LN2 insulation Guide

[sacha35]

First of all we need to make a platform so that the motherboard can be mounted safely and is stable, this is one that i quickly knocked up, as you can see it has feet so that the table will be nice and flat and wont move around, also it has some standoffs so that the motherboard can be fixed to the table.

Next up we have to make sure that the rear LN2 mounting bracket has the mounting fixing attached to this plate.

Then once this has been done we fit some insulation to the rear mounting bracket.

Now that we have this out of the way its time to start sorting out the motherboard, i do this by painting around the CPU area with some nail varnish or none conductive Electrical lacquer, then i spray the whole of the rear of the motherboard with some electrical lacquer so that this is then fully insulated from any damp that may be present when using LN2.

Once the all this has been done to the motherboard leave overnight to dry and then we need to cut some neoprene out to fit around the CPU area, i like to use 6mm thick neoprene built up in layers.

As you can see i also use some thermal compound around this area of the CPU once the neoprene has been cut and fitted to the motherboard to give just that bit more of a thermal barrier.

I then add another layer of neoprene on-top of of the CPU which has had a hole cut out the same size as the base of the LN2 pot.

Then again another layer of neoprene so in total we have three layers of neoprene, again this hole needs to be just that bit bigger as the LN2 pot is tapered, and again a small amount of none conductive thermal compound on top of the last layer of neoprene so that it will make a nice seal once the LN2 pot is fitted.

Now that we have done all the motherboard insulation we can move onto fitting the LN2 pot, first of attach the hold down late to the LN2 pot.

Then we add a thermal probe to the LN2 pot at the side near the base of the pot and then fit the neoprene base gasket to the bottom of the LN2 pot.

Now we need to put some ceramique thermal compound onto the base of the LN2 pot and CPU, i use a small amount on both and smooth over with a small piece of plastic as i can get it.

Now its time to fit the LN2 pot to the motherboard, i use some springs here as this gives a more even fitting when tighten down, once this has been tightened down we put on the top neoprene N2 pot insulation gasket and then fix the motherboard to the platform we made at the beginning.

Cracking guide there sacha mate.

You can use DC Dilectic grease instead of thermal grease right?

Yes mate Dilectic grease is fine to use, the only reason i like to use thermal grease as it is easy to remove

V good mate, ill get some pics up off mine also so it gives some examples and ideas. :D

Time is the key and not to rush. I think around 1-2hrs on neroprene and sealing for me to get it sweet. :D

[Aqua-Pc's]

great guide and those stands are quite sweet too!

This just makes me want this even more!!! Great guide there, and a lovely looking mobo tray too.
