Question - PC Fans running at high speed after fresh windows install | Tom's Hardware Forum
October 17, 2023 - Click to expand... The high temps you're experiencing explain it all. You need to get your temps down for the pump fan to stop running at full throttle. I'd start with cleaning out the dust bunnies in there and see what happens.

What to do when your CPU Fan runs at full speed always?
If the CPU fan runs at full speed all the time, there might be something wrong with the processor or the sensor (in the fan). It can also be an issue with the heat sink on the processor.

Stop What’s Revving Your CPU Fan Constantly in Windows 10
July 14, 2021 - I don’t normally power off my machines, but the fans kicking on full at 3am motivated me to turn my machine off at night. A clean install of bloatware-free Windows 10 stopped this behavior. Presumably, Lenovo services were responsible. ... I found that Dell Support Assist was making my fan run after about 5 minutes of use I have programs where I can stop the fan turn down every setting available to anyone, But I have uninstalled Dell support assistant and it now is back to normal, took me a few days to figure it out but yes it stopped my issue.

Laptop fan is running constantly or loud under Windows 10
May 20, 2018 - Most causes of the Laptop fan running constantly can be traced down to high CPU utilization caused by Windows updates or other applications. When CPU utilization runs high the CPU gets warm and the fan will run to control the thermal temperature of the CPU.

r/pchelp on Reddit: HELP my CPU fans are running at full speed even though my cpu is not hot
March 16, 2024 -

I'm literally so desperate. As soon as i start my PC, the CPU fans are freaking out. Core temp and bios say cpu temp is about 30°C and i have set the "silent" fan profile. But for someone me reason both my cpu fans sre running at 2000+ RPM. I have reset the bios already and i have no idea now what could be happening. And my pc is so LOUD. I built it myself only a few months ago and it's been fine until now, this just started yesterday. CPU is an i5 13600k, asus rog strix B-760-F mobo.... (the other cha fans are controlled seperately in case you were wondering. There are like 6 of them)

As such, the fan error occurs before Windows 10 OS boots and is probably caused due to some hardware issue, and It may not be due to overheating. The most common reason a CPU fan runs at full speed is that its sensor is not functioning properly.

How to Troubleshoot Fan Issues | Dell US
1 week ago - If the hardware test passes, go to the next step to try to resolve the fan issue. See the Dell knowledge base article Reference Table of ePSA, PSA Error Codes, and Troubleshooting Steps (2000-0NNN Series) for information about how to look up the error code for additional help. Diagnostic Tip: There is no dynamic control available during the ePSA tests — the processor runs at full speed during these tests, and the fans will likely go to high speed throughout the testing.
