Title:
GPU Fan Issue After BIOS v1.26 – Acer Nitro ANV15-51

Body:

Hello Acer Team and Community,

After updating my Nitro ANV15-51 to BIOS version v1.26 (dated 21-03-2025), my GPU fan behavior has become erratic.

Even when the system is idle, or running on Integrated Graphics only, the GPU fan suddenly ramps up to high speed and then slows down — this happens in a loop.

What I’ve Tried:

BIOS Reset to Defaults

EC Reset (battery drain method)

Predator Sense uninstall/reinstall

iGPU-only mode

Windows Reset (Reset This PC)

Disabled NVIDIA background services

Still, the fan behaves wildly and Predator Sense is unable to control it in any mode. Also, the BIOS has no thermal or fan-related options.

Acer support has denied downgrade to v1.25, and no fix has been provided yet. This clearly seems to be an EC firmware bug introduced in BIOS v1.26.

My Request:

Please escalate this to the firmware/BIOS engineering team and release a fix (BIOS v1.27 or EC firmware update). The fan control is broken and affecting usability.

Model: Nitro ANV15-51
BIOS Version: v1.26
Serial Number: UNQN8SI001XXXXXXXXXXXX

I’ve attached a full PDF report that I also sent to Acer support.

Thanks.
