New laptop fan always on

[szymonm2]

My laptop fan is always on (80%)
The laptop fan doesnt want to turn off even if there is nothing running.
The fan is really loud on boot and turns off 30mins after startup.
The laptop is 4 weeks old.
The laptop model: msi ge70 onc
I did a scan with avast,malware bytes,hitman pro,tdsskiller they didnt show any virus.
The fan is sooo sensitive that when I open firefox the fan goes to 100%
My battery life lasts for 1-2h no wonder why....

Ps: All the time the fan releases cold air. What should I do?

Sorry for the bad quality because my internet upload speed is very slow.

You get 1-2h battery life because it's a gaming laptop with a 17.3" screen. That's common across all gaming laptops.

Cold air is good also, btw: it means your system isn't getting hot.

You should be able to control the fan with the hotkeys or other software. It's probably revving high in Firefox because Firefox uses hardware acceleration.
