What about compressed air cooling?

 

[SPS]

It would be A. Very noisy or B. Expensive

 

[jamesriley94]

and C - not perform very well?

How would you intend to actually apply the compressed air to cool?

I think he's just going through a phase right now were he wants to do something stupid/ridiculous like put 15 fans in a case of cool a CPU via compressed air.

 

[jamesriley94]

hahaha - I have a mate that wanted to run copper piping all around his case with holes in, and attached to an air compressor to blow dust off the motherboard...

 

[ruairi.C]

lllllllmmmmmmmmmmmmmmmffffffffffffffaaaaaaaaaaaaaaaaaooooooooooooooo

 

[yassarikhan786]

Not a good idea at all

 

[Innocent159]

I'm just here to find out if it will work.

 

[Perturabo]

How are you intending to do it? Compressed air tends to come from a very small nozzle in order to achieve a high pressure jet. So you will more than likely have a thin jet blasting at one specific place and not achieving much. If you had multiple jets then you will just create turbulence and impede air flow in any particular direction. Plus compressors are noisey and compressed air can quite easily damage components.

So its not worth it to try?

 

[Perturabo]

Like I said, how are you intending to approach it? It sounds like a bad idea from what I have in my head but mabey you have an interesting idea in mind?

 

[jamesriley94]

Not really - but how would you even use compressed air to cool a chip?

 

[Innocent159]

Like water cooling, tube connected to the compressure and onto the chip. the idea is that you get air in better than an intake fan because its forced in

 

[Josh Weston]

Also, a test was done on the massively high RPM fans, like 10,000 rpm, or something similar, and the CPU temperatures didn't decrease that much on a Noctua-style tower cooler. Compressors are loud, and you'd be so much better off with a water loop.

 

[jamesriley94]

I don't think air would conduct the heat well enough to be able to cool it sufficiently.

As for the pressure vs fans and stuff - if you opened up the small tube end to 120mm fan size, it would have next to no pressure. The pressure is only so great because of how small it is

 

[Perturabo]

Air has a conductivity ~24 times lower than water and a specific heat capactiy about 4 times lower. So setting up a closed loop cooling system with compressed air rather than water would be awful.

A rough estimate of the pressure you would need for the compressed air to cool as well as water is 861 atmospheres. To give you an idea of how large that is, the maximum rated pressure a nuclear sub can take is about a tenth of that.

 

[FOX91]

The thermal conductivity of air is much much lower than that of water. That says it all.

Edit: Perturabo was quicker.

 

[Innocent159]

So a heatsink with a water cooler attach(if possible) would be better?

a what?

A heatsink like thermalright HR-02
