I don't want to use compressed air to clean dust from my G751JT. I'm a bit OCD about the health risks. Is it safe to use canless air on it? I heard vacuums are a no no because can damage the components. Concerned that canless air might do the same.

Or, alternatively, do I need to clean the vents at all?? I faintly remember someone saying somewhere that dust filters at the bottom of the G751 prevented dust build up inside the laptop.

Thx for ur advices --

I'm confused what is canless air? Do you mean duster / canned air? https://en.wikipedia.org/wiki/Gas_duster <-- that stuff?

What health risk are there with compressed air? The stuff is duster is toxic... it would be far worse for you than using compressed air even though duster isn't exactly dangerous.

Anyhow if you don't want to blow gas on the vents to clean it you can always break down the laptop and clean the fans out with a bit of alcohol and cloth / q-tips.

Really I wouldn't worry about cleaning it unless you start to notice your thermals getting bad, or once a year or so unless you smoke around your laptop.

Apologies. By canless air I meant a couple dust blower devices that were selling on Amazon as alternatives to canned air.

Anyway. You think I should wait a year before cleaning? Waiting this long won't harm my components?

Also by compressed air I meant the usual canned air. I wrote this on my smartphone :s

These look good but expensive in comparison to a can of air

Unless your sensitised to ghg's would using it outdoors not be ok?

Unless you keep your G751 in a really dusty place, have lots of pets or smoke, there's no use in panicking about its internals getting dusty UNLESS you are keeping an eye on your GPU/CPU temperatures and have noticed them getting steadily higher.

I'm not really convinced that blowing air into the vents, canned or otherwise, would make any difference to be honest. The only way to properly clean the fan blades is to open your laptop up and very carefully clean them with cotton buds and alcohol - but this should be a once-a-year sort of job. There's a good guide here (https://www.youtube.com/watch?v=3x7px8mx5LU) on how to open up your G751, but you really should just need to slide the keyboard down so that you can get into the fans instead of properly dismantling it, which shouldn't affect your warranty.

I'd be far too uncomfortable using canned air/gas dusters because I'm OCD about the health risks they pose. Even outside. Really. (I'm probably overreacting but trust me it'd bother me).

The money is no problem. Are such devices safe to use on the G751? Don't fry the components like vacs?

I might just take Clockwork Satan's advice and wait a year. Especially since his rig is identical to mine.

I'll just echo clockwork's advice... it doesn't really do much good to blow dust around the inside of you machine. Typically when dust builds up to the point where it is hindering cooling it creates a mat of dust on the far side (from the outside of the system) of the heat sync. I've had no little luck in cleaning such dust buildups from the outside.

If you do manage to dislodge the mat of dust.. then there is a chunk of dust floating around your system that could just end right back where it started or worse messing with your fans.

Ive been using this for dusting since they sent me a demo unit 2 years ago and it works well enough but it doesnt have the same pressure as canned air.

well without that gadget i would go through 8+ cans a month at $4 each for all the systems i work on so even though i didnt pay anything for it i would have paid $100. If all you do is clean your laptop twice a year then no it doesnt make sense for you but the poster asked specifically about other options because of health concerns so for him/her it might make sense.
