G750JH - Left fan really noisy

Hi,
I have my left fan of my asus rog g750jh going almost full throttle when i do nothing on my computer.
Graphic card temperature is about 41°, cpu at idle (14% usage) but the fan is really noisy...

It has been fully cleaned yesterday, so no dust in the fans

the blown air is not hot, the right fan is silent.

Could you help me please ?

Noisy as in just louder because its running at full speed or noisy as in it shouldn't sound like this no matter what?

If its the latter plan on fan replacement, your bearings are shot.

Hi,
it's noisy because it's running at full speed, and it should not as the computer is not doing anything...

Download HWiNFO and check, what is your CPU temperature, and how fast your fan is spinning.

Post the screenshot, if you can. Might be, that something is using your CPU at idle.

Open task manager and see whats running and loading it down. 40% CPU is not idle.

Yup,
sometimes it goes to 1-2% sometimes 40%
and nothing special in the task manager...
