Hello Community!

PROBLEM DESCRIPTION:
I have a problem with my Acer Aspire V5-561G: The fan is not working. The fan is not spinning at all thus the CPU is overheating. In normal use CPU temperature fluctuate between 62° to 85°, if I stress the laptop performances for example by running a game, temperature quickly raise sometimes even up to 100° and the laptop suddenly die (completely shoutdown).
I am running Windows 10 and performed all the latest updates (20H2), I had the same problem even before updating btw.
I updated BIOS to latest version: 2.17
During last 2 days I made extensive searches on internet looking for a solution, I tried to install several fan speed softwares (but on this laptop model, you cannot control fan speed from those softwares), several HW monitor software and Acer Quick Access (that on this laptop, do not allow you to use CoolBoost).
During all those tests, at a certain point my fan stated working correctly ! (So please note that the fan is NOT phisically broken) and I used my laptop for several hours with the fan correctly cooling well my CPU. Unfortunately I wasn't able to correlate any of my test with this success (as long as I remember, fan do not start to work immediately after any o my tests but after many, and a reboot), I thought I completely solved this issue somehow but when the day after I turned on my laptop again, the fan was still not working. I tried to re-install the same softwares I tested but none restored my fan functionality again.

I grown the impression that the issue is somehow related to "Acer's bios embedded fan managment" (I don't know how to phrase this well, I hope you got it) but I really cannot find a stable solution myseld.

Appreciate any suggestion!

    Adding a few more notes:
    - My fan is not spinning at laptop power-on. I read someone stating that fan should always spin at power-on, mine is not.
    - As a workaround I bought an external Cooling Pad, it works and it manage to keep temperature lower than 100°, using it I can play games without the 'laptop die' problem. But as said, this is hust a workaround... I would like my original laptop fan to work (PS. When the fan worked, temp were better than using the cooling pad).
    - Softwares tested as long as I can remember:
    * Acer Quick Access --> No CoolBooster option on my laptop
    * SpeedFan (SOKNO)
    * ACFanControl
    * OpenHardwareMonitor
    * HWiNFO
    * Fan Speed by Dotshoot
    * RW-Everything
    * NoteBookFanControl.1.6.3

    The fan is normally controlled by the BIOS using these stats:
    Note that it's not turned on until the CPU temperature gets to 48C or the GPU gets to 80C. What temperatures are you seeing? Your thermal grease might be getting old, the fan might be getting blocked up with dust, the heat sink might be getting blocked up with dust...

    Hello Billsey, thank you for the answer. Mu CPU temperature is between 62C and 90C in idle state and the fan is not spinning.
    I opened the laptop and it's perfectly clean (Including fan and heating sink), no dust at all. Just in case I cleaned it again with air compressed and vacuum cleaner. I do not check the thermal grease, you're right, it's probably old but yet it's not the explanation of why my an is not spinnging (Keep in mind that when it worked 2 days ago, temperatures were perfectly in the expected range).

    Well, it shouldn't be too tough to replace the fan at this point to see if that is the issue. The Acer part number for the CPU fan is: 23.M8EN2.001, you can search on that or just look for an equivalent.
