Liquid Nitrogen Cooled Fluorinert(an overclockers dream)

Isn't that great? I must confess, I was anxiously reading each part as they appeared. What's funny to me is the extremes they had to go to get liquid N2, when I use 100s of liters of the stuff each week.

Well, John, why don't you smuggle some of it out and sell it here.. Canisters of liquid nitrogen for sale in MURC's happy shopper!

What a complete waste of money! Geesh this guy should have noticed the phase change that Flournert has at -101c... then you cool it with a LN2 at -196c? Good grief

The parts would freeze and be damaged.

To immerse the parts in liquid Nitrogen, all you have to do is support them above the surface of the liquid in the cold vapor above the liquid in a covered and fairly well sealed container (not totally sealed). Once they have cooled down slowly (over a period of an hour or so) you can immerse them by pouring the liquid gas into the container until they are submerged. As long as you don't immediately pour the liquid gas onto the mb, this will work. Not a big deal.

I kept expecting to read that one of them kicked a hole in the motherboard container in a drunken stupor; Sure would have been painful watching $1000 worth of Fluorinert leaking unto the ground. Gotta admit ... it was captivating reading though.

The FC-40 they used has a pour point of -57C, the FC-87 is good to -101C, but was probably twice the price. Either one was doomed to failure with LN2. Neat stuff, but for $1k, I can buy a hellova processor that doesn't need anything but a good HS/Fan.

I just like that they were willing to spend $1000 on coolant to run their rig. As it was evolving, I thought it was a joke, but they actually did it. A dry-ice/acetone slush will get them to -80 C, as I believe they and others here have pointed out, but the fun has been done. The is taking "computer hobbyist" to the max!

I like the idea of cannisters of liq N2 (hey, I even use liq. helium occassionally) at the happy shopper for your own cyrogenic experiments....

I wonder why he just didn't immerse the components in liguid nitrogen itself? I think he should have gone all the way and used liquid helium. Now that would be cold!!
