I get roughly equivalent temps on my 5950x but I am using an Ice Giant ProSiphon Elite (it’s an air cooler). I typically idle around 32c-38c under light loads, and when i’m really pushing the processor it will top around 70 and then settles into the 60’s. I use Arctic Silver MX-5 and it has had plenty of time to settle in, been in the system over a year now. In the summer I don’t have AC in my house, and even on very hot days (over 100f ambient temp in the shade), the cpu temps never go above 75c. Thermo Siphon tech is pretty great, it is more commonly seen in industrial applications where there are truly crazy amounts of heat being generated. Up until recently PC’s haven’t been hot enough to even be able to use it.
Wendel did a video about it.
Linus did too
The Ice Giant is a pretty insane air cooler though, most cases it might not even fit inside.
I’ve got pictures of my build here.
I do not suggest putting the Ice Giant on anything less than a 5950x though, the heat sink is designed to cool big processors, and if you don’t have enough hot die-space and lots of cores to cool, it will not perform well on normal consumer grade CPU’s because their die’s are so tiny.
