Fans reducing the battery life .

I have been using Nitro 5 515-43 for a month now and I have noticed that when fans are at 0RPM I am getting a whopping 8-9hr of battery (usually watching moves / cpu temp 36-38)
But while Iam browsing or watching YouTube
I get like 4 hours of battery back up (2000RPM) so here is the problem
While I browes the temps are actually below 40 (the temp where the fans kick in )
But there is a spike in temp usually while loading the webpage it goes to 40-41 for like a second .....FOR A SECOND !!!!! And back to normal (38°c) but the fans don't back off untill it stays below (40°c) for some time.
But there goes another spike in temp and the fans never stop even at 37-38°c because it hits 40 for a SECOND ...

is there any way I can make the fans turn on when the temps are at 42 °c insted of 40°c (like 2000rpm doest cool **** mostly the heat is localised at the cpu area and the heat never reaches the heat sink )

Or a way to just turn of the fans when below 40 insted of waiting it to maintain temps below 40....

I suggest you check this temperature table:

Also, can you inform the version of the bios? Have you also set up fans on nitro sense? In addition, I will invite colleague @batmalin, because I think he got a similar problem in another model.

Mines GTX 1650....that stays at constant 40 although the usage is 0%..

See at 40 °c fans kick in. ..I want that to be like 42° .

There is no official way to change that, only with BIOS unlock mod(you have to use programmer to dump the BIOS, unlock it and then flash it back) or you can try NBFC and play with the presets. Other that that I can`t think of anything else besides to ask Acer support for unlocked BIOS (good luck).

Does anybody has a preset for acer nitro 5 515 43 for nbfc..
I installed it and used the acer predator once and it kinda worked ( like I can turn the fans off immediately when temps where below 40 ...but the temperature threshold is not working.
