Could you cool a CPU with electronics Duster?

I was just wondering if you could cool a CPU with electronics Duster. Just wondering.

You mean blow right on the chip with a duster?

 

Hell to the no

Definitely not haha, maybe if you blew through a tower cooler heatsink but that would not be sustained. Also electronics dusters are not meant to run for extended periods of time.

You can't cool a CPU that way simply because it outputs too much heat. This does remind me of the one time I tried it out though, it was with an Nvidia 7300 LE, a very old card that had a tiny heatsink and no fan. When I played games on it, the card reached 80 degrees Celsius and it idled at about 60C; turns out the thermal paste had dried out completely and there was a pretty sizeable air gap between the GPU and the heatsink, so blowing compressed air onto it was able to lower the temps to around 50C. Definitely wouldn't try it again with a more modern card though.

not even this.

Reminded me of a time I was working in Croatia. It was over the summer about 18 years ago. Heatwave everyday in the 30s and the fan packed up on my lappy. I ended up only being able to use it with room fan blowing right through the vent. But that was blowing over a heatsink not directly onto the CPU. 

 

After coming home I did manage to get a bit longer out of it by using a cheap USB fan.

That's not a good idea. Your typical can of compressed air will actually create frost on the target. A shopvac/dustbuster doesn't have enough surface area to cool with, that's why the heatsinks are 100x massive than the CPU. All those cooling fins are so that heat is removed faster.

 

Like, if someone's goal is to create a quiet cooling system, they would quite literately need to immerse the entire system in a stable non-conductive liquid (which can actually be done) as long as you replace any fans with large heat sinks, and don't dunk the power supply in it. Also kiss any warranties and upgradability goodbye, since you'll never be able to clean the oil off to replace anything.

 

The site I linked actually says their mineral oil solution doesn't affect fans, but the fans don't really do anything. I almost want to see someone give a full RGB system a mineral oil bath and see if the LED's and Fans last.

 

Looks like they also stopped selling the kits because of patents that came out in 2007. So that's probably why nobody has gone back down this path for gaming PC's.

Technically anything can cool a CPU.

Most things would do a bad job of doing it though, electronic dusters included.

I heard mention here once was that the problem was they couldn’t get all the sulfur out if mineral oil and it eventually messed up plastics.  LTT did a mineral oil computer revisit video and the did some talking about how crispy the old cables were.

 

As for fanless PCs it has been done.  There’s a company called nofan that makes passive CPU coolers.  There’s a whole website called SilentPC that used to do stuff about it.  I understand they started making their own hardware though so their reporting became suspect.  That may have been the site where the guy built his own a echo of chamber for testing out of blue fill insulation.

 

 NoFan coolers are gigantic though and the biggest one that’s larger than a noctua d15 still has a claimed tdp of only 95w. I personally would be Leary of putting a 65w chip on one.  I would love to see how a 3600 does with a nofan 95.  Volunteers encouraged.  Money will not be refunded for damaged parts.

 

Ive also seen cases that were themselves gigantic heatsinks.  They’d be carefully designed to maximize chimney effect in the fin channels and could therefore be set up in only one direction.

 

A gaming CPU and GPU together though are going to need something around or north of 300w of cooling though and I think it’s just plain outside the performance envelope of passive.

to all the commenters here, yes. Yes you can:

 

 

However, this is not without it's caveats like this won't actually work very long. You can do this just long enough to get your computer to POST, and not much else. You also have to hold the can upside-down so the frozen liquid comes out and cools the CPU.

 

Using computer duster to cool the CPU constantly however? Probably wouldn't work.

This is so unorthodox, lmao. Or how the kids today say it...

Practically Victorian ghetto.  That mobo is older than mine.
