PC cooling methods efficiency measurement, need info

post #1 of 4
Thread Starter 
I have a college project about computer cooling, and it requires mandatory Excel chart with geeky numbers and such. I can't find much info about comparing these head on, I think the best way would be list how much watts they will dissipate, but vendors rarely put that info. Can someone elaborate on these please?

Ok, I will use the most effective stuff out there for each method.
Air cooling - Noctua NH-D14 [Max dissipation ?]
Water cooling (mainstream CPU closed loop) - Eisberg 240L [Max dissipation ?]
Water cooling (high-end complete solution, CPU+GPU) - Aquaduct 720 XT Mark V [Max dissipation 1400W]
Peltier [Max dissipation ?] - lost on that one, my guess is more effective than water
Phase change - LD Cooling PC-V2 [Max dissipation 300W?] It does say 300W on the specs, but it will look that phaser is way less effective than w/c. I think it can theoretically do much more, maybe 3000W?
Oil submersion [Max dissipation ?] - dunno much about this one, very custom stuff, hard to calculate dissipation, maybe 2000W? Hardcore Computer used to sell custom PC's with 4-way SLI and top CPU.
Liquid nitrogen, dry ice - this one is not for normal use, and it probably will be over 9000W, heh, no point in including that in the graph.

Just my view on this but the question is very much "how long is a piece of string"?

I can see how some cooling solutions have a maximum heat dissipation, things like peltiers, phase change units and heat pipe cooling solutions as their design only allows for a certain amount of heat transfer......but bigger more powerful designs or use of multiple devices will transfer more heat.

But with other things like water radiators the heat dissipation will depend on the temp delta between the water and the air and the air flow through it....there is no max heat dissipation value in my view....but of course only a certain temp delta is possible due to factors such as the water boiling or going beyond the temp limits of the system being cooled.

So I think it's only possible to really to give a more general order being

air cooling < liquid cooling (water cooling, oil submersion) < peltier cooling < phase change cooling < liquid gas cooling (liquid nitrogen etc).

Thanks. I know the possibilities and variables are endless, but my idea is to simplify it to sort of car-level logic that anyone can understand, like there's 4-cylinder 180hp (air), V6 300hp (water), V8 and so on. Scientifically precise numbers are not required, just an estimation will do.

in that case, you can just pluck numbers out of thin air which support the point you want to make....

However, if this is a dissertation and you need to include sources... you'll have to do some work... you could send an email to the manufacturers of the more popular HS/towers like Noctua/Prolimatech/CM/evo.... and ask them for numbers/charts

And charts covering the dissipation range it is... as a simple 120.1 UT60 mm rad can dissipate +500 Watts providing the water/air delta temps and airflow is large enough... its just not practical or possible in our simple systems.

This is not a simple project you can bolt together on a Friday afternoon.... at least not if you want to have some degree of credibility.
