2; only two fans?). However, at full load all core temperatures go up to 70-75C (steady) and fan speeds increase up to 2500 (which does not seem to be the maximum speed of the fans, as they are much noisier at booting stages). I wonder if such an increase in temperature is normal and how can I setup the fans' speed, if at all possible.
Thanks,
Marcos.

I'm currently running dual 2222se chips, an fx3500, and a single samsung 15000 146gb with an idle temp of 40-42c. But, I've run into a problem. For some reason, when my system boots, the fans run through the BIOS checks, but after post, the fans stop entirely. I've gone into the BIOS and fiddled with a few of the settings, but haven't been able to rectify the problem. Is there a specific setting that I may need to change to get the fans to actually run after post?
I got this workstation used, so I was unable to get the tech support information I was looking for without paying an additional fee. So any help whatsoever would be MUCH appreciated.
ChinGimLeong, as far as your idle temp goes, that sounds about right for the setup that you're running. You may want to look into purchasing some thermal grease and cleaning your chips and totally reapplying the grease. Improper application can hinder the heat transfer, causing a bit of a high idle speed. But if you apply too much, you WILL fry your board and processors. Another thing that you may want to try would be adding an external ventilation source to help get a bit of faster airflow. I use an 8 inch desk fan, it adds a bit of extra noise, but noise is nothing when you're protecting your system.
Let me know what you think.
