The art of high performance computing

First, thanks for sharing these details, I find them fascinating because they are not so common to be read or heard about.

> Delta T between two sockets is 5 degrees C

And secondly, ~5-10 degrees is what I see on my dual-socket workstation, and have been wondering about this delta ever since the first day I started monitoring the temperatures. At first, I thought that the heat sink wasn't installed properly but after reinstalling it the delta remained. Since I didn't notice any CPU throttling or whatsoever I figured it's "normal" and ignored it.

Hey, no worries. Using one is equally fascinating as much as reading about it. It feels like a space shuttle, so different, yet so enjoyable.

I mean, water travels from one socket to another, so one processor adds heat equal to 5 degrees C under nominal load. The second socket doesn’t complain much, but this is enormous amounts of heat transferred in a such quick pace.
