Monitoring Fan Speed

Is their already a tool availible that can Monitor the Speed of the Fans?
In "iStat Pro" their is a field prepared but the Fan Bar is empty
Who helps me?

Hi Bucky,
I am glad that you like smcFanControl.
About interaction with the CPU temperature:
I decided not to go this route, cause of two reasons:
a) reading out the CPU temperature does not always work. Some macbooks stop reporting CPU temperature after some minutes. So it's not reliable.
b) Interacting with the CPU temperature means you disable automatic fan control and adjust it automatically. This however means if you let the user set the values for any given CPU temperature, the fan speeds might be to low and there is a risk of hardware damage. Another risk might be, that the smccontrol app crashes and while automatic fan control is disabled the fan gets stuck at a certain speed, though the load and temperature is getting higher
It's still not clear which fanspeed is default for which temperature as set by apple. So I decided to just make the minimum fan speed adjustable and let automatic fan control be active - to be on the safe side:)

PSU Fan Speed Monitoring

Power supply fan speed shows zero in BIOS and Speedfan software.
Same zero result when fan signal connector is attached to PWRFAN1 or SYSFAN1.
Visual inspection shows PSU fan is spinning.
Fan speed 1 and 2 work fine.
How do I get fan speed 3 in Speedfan and/or bios to show the PSU fan speed ?

At least on my mobo, there are only 2 connectors that can monitor fan speed, CPUFAN1, and NBFAN1. The other 2 connectors, SYSFAN1 and SYSFAN2 , can provide power to run fans off the MOBO but do not have the ability to "sense" speed or control the speed.. I only have the CPU HS fan connected to the MOBO and the sensor wire from the PSU attached to NBFAN1. All other fans I have connected directly to the PSU.

What are you using for Fan speed AND temp monitor?

Thanks to Bosskiller, my rig seems to be running a bit stabler now! Knock on wood. Is there any program other than MSI's core center that monitor fan speed AND temp? I used to use MBM but it's no longer being supported and CoreCenter doesn't seem all that popular here?

Actually how accurate is the temp reading on HWMonitor for your MSI board? One thing I noticed is that w/ Coretemeter the temp reading was around 48-50c on Rig#1 and almost 58-60c on Rig#2 (That's my HTPC w/ EXTREMELY tight spacings so still work in progress as far as cooling's concern!) but using HWMonitor I got 31c CONSISTENTLY on both rigs! I'll love to think that I'm indeed running this cool but feeling the exhaust air, I think this 31c reading is not real...

Dell Vostro 1400 fan speed

I am not able to get lm_sensors to detect the fan speed, so I installed i8kmon and i8kutils and modprobe i8k force=1 to load the module.
Now the sensor applet tells me that my fan speed for Fan1 is around 27000 RPM and for Fan2 it's around 10000 RPM, while both cores of the CPU are around 50 C.
I've never thought of monitoring fan speed until today, but the figures just seem way too great...
I guess I am not doing it the right way. Any suggestions?

I have loaded this driver and added the newid=0x14e4 0x1713 but still
no luck. Still can not ping the Zenworks server or do anything. The
Network lights stay lit when it tries to obtain an IP address for eth0.
I read on another site that you need to update the initrd with the new
tg3.ko driver. I will try this later tonight and see what happens.

Fan speed on Qosmio G30

My laptop is Qosmio G30-126.
How can I know fan speed?
I've tried some soft with hw sensor monitor & fan speed but it's not show any think about speed fan just CPU temperature?
Where is the problem and what can I do?

hi vip78,
if no 3rd party software can detect the fan speed due to "unknown chipset" there are two options or some more...
- ask your software manufacturer to implement the used chipset, takes long if it will happen
- test other software like mb5 maybe this one can detect this value
generally said: if a software cant detect the value of the fan speed
- either the is the chipset not implemented in your preferred software
- or the value isnt readable cause there is no interface that gives any values to read
it's only important that the bios gives the os some informations about the "heat"-status....
pls go to powersaver options, sure you will get no info bout fan speed, but who cares if your system is working properly!
check mb5, make sure you got the latest version!
good luck

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.

Help with Fan Speed/Temperature Monitoring - 875P Neo Series 2.0

Hi
My mobo manual doesn't explain the monitoring facilities available on this board and I would like confirmation of the following:
My P4 Northwood CPU Fan as supplied with P4 is connected to CFAN1 and provides monitoring of temperature and fan speed and also permits fan speed control.
My Northbridge Fan as supplied with mobo is connected to NBFAN1 and provides monitoring and control of fan speed. No temperature monitoring available.
My mobo provides monitoring of system temperature but doesn't say how this is measured and at what location.
There are two other 3-pin fan headers on the mobo; one is labelled SFAN1 with Gnd, +12V and the third pin NC and the other is labelled PFAN1 with Gnd, +12V and Sensor pins.
My new Antec 500W SmartPower 2.0 PSU has a monitoring cable that is wired with a black Gnd wire and a blue Sensor wire and, according to the Antec manual, is supposed to provide fan speed monitoring if connected to PFAN1 - I have tried this and get no information showing in either SpeedFan or Sandra. ???
My new Case fan, an Antec SmartCool, also has a monitoring cable but only has the third pin wired, presumably a sensor wire, and presumably could also be attached to PFAN1 instead of the PSU signal connector to provide fan speed monitoring. ??? Obviously I cannot connect both the PSU and Case Fan sensor cables to the mobo because the SFAN1 connection has no sensor pin connected; I presume this one is just a power supply to a fan as an alternative to using a supply line direct from the PSU.
Can anyone advise me on the correct use of the PFAN1 and SFAN1 connectors and what they are capable of.

- System temperature is measured at the Winbond W83627HF sensor chip located in front of your PCI slots.
- PFAN1 does indeed monitor PSU fan speed if the PSU has a fan speed reporting header. Not supported by some monitoring software (if Speedfan can't detect it, it doesn't support it. At least not until Alfredo's next revision).
- SFAN1 provides power only, no monitoring.
- Try a different monitoring software and see if it can detect the sensor monitoring your PFAN1. There are other monitoring software out there you can try, such as the CoreCenter that came with your motherboard, or Motherboard Monitor 5 or PCWizard (though you cannot adjust fan RPM through those programs).

Unable to monitor/adjust fan speed? (GX740)

So i've got some gpu heat issues that I was attempting to rectify by jacking up the fans earlier when i discovered the fans operate outside of my monitoring or control... I'm using GPU Monitor 3.5 which picks up the load, temp and any other myriad of information from the gpu but the fan speed is pegged at 100%... even though i can hear it freely adjusting itself. I've tried acouple different programs but the end result is always the same. Any particular reason the fan would be showing no info?
thanks
mike

You can ask Svet to modify a BIOS for you.

Monitoring HDD temps & fan speed in DL2100

Can you monitor the temps of the HDD's with software? Does the fan speed vary according to some inside temp or HDD activity? thanks

Hi,I do not really understand if you want to monitor the HDD's with other software or from the NAS.If you want to see the HDD temp, you have Home> Device> Diagnostics > click on the arrow and you will see the temp and FAN speed. Also YES, the fan speed is changing acording to HDD temp

Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?

My desktop computer m9200T running Win7 Home Premium crashes often. It seems to be temperature related.
I had tried SpeedFan, but my computer crashed everytime I ran it. SpeedFan window scrolled 20 some lines of text than the computer crashed. Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?
This question was solved.

Hi,
Only have one temperature monitoring application running or you could end up with erroneous readings.
Try PC Wizzard. Depending on your hardware, you should see temperatures for CPU, GPU and disk. At the same site you can also try HW Monitor.
I am running a custom motherboard and it comes with its own software for this purpose. HW Monitor seems fairly complete.

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?

IMac (Late 2006) fan speed is 4600 rpm and nothing will change it

I just brought my iMac 24" 2.16GHz Late 2006 back from the Apple Store today and the ODD fan is running at 4600 rpm!!! The noise it generates is way too loud. It is comparable to the wind tunnel G4 I replaced. Any thoughts on how to lower the fan speed?
I took the iMac in on 12 Sep to repair microphone and video crashes. They repaired the mike and replaced the video card with an NVIDIA GeForce 7600GT. I picked it up on 3 Oct.
I have SMCFan and iStat Pro installed to monitor and adjust the minimum fan speed. I tried the usual troubleshooting steps (e.g., reset PRAM, Safe Boot, ran troubleshooting utilities, etc. to no avail.

David,
Looking through my old posts to refresh my memory, my face is red as *I AM* mistaken:O
http://discussions.apple.com/thread.jspa?messageID=4064287&#4064287
I was recalling that Intel iMac users were doing the wrong SMC result three years ago (actually they were doing the SMU reset that was for the pre-Intel G-5 iMacs), and that you and I explained to them the correct way - which is of course what you recommended above:D
Nevertheless, since there is no further risk of causing the fans to race in this instance, I would myself do the wrong SMC reset method, and if it does not work, turn right around and do it the way Apple recommends. This still might result in correcting the problem.
By the way, it was widely reported three years ago that the SMC reset was frequently not successful on the first attempt, so the alternative is to try this harmless procedure at least several times before giving up on it.

Unusual Fan-Speed (up to 6200rpm @ 92°CPU), MBP 2011/ OSX 10.10.2

Dear Community,
I've got a problem with my MacBook Pro (late 2011) [2.4 Ghz/ 16GB RAM (upgraded)/ 256 GB SSD (upgraded)/ 500GB HDD (internal, upgraded (instead of DualDrive, iFixit-slot)).
Since last week I am observing that the fan of my Macbook revs up pretty high and pretty quickly up to 92° CPU temperature @ 6200rpm of the fan according to iStats Pro. This can happen in idle as well as load of any kind. I already cleaned the fan. Never experienced it before. Pretty unusual behaviour.
Do you have any suggestions/ guesses/ tips/ help for me? Thank you very much in advance.
Here's a copy of an (Etre)Check that I just recently ran. Hopefully it helps:

Thank you very much for your answer, OGELTHORPE.
I actually did reset the SMC several times the last few days and also observed unusual behaviour by the use of the Activity Monitor – with no result.
The CPU temperature as well as the fan speed can be at a top level without many processes at all. Happened right before I posted my question just after the last start of the system. Of course it also happens when I run a whole bunch of applications, but even in that case it differs. Sometimes it goes up, sometimes it's totally normal. That's why I called it "unusual".
Any further ideas besides the SMC reset?

Xorg 1.6, nivida drivers, and fan speed

I know the older nvidia drivers are not compatible with the new xorg, nor the nvidia-utils as I tried and found out!
I have 2 issues with this pc: I have a 6800gt nvidia card and the fan is constantly near 100% or close enough! I tried to install and run nvclock but it wont change the fan speed for this 6800 model. My xorg is below but I am not sure the drivers are working too good as the glxgears are only 140fps! I have a an older laptop with a smaller graphics card getting over 1000 fps!
NOW, before anyone gets excited I know glxgears is not the "best" benchmark, but its a decent one and accurate enough that I wont go from 140fps using it to 1000 fps using a similar bench.
I also tried to update the driver to the nouveau-drm driver but not sure if its installed or how to get it loaded in xorg. Any suggestions on these 2 issues?

Any suggestions on this nvidia issue?

Mac mini slow and high fan speeds

Hello! I have a 2011 mid range mac mini and love the machine, however I have noticed a few things. First off, it seems to be a bit on the slow side when multitasking. I have the standard 4 gigs of ram installed, but running programs like MS Word and Safari at the same time, the machine seems to struggle a bit. Also I have noticed when doing a lot of file transfers via USB, the fan will kick up to high gear for a few minutes and then drop down. Is there something wrong or is this normal? I'm doing a time machine backup of 120Gigs, have safari open and activity monitor open.
Activity monitor states 1.16Gigs free, 792MB wired, 961.4MB active, 1.12GB inactive, 2.84GB used. VM size is 150GB, page ins are 962, outs are 380kb, swap used is 10.5MB. Right now the fan seems to have slowed to a mid range mode of some sort and is not in high gear. Thanks!

How many apps you instaled? how many pictures videos and time you get usigm it? let them a litlle sleep, and your mac nmini will ne wel.
As far as the fan is concerned, it will rev up and down
based primarily on CPU load. If something is using
up a lot of processor, it gets hot and therefor the fan
speeds up to cool it down, or atleast maintain a safe temp.
When the fan revs up, open Activity Monitor and see how
much processor resources are being used and look at
the list to see if any one process is using up CPU. This
can also give an idea of what may be slowing things down
as well.
And yes, when doing a lot of file transfers, things may
possibly rev up a bit if it is continuous for a period of time.
