CPU Fan showing 0 RPM

So I recently bought the MSI z97 Gaming 5 motherboard and I'm absolutely in love with it. Sporting an i7 4790k, MSI 770 GTX, and 8gb of G.Skill Sniper. Enough about the build, my problem is I'm using an NZXT Kraken x61 to cool the CPU, and I found the stock fans aren't adequate enough so I replaced them with Rosewill Hyperborea 140mm's and, while temperatures did drop a little, I still didn't feel like the idle temps were low enough. I broke the bank with this one guys, bought 3x Noctua NF A-14 iPPC's, two on the radiator, one for exhaust. They can run at 3000 RPM max and push upwards of 160 CFM. My problem is I can't view the RPM of these things.
The Kraken x61 has it's own set of 4x 4pin headers so I have all three hooked up to it. Before the Noctua's I had 3x Hyperborea's hooked up to it and I could view the RPM in both BIOS and software. I switched to the Noctua's and now it just shows 0 rpm in both BIOS and software. I can throttle the speeds just fine in NZXT's CAM software, but why won't it show the RPM? I know it's simple to just calculate it, but an exact number would be beneficial. Also this only happens on the CPU headers of the motherboard, if the Noctua's are plugged into the SYSFAN headers, I can see the RPM. Can't have them going off the SYSFAN headers because the Kraken needs to be plugged into the CPUFAN headers. Also SYSFAN can only go down to 50% throttle, and these things are rather noisy.
Any help or suggestions are greatly appreciated

CPU Fan = O rpm. Normal?

Hi everyone,
I'm new to setting up a system so please forgive my ignorance. After getting my system up with Win2000, my PC Alert shows the CPU fan constantly at 0 (even though it's visibly spinning). Temperatures are within the limits. Also, since my casing is a cheapo unit with 400W PSU, it does not seem to have any connector to link to the System fan (SFan1). Yet, PC Alert show the damn thing is spinning. Is this referring to the NorthBridge fan in actual fact? Also, because my RAM is high performance but wasn't on MSI's list, it appears that even setting it up at hiher spec DDR333 causes my system to give red signals on PC Alert's PS Fan Monitor. How can it monitor the PS fan if I didn't plug anything into the mobo?
Can anybody care to comment? I need all the guidance I can get!

you have to use corecell not pcalert. check your fan connections to the mobo too. you cant monitor a fan's rpm if you didnt plug the yellow cord to the mobo.

[VIA] [K7t266 pro2] cpu fan at 0 rpm

Hello,
I've connected my new fan 'Thermaltake Silent Boost' to the three-pin connector of the motherboard. The fan spins perfectly, but when I start my computer an alert is displayed informing me that the fan isn't running (but it is).
When I look at the Hardawre Monitor Setup in my bios, I see 'CPU Fan : 0 rpm'. But with MBM5 or FuzzyLogic under Windows, the sensor works.
Have I some value to change in the Bios ?
Motherboard : k7t266 Pro2
Bios : AMI BIOS
Fan : Thermaltake Volcano Silent Boost K7
Thanks

the fan is at ~2400rpm sothat's maybe why my bios don't detect it as osnavi say.
I don't find any place where to disable fan speed monitoring. Any one has an idea ? (the manual is at http://us-download.msi.com.tw/support/mnu_exe/mbd_mnu/E6380LEv2.0.exe)
I'm afraid I should update the BIOS (v3.5 fix the problem) but i've lost a mobo two years ago because of this...

GPU temperature is above 70 C, and CPU fan is above 2400 rpm

I've had my iMac for two years now. I play a lot of games and watch a lot of HD videos. In the past week, the computer has gotten a lot hotter than usual and it stutters a lot, and I feel like the two are related.
Today while playing a game I noticed that the GPU Diode reached 70 C (using iStat Pro), which I have never seen before. Therefore, the CPU fan was at 2400 rpm.
I play a lot of games, including this same one, and I have never seen the GPU this hot before, and almost never hear the fans running so loudly and so rapidly. (I can't even recall a time when I could very clearly hear the fans running.)
Could all this be a sign to a more bigger problem?

It's all settled down by now but here were some stats I posted earlier:
HD: 53
CPU: 52
Ambient: 30
GPU Diode: 71
GPU Heatsink: 66
Mem Controller: 60
Optical Drive: 52
Power supply 2: 75
Fan speeds:
Optical drive: 1110 rpm
Hard drive: 1100 rpm
CPU fan: 1421 rpm
Which part of the iMac do I blow out the dust? Do I use compressed air (which I have) or a vacuum cleaner? Do I do it through the vent at the back/top of the iMac, or open the memory bay and do it through there (and if so, do I have to take out the memory sticks first?).

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.

K8N Master2-FAR - System fan shows 0 rpm ???

Hi, I just got the K8N Master2-FAR and equipped it with two dual core opterons 265 and 4gb of dual channel ram.
My biggest problem right now is that all the system fans are running at full speed, though the hardware monitor in the BIOS show 0 rpms for them?
At the same time my cpu fans are blowing at about 3600 rpms even though their temperature is only about 36 degrees C...
It sounds a lot like a jetplane, and I'm worried the case will start flying
- what to do, what to do???

Quote from: Djernis on 02-April-06, 18:15:14
I've got the system fans fixed now -Faulty wiring... my own fault
However the speed of the cpu fans are still running 3600-4000 when they are idle at about 36-37 C ???
like what i have said, u can use speedfan to control it..
@admin, soory for using msn stylo....

Fan RPM's read 0 in BIOS no matter where I plug the CPU fan, but it registers in Core Center???

Hey,
I used to have BIOS Rev 1.0, updated to 1.2 thinking it would fix the problem about the Fan RPM's not registering, meaning they show 0 in the BIOS, but it didn't fix it, but it registers normally in Core Center in Windows XP Pro.
What the heck is the problem?? are any other poeple getting this problem?, everything is correctly connected and operates correctly.
Specs are in my signature.
Thank you,
Frank

I have the same problem. Don't worry too much about it. Most BIOS' won't recognize a CPU fan below a certain threshold, and the Thermaltake Silent Boost's stock fan probably fits into that category.

How can i get the max rpm from cpu fan??

how can i get the max rpm from my cpu cooler regarding that i don't have a speed controller attached to the cpu fan ,,, ?? please make things clear for me
thanks

if you have not reduced it by using a speed controller either hardware or software or by the 7v mod its already going as fast as it will at 12 v dc you cannot speed it up only slow it down
need more air get a different cooler/fan

MSI K8N Neo 4 Platinum Smart CPU Fan reports 0 rpm ?

Hi
I have a MSI K8N Neo 4 Platinum (MS-7125) motherboard with an Athlon 64 3700+ CPU and an Arctic Cooling Silencer Ultra 64 HSF.
In the BIOS setup, in the 'Monitor H/W' area you can set something called the 'Smart CPU Fan Target'.
o If I set this to disabled, it reports a fan speed of about 2,280 rpm.
o If I set it to 40°C, it reports a fan speed of 0 rpm ! (the fan is turning)
The MSI Core Center utility and Everest Ultimate also both report the fan speed as 0 rpm.
I assume that if I disable Smart CPU Fan, the fan always rotates at max. rpm; if I set it to 40°C, the fan runs at a slow speed until the temperature exceeds 40°C, at which point it speeds up (likewise if I set it to 50°C or 60°C). However, the fan IS turning.
Can anyone explain this ? I would like the reassurance of having the CPU HSF speed reported.
Incidentally , the PSU is an Akasa AK-P460FG
(3.3v = 30A, +5v = 30A, +12v1 = 14A, +12v2 = 15A)

Very old post yes but I feel the need to reply anyway because I have the same problem myself.
Very strange and would be nice to hear if any more of ya guys out there can see the same.

CPU Fan is always at 5000+ RPM!!!

So I did an upgrade today. I now have a P4 3.0E (prescott) processor, an MSI 865PE Neo2-PFS (Platinum Edition), 1GB of DDR400 RAM, and a new pci-firewire card
The minute I hooked this sucker up everything worked, but the cpu fan is always at 5000+ RPM (as reported in the bios pc health monitor). I thought the motherboard lowered the cpu rpm depending on the temperature, but apparently it's CoreCenter. I use linux and obviously cannot install CoreCenter. Is there any other way I can get my fan to lower it's speed? maybe an equivalent linux software that does the job?

I Agree With Mr. Moleman, as with all of the Heat related Issues that have been Plaguing the Prescott, I would NOT Be Supprised if it is Written into the Latest Precott Microcode in the BIOS, to Run the Stock INTEL Thermal Solution at 100% Speed.................Sean REILLY875

CPU Fan going crazy (over 3500 rpm) all the time iMac 24"

Hello,
I have had an iMac 24" since Aug 2009. I had no problem until up a month ago (coincidentally after I installed Mountain Lion).
The CPU fan becomes very noisy, reaching 3500 rpm and more. I checked and the CPU temperature is around 90C when this happens.
It happens invariably after very little usage of the computer. Sometimes it's when I'm watching a DVD, sometimes is when I'm copying files from a USB hard drive, sometimes I'm just surfing the web.
I have brought my computer to the Apple Store twice already. The first time they told me I should reinstall the OS from scratch, after erasing the disk (which I did), the second time they told me they had found the problem and fixed it, for free! but it presented itself as soon as I turned it on back home.
The CPU temperature is around 80C right now, and I only have safari opened and I haven't reinstalled any program since I reinstalled the OS.
Do you have any idea of what it could be? Could it be that the sensor is detecting a wrong temperature? In this case, could I set the fan speed manually? I know it is not advisable, but the people from the apple store are not helping
Thanks for any help you could give me,
Biagio

Please start by doing a SMC Reset,
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
If necessary repeat process.

Cpu fan is running at -1 rpm!!

h, i've been facing slight problems with my mac that it overheats sometimes, so after some research i found out that i can download a program called fan control where i basically can control the speed of my fans. then i found out that my cpu fan is running at -1 rpm, the desired rpm is 300, my other fans (hd and dvd) are running at the desired rpm, i'm not sure if i should be worried!!! i mean do i have to replace it!? and if so where and how!!!?? btw i've just got this laptop used, it's a 15" late 2008 with the highest configueration.

Resetting the SMC was my first thought, but you have done that. You might also try resetting the PRAM/NVRAM:
http://support.apple.com/kb/ht1379
After that if the issue persists, I would call AppleCare.

CPU fan running at 3900 rpm tried everything so far.

I have an early 2008 imac running upgraded ram, Mountain Lion 10.8. I hve a CPU fan that is running at 3900 rpms. I have downloaded the SMC fan control, I have tried doing the option,command p,r. I have done all the shut down procedures. I tried ro restart in diagnostics mode but it wont restart in diagnostics mode (I tried using option D as well as just D on start up) I downloaded and tried using a shell app command with Automator that is suposed to force the fans tor run at a particular speed ie: 1200,1500,2400 etc. but it does not work. I do not have a start upd disc for Mountain Lion. Don't know what else to do.

I have tried running the hardware test I cannot get it to run starting up while holding D or starting up while holding option D. I do not have a OS X
install DVD 2.

Welcome to Apple Support Communities
It's clear that there's a problem with your Mac, so the best you can do is to make a backup of your files and take your Mac to an Apple Store or reseller to get it repaired.
If you want to know what's failing, run Apple Hardware Test > http://support.apple.com/kb/HT1509?viewlocale=en_US&locale=en_US
In your iMac, Apple Hardware Test is included in the Mac OS X Install DVD 2, so insert it and hold the D key while your computer is starting. Disconnect all peripherals except the keyboard and mouse, choose your language, mark the box to use the extended mode and start the test. At the end of the test you will probably find an error, so copy it here

ODD and CPU fans running at high RPMs

Hello!
My iMac's ODD and CPU fans are running at unusual high speeds. If I turn the computer off and on they usually run at a normal rate but start rotating at around 3700 RPM very quickly (about 1-2 minutes after the OS X has started). The CPU load is not unusually high. The HDD fan is not affected.
I have tried SMC and PRAM resets multiple times.
27'' iMac - Mid 2010 (iMac11,3)
Intel Core i7 2,93 GHz
Boot-ROM-Version IM112.0057.B01
SMC-Version 1.59f2
Thanks!

For some reason the high fan RPMs had to do with having two desktops under mission control.

CPU Fan at zero rpm and temp CPU A 100C

Today I noticed that my iMac was getting a bit hot. iStat widget reported that the CPU Fan was running at 0 rpm and that CPU A temperature was 100 degrees Centigrade!
Rebooting didn't help. Then I let it cool down and did a SMC reset. Luckily this worked, CPU Fan is running again at 800rpm.
I believe that it was pure luck that I noticed this, so I don't know for how long my fan wasn't working. Could this be harmful for my computer? Any suggestions what I should do to check if something is damaged?
What can I do to avoid this from happening in the future?
Best regards,
Jeroen

its connected to the motherboard. and its a simple case fan that lian li gave me. spins at 2200rpms about. and no bios cant see it spinning either and i tried another case fan that i know that works and still cant detect it. it was working fine the other day! it was just yesterday that i noticed core center started beeping telling me its not detecting speed.
