Sustainable subzero cooling setup

[DEV_9000]

I want to get a sustainable sub zero cooling rig
how do i stop water from forming up near my pc?
i am willing to put it into closed box if it means no water will get in
and is sub zero cooling inside a freezer a good idea?
(sub zero by water,and pc inside freezer to stop water build up)
(it shouldnt be since ram doesnt like being under 0 deg)
i did not find any video on youtube about this

and i have ryzen 5950x and rtx 3080
how far can i get 5950x and rtx 3080 on sub zero cooling?(@-50deg)

TIA

You basically dont. Subzero is for short term heavy overclocking. Doesnt make sense to do this nor is it cist eggectuve nor is it safe nor would any reasonable person that doesnt want a broken freezer or PC do this

like cant i get to 
5.5/5.6 ghz on cpu
rtx 3080 to 2.0 ghz or 2.1/2.2 ghz
with sub zero cooling?

shit
can i get 5.3 ghz on cpu(ryzen 5950x) and 2/2.1 ghz on gpu(rtx 3080) on water cooling

I think youll wanna make a custom loop but instead of radiators you can use water chillers, if you get a really powerful one you can go subzero, youll have to insulate your cpu socket and gpu though, and i think you might need to put some insulation around the waterblock

 

You might even want to go phase change but youll have to get 2 phase change systems for your cpu and gpu individually but thats gonna be quite a hassle and ive heard that you are gonna have to run the phase change system for a few minutes before you can even start your pc

 

Only time i tried messing with exotic cooling is just shoving a peltier on my pentium and see what happens, yea temps were worse than without the peltier, tried 4.5ghz but that just throttled immedeatly, heck i didnt even have any proper equipment so i just connected it to one of my molex to sata adapters by jamming the wires in a sata connector and shoving it on my cpu, even worse i even found water around the socket mounting mechanism, at the time i didnt even bat an eye and just go "hey ill just go remount this maybe the water will stop forming" lol i could have prob killed my board xD

Sounds like you havnt gone into depth on the subject, let me inform you on some of the ..difficulties.. that would be involved and how much work ull be putting in to do this.

 

I had a project planned a few years back for something like this, alas its been shelved. None the less here is what is involved.

 

You need either a Chill Box, or Dry Gas case* to avoid condensation.

You'll still want to put condensation protection on the hardware, like conformal coatings, neoprene, and vasaline in the CPU socket to ensure no possible moisture buildup.

Any o-rings will need to be subzero capable

Plastics cant be used in the loop, so ull need solid blocks and glass or metal tubing. Alternatively subzero capable soft tubing.

The pump will have to be able to handle higher viscosity as the coolant will likely get thicker at lower temps. E.G a glycol pump

The coolant will have to be chosen correctly for ur chosen temp target, e.g Mayhem XT1 is capable down to around -40c.

 

The refrigeration unit will need to be suitably built around a high heat load. Ideally scratch built using a Braised Plate Heat Exchange (BPHE) for optimal transfer of heat between refrigerant and loop coolant.

The refrigerant used will have to get suitably cold so to maintain efficiency even at subzero coolant temperatures. E.G R-1270 (Propene) and R-32 (Difluoromethane). R134a ,while readily available, is crap for subzero target coolant temperatures.

A large (10ltr+) res, heavily insulated would be ideal to maintain 24/7 chilled coolant. This would require 2 separate loops. 1from res to chiller, and 1 from Res to PC.

A temperature controlled circuit for the chiller and chiller side loop pump to maintain res temps.

 

* The case will require some planning, a chill box is relatively simple but still requires planning for layout, especially for the radiator, and how ur going to seal around wires

A Dry gas case requires planning for fill ports so u can reliably fill it with dry gas without pressurizing it.

 

Alot of planning involved, and a good deal of work involved to get a 24/7 subzero capable system working. Not as difficult as a 24/7 LN2 system going mind you, but still.

i have on old version of this in the garage xD

So basically you have no idea of overclocking, let alone extreme overclocking but you want to go for 24/7 stable sub zero cooling rig. Are you 12? Because you sound like a 12 year old boy who knows nothing about the stuff he's talking about.

I think that is the inherent problem with this whole post so far. Hopefully he gets that's he's in way over his head based on your reply.

 

Also I don't buy that there isn't anything on Youtube. I've seen countless video's about all sorts of sub-ambient cooling over the years, from Linus included.

I wouldnt say that ..

 

Sub ambient, sure, thats relatively easy tbh, but to be fair a scratch built sub zero liquid cooling solution with 24/7 condensation protection, just hasnt been done in a very public way.

When i was planning my project I couldnt find one, and still havnt found one to this day. Its just such a radical/odd project that its not really been done to that degree.

 

Sure people have made subzero systems before that have used converted AC's , and aquarium chillers, and even direct die phase change builds, but none really go full subzero with a liquid loop, and none sort out the condensation problem in a meaningfully long term way.

 

Those DIY projects that deal with sub ambient and subzero cooling that are on youtube are rather ....i dont want to say crap, but the videos of them are. Short, un-insightful, and overall even the systems built are very 'janky'. The kind of high quality video and project you'd want to see, like those from the likes of Roman (Der8auer), just dont 'seem' to exist with this specific project.

Maybe a strong Peltier cooler connected to an outside power source?
