But when it is at high speed, the buzzing sound is gone. I think the noise got masked when the laptop fan rotates at high speed. The sound still continues after i open the laptop and clean the fan. I owned the laptop for 2 years. <br /><br />Any idea what is causing the noise? Should I replace the fan with a new one? <br /> emeraldgiant888 Technical Support Wed, 01 Apr 2020 17:15:47 +0800
