Ideapad Flex 2-14D: Fan constantly running at high speed: Windows 8.1

Hello. I have an Ideapad Flex 2-14D running Windows 8.1 and actual drivers.The fan runs constantly at high speed. So I have not to complaint about overheating, but instead I have to complaint about getting cold knees. Is there a possiblity to adjust fan speed? Best regards Eleichstetten

I've tried SpeedFan and looked through all the Lenovo programs, but there's no way that I can find for tuning the fan. My ghetto hack is to limit the CPU to 70% max (with Passive as the cooling scheme), which keeps the fan well under control.
Fan adjustment should be a standard feature in 2015. It's not expensive and definitely not difficult to implement.

CPU Fan - constantly runs at high speed

Just like the title says, my CPU fan is constantly at a high speed. It's loud and I haven't been able to figure out how to set it back to normal. It's a Dell Optiplex GX620. I swapped the power supply, re-imaged the hard drive, and flashed the BIOS to the latest version from dell's website. I looked through all the BIOS settings and logs and didn't find anything. I've asked every IT I know, and gone through a million forums with no real explainations or ideas to this issue. So far the best advice I've got is to turn it off. My theory is if I find the driver that controls the CPU fan and update it, the system won't see the CPU as overheating and it will return to normal. I'm close to just replacing the motherboard but thought I'd post something first. Anybody have an answer?

Go to www.AMD.com or
www.VGA.com and post your problem in the forum that best fits your problem or start a post of your own. Be a lot more detailed then you are here about all the equipment it will be very important when trying to diagnose. Do not throw out your mother
board and stop replacing parts your waisting loot. when you go into the the AMD web site and post under the proper forum You are going to hopefully run into one of three people Gr33nGecko, SteveO_Crossfire or Black Zion these three people
are experts in there field and have forgotten more than most people know. If stevo responds to you he will have a website posted in blue near the bottom of his post or ask him to show you his system you might want to be sitting when you see the unit
for his house. I could run a good size town on the darn thing and wait to you see the cooling tower on top. Iv'e seen smaller units on power plants lol. Just joking but the darn cooling tower is still huge . I know Gr33 is in several forums as a
supermoderator and has over 17,000 post listed that I am aware of. Well good luck and dont give up.
I know of several reasons your unit maybe overheating but I think you would be better off with anyone of these three techs. and it would be good if you had a second computer/laptop near you. When I am working with them I use a lap top that way I can
do voltage checks or whatever and I am responding with questions and answers without delay and I am not blowing up my computer or myself to answer or check a problem that would normally require me to shut down my problem computer and still be able to
talk with the guys.
Good luck

MacBook Pro's fans start running at high speed when the computer is asleep. Normal?

The other night, my MacBook Pro's fans started running at high speed when the computer was asleep. Loud enough to wake me up. And this just kept on going until I finally decided to turn the computer off. Is this normal? Is this anything to worry about?

This is not normal. See if a SMC reset solves the problem:

Fans still running at high speed after smc reset

I have an i Mac Version 10.6.7, 4 GB RAM and 2.66 GHz Intel Core i 5 and since yesterday the fans are running at high speed. I tried to reset the SMC as instructed on Apple Support Site but it won't help.
Does anyone have an idea?
Thanks.

Try the reset again. Sometimes it takes several. This time leave it off wall power for an hour before holding in the power button.
If that doesn't help, run the Hardware Test in Extended.

Macbook pro fan constantly running on high

Hello i have a problem with my macbook pro
as soon as i start my macbook pro early 2011 up the fan goes immediately on high speed and when i look on on istat it says that the fan in going 0rpm but when i push above the F6 and F7 it suddenly stops and the fan goes to 2028rpm i have tried the smc reset and such and that doesn't work at all. I have looked at activity monitor and there was nothing strange as well so please does someone know how to stop this, its really annoying.

Most intereseting. The display shows temperatures at very acceptable levels but zero fan speed. That cannot be. Try a Apple Hardware Test:
http://support.apple.com/kb/ht1509
You may have to use the OPTION and D keys to start it.
Lets see if that picks up anything.
Ciao.

I'm wondering if anyone else has had problems with their imac fans being extremely loud when running at slow speeds? When the computer heats up enough for the fans to run at higher speeds they quiet down. New HD fan was just installed.

I have an imac that I've had for a couple years. The fans have always been loud when running at the slower speeds. When the computer heats up enough for the fans to run at a higher speed the fans quiet down. I had installed SMC fan control after multiple attempts with Apple to get the fan issue resolved. That seemed to keep the fans quiet enough. I've never had a problem with overheating. Recently the fans were becoming loud again even running at the slightly higher speeds so I took it to my local Apple store and they replaced the hard drive fan. I got it back and it's now as loud or louder than ever!! And, now SMC fan control won't "stick." The fans will speed up, but then gradually go back to the lower "loud" levels. I'm at a loss as to what to do next.

Thanks jared,
I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.

Z77a-g43 cpu fan constantly runs at max speed

I have a Noctua dh14 (without a pwm connector). My old 870a motherboard had a setting which let me pick if the cpu fan should be controlled by voltage or pwm, but I can't seem to find it on my new z77a motherboard. Is there anything I can do about this aside from connecting the fan to some sort of external controller?
I can see the motherboard changing the fans PWM value in hwmonitor, but the rpm remains the same.
Edit: I was able to do it by switching to the system fan connector instead of the cpu fan connector
It would still be nice to know how to adjust the fan speed on the cpu fan connector though.

Quote from: Henry on 19-May-12, 08:00:09
Put a 4 wire PWM fan on it.
That or connect it to an aftermarket fan controller or a system fan header like was done.

Fan is running on high speed, no signal to the monitor!

Hi!
I have the following Problem with my G5:
It worked perfectly, but suddenly yesterday, I switched it on, it began just like always to boot the system, but i had no signal to the monitor.
After a couple of seconds the fan started to run very fast and did not stop anymore (at least for then minutes, then I switched the G5 off, because it's annoying)! I've treid it again, but the same Problem occured...
Has anyone else already had this Problem?
What are the reasons for this, and how can i solve this Problem?
Cheers, Markus

Hello Markus, and a warm welcome to the forums!
Boot off your original G5 Install Disk while holding down Option/alt key to select AHT, then run the extended Apple Hardware Test.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot.

Cooling fans constantly run @ full speed after replacing the upper CPU??

After replacing the upper CPU on a Power Mac G5 (June 2004), Dual 1.8Ghz PowerPC, model M9454LL/A, all the cooling fans constantly run at full speed. All other operations are normal.
I've read, "...after replacing or switching CPU locations the Logic Board doesn't properly recognize the CPU's in their new location and a "Thermal Calibration" is needed". Could a "Thermal Calibration" possibly correct the constant full fan speed issue?
What software would be required?

Hi-
Could a "Thermal Calibration" possibly correct the constant full fan speed issue?
Yes.
What software would be required?
The Apple Service Diagnostic disc (ASD) of the proper version for your machine.
Call an authorized Apple service provider and arrange a calibration, as the disc is not readily available to individuals.

HP G42 Fan Running in High Speed and Noisy

I had a HP G42 i5 notebook. Recently I send my notebook for repair due to the graphic card problem. I encountered that the fan speed is running in high speed mode after I the repair. I asked the incharge and he told me that they had did the cleaning on the notebook, so the fan will run in high speed and making noise. I did told that person, it was silence before repair and the fan will only run in high speed mode when the notebook's got heat up. But now it's got into the high speed mode even during startup time.
So I would like to get some advice or comment on this. Is it normal that the notebook's fan speed is running in high speed and noisy since startup? Thanks in advance.

Hi Richard-G,
I'm sorry for the delay in my reply, as I have been out of the office since last Thur. The instructions would have been the same for your notebook, but not the same BIOS.
This document will guide you through updating your BIOS if you wish. Since the noise is reduced once Windows begins, I would not worry too much about this.
Good luck!

Why does my mac pro fan run at high speed?

My Mac Pro cooling fan started running at high speed. Tried all the shutdown and restart options but didn't help. Suggestions?

The fan runs if something is overheating or if a sensor has failed or there is a problem with the SMC. So, reset the SMC - Intel-based Macs: Resetting the System Management Controller (SMC). If that does not stop the fan from running then check for a runaway application:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
If the problem still persists then create a new admin user account, logout of your account and log into the new account. See if this fixes the problem.
If none of the above help, then you may have a hardware issue such as a defective sensor.

Re: Satellite C55-A-1JL - fan running at high speed after BIOS update

Hello,
I' ve upgraded BIOS from 1.20 to 1.40, and my computer started to restart automaticly after few minutes. the fan keeps running at high speed all the time
Anyone know why?

Question: does the notebook work properly besides the fast running fan?
Generally speaking after the BIOS upgrade you should always load the BIOS default settings.
In BIOS press F9 (load default) and then press F10 to save changes.

IMac 27" - i7, Fan running at high speed - roaring noise

I just bought an iMac 27" i7 with 8 gig of RAM and the upgraded 2 gig graphics card on 09/28. All of my stuff transferred from my old iMac without any real problems. I turned the system on one morning and after about 2 1/2 hours of use the fans starting running in high speed mode - the noise is unbelievable. It's so loud you can't possibly work or make a phone call on speakers. Keep in mind I'm using the system with the same software and in the same manner as my older computer. I took it to the Genius Bar and they couldn't determine what was wrong with it so they are replacing the machine.
Anyone else have this problem?

Before taking it in do a SMC reset, you should also run Software Update and update to 10.6.8. If the reset doesn't work the first time then do it 2-3x it will not hurt anything. Also please follow the instructions as described.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My mid-2012 MacBook Pro has the fan constantly running. As soon as I turn it on. My MBP won't even be hot and the fan is running. How can I fix this?

If you are still under warranty and/or have AppleCare, call them. Let them deal w/it.
