@mattspeller said in ZTE Shows Off Immersion Server Liquid Cooling at MWC: I would really need to see this myself to believe it. Even with mineral oil you need some kind of heat spreader. I can see this working no problem with a modest hunk of copper on the CPU but bare? Yikes. sceptical.jpg They show them working with no spreaders on the video. Mineral oil doesn't cool anything like a two phase. It's not "even with mineral oil", because it's among the bad options. It moves heat well, but moves physically very slowly. The two phase moves heat SO quickly.
