Acer Nitro ANV15-51-GPU fan randomly speeds up and slows down even when the temperature stays normal (around 40–60°C).

Hello everyone,

I’m using an Acer Nitro V15 (model ANV15-51) with an NVIDIA GeForce RTX 3050 (6GB) GPU.

Recently, I noticed that my GPU fan randomly speeds up and slows down even when the temperature stays normal (around 40–60°C). The CPU fan works perfectly fine — only the GPU fan behaves unpredictably.

I tried the following steps but the issue still persists:

Tried reinstalling Nitro Sense and updating NVIDIA drivers.

GPU fan control is locked in Nitro Sense (can’t manually adjust it).

Is this a known issue with the Nitro V15 series?

Also bios is up to date like v1.31

Any help or suggestions would be greatly appreciated!

Thank you 🙏

It’s actually pretty normal for the GPU fan on the Nitro V15 to change speed even when temps look stable. The fan curve on these models reacts not only to the temperature but also to small power or load changes in the GPU, which can cause quick RPM jumps.

Since your BIOS and drivers are already up to date, I’d recommend doing a clean reinstall of Nitro Sense (uninstall, reboot, and reinstall from Acer’s support page). After that, check if the fan behavior changes in Auto Mode. You can also use tools like HWMonitor or MSI Afterburner just to verify that fan speed and temperature readings match.

If the fan keeps fluctuating wildly (like revving up every few seconds for no reason), it could be a firmware tuning issue — in that case, it’s worth reporting to Acer Support so they can check if there’s a newer fan control profile for your BIOS.
