Question Is it ok blowing compressed air at my laptop's fan and intakes to remove dust?

[CraigsCraig]

Hello! My laptop is HP Pavilion Notebook 15 p250nu. I have been using the laptop since like 2015-16 and never cleaned it up on the inside except a few months ago I had to swap the HDD with an SSD and then I also didn't really clean it much except blowing a bit of air at it. I don't really want to open it up at all and I watched a video (

) in which you'll see what the guy does so I was thinking is it a good idea to do that so I can get a bit lower temps cause I know it's not good the laptop to have temps of like 85 C* half the time. Thanks to everyone who helps!

Blowing dust back into the laptop doesn't get rid of the dust.

Disassemble the laptop to blow the dust OUT of it completely.

Don't do it lazy...do it right.

Well... Yea but in the video a lot of dust comes out. I'm not an expert to argue but...

That may get some dust-out, but it also may force some of the dust deeper in the laptop, which is a bad thing. You WILL have to disassemble the laptop and potentially remove the fan in order to properly dust the laptop.
Are you experiencing any overheating?

i can show you a video of a guy driving on the highway with his car in 2nd gear. it's moving down the road, but that does not mean it's a good idea.

2nd issue other than simply blowing dust back into the case is that the forced air can and will spin the fan faster than it is intended to go. this can damage the fan by breaking blades, burning out the bearings and so on.

you are much better off taking it apart and giving it a proper cleaning if you are concerned with it being dusty inside

Uh-huh.

Open the thing up and do it correctly anyway.

one use for youtube other than videos full of bad ideas, is to search for your laptop model. almost certainly to find a video taking it apart and putting it back together again. that's a video worth watching and copying

Ifixit may even have a detailed teardown of your particular device

Thank you all for the helpful answers.

Are you experiencing any overheating?

No, not really. At least Intel XTU doesn't show thermal throttling while playing Fortnite for example. I will just wait till the summer so then I have a working desktop (if you want you can give me some tips for building a desktop PC between 1000 and 1500$ including monitor) and open it up and clean it.
EDIT: I just saw your next 2 replies. I already opened this once so it should be fine. Thanks for the help once again!

And a lot of it stayed inside. Now in places it never otherwise would have been.

not the most fun but taking a laptop apart to clean it up every now and then is just good policy. i was deployed to most of the deserts on the planet and every time i spent crazy time taking apart and cleaning the sand out of the laptops we used. sucked but had to be done to keep em running right.

we used to have cleaning parties for laptops as we sat and watched the ever awesome AFN channel.

Dude... The laptop isn't overheating and I'm building the desktop after like 2 months... I just wanna be sure I will have a PC to work with even if something goes a bit wrong cause the CPU is on the side of the mobo facing the ground.

It was an aside to Math Geek.

I gave you the info you needed. After that, what you do is your own business.

I would rather use a slender attachment and household vacuum on first on the exhaust, then on the intake.

Thanks to everyone! I have decided what to do and you don't need to reply any further.
