Laptop Fan running at 96% all the time

HP Recommended
HP ProBook 440 G5
Microsoft Windows 10 (64-bit)

Hello everyone!


I recently changed my original 256 GB NVMe M.2 Hynix with a 500 GB NVMe M.2 Samsung SSD. After that change, my assumption, something happend with my laptop FAN. It got stuck at 96% all the time (I got this procentage by searching in the BIOS).


I did all the solutions said by HP Official Support page for FAN problems such as cleaning, checking for updates (Windows and BIOS), I even restarted my laptop at factory settings, I changed the SSD with the old one (before I had the problem) and it still didn't work. Everthing is up to dated - I have the latest BIOS updates and Windows updates. The first second I boot up the laptop, the FAN starts *screaming*. There are no backgroud processes or anything at all. It's a permanent noise.


Please help, this is getting very annoying! 😞


Thank you!

Several different issues are at work here,


First, it is not unusual for the fans in a laptop to SPIN UP when the laptop is first turned on, run fast for a few seconds, and then quiet down.  Yeah, it is annoying but you get used to it.


Second, you said there are no background processes running but with Windows 10, this is most definitely NOT the case. My current PC, on which ALL I am doing is typing in this window, is running 170 processes -- of which nearly 100 are running in the background.  Win10 needs LOTS of processes just to function, so claiming there are none running makes no sense. Do a Services list and sort by  status.  You'll see pages and pages of running tasks.


The newer Elitebooks are more compact and pack in a lot more processing power and components that the older, bigger, heavier laptops.  There is simply more heat generated and less place for it to go -- and that puts more pressure on the fans.


If you want to investigate disabling tasks to reduce the processor load, which will also reduce the heat, which will then quiet down the fans, then look online for Black Vipers Tuning Options for Windows 10.  I have used that on my PCs and I was able to reduce the processor load to down under 4% nearly all the time and barely hear the fans.
