CPU Fan Generating More Noise After Windows 8.1 Update

    CPU Fan Generating More Noise After Windows 8.1 Update


    Windows 8.1 was initially supposed to be a bug-free operating system that shouldn’t cause too many problems to its first adopters. At least, not so many as Windows 8.

    It turns however that many of the users who decided to make the move to Windows 8.1 are actually experiencing all kinds of issues, including a higher noise level coming from the CPU fan.

    Consumers who have turned to Microsoft’s Community forums to report the bug explain that the CPU fan is generating more noise than before, most likely in an attempt to cool the processor. This means that Windows 8.1 is actually requiring more CPU power, hence a temperature increase and the need for more intense cooling.

    Here’s what one of the users has posted on the forums:

    “My laptop is a Sony VAIO and is less than 1 year old. I am referring to fan sound, I had no problem before the update to Windows 8. I called Sony and they told me to contact Microsoft. I noticed my laptop too hot on the side where the fan sound comes.

    “I am not using my laptop on a flat surface, I usually use a little piece of wood in the back to have a 30 degree angle. The fan stop if I restart the laptop, couple minutes after, it started again at full power. When I explained this to SONY, they told me to contact Microsoft immediately, there's nothing wrong with the machine.”

    At this point, no workaround seems to be available, but as far as users are concerned, there’s not much that can be done since Windows 8.1 requires more CPU power.

    My laptop i7 first gen 820 has been less heat and fan noise since windows 8 and 8.1.

    I'm happy I don't have that problem.

    Have you checked to see if there is a BIOS update for your PC? I had a somewhat of a similar issue when I installed 8 on my Samsung laptop, it just didn't run right. I checked for a BIOS updat and there wasn't one....6 months later there was so flashed the BIOS, installed 8 and it's been working great ever since. Worth checking into.

    Nah... I'm just gonna format and roll back, probably to 8.0... maybe back to 7. Won't be for a bit tho, as I got stuff to do...., switching to electric heat and dumping the oil furnace...

    After a bios update to my Asus motherboard my i5 is running much cooler under 8.1 than 8, like 10+ degrees cooler, especially with speedstep enabled and even under turbo conditions. And the OS itself is faster. The improvement came after the bios and chipset drivers updates. This is my experience.

    I dunno...without a good OS my computer might make a good planter, or serve as a doorstop, maybe... Albeit, an expensive doorstop. You really can't have one without the other...

    As is evident in this thread (aside from the fact that sensible people should avoid laptops whenever possible--desktops are much better, and much better buys), when moving to a new OS it is generally profitable to check with your manufacturer for a bios update whether you own a laptop or a desktop, since bios updates frequently accompany a new Windows OS. (For obvious reasons.)

    In fact, it generally pays to keep your machine bios or UEFI updated regularly, new OS or not. Just a thought. Bios/UEFI updates contain bug fixes and new feature support, just like regular software updates.

    Ok, hold everything..... I think I found a "fix".

    Taken from this page..... CPU doesn't drop below 30% in idle after update to 8.1 - Microsoft Community

    This bit in particular.....
    Instead of renaming the sdclt.exe try this: - Go to Scheduled Tasks
    - Microsoft -> Windows -> Windows Backup
    - Disable the "ConfigNotification" Task (or anything you find here)


    That should do the trick for the Windows Backup problem.


    Also if the system log has a lot of DCOM errors it is possible to fix this. I dont have a link now but there is a example how to do it in some forum. Easy to find if you google for the CLSIDs.



    This 'seems' to have worked for me.(so far) I have cyberfox open, at least 25 tabs open. I have xyplorer open. I have media player classic open, playing a tv epp.
    Speccy reporting about 15c.....

    I can now add that 5 hours later, the cpu temp hasn't really budged, so if you're experiencing this issue, this seems to be the fix.
