ANV15-51-URGENT request to fix GPU fan issue in acer nitro v15

Hi Acer Community,

I'm facing a persistent issue with my Acer Nitro V ANV15-51 laptop (purchased in October 2023).
Here are my system specs:

Model: Acer Nitro V ANV15-51
CPU: Intel Core i5-13420H
GPU: NVIDIA RTX 4050 (6GB VRAM)
RAM: 16GB DDR5
BIOS Version: InsydeH2O v1.31 (27-06-2025)
OS: Windows 11 Home

Issue:

While using the laptop (even during light usage), the fans suddenly spin at maximum speed and stay that way permanently — even when temperatures are low. The only way to stop it is by putting the system to sleep or shutting it down.

After turning the system back on, the fans again behave oddly: they spin high at boot, slow down briefly, then go back to max speed and stay there.

This started happening after BIOS v1.26 update, and I'm currently on v1.31, but the issue still persists. I’ve tried:

Cleaning fan vents and inside (hardware is fine)
Updating and reinstalling NitroSense
Third-party fan control apps (none detect fan properly)
Resetting BIOS settings
Checking for malware / thermal issues (everything is normal)

Questions:

Is Acer aware of this fan issue introduced in v1.26+?
Will there be a fix via BIOS or EC firmware update soon?
Is there any way to officially rollback to BIOS v1.25 to resolve this?

This is impacting daily usability and fan noise is unbearable. Any help or update from the Acer support/dev team would be appreciated.

Thanks in advance!

You need to change Advanced power settings and also the cpu/gpu paste and vram putty regularly in this laptop, as the problem you are experiencing is common.

Use Thermal Grizzly pastes for best thermal efficiency (I've done all this to my Nitro AN515-56 and it works perfectly) and if you do allot of gaming especially with the ANV15-51 model, its essential that you change the cpu/gpu paste every 3-4 months for bets thermal results, if you don't every 12 months, and also buy a multi fan tablet cooler like the very reasonably priced and excellent Thermaltake Massive 12 Max Notebook Cooler.

Conductonaut Extreme liquid metal for the CPU and the GPU if you want, but be sure to only use a very thin layer of this paste, as its conductive and if it spills underneath the cpu or gpu or onto the mobo it will short components.
Kryonaut Extreme for the GPU
TG Putty for the VRAM chips

Then go to the below settings Control Panel > Hardware and Sound > Power Options > Edit power plan > Change advanced power settings < and you will see the below windows > then reduce "processor max and min power settings" and see if that reduces temps also, do the same for the Graphics settings.

press battery reset pin for 30 secs

i already did, but the gpu fan is still ramping at max speed. Please Acer fix this issue asap

can i have the seria#

Hey brother, It is an error from the side of Acer, probably from the BIOS ver1.26+, they still haven't fixed it. All we can do is wait.

Please do tell if you found any fix

I carefully opened my laptop (since it’s already out of warranty) and disconnected the GPU fan cable, so now the laptop only runs on the CPU fan. I did this because I don’t play games and mainly use the laptop for coding and studying. For my usage, a single CPU fan provides sufficient cooling.

Since both fans are on the same side and share the same copper heat pipe, I decided to disconnect the GPU fan and rely only on the CPU fan. After a few days, I reconnected the GPU fan to test again, and for a few hours, it behaved normally. I thought the problem was fixed, but after some usage, it went back to running at maximum speed. So, I disconnected the GPU fan cable again.

I plan to reconnect it when the next BIOS update is released, hoping Acer resolves this issue by then. 😔

Yes, brother. I have tried this fix. But since my laptop has software that takes heavy usage of cpu and gpu, like editing videos, it displayed windows blue screen error and gpu throttle issue. SO, I put it back and let it spin at max speed.

I just wear headphones and the noise feels less, though my roommates are fed up of me, but they've been habituated as well. And looks like acer isn't rolling any updates till a month or more, since this issue has been going on from a long time.

Hope the best for you.

tusar003

yeah, thats good for you. All we can do it waiting for next bios update.

try performance mode but with auto only it may not be instant but after few reboots it should revert idk why it does that

tusar003

@Sasmit_Singh1 So how is your laptop doing? is the problem totally solved?, btw i'll try your method as well.

Hi tusar003,

If all methods to slow down the fan speed fail, you can try disabling the Processor performance boost mode in Advanced Power settings. This prevents the CPU from boosting above its base clock, which can reduce heat and fan noise (though it may lower peak performance).

1. Change the setting in Power Options

Open Control Panel → Power Options.
Click Change plan settings for your active plan.
Click Change advanced power settings.
Expand Processor power management → Processor performance boost mode.
Set On battery and Plugged in to Disabled (or another mode you prefer).
Click Apply → OK.

Mode descriptions for reference

Disabled – CPU will not use turbo boost; runs at base frequency only.
Enabled – Allows turbo boost when needed.
Aggressive – Boosts quickly and sustains higher clocks longer.
Efficient Aggressive – Boosts quickly but drops sooner to save power.
Efficient Enabled – Boosts moderately with more focus on efficiency.

If the option is missing

Sometimes Processor performance boost mode is hidden by default. You can unhide it via the Registry:

Press Win + R, type regedit, and press Enter.
Navigate to:

Code

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7

In the right pane, double‑click Attributes.
Change the value from 1 to 2 (Hexadecimal).
Click OK, close Registry Editor, and re‑check Power Options — the setting should now appear.
