I have an Asus Vivobook S410, the one with i5 8250u, 8GB RAM, nvidia MX150
i bought this back at december 2017. my problem right now is that my fan sometimes make a buzz sound when i started the laptop, when i open it to see what caused the sound.. it turns out the cpu fan turns on and off, the buzz sound comes from when the fan stops.
Sometimes the fan starts spinning and then theres a continuous buzzing sound and whenever i play a game, the game lags so bad.
From what i found so far, its not because of dust since cleaning it doesnt help, its not because of some cable entangled to the fan, and also i think its not because of the temperature ?
Since i feel the heat is the same from back when i bought this laptop. i tried to pull out the cpu fan and see how it goes, and then eventhough i feel the same heat, the game lags even more like only 5 fps... im at a loss of what to do right now.. should i replace the fan ? if it is, its going to be hard since so far i cant find any online on my country
