Mineral Oil at low Temperatures.
Today, pondering about cooling solutions and a little daydream of over-clocking, I thought about what happens to mineral oil at low temperatures. Temperatures the same as liquid nitrogen. I had an idea to have a column of liquid nitrogen sitting on the CPU, nothing new. But then to drive out moisture and dissipate heat better, immersing the rest of the mother board in mineral oil. The only problem is is that I am unsure of what happen to the oil at such low temperatures; I would believe that is get thick or forms a jelly. Thus two questions are posed here:
1. What happens to mineral oil at low temperatures?
2. Has this been done before?
