Even in Low temperature GPU Fans spinning nonstop

I am using acer nitro V15 with

Intel Core i5- 13th Gen 13420H processor, NVIDIA GeForce RTX 4050-6 GB GDDR6(16GB DDR5/512GB)

3 to 4months back the fan suddenly started to spin very fast when i switched the laptop on and it didnt stop even when doing basic works, so i gave it to service centre they told me that it didnt have any problem and suggested to to a basic laptop cleaning service and they even changed the thermal paste…its been 3 to 4 months the laptop has been working gud..but from yesterday the gpu fan started spinning again even though the temp is under 45 degree and it doent even stop the whole time…plzz suggest something..What should i do? ( i have updated nvidia drives and also normal windows update) the fan is in auto mod, even if i try to change it tocustom and limit the fan speed it doesnt decrease its rpm

Hi Trezzy,

Thanks for the details. Since your Nitro V15 is running an Intel Core i5-13420H and RTX 4050, and the GPU fan is spinning nonstop even at low temps, here are a few steps that may help stabilize fan behavior:

1. Update BIOS Visit Acer’s support site and install the latest BIOS version for your Nitro V15. This can resolve thermal control bugs and improve fan curve logic.

2. Upgrade to Windows 11 24H2 If you haven’t already, update to the latest 24H2 build. Some fan control issues were addressed in recent cumulative updates.

3. Power plan alignment

In NitroSense: Select the Balanced power profile
In Windows: Go to Settings → System → Power & battery → Set Best power efficiency mode

4. Disable processor boost behavior

Open Control Panel → Power Options → Change plan settings → Advanced power settings
Under “Processor power management,” set Processor performance boost mode to Disabled for both battery and plugged-in→ This helps prevent unnecessary CPU boost spikes that can trigger fan ramp-ups (see image for reference)
