Nitrogen and liquid coolin

Befread · January 7, 2019

I was watching the Chilling Threadripper 2 video and I was wondering could you defeat the condensation problem if you sealed a case ran the liquid cooling in with the same system in the video and then flooded the case with nitrogen to displace the air? You'd need to liquid cool everything including the motherboard, but would it be possible?.

Possible? Yes. Practical? No way in hell. You'd need to be pumping in a large amount of nitrogen to counter the leakage and I'm sure other problems would arise.

A slightly less radical option would be to submerge the system in mineral oil while running tubing externally.

Why would anyone bother with nitrogen when you can just dry the the air?

Thanks, I was looking for something like this before I posted but I couldn't find it.

Yes , and infact its easier than one would think.

During my years of research into a project build i have on the backburner atm, i went from a partialy sealed case and methods for dryng the air ..to eventualy realising that building an airtight case designed for normal air pressure can be easily filled with nitrogen for a dry air enviornment.

Nitrogren is slightly lighter than air, so all u need to do is build a airtight case (very small leaks are fine as u wont be running it presurised) and use 2 hose connections. 1 up near the top, and one near the bottom. Simply open up both and feed Nitrogren in from the top untill its starts coming out the bottom. Seal and let it sit. Then do it again. repeat this a few times and ull be left with a case full of primary nitrogen, remember that air is primarily nitrogen anyway, all ur doing is displacing as much of the other gasses and moisture as possible.

The motherboard VRM's would idealy be cooled with blocks, but the RAM and such is fine to leave as is.

You can use a humidity sensor to keep an eye on things, without fans and pressure, the inside of the case should remain a dry air environment, even if it has small leaks.
