Preparation for Subzero Benching
Since electronics are rather partial to getting wet you have to do your part and keep them dry. Since my last review I've moved over from plasticine and started using rubberized artist eraser. Normally used for erasing pencil and shading, artist eraser is also very pliable and is very useful in sealing up your motherboard socket. Keep in mind that the eraser isn't a stellar insulator, it simply forms an airtight seal. I actually haven't removed that eraser from my Classified in months and after going through several hundred liters of LN2 I'd say it is sealed up nicely.
Typically I don't even remove the thermal grease between sessions but since this is a review and all I decided to start fresh. Nothing fancy here, just apply a dab of Arctic Silver Ceramique to the center of the IHS. I then mount the pot and run the system at stock clocks till the IHS is around 60 Celsius. Warming up the Ceramique makes it less viscous and helps thin it out to form a nice bond to the IHS and pot base. Take note of the temperature probe pressed up against the IHS edge in the blob of Ceramique, that is how I was measuring IHS temps.
The above set of images shows you how the liquid nitrogen disperses itself through the CPU-Ln2 Rev2 base. Due to all of the surface area the pot is highly reactive and eats nitrogen with a voracious appetite. Going from 30 Celsius to -80 Celsius took a little over 70 seconds if memory serves correctly.
I find dry ice benching to be a miserable experience so I have only tested the pot once with it. Here I have about 1/2 cup of acetone in the pot along with several small chunks of dry ice. Acetone is necessary to transfer the heat from the pot to the dry ice, otherwise you would have poor thermal conductivity and terrible performance. For those of you curious the CPU-LN2 Rev2 has roughly 2.25 cups of internal volume.
