 Hello Thomas,

This issue has been driving me nutz for the last few days, until now. It has been over an hour and no fan and lag.

Thank you for your posted solution !!!

This is for all the people who upgraded to windows 11.  My computer was freezing quite often.  I sent it in for service and the motherboard was replaced.  Got it back and a month later, the same issue.  I decided to delete windows 11 and install windows 10 to it's original setting.  It is working great now and has been for the last two weeks.  I would try that before I sent the laptop back for repairs

My Dell Inspiron freezes many times and fan runs on full speed. Anybody suggest some remedy for this issue.

Thanks for posting the solution :)

Thanks for the easy instructions, but it didn't work for me.  I still get the fan spin-up & freeze.

I have this problem too.
