So, for few months now, my fan is producing so loud wierd sound it makes me crazy, sometimes I'm scared it'll blow. Last night I've opened my lap, everything in parts, took motherboard off, then fan, opened fan and there was no dust in it.
I'm sure it's fan cause when I put everything back on, i didnt closed it with final peace to see when I turn my lap on what produces sound - fan or hdd, and it was fan. When you turn it on fan runs for few secs, and in that time the sound was coming from fan, as soon as it stopped the sound dissapeared.
Any suggestions?
