Share Facebook Report 2 Answers Voted Oldest Recent Anonymous Added an answer on June 12, 2019 at 6:03 pm It depends on what sort of noise it is, try blowing on the fan to dust it (or using a duster/vacuum cleaner if it’s caked with dust that can’t be removed through blowing). If the noise persists I would say take it to the place you got it and see if they can do anything, or contact the manufacturer and see what they say. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on Google plus Share on WhatsApp Mickeymouse Added an answer on June 12, 2019 at 6:02 pm Probably dust in the fan, possibly something loose and vibrating. While your computer is turned off – remove the side panel and vacuum thoroughly – especially parts that move (cpu fan, video card fan, and the power supply fan). Try to use an end piece on the vacuum nozzle, you don’t want to touch the metal to your computer in case of a shock. If you have trouble vacuuming…. try getting a bottle of compressed air from any computer or hardware store and blow it out. If the fans seize from dust (and they eventually will) your computer will overheat. Thats bad. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on Google plus Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
