Updated to .3 yesterday from .2 ( i assume - generally keep current ) and have been hearing my fans kick on high ALOT, used to be relatively quite. Especially bad at boot for a while and than just randomly many times through out the day. I have not changed any of my work flows or patterns nor added any software. Ive even switched from Outlook client to web version. Anyone else experience this ? I have not tried resetting my SMC etc .. that my next step if it doesnt stop ..
Ran Diags came back clean , Resetting the SMC this AM seems to have resolved the issue all has been quite so far .
Thank you for your informative reply, DUlrich1277,
You might like to read this article about kernel task from Apple:
(Might also be worth checking out the link to Activity monitor, contained therein)
You are doing well in the hunt for a solution.
Seems a good idea to try a reset ... sorry I'm no expert with servers / drivers ... may just need an update to latest version(s).
Big Sur cannot tolerate anything less than 64-bit apps ...
... guess you would have checked for 32-bit apps before you updated your OS.
If need be, wonder if running Diagnostics (to check for hardware issues) would reveal anything pertinent ?
All the best :)
Loud fans are not a problem. They are a symptom of some other problem, such as an overloaded CPU, excess energy consumption, or some other kind of hardware problem.
no changes to make CPU overloaded .. and did not happen until this update .. so the update caused a hardware problem ?
Big Sur was a Major! upgrade, and seemed to me to be quite hefty in size.
You might want to check that your memory / storage is coping ok.

Hope this helps you find the source of the situation :)
thanks 1.86 TB free of 2TB , memory is good to .. it seems its windowserver is the CPU hog as well as kernel_task at times .. but not doing anything intensive .. almost feel like maybe bad driver for the video card? (AMD Radeon Pro5500M 8GB) just strange started all of the sudden after that update .. ..
yea which is is that window server task .. which i looked into .. i have no malware or any thing odd.. which leads me to maybe a bad graphics driver .. ill think ill reset the SMC and NRAM/PRAM items and see if it helps .. just driving me nuts and only since the last update
thank you for that link was looking for something like that ..
You're welcome :)
Glad to hear your efforts met with success,.Seems you have solved the issue!
Thank you very much for letting me know :)
