MSI H97 PC Mate CPU Fan RPM Control Cruve Question

My planned build:
Project "Bad Wolf"
CPU: Intel Pentium G3258 3.2GHz Dual-Core Processor
CPU Cooler: Cooler Master Hyper T4 70.0 CFM Rifle Bearing CPU Cooler
Thermal Compound: Arctic Silver 5 High-Density Polysynthetic Silver 3.5g Thermal Paste
Motherboard: MSI H97 PC MATE ATX LGA1150 Motherboard
Memory: G.Skill Sniper 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Seagate 1TB 3.5" 7200RPM Hybrid Internal Hard Drive
Video Card: Asus GeForce GTX 960 2GB Video Card
Case: Deepcool TESSERACT SW ATX Mid Tower Case
Power Supply: EVGA 500W 80+ Certified ATX Power Supply
Case Fan: Cooler Master R4-L2R-20AC-GP 69.0 CFM 120mm Fan
Case Fan: Cooler Master R4-L2R-20AC-GP 69.0 CFM 120mm Fan
Case Fan: Cooler Master R4-L2R-20AC-GP 69.0 CFM 120mm Fan
As you can see within my build list am getting Cooler Master R4-L2R-20AC-GP 120mm fans for my case (For short I'll call them R4 fans) and I would like to replace the stock fan from my Hyper T4 with an R4, because they are much quieter than the stock fan and have nearly the same airflow and since I'm getting a side window case it'd be nice to have an LED lit fan in the middle of my case
However the R4's are 3 pin, not 4 pin so they don't have PWM control. Is there a way to set up the H97 PC Mate to control a 3 pin fan in it's 4 pin cpu header?
I talk to MSI over the phone the guy said that it should be able to control the 3 pin fan through the cpu header via controlling the voltage. He said to look it up online to see if I could find how to do it, and to download the user manual and look through it, but I couldn't find anything on how to set up the BIOS to do that.
If I can't I'm not even going to bother to buy a third fan.

Hi
CPU fan headers are only able to control PWM fans(4 pins). If you lut 3 pin fan into it, it will run 100% possible speed.
SysFan headers can control 3 pinned fans by voltage increase/decrease, between 50-100%. And PWM fans of course too will work.
Maybe a fan splitter, or an actual fan controller would do? I have a controller myself for all 6 fans

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,

[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.

Sorry, BIOS is Rev 1.0, CPU fan RPM still wont show, on Promise SATA and I have no activity led??

Yes, everything is properly connected, CPU fan is on CFAN1 and the HDD is on the Promise and the front panel led connector is properly connected.
Anyone know what the heck is wrong?? maybe my board has LED on VIA and not Promise opposed to Promise having it and VIA not??
and why won't my bios display the damn CFAN1 RPM's??? I tried every connector also.
any help?
thank you

Ok, this is weird, the HDD led connector was connected as directed in the manual, black (ground) on pin 1 and red (+12) on pin 3, whats weird is that I flipped it upside down (red on pin 1 and black on pin 3) and now it works, that just weird but at least it works now. every other connector works when connected normally, funny that I have to flip the HDD led connector upside down haha.
Anyway, still can't figure out the CPU Fan RPM, why it displays 0 while the Fan is actually running?? I don't know why.
Have you heard of that problem??
Thanks again guys.

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%).

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!

Quote from: PCArcade on 25-September-14, 16:12:39
he cooler is a Noctua NH-D14 with stock fans (non PWM)
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.

CPU fan RPM much too high on startup on Z97 U3 Plus Board

Have two Z97 U3 Plus Boards, and for some reason with same settings and same hardware and software they continue to display different bugs with both the same BIOS versions.
On one board, cpu fan runs insanely high on power up for about 4-5 seconds before slowing down to normal. Any idea how to resolve this?

I wonder why the fan on the second board is so quiet at startup then. Must be something to do with QC at intel then I guess as they are both stock fans.

CPU Fan Speed and Memory Questions

I"ve noticed recently that my fans sound a little different. When using aperture and sliding some of the image adjustment controls the fan will increase as I'm sliding the controls and stop when I stop.
I've been monitoring with istat pro, and my CPU fan is almost always at 0, I've seen it not at 0 a few times but very rarely.
Readings:
Power Supply: 599
Exhaust: 655
CPU Fan: 0
HD/Expansion: 499
Temperatures seem normal except northbridge has always run a little hot since I got the machine. About 180F
I did the hardware test and the message I got was:
4MOT/1/4000002:CPU_MEM
I'm assuming this means that one of my memory chips is bad but where do I go to find out what this code means? And does this mean there is no problem with my CPU fan or did the test just end when it found this error?

Good news about the RAM. Have you checked to see if the fan is gunked up with dust and dirt or some other obstruction? Could free it up or be the source of a fan failure.
A simple procedure is to reset the SMC (System Management controller). Here are Apple's instructions:
http://support.apple.com/kb/HT3964
The SMC has control over the fans. The reset won't do any harm but follow the instructions.

MSI GTX770 Gaming minimum/idle fan RPM?

Hi - first post here
I am looking at buying a new GTX770 - haven't decided which brand yet. But I have a question for current owners of the MSI GTX 770 Gaming model.
When idle what RPM does the Twin Frozr fans spin at? And what is the minimum you can set them to?
I ask because it is important to me that my system stay as quiet as possible. I read that some GTX770's bios wont allow lower then 1100-1200 RPM (EVGA in particular). What is this like with MSI?
Thanks in advance

Any1 with this information? Would be much appreciated.
-thanks
Hi, I have the same issue on R9 270 which of course is a different card. Some other users I can read have that too. I contacted MSI and they replied the following:
"The GPU temp is normal, 78C under full load is similar to what we received under similar test with MSI Kombustor and FurMark, max temp we received was 81C, a bios update will not alleviate this, the chipset naturally runs a bit hotter, If you would like it to run a bit cooler then you may carefully remove the heatsink assembly and add a new layer of quality thermal compound to see if it drops a couple of degrees, nonetheless the temp at 78C is considered normal and within the cards tolerances. If you believe there is an issue with the physical cooling fan then you may send the card in for inspection to your most nearest MSI service center."

I want to quiet down a P4 1.6A CPU fan and Sparkle PSU

Hi,
I want to quiet down my P4 1.6A CPU fan and PSU fan....
A) I have a MSI 845G-MAX-L motherboard with Winbond monitoring chip. I notice that the CPU fan RPM goes up when temperature goes up. Is this normal on all boards, or is this an extra nice feature specific to MSI boards with Winbond chip???
B) I've already put a FanMate to the CPU fan, and it runs at 1500 RPM, but I can still hear it.... so now I have a Zalman fan bracket (FB123) and am searching for a 80MM which has RPM sensoring, to give me some feedback in the BIOS and MBM5. Any suggestions on a quiet 80MM which has RPM sensoring.... (I've tried Coolermaster and Vantec.. they are both noisy to me.... I tried Panaflo but I want the RPM sensor so I can tell if the Winbond chip is doing it's job of speeding up the fan when the CPU temp goes up....
C) I have a Sparkle 300W-BTV PSU. Does Sparkle solder on the PSU fan tail to the pcb or do they use some pin header?? I'll probably replace the PSU fan with Panaflo. Also does Sparkle use a thermistor to control fan speed or is it just one speed? I can use the Coolermaster DAF-B82 which is quiet at startup (1000 rpm) at 20 C.
D) I am thinking about getting the OCZ P4 eliminator passive heatsink.... anyone using it or seen a review of it? Can the Alpha 8942 run in passive mode with no CPU fan? I only have the Sparkle PSU fan as the exhaust fan in my Coolermaster ATCS-200 aluminum case.
Thanks.....

My CPU runs at 37 C at idle and the CPU fan is at 2400 RPM. When running loaded (at 100% utilization after 1 hour) my CPU temp runs at 41 C and the CPU fan is at 2800 RPM. During the summer when ambient temps were very high I've seen my CPU temps at 43 C and CPU fan speed at 3000 RPM.
I read a little on the Intel Precision Cooling Technology. I believe that the Intel Precision Cooling is capable of adjusting the SYSTEM case fans (along with the CPU fan). It seems that Intel went one step further by adding in SYSTEM fans and then adding in the ability for the user to control both the CPU fan and SYSTEM fans based on temperature.
What I'm wondering is if all or most P4 motherboards adjust the CPU fan speed based on CPU temp (in real time), or is this just something new that MSI did in their later boards like my 845G MAX? Anyone have other P4 MB (other than the obvious ones by Asus and the ones which have the Intel Precision Cooling) who can comment?

CPU FAN SO LOUD!

So after installing all my new pc parts (FX-8350, MSI 970 Motherboard, GTX 750ti) everything is working as it should, but the CPU fan... (CM Hyper 212 EVO)
everything is default on the motherboard but ive put my ram speed to 1866MHz but that's not my problem. my problem is that when I'm playing BF4 (or anything CPU intensive) obviously the CPU is going to heat up right? but when it's under load, about %70, the CPU fan will be spinning at about 400rpm, at %70 load still but then suddenly it boosts itself right up to %100, and it's so loud! I've tried setting a fan curve on the hardware section of the bios,(as temperature increases, CPU fan RPM increases) but it just doesn't do that! and also while it's under load the cpu fan will be at %100 then drop back to 400RPM, is there anywhere that can tell me how to use the fan curves? thank you!
*SHORT*
CPU fan curves not working

Hi,
Try to change (within BIOS) from "Smart Fan" to manual control and set minimum value of 25% and max of 100%. Then you should be able to control fan within Windows using Command Center and if you need 100% you will set to it, else you can have it lower.
What is the actual CPU temp when it hits 100%?

Is My CPU Fan dying?

Recently installed new MOBO (see below) and CPU (see below). CPU Fan RPM's have been running 4015 constant. (My previous CPU 1700, the fan ran constant 4400). Temp on new CPU stayed constant at 43C to 45C range. Last night, jumped to 64C after I installed Motherboard Monitor and PC reset. This is the stock heatsink that came with processor. I shut down PC overnight and fired up this morning and it's staying constant 25c so far. Should I consider replacing original heatsink with something else? Here are my specs in case my signature doesn't make it. Thanks for you help.
-Motherboard (MSI MS-7051G)
-Bios (Phoenix V3.20)
-CPU (AMD Athlon XP2700)
-Memory (Centon 2X512mg)
-Video card (NVidia GeForce FX5500)

the thermal paste just had to reseat, if fan is changing speeds at will, i would just replace the fan. 25c is a good cooling

Platinum sli 7125 - temp / fan rpm sensor playing up

Recently installed a new nexus fan and a psu into my system ( see sig) and finding the fan and temp sensor chip is giving me odd readings...
It was fine previously and reported the consistent values through corecenter, speedfan and everest
Now I am sometimes getting temps of -99 for cpu, fan rpms dropping to 500pm on cpu even though the speed is not changing.
All readings from corecenter, speedfan and everest tally
It is solved by a quick reboot so a little confused as to why it is happening?
I do have the latest bios 3A, which was put on 6 months ago, no changes recently apart from the new more powerful psu and a new rear case fan (replacing my older antec one) which is running off s_fan1 3 pin point rather than the antec one which ran off the psu directly
I may try swapping the nexus to run off the psu directly...
thoughts welcomed
thanks

odd
all is back to normal it seems
I can only conclude that there is some spiking or irregular current flow via the 3 pin wires off the nexus...
it is now fine off the psu - good thing the nexus is only 22db at 12v ! as I could not bear to go back to the antec fan at 12v
