Hi ,

I have a strange thing going on with the fan, it makes a loud noise when the laptop is at cool temperature.

Other strange thing is when i open a demanding app like games, the laptop starts to be hotter of course and the fan became to her normal sound. when i close the game, the laptop gets cooler and the noise of the fan cameback.
i opened the laptop and i cleaned the components, such as the fan, and nothing has changed.
since the temperature is low i dont think i have to change the thermal paste in the cpu and the gpu.

tldr; loud strange noise of fan when laptop is cool, and a normal sound while opening a demanding app.
