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.

    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.

    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?

  • 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 :|

  • 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

    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.

  • P67A-G45 (B3) fan speed keep dropping to 0 rpm

    I just got this motherboard (P67A-G45 (B3)) for a month. Just only today, I notice the CPU fan speed being detect keep on going to 0 rpm every 10-15 secs. It goes to 1800 rpm then after like 10 secs, you can it become 0 just for a second. Then it goes back to 1800 rpm.
    When I turn view this under control center II in windows 7, it also shows this symptom and alarm get triggered.
    I did not do any over clocking. I am using Cooler Master Hyper N520 heatsink. The fan for this heatsink only have 3 pin which I doubt is the reason for the board to detect 0 rpm. Anyone having similar problem with this motherboard or HSF?

    My parts for 2 units of 3-pin fan cable arrived. After some modding, I connected it to replace the existing 3-pin Y-cable. Partially works. When I check in the BIOS level, I can see the speed drop occasionally to around 500rpm. However, when I boot up to windows and using speedfan, below is what I get.
    Still getting speed drop to around 500rpm but it happen less frequent and at least not 0 rpm. I am okay with this. As I don't have another motherboard to test. Plus I really do not want to take out the HSF again as it is a lot of work. Need to take out the whole motherboard for that.
    edit:
    I switch between fan1 and fan2. Take note fan2 is sysfan1 on the motherboard. I plug the HSF cable into fan2 and for fan1 I plug the PSU fan. So this time I see fan2 speed drop to 500rpm every 8 minutes.
    So conclusion, problem is with the HSF. Cable? Or the Fans? And why does changing the cable fixes the problem "partially"?

  • Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

    When did the fan problem start?
    After I replaced the mother board on the computer.
    Why did I replace the mother board?
    Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
    What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
    1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
    2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
    3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
    4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500

  • 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...

  • 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?

  • 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.

  • CPU Fan Speed: How to Adjust?

    Hello,
    My 975X has what I believe is an issue with the SATA controller, which prevented reliable SATA (hard drive) operation.   I went to the local Fry's and replaced it with an ASUS P5Q-Deluxe.  One thing noticed is that ASUS has a software utility (AI Suite) to control CPU fan speed.  On my 975X, the CPU fan ran "full out".    When I looked I didn't see a utility to reduce fan speed:   Fuzzy Logic and Corecell didn't seem to adjust the fan speed, but could monitor it.   Was there a utility to the control the CPU fan speed that I overlooked?     If so..too bad..I could've had quieter operation.   If not, then I presume MSI motherboards now have a utility to adjust the fan speed so that it scales with CPU temperature, and thus reducing noise?   I'd like to know as I'm sure I will buy another MSI motherboard at somepoint.   Thx.
    Scott

    Quote
    You replaced it? Or do you still have one?
    I still have it, but the SATA controller needs to be repaired; new disks, cables, OS installs, and power supply failed to fix the problem so has to be MB.    While I can RMA the board, it is about 3 yrs old so MSI wants $35; not sure it is worth it.   Comments?
    Generally I've been happy with MSI as I've used their boards for 6+ yrs, but I also really like my ASUS boards.

  • 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.

    Quote from: nenchy80 on 11-September-13, 20:50:39
    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. 

  • 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.

  • 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

    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.

  • [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.
