If you mix propylene glycol into the water you can run below 0 c. Also, I'm pretty sure somewhere in the manual it will say not to run below something like 14 c without adding antifreeze. If you were able to look into the reservoir you would see the evaporator coil is likely coated in ice at the conditions you're running.

They should definitely add inhibited glycol inside the cooling loop (>25%). Ethylene glycol should be fine too and has better thermals

Chiller development team member here. The compressor is not cycled in a laser application, they vary the cooling capacity by use of an electric expansion valve. It can be seen behind the compressor by the evaporator (which is not in the tank, it's attached to the back panel) Btw, SMC (a competitor to Thermo Scientific) offers rack mount chillers up to 5kW and with the 0.1 degree tolerance.

That cooler we use for industrial applications haha! Linus, the Low T warning you can set in settings. Some lasers have a min temp around 5C for condensation issues. Also some of these coolers have a Modular speed pump. If not use a bypass (T connectors between the Inflow and Outflow with a valve so adjust flowrate and bypass the main circuit) on the circuit to lower the flow to the CPU so the water gets more time to take the heat away from the block. You can set your cooler really cold.. but if the water doesn't have time to collect the heat it is worthless.

I've used similar Thermo chillers at work, it's cool to see inside one. The small coolant reservoir means it reaches operating temperature quickly when turned on.

[@Murasenki]

CAREFUL running just water in that cooler. If you set the coolant at 5ºc (I don't know what Freon is inside) the gas will be evaporating at -2ºc. You will destroy your evaporator with ice. P.S. the evaporator in the black box with 4 tubes in the bottom right of the machine, the plastic container is just a reservoir. I hope to help, thanks a lot for your content guys!

[@timothyfischer5160]

Sure, but even a traditional ac with a fairly "weak" refrigerant will freeze up if no house air is blowing over the evaporator, but with some heat from the computer traveling through the other side of the exchanger I would imagine you won't freeze up at that temp. This thing does have a bit much on the side of capacity though, so you may be right.

The black "box"with 4 tubes isn't a evaporator, it's a heat exchanger between the liquid in the chiller and the liquid in the attached system. That's why the tank is so small. it holds just enough to compensate for expansion inside the system.

What if you de-lidded the 13900 and then made a custom lid with a water block built in? I bet you could get a much lower temperature with the heatsink being the water block

[@cgi2002]

Honestly at this point thats the bottleneck, doesn't matter how cold the get the collant if they simply can't transfer the heat fast enough off the cpu directly. They've reached the capacity the materials themselves ability to transfer heat. They may actually with their fancy new metal 3d printer be able to come up with something that could work, but I suspect it can't print in materials that would be better mediums for heat transfer. I did many years ago see a fully submerged pc setup, but I don't know if you could build such a thing for this, and even then I don't know if you'd still need to de-lid the cpu and if even doing so would damage it or if it could survive the submersion in that state.

[@Naturalhighz]

@@cgi2002 you realize the comment literally talks about getting better heat transfer by doing direct die cooling. what they tried in the video was with the factory heatspreader on the cpu. if they do direct die with liquid metal they should get significantly better heat transfer

[@cgi2002]

@@Naturalhighz yes I know and I agreed, my thoughts was they'd need to make a custom fitting for that, but that comes with the complication that their metal 3d printer may not be able to use the materials ideal for it. You still end up with some solid metal between the water and the cpu, even if using a liquid metal medium between the cpu and the cooler itself, that solid metal replaces the lid as the hard cap (infact without seeing the materials used in the current cooler and the lid, it may already be the hard cap) . The only way around that would be running an entire liquid cooling setup full of the liquid metal and making a sealed enclosure around the cpu, but that comes with the seperate issue of ensuring your liquid metal is non-conductive of electricity, exceptionally conductive of heat, and not even slightly corrosive under high pressure, oh and cheap because your going to need several gallons of it.

The systems I worked on could maintain temp even with no heat load on the system. Pretty cool to see one of these get out into the wild.

Its pretty neat seeing that chiller outside of where i work. We have ran many of them for years for things. The valve on the back is a bypass valve to control pressure. Be sure to press the arrow down button and tune it. They can reach in excess of 85psi water pressure.

I have to make my insane gratidute for everything LMG does known. I mean I couldn‘t care less about some fancy cooler. But somehow the incredible video team and Linus manage to produce videos that are sooo fun to watch and have such good production quality. I‘m so thankful everytime we get a little look behind the scenes it baffles me time and again too see the amount of effort poured into making these videos!

[@skyman3]

Great video. I'm so glad you guys have this chiller now! With all the stuff Linus has bought recently, I can't believe it has taken this long to get a chiller like this (and it was only because of "John"). Those "gas" valves are labeled on the side (7:07). 600 WOG. That stands for 600 PSI rated water, oil, or gas. You can use that valve for water, oil, or gas. It should be noted that it may not be lead free, so while WOG means you can use it on water, you may not want to use it on a pipe that someone will be drinking or cooking from. All this is true in the USA, so I imagine it's mostly true up North a little ways as well. Also, I love the "cause that to go erect" with the high pitch engineering laugh shortly after. "You know what's fantastic Linus? We cannot kill ourselves with this, mostly" is a close second.

[@patemathic]

0:19 The way camera started pointing towards Alex after Linus's introduction in a cooling video - is absolutely epic

[@Avboden]

I could see this thing actually being useful for the lab. Absolutely normalizing the fluid temps to test the maximum-balls-to-the-walls settings on devices is interesting.

[@jomeyqmalone]

This is a big improvement over the way we cooled the laser at my first job, which was to hook up the water inlet to a utility sink in the next room, and the have the outlet just drain out a hose into that same sink. Every morning I had to turn on the faucet enough to cool the laser, while checking for a little bit to make sure the sink wasn't filling faster than it could drain. At the end of the day I had to turn off the laser, and do the process in reverse. Not exactly a gold star for conservation.

[@nobodynoone2500]

Yikes. a big tank and a pump would suffice. Total loss systems are messed up.

[@grandinosour]

Many large ice making machines work this way...water in to cool the condenser and then out to the drain.

[@giamonioz]

6:51 If the valve says 'WOG600,' it means Water, Oil, and Gas at 600 psi, even if it's color-coated for gas. So it's okay :)

[@Alpakka91]

My mother-in-law still has a pc with the first cooler you showed in this video. I had to change it to a bigger cooler and fan, because the original started making noise. Now it makes more noise, but more consistent :D

[@Hazdazos]

Episode idea: try different materials for your water block to increase thermal conductivity. Copper is at 4.0 W/cm K but silver is at 4.3 W/cm K. Make one expensive silver water block and see if you can draw more heat off a processor.

[@lemagreengreen]

Great idea, silver is expensive but cheap enough to justify that experiment. How much do you think you would realistically need? I've never seen anyone machine silver.

[@Hazdazos]

@@lemagreengreen silver is about 100x the cost of copper so clearly expensive, but within the realm of possibility for the LTT organization. Plus it's not like it would go to waste - just remelt it and sell it. You wouldn't want to machine the silver, make a mold and pour it. Maybe grind a few thousandths of an inch off the mating surfaces for a better surface finish and thus better thermal transfer. Get this idea to Linus because I think it might be a cool project.

[@sithus1966]

@@Hazdazos I bet they could find a subscriber out there somewhere that is also a jeweler that would be willing to take on such a task.

[@im.thatoneguy]

I suspect the better approach is no-material. Copper conductivity might be low, but grinding down to almost nothing is even lower. Silver is so soft that I would guess you would need more than 10% thicker.

[@pirojfmifhghek566]

The only way to go up from here is to de-lid. Would be really interesting to see the results though.

[@Jrscustoms]

theoretically since you applied the cooling via a mini split (in a past video), you could cool a pc with a 3-ton unit using copper lines to cool your pc, currently i'm doing a build in which normally a furnace would have all its essential needs in it, but ripped out completely, mounting all your pc essentials on a back plate of sheet metal and pulling those copper lines straight from the evaporator coil sitting on the furnace case to your cpu & gpu, and back out to the ac unit, no fans would be needed since you could cut an opening in which the blower motor shoots air thru all the components, all you would need is a call of 24v to the out door units contactor to signal the ac to turn on and either a temp sensor or a relay to tell the ac when to stop, lol it may not be price efficient but its for shits and giggles.

[@mrsparefox3704]

I have about 5 of those chillers at my job that were scrapped. Never been used. I always though about using one but the power draw is insane lol.

[@nobodynoone2500]

The peak draw is huge, but unless you are sinking 5000w of heat into it, the long term draw is much, much smaller, and mostly from the big coolant pump.

[@StevieJayGamez]

I’m an hvac technician. I’d like to make a suggestion. Build a chamber with gaskets out of Plexiglass. Add service access ports and pressurize it it pure nitrogen to test for leaks. Put a pure helium and maybe nitrogen mixture in it. The helium as with hard drives creates less drag. Then you can should be able to maintain a moisture less environment. Then you can add a cpu cooling evaporator and a evap with variable speed fans. You will be able to cool every thing in a pure environment. That and didn’t change your txv out to one that can handle sub zero temps? Real cryogenic freezers use a different refrigerant for process cooling. Or you can do a geothermal geothermal heat pump to provide 50°F water. Either that or get a mini chiller and go with hydronic cooling Also it depends on your sensor location, typically most people move their txv sensing bulb to areas where the most ice builds .

[@DarthJenow]

If you want to go complete over the top, try to get your hands on a Huber Unistat. They go down to -120 °C (depending on the model) and have an accuracy of 0.01 °C

That's a giant pain in the ass for PC computing bc you'd have to figure out a dew point detection system that regulates the output of the cooler, otherwise you risk shorting the entire PC due to condensation

The chillers used in the tool for the lens, stage, and many parts that need stable temperature control for sub micron registration, uses chillers with much tighter temperature control by an order of magnitude.The temperature controller uses fuzzy logic to maintain the temperature within 0.01 degrees C. Among other rebuild tasks, I rebuild those as when they run 24/7 the pumps, valves, controls, and compressors wear out.

Thank you for letting me realize that dream through you. Probably not so great that you put it in my head that's its actually feasible and a good(?) idea....

[@Bloodface1989]

How rapidly Linus unzipped the temperature display sticker without emotions broked my heart 💔

[@KaminKevCrew]

It’s also worth noting that because the coolant was sub ambient, the radiators in the computer would have actually been adding heat to the coolant, since all they do is help hot areas (in this case, the air) dissipate their heat into cold areas (in this case the coolant). Not that it makes much difference, since the temperature delta would have been relatively small, and the cooler can definitely handle the extra load.

Thanks for the video. I am confused by the CB23 scores, though. A stock (!) 5.5/4.3 13900K does 40k+ scores at about 290 W. Depending on your cooler you might hit the 100°C temperature limit before that, but an Arctic LF2 420 keeps it just on the edge of *not* throttling. At 253 W power limit the stock 13900K does 36k+ scores. Undervolted you can get stable 40k+ scores down to 240 W (or lower) depending on your CPU sample. At this wattage an Arctic LF2 420 keeps the CPU below 85°C without even having to run max fan rpm.
