EEVBLOG tore one down: https://youtu.be/xQ3oJlt4GrI .
The thermal solution and packaging looks a lot like mainframe systems from the 80s (IBM, Siemens, Japanese).

That was great, thanks for linking it.
All the vintage mainframe stuff is pretty mind blowing.

There is an awesome hidden gem on YouTube: CPU Galaxy. He has a huge collection of vintage CPUs.

Dave from EEVBlog also made a video about it https://www.youtube.com/watch?v=xQ3oJlt4GrI

These old school chips were amazing. I recently watched this old mainframe chip disassmbly:

Long shot, but I believe they're referring to this: https://www.youtube.com/watch?v=xQ3oJlt4GrI
Sure:

Nearly a square foot, and the water block is built into the module.

Imagine bending one of those pins as you're putting it in.

The video was fuzzy for me but I’m pretty sure it had around five bent pins when he flipped it over to show us.

It did, but it also was clearly never being used again.

I typically enjoy Dave Jones' videos but this one was really neat. Looking at old processors is a fun rabbit-hole to go down on YouTube if that floats your boat.
