Resolution changed on remote display. Fan runs at HIGH speed.

Today, for no reason, resolution changed on remote display. Option needed no longer shown. Tried SMC and PRAM resets. Now resolution on the MAC AIR is messed up (not full screen) and the fan runs at HIGH speed. This is a sudden change. Have been using the MAC Air in this exact configuration for 2 years. Tried restart/reset of monitor. Nothing. Did resets on MAC and screen changed there. Also the fan runs at high speed.

Early 2008 MacBookPro keyboard backlight off and fans run at high speed

Hi!
I wrote from Turkey.
My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.
What can i do right now? i'll wait for your advices
Thanks

Your Mac may need a new PRAM battery. Once it is over 4 years old, that often is needed.

First uninstall your antivirus. Use only a vendor-provided uninstaller or uninstallation instructions. Never remove files by hand. Never use an "app zapper".
If that doesn't fix it, take it back to Apple for service.

Macbook Pro Fans Running At High Speed

My MBP 17" CoreDuo 2.16ghz came back from having the Logic Board replaced at the weekend. All is well except that now the fans run at high speed all the time.
I have installed SMCFanControl, and the current readings are 45 / 113 degrees and the fans are running at 5500 rpm. I took the machine back to the Apple store but when I was there the fans didn't go above 3000rpm (typical huh?). It's nice that the case is now a lot cooler than it used to be but the fans seem very loud to me.
The question is, is this normal? I am not running anything very heavy duty at the moment. Any ideas?
Thanks
Matt

I tend to agree with Ned on SMC fan control (that it arguably causes more problems than it solves).
I had a similar problem with mine recently having the fans run constantly and at full speed. My temperatures never approached yours, but it would fail to go to sleep etc.
I would start with the advice Ned gave you. This is the same path Apple Care led me down in trying to resolve the issue.
Ultimately though I had to do an archival install of the operating system. It is non-destructive so it wasn't a big deal. I just had to slowly re-install patches and observe behavior. Oddly I was able to patch back up to 10.4.9 without the issue re-occuring so the root cause is still a mystery to me.
edit
Patch gone bad maybe? I tried re-applying the 10.4.9 combo before attempting the archival install route with no success. I know that has been suggested many times. Apparenty it solves many issues, but it failed to solve mine.

Fan running at high speed (iMac 2011)

I'm using an iMac mid-2011 model, 21.5". For the past few weeks, I'm facing an issue where the fan runs at high speed (>3900 rpm). This generally happens when I use the mac for more than an hour with simple tasks like browsing, checking mails, working on word / powerpoint, etc. If I play a game or watch a video, it happens faster in 15 - 30 mins.
I've tried SMS reset several times but it did not help.
I also ran the apple hardware test (extended testing) and got the following error:
4SNS / 1 / 40000000 : TS2p - 121.250
Could anyone help me understand what this error means?
Thanks.

There is a sensor error. That is most likely why you are experiencing the problem. Take it in for service.

Macbook running slow. Fan runs at high speed at times.

I have a late 2008 white Macbook and after installing an upgrade to OS X 10.6.6 it has been running slow in many applications, and the fan seems to run at high speed at times. Not sure if the change in performance is related to the upgrade, or just coincidental. I currently have 2GB of memory installed.

Do this reset perhaps twice:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.

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.
Try it out

Will not boot up and fans run at high speed

will not boot up and fans run at high speed

after much head scratching I ran the hardware test disk from cd. The test showed a memory issue I eliminated the faulty one systematically. So it wasn't a hard drive or software problem in the end it was faulty memory. What was misleading was the computer telling me there was a fault on the hard drive. The machine works fine now. Thanks to people's comments I learned a bit more about the G5 that helped eliminate probable causes

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!

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.

Battery gets very hot during use and doesn't last long, fan runs at high speed, computer won't shut down

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off. Can someone suggest something please.
Thanks.

Kernal_Task consumes 300% of CPU + Fan runs at high speed

Hi all,
I am currently using MacBook Pro 13-inch, Mid 2012.
Since last few weeks this mac has been so slow and the fan began runing at very high speed wich makes noise so loudly.
I then went to a so called "Genius Bar" at the apple retailing store. They did "the neccessary test", they told me so. "There is no any significant problem with your mac, both softwear and hardwear", they replied to my question why my mac became so slow and noisy.
After the dianostic test, they reseted PVRAM, PRAM and SCM... They told me the problems were resolved.
I brought my mac back home.
Oh my Buddha, the problem was still here. By tomorrow morning, I went back again to the store. A "genius man" told me to backup all my data as he needed to reset my system to a new version Mavericks OS X 10.9.1. After reinstallation the new version, we did a test there. Unfortunatly, the result was negative.
They seemed curious with my mac's problems. They suggested me to change MLB, 2.5Ghz, Fan, Front Hard Drive Bracket W/IR/Sleep/HD Cable.
..... Two days after the same story re-appared. I went to the store again. This time they suggested me to change the Topcase, W/Keyboard, No Trackpad,13" MBP-CAN. I paid for that.
It's very anoying. They changed almost everything. I wasted a lot of money and times. The last day I went to the "Genius Bar", the manager told me that they can detect or identify the problem. "What we can do for you is to refund you!", he told me. I really don't like this phrase much as what I wanted was that my Mac should be repaired.
So, my question is that how do we can troubleshoot the Kernal_Task? It consume 300% of CPU. The fan sound loudly even before entering my password to operate the system. I mean just by clicking the power button you can already hear the loud sound. And now I continue working with "MacBook Pro. with Tractor Sound".
Anyone can help?
Thanks

Sokly H.,
what did the manager’s offer of a refund cover — the money that you’ve paid for this series of repairs, or the purchase price of your MacBook Pro, or both?

Expansion Slot Fan running at high speed after installing NVIDIA Quadro 4000

I've noticed that after installing the new NVIDIA Quadro 4000 for Mac on my Mac Pro with Mac OS X 10.6.7 with the newly released NVIDIA drivers (03/22/2011) the Expansion Slot Fan is running at a VERY HIGH speed (between 1,200rpm and 2,100rpm), if I go back the the NVIDIA GT120 everything will be normal with the Fan speed (around 800rpm), does enybody have experienced the same issue ?, thanks

Sorry, that I can’t really offer much help...
Did you install the latest “standalone” driver update...?
Should be currently: GPU “256.01.00f03v7”... CUDA “4.0.14".
The driver has to be present before the card is installed...
Check your latest Mac Pro EFI Firmware update... should be version 1.4.
Run a general maintenance utility like, OnyX, Cocktail, TechTool Pro, Disk Warrior etc.
Restart your system...

Resolution changed on remote display. Fan runs at HIGH speed.
