its liquid electrical tape you buy from homedept? Its like a conformal coat. Yea electrical tape or any other type of tape is a joke, you have to use some sort of conformal coat. LET(liquid electrical tape) doesn't even crack under the cold of LN2 if done right. You paint on layer too thick to see through, and then it will easily come off.
When I had my chilly1 unit, they provided one very thick, circular pipe insulation of neoproene, and then it would be compressed and it would become airtight under the seal. People are dumb off their bats when it comes to insulation, some of the things i see recommend by manufacturers to insulate seem like they have never been tried.
This is how real overclocking was done, voltage mods, and everything basic, and it was fun. Now everything is not so fun. Anyways i sold that unit for $300 bucks, i bought it for $400 including overnight shipping from las vegas from chilly1, this was before he ripped everyone off.
