Z87-GD65 CPU Fan speed control not working

As per the title, the fan speeds set from either the BIOS (E7845IMS.1B0) itself or from within Command Center don't make any difference to the sped of the fans on the CPU cooler.
The cooler is a Noctua NH-D14 with stock fans (non PWM)
Can anyone help?
I'm not sure if I've missed a BIOS option anywhere!

However, I removed the fans from the CPU headers and put them on system fan header, now the fan controls work - looks like the mobo is faulty :(
Not gonna RMA it though, it's pretty trivial
It's not faulty at all.
The CPU fan header is PWM only!
The obsolete Voltage Control method is not recommended for CPUs.
It's a recipe for failures.
All the modern motherboards require PWM control for the CPU fan.
So you should replace the CPU fan with a PWM one.

[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.

T430s fan noise and fan speed monitor not working?

Hi, I just bought this T430s from the outlet store. I noticed a rather loud fan noise and found out s lot of compalints about the T430 model. I guess the problem I have is not as severe as those T430 users (e.g. the noise may not be as loud), but I still want to monitor the fan speed. Here's my problem:
1. none of the third party software can show fan speed, they can only show the cpu temperature, such as speedfan and aida64.
2. I tried to download the fanspeedcontrol driver from lenovo, but after installing it, the task manager does not show that the fanspeedcontrol exe. is working.
I do not want to change the fan speed, but just want to monitor the speed so that I can have a better understanding of whats going on. Does anyone have the similar problem?
Thanks.

Hi Alan, (I know this conversation was from several months back),
I don't know the answer to your questions. It seems that your fan is operational, as far as its most basic functional requirement.
I don't have experience with any particular software programs or widgets that indicate fan speed, sorry.
Do you have any view, through software, of the CPU (and GPU?) sensed temperature? Those would be very good data to observe.
If it were either disconnected or non-functional, I assume that your computer would report a POST error right after power-on (and self test).
But I just wanted to suggest here that in an unfortunate possible scenario, consider if the thermal grease on the heat sink(s) was inadequate (or was missing), then the fan would be running higher than normal (probably always spinning at a high rate), and it won't be taking enough heat away from the processor(s), i.e. inadequate cooling.
Which could be corrected by a technician (or DIY). This is pure speculation, it is not a definite, at all.

Fan Speed Controll Z77

Just wondering if someone could help me, I am looking to buy a new motherboard based on the Z77 chipset (I am currently running a P67-G45), I know this is a very unusual question but does anyone know how many of the system fan headers on the Z77-GD55 and ZZ7-GD65 supports fan speed control. I am currently using a Corsair H80 with two Gentle Typhoon 1800rpm fans being speed controlled by the motherboard to 50%. Do at least 2 of the system fans support fan speed control other than the CPU fan header?

Z77A-GD65 CPU & SYS fan 1 & 2 support fan speed control (4 pin header for them) according to the manual. SYS fan 3 & 4 fan speed monitoring only. I did not check any of the other Z77 MBs. If you want to all you need to do is download the manuals and check them yourself.

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.

Z77 mpower cpu fan header "control" no longer working

CPU fan header now only works with 3 pin fans, 4 pin fans turn off when placed on header, do not turn on. I had been running a hub off of that port to a switch 8 port fan hub controlling all case fans and a pump. cable to header only had sensor and control, power was through molex, pump which was master only had same. I had hot swapping on, had added a HDD reported bad by raid in another tower in a hotswap drive tray (hot swap on in bios) was going to check it out in seatools. tower crashed on add. rebooted, when running seatools noticed temps way out of line 70-90c normal temps even under load 60c or less. noticed tower was quite, noticed no fans turning. booted to BIOS checked reported no RPM fans not spinning in health changed options, did not help thought hub may have died. powered down unplugged and plugged pump into cpu header. power back up fans running, but still high temps cpu header shows 0 rpm. shut down move pump to sysfan 1, reboot powers up pump on temps good. pump running at 100% speed had never seen it running like that on sysfan 1 even when told to. reboot try 4 pin fan in cpu tries to spin for jet a sec then nothing. reboot try 3 pin, fan powers up spins shows in pc health. reset to default, tried 4 pin no good, switched to older bios, rebooted no good, reset cmos no good…. any ideas forum wizards? I would really like to regain control so i can throttle fans/pump.
note bad HDD was pulled before swapping headers….

1) I find it strange it does not effect the other 4 pin headers do they just not use the control line despite it being there?
2) i do find it odd that prior to this running the pump directly on sysfan2 i could never get it to go to 100% only 50%, since this happened it stays at 100% on sysfan2
1) CPU_Fan has its own circuit.
http://www.swiftech.com/8-WayPWMsplitter.aspx
We generally recommend to use the “CPU_Fan” connector of the motherboard,because most motherboard manufacturers usually allow a greater range of adjustments on this particular connector.
2) probably the Voltage Contol is damaged too (if they get the max voltage (12V), they stay at 100%).

CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,
I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +60.0°C (crit = +100.0°C)
temp2: +59.0°C (crit = +100.0°C)
temp3: +66.0°C (crit = +100.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
Here is the main problem:
1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

The fan was bad. I had to replace the fan. However, I have not been able to figure out how to see fan speed in sensors.

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...

K9n Platinum fan speed control

Hi!
I have the following configuration:
-Motherboard: MSI K9N Platinum v1.1
-Bios: AMI v1.3
-CPU: AMD Athlon 64 X2 Dual Core)
-CPU cooler: Artic Cooling Freezer 64 Pro
-Memory: Kingmax 2*1 GB
-Video card: MSI NX7600 GT
-Power Supply: Antec NeoHE430 430W
-Hard Drive: Samsung 250 GB SP2504C
-Operating system: Win XP Pro SP2
I would like to control the speed of the CPU fan automatically, according to the temperature.
I tried
-the Dual CoreCenter utility from MSI, but it allows me only check the speed manually (If I did not miss anything)
-control from BIOS HW Monitor setting SmartFan but it does not work at all. ( Iam not sure but this can be because my cooler, it has 3 pin connector, and th MB user guide tells it works only if I use 4 pin connector. Can you confirm this?)
-Speedfan 4.31, it seemed working, but the system become instabile. I check the programmers site, and this MB did not supported.
Do you have any suggesions, experience about controlling the CPUfan?
Thank you in advance!
T.

Thank you for the answers.
Unfortunately the smartfan feature is not working in my case.( set to 3-pin in BIOS) I asked the MSI Technical Support and they said:
As this motherboard includes 4 pins connector for cpu fan, the 4th pin is used to controlled cpu fan speed, if you use 3 pins fan, fan speed will not be changed automatically and smart fan will not function.
I feel a small contradiction here
Do you have other ideas other than smartfan and speedfan?

Kt4a ultra fisr - fan speed controlling

hi,
does anybody know how to control the cpu fan speed when using this mainboard? i tried, as the manual says it, pc alert 4, but it did not do anything. neither does speedfan work.
is there still a chance to have success? the cpu is running @33-34°C (pc alert 4) and the fan is quite loud (5krpm).
thanks
Tristan

CompUSA is selling a very decent fan controller with digital temps read out for like 30 bucks ...It has intercahngeable face so it can match your system build ...It fits an a cd rom open slot and works and looks great ...It does work too but if the fans you have are not speed variabled then i dont care what you use it will never work ...Most CPUs and high quality fans are able to be controlled by a fan controller ...Most cheaps just spin whatever their rpm is rated to spin at ...........

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...

Questions About MSI Z87-GD65 System fan Currents!

Hi,
I have a few questions on the MSI Z87-GD65 System Fan currents. I want to hook up 2-4 120mm case fans together through a PWM Female to 4 x PWM Male Computer Case Fan Splitter and connect it to one of the SYSfans on the Motherboard, but I am unsure about the current limit on the SYSfan1-3 on the motherboard. Also I was unsure if I needed to have a 4-pin connector or 3-pin connector. On the online manual it says that for Sysfans1-3
Pin #1 is Ground
Pin #2 Is Speed Control
Pin #3 is Sense
And Pin #4 is NC
What does NC mean? Do I need a 3 pin or 4 pin connector?
Thank You For any assistance!

NC isn't used.
The sys fans you only need to get a 3 wire fan for the cpu fans a 4 wire fan would be indicated.
The amp rating is 1amp I believe.
If you want to really control and monitor your fans, it is best to use an outside fan controller. I use the Corsair Link in one of my computers which I like, but is overkill.

MB990 and SL - Fan speed is not increasing automatically

Hi Guys,
Two days ago I changed my macbook's hard drive to a bigger one and did a fresh install of Snow Leopard.
As soon as I installed the SL I noticed my computer was running hotter than the previous installation. Without doing anything, my macbook is reaching 75C (167F).. I have already checked the activity monitor and no process is using the CPU. Now I realized that the fan speed is not increasing automatically, it is always fixed at 2000rpm even if the temperature reaches 72C.. I have already tried a SMC reset but the problem persists..
Does anyone know a solution for this? The problem is the fan speed that is not increasing..
I'm having to use smcFanControl to control de fan speed manually. Before the fresh install I was using Snow Leopard updated from the Leopard and I was not facing this problem.
Thanks a lot!

Hi there... i have the same problem. my temperature gets up to 75C with just one window open in safari or google chrome. I have downloaded smc Fancontrol but ...its not enough. have u solved this problem yet? i'm going in to the Genius Bar tomorrow to see if they can help.

MSI 785GTM-E45 BIOS CPU fan voltage control

Hello MSI gurus,
I've replaced the MB in an older HP media center with the MSI 785GTM-E45 running BIOS V8.8 out of the box.
CPU = Athlon 64 X2 4200+
My problem is the stock CPU fan has a 3 pin connection (voltage controlled) and is running at 100% speed all the time. From what I've read on the forums there are a number of people that have this issue (with other MBs with 4 pin cpu fan headers) and don't want to switch to a 4 pin CPU fan (PWM controlled). I am in the same situation.
I am hoping that there is a BIOS for this board that has an option to switch to or enable voltage control on the CPU fan header.
I have tried enabling the CPU smart fan target but no matter what settings I chose the fan remains at 100%. The H/W monitor of the MB indicates a CPU temperature (33C) well below the target (tried all options from 40C to 60C in 5C increments).
I have tried MSI's dual core center and it had no effect on the fan speed.
I have tried the 3rd party freeware SpeedFan and if had no effect on the fan speed.
I am not able to check if I have the latest BIOS or even find changelogs for existing BIOS verions because MSI seems to only direct BIOS downloads for this product to the Live update application. I have installed the live update program and it indicated V8.8 was the most recent veriosn of the BIOS for this board, although I have seen posts indicating the Live Update application is not to be trusted.
Dual core center, SpeedFan, and Live Update have all now been uninstalled.
I know the fan I'm using will change speed because I can connect a 3 pin fan controller and manually dial down the speed.
I know the BIOS can read the fan speed becase it correctly shows the RPM changes when I use the hardware fan controller.
Can anyone direct me to a BIOS version for this board (or some secret keystroke) that enables automated 3 pin voltage control on the CPU fan header?
Thanks in advance for your time.

For those who are interested I received the following answer from MSI technical support. Personally I find this to be a flaw in this board's design. I chose this MB to replace a dead MB in a HP media center for a friend. If I was buying this board for myself I likely would be using it as a HTPC because of the mATX form factor, HDMI on board, and backward compatibility for CPUs. However, due to the added cost of purchasing a new heat sink and fan I would be RMAing if I had bought it for myself. Considering many of the top performing after market coolers still come with a 3 pin fan it was a poor decision for MSI to not include support for automatic speed control of a 3 pin voltage controlled fan.

Dear Sir/Madam,
Thanks for contacting msi technical support team!
We are sorry that because of the circuit designs,we could not add cpu smart function for 3 pin's connector fan in the BIOS. The difference between 3pins and 4pins is that the second has a temperature controller but the first does not.We would suggest you utilize a 4-pin CPU Fan in order to control the CPU Fan speed.
Sorry for any inconvenience caused you!
Best regards,
MSI Technical Support Team

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.
