Do I ever need to clean the vents on my MacBook Pro 2019? If so, how?

I was finally able to stop the very loud running of the computer by restarting it twice. Everything seems fine now. When it was running loud, I looked at the utilities and nothing seemed to be using too much power. But again, it's fine now.


But how do I ever need to clean the vents?


If so, how?

Good morning!


If your Macbook Pro has a 14-inch or larger screen, the air intakes are on the sides between the bottom plate and the chassis. You can look in the vents with a bright light but I doubt anything will show up.


If the vents look clogged, never use "canned air." The propellant in canned air is a compressed liquid. If you shake the can or hold it any way other than bolt upright, some of the propellant will eject and form frost on the internals. That quickly turns to water, seriously compromising the computer, and tripping moisture sensors inside the computer. When those sensors are tripped, Apple may refuse to service the device.


A soft, non-static brush is my go-to for computer cleaning. I get pastry brushes that have bare wood handles and are clearly marked as having natural bristles. I must have 15 of different sizes and shapes. The nicest ones I have are from Germany and branded "Dr. Oetker" and, in German, marked reine borsten, meaning "pure bristle."


Realistically, any dirt/lont that the computer "inhales" tend not to collect in the intake vents but rather on one or two heat sinks (depending on Macbook Pro model) deep inside the computer. You do not want to access those if your are not very experienced with the innards of computers with tiny delicate connectors and expensive logic boards!


Leroy's sage advice is all you need, If you think dust inside is an issue, have a qualified service provider look at it.
