It looks like a more efficient system would be to have a chamber in which thermal expansion is taking place right above the cpu, where it would then remain in a neutral environment, but pipe the hot vapor up to a condensation chamber. The bottom pool of that collection chamber could have a contact plate to rapid cool the liquid before it can re-enter the expansion chamber. That way, there's absolutely no condensation anywhere near the PCBs, and you can still introduce water at a temp below that of the ambient temp, so it may not be as potent of a cooling effect, but it might actually be able to be made into a smaller form factor component.

My friend who helped me build it built cooling systems for living, so it worked first try even though it was super janky. This was 20 year ago with all free junk parts with no fancy electonics. Just brute force with a lot of cooling fans and was on /off with the compressor. If I were to build another one I would just use 2 china copper block with multifins and solder thick walled pipe between. Doesn't get any cheaper than that.

Another solution to prevent condensation forming on the hardware is making a small sealed box for it and create a inert atmosphere in the chamber using nitrogen gas.

Look for something low temp. Theres also the possibility of submerging the pc in mineral oil and using a copper base plate, or refrigeration tubing coiled next to the board to super cool the mineral oil. which i believe would only crystalize at like -30 degrees Fahrenheit, so a low temp compressor would work wonders in a situation like that.

LOL @6:00 - I was one of those idiots on [H]ardforum, built a daily driver phase change setup. Opteron 165 cooled by a 1/4HP compressor, SO overkill.

I have always wondered why when overclockers are testing temps below dew point they dont just build a simple test chamber with a container/chamber of calcium chloride or even pass the air through a small evaporator to remove the water from the air. Seems extremely complicated to try and mitigate condensation than to just remove it before hand.

Not sure where my message went but it is extremely hydroscopic and it is easily available from stores and a safe to use dessicant. Damprid is an example. In a few lab setups i have done, we pass/recirculate air through pellets of CaCl2 inside of an enclosure when we have to meet extremely low amounts of water vapor. In these cases we are measuring by absolute humidity instead of relative.

May be you can prevent moisture by putting the test bench in a very small room or a case where you also put a dehumidifier. If you have no relative humidity, no condensation. :)

Use a walk-in freezer chiller running 410A, you should be able to get it to -85F with that. To stop all possibility of moisture, put the MB in a vapor tight case and use a deep vacuum pump. The blue return line [low side] should be twice the size of the red high-pressure line and there should be an expansion valve just before the refrigerant gets to the CPU cooler. Some newer split systems use variable rotary pumps and maybe you could fool the control unit to crank the compressor up or down as needed with a resistance modified thermocouple. Just some thoughts.

I love when the Linus/Alex combo shows up to really get down and flex on something really awesome. This formula is by far my favorite, and in my opinion probably the best showcase of the legitimacy of "Linus Tech Tips", out of all the sorts of things you guys do (which I see all of). Alex and Linus rolling up their sleeves together is always an instant click.

I had checked and commented on the last video. Mineral Oil you have to be careful, some have very "high" (most common is -15C) pour/freeze point. But 3M and a few others do make non-conductive immersion fluids especially for this in server/supercomputer applications, and they can go -60 to -100 C pour point. So they will stay liquid enough to circulate them at low temps.

as an hvac tech... this has to be one of my favorite videos lol

yeah vacuum like C90 told 4 months ago, or transfo oil submerged, or why not both...the board under oil in a vacuum maybe you would need at some point to adjust the AC power on the watts you are adding in the cpu ...im sure the setup is limited by the remaining safeguards

It's "silly putty." Same crap. Was a byproduct discovery from a man attempting to develop wallpaper glue. We used to take it and copy comics out of newspapers with it until we got bored of it. The formula has been slightly altered here and there over the decades, but it's essentially the same crap it always was. Art supply companies just do the same thing every other company does. They see something that someone uses as an alternative use case in their purview of products and rebrand it as if it's exclusive to them.

For instance...the entire room/environment the system is in could be could to sub-zero. That should create a super dry atmosphere and eliminate any moisture which would allow formation of condensation. I have been in cold storage units for food where the interior of an entire (very large, 20,000 s.f.) building is below zero (Fahrenheit).

For a 24/7 phase change cooling you just need a heating system to avoid the condensation in critical points... with my Vapochill I've used this system for several years without any condensation issues. I also suggest to put the phase change system in a different room... you just need a hole in the wall in front of your case ;-)

Have you never thought about skipping all the insulation-goo, and instead just build the board into a close-to-airtight box and flush it with dry air / nitrogen? Takes a bit of development at first, but it will make your live much easier the next hundred times you fool around with sub-zero cooling.

I once worked at an R&D dep where among other things we did a lot of thermal testing. What I learned there was that you really want to put the thermocouple inside the cooler block. The exact location depends on what is that you want to measure/model but typically I think it we drilled a tiny hole right above the chip, stuffed the wire in it and filled the hole.

I got phase change unit in storage. Time to dust it and put back into use, it's able to do -60 degrees of C on evaporator head all day long.

I'd actually say it's kind of impressive how well a two gen old CPU is holding up all things considered.

All you need is a sub ambient case with a seal that you can control the internal humidity of. I chose a 2 glass door refrigerator. This allows me to run a sub ambient coolant and have virtually 0 moisture issues Several pc's in the fridge all running of a manifold geothermal cooled water loop. gives me a steady 10 Celsius coolant temp. Now next project is the refrigerant cooled setup, going with full cover front and back mobo water plates which will circulate the geothermic chilled coolant. Then one of these phase blocks but I am considering a larger block that will serve as both the cpu cooler as well as the gpu cooler. like a big L shaped block. Don't have the machining tools here so will be using 3d printed patterns to cast copper parts from. Pretty sure I can cast a complex internal structure for the evap block no solder required.

I actually ran a vapochill on my gaming rig for a couple of years, was insane when it worked but a nightmare when something needed reseating or upgrading. My Athlon 64 3700+ San Diego and later a core 2 duo 6600 really liked the cold when oced.

You wouldn't want to use oil for that. You'd want to use anhydrous alcohol. I'd also recommend a sealed enclosure with an air gap that has been purged with a non-condensing gas like nitrogen. I doubt they'd be able to run it cold enough to condense nitrogen with that system. Additionally, I'd personally be quite concerned about trying to use a fluid that is combustible and has a particularly low vapor pressure.

What if you cool 3M Novec with this thing using a heat exchanger and immerse the entire PC in the Novec? Gets rid of all the moisture issues and can handle sub zero just fine.
