Koolance CPU-LN2 Rev2 Kit
Just like the first revision of the Koolance CPU-LN2, Koolance has gone with a mid-height mount and those pesky two-piece mounting rods. I love the chunky acetal mounting bracket and the gigantic thumb screws but I cannot stand the mid-height mount placement and those mounting rods. The mid-height mount poses all sorts of issues if you aren't careful with insulation as you can see below. Those two-piece rods are just clunky, just give us some plain Jane threaded rods. If it isn't broken don't fix it.
Notice anything not good? Condensation is bad, you want to reduce it as much as possible as it has this tendency to thaw out and drip. The ice in the picture above was only after ~30 minutes at -90 Celsius. Luckily I was testing wPrime 1024M at the time so I had a lot of LN2 going through the pot. However, when I was testing Super Pi 32M I was hardly splashing LN2 and the condensation began to thaw and drip down the pot. Keep this in mind, you can wrap some paper towels or go Team Japan on it and just stuff toilet paper all over the place.
Koolance thoughtfully included a bore hole in the CPU-LN2 Rev2 base for inserting your temperature probe. For dry ice you may not need a temperature probe but it is necessary for liquid nitrogen testing. Just fill the hole with some thermal grease and stuff your probe into it. I secured the probe to the pot with some painter's tape, this keeps you from pulling the probe out on accident.
I feel like the CPU-LN2 Rev2 looks like some sinister weapon. I'm just waiting for the noise of the Death Star firing sequence to emanate from the CPU-LN2 and have it blast a hole through my roof.
For transportation Koolance has a thin plastic sheet covering the base of the Koolance CPU-LN2 Rev2. Just be sure to remove it before mounting up the pot.
Talk about a mirror polish. Who knew your LN2 pot could double as a mirror. Sadly this will get scuffed up with use. I've got fine etchings in the base after mounting it a few times to my Xeon w3570 and the IHS grinding into the pot base.
