EVGA SR-2 and Four-way GTX 480 pretesting with Liquid Nitrogen by Deanzo - Insulation

Today I am pretesting and modifying GTX480's before heading off to Japan to assist in some 3DMark Vantage benching on a platform that will require no less than seven liquid nitrogen containers.

Insulating the graphics card, we will use three main things. Firstly, we will coat the PCB with nail polish (a conformal spray could also be used). Secondly, we use closed cell foam to insulate around the core to the liquid nitrogen container when mounted to stop air getting in and forming condensation. And lastly, Vaseline will also be applied as another barrier on the cards PCI-E slot and the motherboard.


To make the gasket that fits around the core, I first make a template out of paper so I can make multiple identical gaskets easily.


To apply the Vaseline I use a small paint brush, as can be seen in the video back on the first page.
