New PC Fan Constantly Blows During Use of PC

[LP4800]

I purchased PC in March 2022and from the start I've heard the fan blowing while I am using the PC.  I 've had several troubleshooting sessions with HP and nothing has helped.  I'm now with the 3rd session being told to do a "cloud recovery" of my system (which would be like deleting everything I've done on the pc in the past couple of months).  I am told that this is due to 3rd party applications on my pc - and the only 3rd party applications on my pc, other than those it came with, are internet security software and backup software (that I added).  How can a new pc not be able to handle two new 3rd party applications?  I have 10x that on my older pc and never in the 9 years I've had it have ai heard the fan blowing?  Anybody else experience anything similar to this?

Power up the system, press ESC or F10 and get into the BIOS setup.

Is the fan spinning at high speed?  Wait a few minutes and see if the fan picks up speed.

If the fan works OK when in bios but runs like crazy in windows something has told it to speed up.  It could well be overheating even system is idle.  I suspect you have an i5 cpu like this one.  It is supposed to run at 2.4 but turbo speed is 4.2

After booting into windows immediately put your hand or better your cheek next to the exhaust and see if it gets warm and then cools down after the fan starts spinning.

If there is warm air coming out you may be running in turbo mode all the time.  In any event try the following to see if it helps

Enter "power" into the windows search bar and select "edit power plan" then click "change advanced power setting" and scroll down and expand "Processor Power Management".  Mine shows 5 and 100 for min and max respectively.  Change yours to 0% and %50  That will force the CPU to never go past 2.4 speed.

If your display showed %100 and %100 then it is forced to turbo speed all the time and will quickly overheat.

If the %0 and %50 helps then try raising the %50 up and see if the fan behaves.  I have found that %95 maximum keeps the CPU out of the very highest speed multiplier.

If this works ok (fan behaves) but your computer games run too slow then post back here as there is something else that can be done

[edit]  Please download CPUz and GPUz 

CPUz will show the speed your CPU is actually running at and GPUz can show temperatures of the CPU and GPU.  It is possible the FAN is running at high speed due to combination of several things heating up.

Hello,

Did all of the BIO troubleshooting/testing with the HP reps (three times), passed all the fan tests, etc. -  everything was normal.  So, as you suggested, I changed the processor power management to 0% and 50% (it was previously 5% and 100%).  I did that last night and have not heard the fan since (I was on the computer for a couple hours last night and have been on for about 1-1/2 hours today and it's still quiet).  I don't game, so should I still try to raise the 50%, or just leave it?  

Thank you!!

Setting the max to %95 will keep the CPU out of the top multiplier.  That worked perfectly on a number of Xeon systems I have. 

Try lower values if you still have problems.

Great - thank you!
