How to Fix a Laptop Fan Making Weird Buzzing or Grinding … - dell fan grinding sound - Dell Community
Recently I have noticed a very loud and grinding noise coming from the left side of the laptop, after removing the back cover and blowing out dust, It seems to be the CPU fan. The noise seems to be related to the bearing, it just seems to be at low rpm, although the sound of the fans under load may be covering up the bearing noise.Here are six steps that could help to balance a wobbly or noisy ceiling fan: 1 You should completely shut the ceiling fan off, even on the home panel or electric circuit as you have to bring the blades down. It may require for you to touch some or a few wirings and so it's safer to do this step. 2 Take the blades off carefully.
