If nothing more, its a nice vid.

they should have done it with pure water because it is far better conducter than oil, but still the treating of components is longm read this a while back, very interesting. although a modified water cooling system which is reasonable would have been better

i think the point is the oil was non conductive

i meant de-ionised water after all electronics have been treated with something anyway

If you read the above link to Tom's Hardware build, you will see that they did start off with distilled (de-ionised) water but it failed after 5 mins due to short circuit.

UV reacting non conductive coolant would be ace to use. Better than oil for cooling and I would imagine is just as non conductive. PrimoChill and Feser did some tests on a running pc.

you cant totaly de-ionise water..... it naturaly converts into H3O+ and OH- ions whatever you do, and even tiny un-controled currents can screw up computer circuits.

i have a good knowledge of chemistry, since the first post i said to cover all parts with some sort of waterproof layer, ie some sort of varnish, then it wouldnt matter..

 

[simonnance]

Surely such a waterproof layer will inhibit thermal conduction, and/or will melt with high contact temps on chips?

Chemistry is one thing, but you can't beat the physics.

De-ionised water is not used for a reason. You would have to cover the entire board in insulting crud which would negate the point of submersion cooling in the first place.

Tom's hardware only sealed the socket/cpu with silicone. The rest of the motherboard and components were unsealed, apart from the gfx output which was extended outside with a dongle and then sealed with silicone.

Drives were outside the case though iirc.

what exactly do you think will happen to the oil after some time? not much better than using water

It's certainly not going to ionize the same way as water. If you knew your chemistry you'd know that
