u430 rubs sound

2016-01-19, 13:27 PM

Hi Everyone.


Recently my laptop lenovo U430 makes a noise when in use, particulary when i do something like see a movie or games or when it's started...., it seems that the fan make a rubbing noise. Is there a way to settle the problem?


Is this a hardware fault or normal behaviour? From my experience this sound seems a bit excessive.


Thanks you very much,

Welcome to the Lenovo Community !


Try using some compressed air to blow out all the vents.  Possibly there is a build up of dust and debris on the fan's blades which is causing the excess noise.  Cans of compressed air can be purchased at any store with an electronics department or at an office supply store.  When using the compressed air just use short bursts as prolonged blasts of air may damage the fan.  Blow the compressed air into each vent several times or until you can no longer see dust or debris being blown out.
