MSI B75A-G43 runs fans at full speed for 1-2 seconds after powering on the PC

Hello fellow MSI owners,
I have a MSI B75A-G43 board and i was really curious why does the fans run at full speed for 1-2 seconds when the PC gets powered on and then gradually quiet down to normal speed. Other than this, the board works great. I have had only boards from Gigabyte previously and they do not exhibit this behavior, is this a MSI thing ?
Thanks,
Alex

Thanks for the answers fellas !
Indeed it looks like normal operation on the MSI boards ( may differ on the latest Bios versions maybe). PWM control probably works differently on the Gigabyte ones

Cooling Fan ran full speed for no reason

iMac G5 17in 1 meg ram less than year old. Was sitting there in sleep mode and fan started running full speed for no reason. Computer screen black and would not wake up with keystroke. Shut down computer via rear panel switch and restart, all fine now. Do not understand why this happened but suspect it is actually a software problem, see below. Anyone have an idea so can understand what happened?
My iMac has the combo drive, not superdrive. I use an external 8x DVD burner for backups and iMovie. Yesterday I burned a iMovie (short) just fine. Then decided to back up my some of my Movie files along with iPhoto and iTunes media files. I tried three times but the burner did not work as usual. The first copy failed to verify and when I put it in the iMac slot, dumb I know, it did not show on the desktop. I restarted the computer to eject the disk, worked ok. The second copy did not work either, but did not put it in the iMac. The third copy burned but took a few hours to get 39% verified. I tried to stop the process with force quit, but it would not quit. Finally shut down the iMac via rear panel power button as a last resort as nothing on the desktop would respond to a mouse click. Computer restarted ok and worked fine for several hours until it went to sleep as I did last night.
I know using the power button is a last resort and possibly there is a keystroke that can force a proper shutdown. Also suspect the DVD external drive is balmy now, BenQ. But was amazed that the iMac still seemingly had some bug up its operating system this morning causing it to freeze and the fan to run full speed.
Again, any ideas...now be nice....I have tender ears
btw have three year warranty and just love the Mac, am going to sell my Dell laptop and get a PowerBook real soon.

Well the problem is fixed. I did call Apple Support and they ran me through the hardware utility. The problem I reported was that the system took forever to startup and that once the fan ran at full speed for no reason. I was not aware of the slow boot when I wrote this question so did not refer to it. But, after the DVD debacle my iMac would hang on the black screen just after the chime for about a minute or longer. The system worked fine once booted. This long boot came from both restart and a cold start. Think it happened once when I was trying to wake it from sleep yesterday, that is when I shut off the 'puter with the poer button. Anyway, the disk utility showed no problems
The Apple Careperson was very nice and stayed with me until the issue was resolved. It turnes out that unplugging my USB hub cured the slow bootup problem, and probably the fan.
So I am guessing that something in the external DVD hardware went and damaged the USB hub. It would be too odd for two devices to fail, on their own, at the same time.
The good news is that I just found a nice LaCie external DVD with firewire 400 support, so guess what I am buying.
As for the USB hub, well without the external DVD I don't need it right now so will wait to replace it.
Thanks for your help and I hope this may help someone else down the line.

Mac Pro, Fans fire up full speed for no reason - randomly!

So, here is another fan issue with the Mac Pro, and I am at a loss. Perhaps someone can help me with this one. I have a Mac Pro I bought in mid '07, dual 2.66 GHz. I have 2 7300GT video cards, which don't have fans of their own to be making the noise...
The computer, when left doing nothing will ramp up full speed for God knows what reason. There is usually almost nothing open for applications, and no major processes running. Menu Meters shows the processor load to be minimal, not a heavy load that would cause heat-issues from processors working hard.
There is really no way to get the fans to slow back down either. The machine is still fully functional, I can open, close or work on software, so nothing is "frozen". I have quit all applications to no avail. The machine will not go to sleep when this occurs, and half the time will not power off using the shut down menu selection either; requiring a forced shut down. Upon reboot, it is fine... (until it decides once again to take off).
This is not the fans roaring when waking from sleep issue, I have had that one as well (bad ram).
Thoughts?

Last night, after I shut down, my fans slowly ramped up into high gear. They went to full rotation, and I let it whirr for four or five minutes, thinking it would shut itself off. It never did, so I just pulled the plug on the CPU. I plugged it back in five seconds later, and it stayed shut down after that.
It's been working more or less flawlessly other than this... most stable Mac I've ever had.

Mac Pro will not boot, revs fans at full speed

Hi,
I had my Mac Pro (2006 3.0 quad core) asleep, it woke itself up and didn't display video, instead revved the fans at full speed and did nothing, so I shut it down using the power button. When I turned it on, it did/does the same thing, no chime, no video to the displays, and I cant boot in safe mode or any other way, it wont even eject the DVD drive if I hold the mouse down.
has anyone encountered this before?
Any ideas?

Give the SMC button a kick, hold it in for 5-10 seconds. Hard to see, but hidden by drive #4.
Or try zapping PRAM/NVRAM first and see if that helps.

IMac 10.1, OS X 10.7.5, 4 GB RAM, 201 GB free on 999.35 GB HD, gets slower the longer I use the Internet; very noticeable with online browser game Forge of Empires. Turning iMac off and restarting it brings it back to full speed for an hour or so.

iMac 10.1, OS X 10.7.5
4 GB RAM (2 of 4 slots used)
201 GB free on 999.35 GB HD
The iMac gets slower the longer I use the Internet - to the point that it takes several seconds for each typed character to appear. This is very noticeable with the online browser game Forge of Empires. But, it happens even if not logged on to that game.
Turning the iMac off and restarting it brings it back to what seems like full speed for an hour or so. Then, it starts to noticeably slow down again.

1st thing : from my point of view upgrade your mac os to latest version.
                (their is mac os x mavericks from apple its free for upgrade so download it and install it.)
                (https://itunes.apple.com/in/app/os-x-mavericks/id675248567?mt=12)
2nd thing : then upgrade your all browser plugins to latest version.
3rd thing : and use ccleaner to keep clean your mac from junk data or other unuseable data that are created.
                               (http://www.piriform.com/mac/ccleaner)
4th thing : verify and repair your disk permissions with the use of disk utility or ccleaner
i am sure your computer recover speed.

G500 fan running at full speed for no apparent reason

I have G500 that worked perfectly for a year now. My operating system is Windows 7 Professional. Yesterday the fan started working full speed while the laptop was idle, I wasn't using it and the software that was running in the background were the usual programs I have been running for the last year. First step was to check the temperature of course, which is normal. Then I checked if anything weird is running in the background and creating high cpu usage, but that was not the case either. What I noticed though was that fanspeed is not recognising the fans or counting their speed. Is it a problem on the hardware? It is really annoying. The speed also fluctuates very often, reminds me of how it should work while gaming and definately not when idle.
Thanks

Hi Zoe,
Welcome to Lenovo Community!
As per the query we understood that you are facing fan issue in your G500 laptop.
Please try to boot the system to safe mode and check for the issue.
Also perform a clean boot and check for the issue, if still the issue persists try to update the BIOS and check for the issue.
Click here for the BIOS update.
Hope this helps. Do post back if issue persists!

MSI 970a-g43 CPU fan always at 100% when fast boot or MSI Fast Boot is enabled

I turned on fast boot in my motherboard in my BIOS but now whenever I boot into windows the CPU fan is always at 100%. I really like the performance gain from fast boot, however I can't stand the CPU fan always at 100%. The fan normally runs at ~1150rpm when its off but when its on it runs full blast ~2800rpm.
My specs are:
MSI 970a-g43
AMD FX 6300
MSI HD 7870 OC Edition (Flashed with GOP vBios)
2x4 8gb DDR3 g.skillz ram

I have it set to 55c smart fan control in the BIOS. With fast-boot off it works perfectly. It seems like its not lowering the fan like it normally does when its on. If I go into the BIOS and reset it it'll work fine the first time, but after that it'll do the 100% fan speed all the time.

MOVED: Fans on full speed after graphics card removal

Don't know if this is the right place to post this, but I'm pretty sure it has to do with the graphics card.
So a few weeks ago, my NVIDIA video card was damaged. Short-circuited or something, but there's a burn mark over one of the modules and it was preventing my computer from turning on. It had to be taken out or replaced, and because I didn't want to spend the money replacing it, I opted to remove it and just use my integrated graphics card in my laptop.
However, now the fans in my laptop are running at full speed all the time, regardless of CPU/GPU temperature. I've searched over several forums for a solution, and I've looked into several different programs, including MSi Afterburner, NVIDIA GeForce Experience, SpeedFan, Riva Tuner, and RWEverything, but to no avail. Most of them require a video card in order to control the fan speeds, but since I don't have one in my computer, I can't change anything. I've also looked into the BIOS, but it doesn't appear to have any fan controls.
I'm pretty sure the fans are running at full speed because they can't get temperature data from the (missing) card.
Laptop:
- MSi GT60 0NE
- (Had a) NVIDIA GeForce GTX 675M
- Integrated Graphics: Intel HD Graphics 4000
- Running Windows 8
Any help would be appreciated, and I can provide more info if needed! Thanks!
Have you checked if your bios have a graphics switch or w.e it's called where you can switch from Nvidia to UMA GPU = Intel gpu ? if your laptop dont have that then nvm about it

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

MacBook Pro heating up and fans at full speed

MacBook Pro heating up and gets extremely hot and fans constantly at full speed after upgrading to Yosemite 10.10 without even launching any applicaiton previously I was on Mavericks, I checked Activity monitor and a process called kexts is always running and have a large percentage of the CPU load I tried reinstalling Yosemite and the same problem happens.
MacBook Pro 13 inch Late 2011, 2.4 Ghz Intel Dual Core i5, 8 GB 1333 MHz DDR3, Intel HD graphics 3000 512 mb.

Thank you That solved my issue I uninstalled Cisco anytime connect. My console had that kernel running in the background giving the error every second.

My fan spinning full speed, no appareant reason.... Help!!!

I have my pb since septemer 2005 and 2 weeks ago, the fan inside the book started to ran for nothing, the cpu usage is low, temperature ok (45C), i've tryed a fresh install of os x 10.4, to zap pram/vram/power management, to reduce cpu to minimal setting, apple hardware test and it did nothing. Now the fans of my PB run full speed 50 % of the time, even during startup... It's annoying (it sounds like a pc)
It's the fan at the right, maybe under the right speaker or something like that
Help would be apreciated, thanks

no usb drive plugged...
(and the fan also start sometimes without the ac adapter)

IS GTX 970 GAMING 4G compatible with MSI B75A-G43 ?

So i bought myself today this card GTX 970 GAMING 4G
When i went home to install it i found out that it does not work. the fans spool up, the msi logo lights up, but no picture on monitors, not even the bios screen. i managed to boot up with the ntegrated graphics, GTX does not show up in device manager. Motherboard bios is up to date with the last bios version from the boards support/dovnload page version 10.10
Motherboard: B75A-G43
PSU: Corsair CX750T
My question, are the graphics card and motherboard compatible, did i get a bad card or do i need a new motherboard.

The warranty guys did check the card out and confirmed that it was dead on arrival. So they replaced the card and i had them check first if the new one works. It did so now it's waiting until evening for some gaming action

MSI B75A-G43 runs fans at full speed for 1-2 seconds after powering on the PC
