- There are few things that separate nerds from normals…more than liquid cooling.…By liquid cooling, I mean you take your CPU,…and you put some big metal mount on it.…This mount has got a hole in and a hole out.…There's a bunch of holes in the middle,…and liquid goes through this big mount,…taking the heat away, and then it's run out…and then cooled off somehow and cycled back.…Liquid cooling's been around for a long, long time.…Over 15 years now,…and back in the old days, it was pretty ugly.…There wasn't anything very standardized,…and there was a lot of custom work that had to be done.…
