Acer TravelMate p215-53G-51MU fan stops running while doing minimal task

TMP215USER

Hello, I use an Acer travel Mate P215-53G-51MU, its got an 1135G7 intel i5 Processor along with the Nvidia MX330 Graphics card, I am running the latest update of Windows 11 at the time of writing this post. Normally the machine works just fine but i have noticed that when my battery is below 30% and I am doing minimal tasks like watching a movie on a streaming site or reading a pdf my cooling fan stops. completely!

To be fair I like this and would like for it to happen at all times when i am doing minimum tasks but that is not the case, when ever the laptop has power above 30% the fan keeps spinning and at some point it blows cool air. I can understand how this maybe a safety feature but does it not waste power? My battery barely hits the 4hr mark while doing close to nothing because the fan is always spinning. I must also indicate that it runs silent enough you wont even notice it when the audio is playing.

I am an efficiency freak and would like to have some control over the fan in situations when I am barely pushing my system. Please advice on what I can do for my particular case?? I have cleaned my laptop to ensure smooth air flow, I always run my pc on a cooling pad, but that doesn't help. I did some searching online and apparently my system doesn't have a particular module to control fan speed so i think windows maintains that some how using CPU temperature, I am not really sure about how it all works but, I've been through the bios and there is also nothing that can remedy this issue.

Also I run my system with everything set to maximum efficiency plus battery saver is set to be on every time I disconnect from the power supply, but that also doesn't keep the fan off long enough. is there something that can be done? The high performance GPU is always off unless i am doing some video editing in which case i am fine with fan going wild. and yes the machine is new,

If you haven't installed Acer Quick Access download version 3.00.3052 from Acer Support for your laptop model and open it:

Click on System Usage Mode and enable Silent Mode instead of Performance Mode that will reduce the fan speed. Also Balanced Power Plan instead of Best Performance Plan will reduce the fan speed. Don't let the battery go below 50% charge as this throttles power to the CPU-GPU to conserve battery power and keep the power adapter plugged in 24/7 so the battery is always 100% charged. Don't use Acer Care Center 80% battery charge limiter and uninstall all bloatware and pre-installed programs as most of these apps run at the background using your resources, networking bandwidth and cause the laptop to get hot.

For your system this is the fan speed table:

It's possible the fan is quiet enough at 2800 RPM to be thought to be off. I don't think Windows will shut it all the way off to conserve battery… There have been a bunch of BIOS updates for your model over the years. Which version are you running?
