Fan running on mac laptop

These vents draw in cool air and expel hot air. If you block these vents by resting your laptop on a lap, couch cushion, pillow, bed or blanket, then your Mac is sure to heat up quick. I use a coffee table book to keep my MacBook Pro's vents unobstructed when sitting on a couch or lying in bed. If it looks like a bunch of grime has collected along the vents, you can try blowing it away with a can of compressed air. Of course, you run the risk of just blowing the debris further into your Mac.

If that appears to be the case, then you will need to open up your Mac to get under the hood. Get yourself a tiny Phillips-head screwdriver and you can remove the bottom panel of your MacBook to clean out any dirt, dust and grime that may have collected over the years.

Getting Start With Macs Fan Control

Use your can of compressed air to blow away any debris or a lint-free cloth to wipe it away. Pay particular attention to the cooling fan itself and its vents, along with the entire back edge of your MacBook. The goal here is clean passageways for maximum airflow.

There is a chance that the reason your MacBook is overheating is there's something wrong with the cooling fan itself.

How to deal with a loud MacBook fan

None of these really work, but the solution is very simple. Since laptop users are mobile, they're frequently using different printers. When sending a document to print sometimes my MacBook selects the wrong printer, when it doesn't print I select a new printer and print again. But I forgot to delete the print job sent to the first printer, so my Mac keeps looking to print at the other printer causing the processor to heat up and the fan runs constantly.

The laptop will stay quiet and cool, the battery will last the usual amount of time, and MacBook mobile life is good again. One fix for an always-running laptop fan 12 comments Create New Account.
