Below ambient CPU cooling

[BadgerXL]

I've seen linus sub ambient/below zero cooling, having trouble with moisture, is is possible to vacuum seal the socket, then cool, i dunno if it would work because the back of the socket may still be too cool, but it SHOULD help with the cpu side at least, no air = no ambient moisture to condense

 

I think it may be a good video idea, i'm not gonna do it, i'm not nuts

The idea of creating a dry gas chamber/case is not new and has been suggested in the LTT video suggestions thread before a good while ago. I doubt they will do a video on it, its to much of a niche use case and not something any1 should do unless they are a big enthusiast looking for some fun and heavy overclocking.

 

I myself had finished designing a scratch built subzero chiller, dry gas case, and coolant loop a few years ago, but life intervened before i could start building it and its on hold currently.

its certainly doable, and has potentially to be a great 24/7 subzero system, but its a lot of work.

clearly you haven't been watching ltt videos long

 

thanks though, i didn't know if it was even feasible, but thought it would be a cool and/or interesting for a video, just popped into my head after i watched the sub zero cooling thing again today

~SNIP~

Maybe i should have been more descriptive.

 

The amount of work they would need to do, to build a system like that, for the size of the video they would get out of it, would likely not be worth it.

 

They'd have to build a 'good' subzero chiller, not just the ghetto modded AC like they used last time. Scratch building a chiller isnt exactly easy, and they'd be dealing with potentially flammable refrigerants like r1270 if they wanted something easy to get, cheap and with a low boiling point, rather than r134a which is also easy to get but isnt really cold enough.

They'd have to build a airtight well designed PC case

They'd have to successfully replace the air inside with a gas like Nitrogen, Helium, or Argon etc.

They'd have to find and test a suitable coolant, like Mayhems XT-1, something capable of going more than just a few degrees below subzero.

They'd have to test/replace all their o-rings in the PC side loop with subzero capable ones, or build a braised copper loop with braised waterblocks.

 

I've been through all these, and more, design aspects myself, and while its easy for me to look back at all this now, it still took many revisions of designs to get to this point which they would also have to go through themselves, then they have to actually build it.

 

I would love to see them do it, if not for anything else than to allow me to see how they go about it before i eventfully do. But i cant see if happening, LTT isnt exactly known for doing things 'properly'

 

I mean the closest i would expect them to go is finding a old chest freezer, putting a liquid cooled test bench inside, drill a hole in the side of the chest and pump in some gas while using their ghetto AC chiller.

Proof of concept at most but not exactly a 'proper' build.

to be honest the most i was thinking of was 0 degrees, going full liquid nitrogen/helium is it's own crazy bus, the idea was more of removing the air around the cpu block so it wouldn't condense the moisture, i would say a vacuum chamber would be fine, but then the VRM's and other components would be dead, i don't have the imagination nor technical skill to do something like this, but i've seen some crazy stuff on this channel, sure alex could 3D print some sort of spinning inside out RGB thing to do it lol

 

And if you do try it yourself, i wish you the best of luck

As it been stated above you will need to liquid cool everything cpu, gpu, ram, vrm, chipset. It also has to use an airtight container as a case with some gas such as nitrogen or air with 0% humidity. To avoid the condensation. Antifreeze is a good coolant as it can go as low as -35-40c but it brings another variable into equasion. All gaskets, seals and tubes must be antifreeze resistant (or oil/fuel) resistant. I would of gone for all metal blocks. And that will cost you an arm and a leg unless you are going for world no ln2 oc record it is absolutely pointless.
