So has anyone actually tried oil cooling?

Saw a few demos on YouTube and thought it looked awesome...just a bit messy :P

Do you mean a tank full? You will get better temps with water done the conventional way. But from what ive seen oil can keep stable temps over a longer period

You can cool oil in hydraulic systems in one of two ways in general. Either a water cooled heat exchanger or a forced air draft oil cooler.

I used to use Oxford Controls air blast oil coolers in our machine tool spindle hydraulic power packs, like in this photo: http://www.box.net/shared/1huipv0jg2

I have a feeling this is not what you mean.....:banana:punk

im talking about filling an air tight case with oil, covering all components except the psu ;)

That's what I figured you meant. Why not the psu as well?

Oil will damage the inside of the PSU I assume? Don't really know tbh

Given its non conductive I wouldnt think it would matter what you put in it. Hard drives may not like it though, or anything with movin parts

It really is an idiotic idea that shouldn't be given the light of day even in idle passing fancy.............:thumbs:

Well sorry bout it, it may cause difficulty when the oil gets dirty, but it actually keeps the system at quite a reasonable temperature.

All i know is that when seeing it done, they didnt cover the psu and i assumed there was a reason, the HDD was fine, system ran perfectly.

Use an SSD if your worried about the hard drive

Why not just put the whole computer in a freezer, bring wires out to the components used in the interface, silent and cool at the same time lol.

But what happens when you need to do maintenance and replace something

That would make more sense than the filling with oil nonsense :)
The principal reason I called it idiotic is that such a system actually runs hotter, as witness the huge radiator they eventually used in huyeybots reference.

Though a caseful of oil has a large heat capacity, ie mass times specific heat, the heat from the GPU and CPU can only be removed by natural convective heat transfer from the sides of the case. This would be pretty pathetically small unless the whole case and hence the oil heats up appreciably.

If a pretty-pretty aquarium look is required, then it would be better to have water or oil filled "double glazed" case sides.

The amount of troubled gone to, to produce an oil filled case that runs hotter than conventional, is just ludicrous.

Haha this made me laugh:


Overall, the biggest downside we have found is that the oil wicks down the cabling and makes a mess. Its amusing at first to find oil seeping out of your mouse, but gets annoying very quickly!

Wouldn't there be a moisture risk with this method?

Yes bob_doe_nz, the computer should be sealed in a large plastic bag before it is put in the freezer to avoid the moisture/conduction problem, probably a desiccant would help as well.
