sorry linus but the info on the how the coller works is wrong. what you call a sensig bulb is the filter that removes moisture from the refrigerent. and the cappeleri piping is the expansion valve that regulats the refrigerasjon. the reduksjon in the inner diameter is what creats a reduksjen in the boiling point.

Sketch hardware makes for some of the best LTT videos. It's either worse then anyone thought and makes for a hilarious video, or they run across a rare gem that's just cool to see.
am i crazy or does this cooler actually seem to be not that janky? i mean if they just included the electrical panel that the boys needed to get, this just seems like a very functional solution. mind you, that cooler is dumping heat in the room and obviously in a wide open area like their workshop it isn't noticeable, but it would be if you're in a smaller closed area.
I'm an HVAC Technician. Your explanation of the refrigeration cycle is explained better than all of my coworker's "customer-level explanation." Also, that grease or whatever and foam to prevent condensation is genius. I always thought of converting a window AC unit into a CPU cooler, and my idea of preventing condensation was creating a perfectly air-sealed case, pulling it into a vacuum, and then filling it with dry nitrogen haha
what if you also cool the inside of the case to negative temp? then you wont have condensation around the cpu block but only on the pc case walls and you can easily drain it
I've often thought about an AC cooling for my computer, too, but not to make it really cold, but to bring the heat outside my room, with the AC unit being outside my window. keep the temp of the liquid at about room temp to avoid sweating. Not sure how accurate it would be though.
That would be a fun project. I do wonder what sized cap tube one would use for that. I do see possibly issues of short cycling the compressor depending on how you control the system. The system he is using is equivalent to about 1/5 ton (according to ye ol interwebs conversion) so even with a small wondow ac we are above that. A larger reservoir would solve that by having a larger volume to cool so we could run fewer cycles but longer ones. With that we could make the unit work like a glycol chiller where the evaporator is placed inside the reservoir. As for controlling the temp any off the shelf 120v digital temp controller for a reach in cooler would work. What I dont know is pc water cooling so I dont know if we can put a glycol water mix in it. If we can we could cool that well below freezing
After watching Technology Connections explaining how a heat pump works for what feels like 30 times, now I get to see LTT explaining it! Great job explaining it in a few minutes!
This actually caused a bit of a dilemma for me. I already knew about heat pumps thanks to Alec, so I wanted to watch the gameplay, but the "zoomer retention" made me feel guilty.
Refrigeration guy here. Impressed with the explanation of refrig cycle, FYI. Theres no sense bulb, or expansion valve in this system. This is "fixed orrifice" and that cap tube is the "metering device" the flow rate is fixed, vs a thermal exansion valve with a sensing bulb, is self adjusting and varries the refrig flow for efficiency. The bulb here is a filter drier to remove moisture, otherwise said moisture freezes in the cap tube, plugging it up.
Im so surprised, this build is actually decent. Somewhere in the beginning it looked like they were going full jank like usually. But this actually turned out as something you could sort of actually use
@@gags730i wasn't talking about the cooler itself being janky. I was talking about the entire build in general. Usually the concept is, alex "prepared" some cooling project, then alex and linus build and a dozen of things go wrong, which they then fix with duct tape and ty-wrap kinda solutions that sort of work. And the final thing is just a heap of garbage that needs lots of adjustments and like doesn't really reliably run at all, but only works because like 3 skilled technicians are paying constant attention to things. This project looked like it headed that way, but they actually managed to create a decent thing
@@hotwings9382downfall? Idk where you are looking, but I'm not seeing downfall anywhere. They are still making fun tech content, still getting over a million views on every video, still have sponsors on every video. All i see is a very healthy channel
@@MATT.04 to me that's the fun of these videos though. Part "here's why no one bothered making a commercial version of this" and part "how far can we push this ridiculous idea"
@@gags730 i think the reason for this jank has mostly to do with time. They take a certain amount of time to shoot the project. And then, when faced with problems, they decide to go for the quick and simple solution, rather than a proper one. Which makes sense as they tend to take the whole thing apart as soon as the video is done anyway. The goal is to showcase concepts and crazy theoretical ideas, and how they could be made practical, and how they would perform. Their goal is not to build a reliable system that's properly built. They are doing an experiment, not building professional grade infrastructure
As a certified refrigeration technician. The "capillary coil" is actually called a capillary tube and that is acting as the metering device to feed refrigerant at a constant rate. The refrigerant is still in a liquid phase after the capillary tube and it becomes vapor when heat is absorbed from the water. If no heat is absorbed you will have liquid feedback to the compressor which will kill a compressor. Loved the video, just figured I'd chime in
Thank you, thank you very much, thank you. 15 years ago, I modeled a project in drawing about this type of cooling, and I always looked for someone who could motivate me and I never found anything similar to my ideas. However, today, you fulfilled a childhood dream of mine. Eternally grateful for building my dream and showing that it works, one day I will be able to build one. Thank you very much . A simple Brazilian, but forever satisfied, Thank you.
Chem Eng student here, COP is coefficient of performance; it’s basically just a ratio between useful heating to work. Also, thought Linus’s description of the refrigeration cycle was really good! Wish my lecturers explained it to me like that the first time I was learning about the carnot cycle.
I doubt that what manufacturer meant, ever seen real life chiller with cop of 650? ; ) They most likely meant cooling power since its supposed to be able to take 600w load, just AliExpress things ^_^
Yeah but that's sketchy, 650 COP is technology from maybe the year 3023, even 6.5 is a lot for such small compressor, and I never heard of changing the COP to change the output power , I think its just controlling the cooling power as 650W sounds close to the 600W advertised, and COP will stay more or less the same, maybe less efficient toward the higher power values.
@@sznikers it does, however, make it doubling confusing in a refrigeration context haha. It was my first thought too until the casual 650 lmao. Just AliExpress things indeed.
@@Aybex97 I assumed 6.5 personally, happy to be told I’m wrong. However adjusting the power effecting COP isn’t unheard of on small compressors. 6.5 is pretty high for something this size, but then again in my work, and studies I deal with compressors at an industrial scale
There needs to be a part 2 of this video with constant temperature feedback controller installed, problems fixed permanently (sound proofing?) and turned into an actual primary use computer its too good to be an experiment
They already have a controller installed. It uses pressure to regulate temperature and I would argue that they do not need any more equipment to set that chiller to a specific temperature range using cut out pressure(the COP they were talking about) and the CIP(cut in pressure) that they never discovered on this unit.
This was actually one of the best videos ive seen in a long time. Cant even tell you why, was just really good. The PC was the right amount of janky - functional and successful without being over the top, or the polar opposite of being a total jank-fest.
For real, it even feels like the thrust of this video is that cities skyline is insanely hard on your machine which is... An interesting marketing strategy
Ask Nerdforge to make a shell to cover the chiller in a style that matches the pc case and it will look fantastic, but that's if you plan on keeping that case equiped with it.
I love these ~30 min videos. I love seeing all the little struggles and wins along the way and also just the guys talking about all the things they had to learn to do to get the project to work. It feels like all your best videos from the past and I hope these vibes stay with this channel! Thanks!!
I loved the refrigeration loop explained. It was the closest to correct I've seen in a video like this. The sensing bulb he called out is actually a liquid line filter/dryer, but that's the only thing i saw described incorrectly.
No expansion valve on a capillary system, pressure drop occurs in the cap tube, skips over the fact that the evaporating liquid refrigerant is what absorbs the heat and skips straight to saying the vapour becomes superheated, etc. He did pretty poorly on this tbh.
@@nathanwildman6404the video is right for the majority of viewers. Getting to technical for the majority will mean less continued watch time for them. They have to balance it, they could explain the whole thing in detail but that's going to bore the vast mass of LTT but other channels that are for in depth analysis building would. Surprised they didnt pop up a diagram for for 5 seconds which showed how it worked but for LTT this is just right
@@nathanwildman6404 I'm just glad they tried. Could've skipped it all together and said let's see if this stuff can make it run cooler. And yeah, if they want too in depth it would just bore people, like the guy below said.
I feel like Alex should know this, given he is a mechanical engineer. Active cooling is a part of the thermodynamics module taught to mech engineers at my uni at any rate
The way he explained it was just a basic controller. You can't control COP by "up/down" control. I think Alex knows what COP is but in this application it's not the coefficient of performance as you can't just increase that at the press of a button.
So this is what i need to stop my 4090 boiling me alive when playing Cities Skylines 2!! Alex, hook me up 😅 Edit: looks like you need someone to fix your traffic for you too. Just give me a call 😊👍
you will boil even more with this if you dont put it outside your home. The chiller uses power itself, and the laws of thermodynamic say that the amount of heat in your room will increase by how much your computer + the chiller dump into it. The best way to not boil is to not use high TDP components, or have good airconditioning, or both.
hi guys i work with chillers and had a wow idee if you can get a air tight case and pump dry nitrogen in that will solve all your condensation probs and if you use glycol not water you can go to sub 0 we have systems in South Africa running at -30 C° and will not ice up when you use glycol and not water. Dry nitrogen will displace all the moisture in the case so no condensation can form. love your content.
Alex's "I made these nice little L brackets here out of couple L brackets" made me think of Dave the Barbarian's "Dave constructs a homemade megaphone, using only some string, a squirrel, and a megaphone".
and a biggg reservoir to keep a gallon of water at freezing to combat heat soak in long power draw situations. * apparently will help keeping the AC from cycling as much once they get a temperature probe to cycle the compressor.
i love that this is one of the least sketchy chillers in the channel so far also Andy's reaction to the in-game camera is a pretty strong selling point
It's been a long time since I seen this kind of video from LTT. Liked the format before. Love it now! Much more... Human, far less corporate / money oriented. Nice turn back in time to your early days.
Errors in video: 1) That is a capillary chiller. There is no sensing bulb or expansion valve. That would be for a TXV which is not a part of this chiller. 2) The "power" of the compressor controller is the frequency in Hz. It's a mini 3 phase compressor.
Would love to see you guys run some of these chillers at just above the dew point. It would be interesting to see you guys set up a system that automatically sets that.
me to, they look a realy cool add on , if could a little smaller, and a lot more finished, or at least list part needed to finish it to working cooling system, but they did send out extrea parts needed to get it going? 66%, ould looked into why 66%,
the UART input is kinda cool. you can make a serial port control that (many boards still have a serial header, at least all my b550s still do) that means you could in theory hook this into something like AI suite or a similar software assuming you can make a translation layer and said software has an api available
I'm pretty sure those Intel Cryo Coolers used UART with usb to serial. Wonder if you could steal the control board out of one of those (though the software might need some tweaking to a accept phase change cooler instead of a TEC) Edit: yup, it's a Silicon Labs CP210x USB to UART interface in the cryo coolers
You could just program an Arduino or Rpi Pico to listen to a fan PWM header on the motherboard and control the cooler accordingly. That way it works in any OS but you can also tune the cooling curve in software.
I wonder if the Zoomer Retention segments actually show a statistically significant increase in attention retention. I think it'd be awesome if you guys made a video about the statistics involved with a TH-cam channel at the scale of this one.
I always wanted to try to build a hermetically sealed case with pass thru for liquid cooling and fill the case with nitrogen and silica packets to avoid condensation for a 24/7 sub ambient build. Maybe use something fun like vodka for the loop so you can go below freezing. (Pure ethanol freezes at -114C (-173F) but carries less thermal energy so vodka is good mix)
You mean Linus jumping on an internet controversy to push views? CS2 runs like ass, it *still* runs like ass on the janky rig with top of the line components
City Skylines 2 is insane the detail is awesome. Gone is the cartoonish look now it looks real. Problem is now everyone’s PCs are going to catch on fire lol.
CitySkylines 2, low fps ,because they made, that part of main CPU calculations does GPU now and there is no way to change it in game. Better they should leave CPU tasks for CPU, especcially with nowdays multicore CPUs, and GPU for graphics. Kind of big performance design fail for this game if not the biggest when you get 20fps @ 4K with 4090.
@@nem3thThat is just not true, idk where you did you hear that. GPU is not doing any simulation calculations, that would be ridiculously tricky to sync up with the CPU. The reason its getting 4090 to its knees is because a lot of the rendering is not optimised properly yet. There are ridiculous sampling rates on some of their effects like Depth of field that eats 40% of the framerate because it samples the whole screen every frame and applies the blur, while way less is actually needed for the same effect. This is why people cannot run this properly on 4K.
@@nem3th IDK why absolutely NO ONE in the comments mentions the fact that the game simulates INDIVIDUAL TEETHS for all the npcs in the streets , no matter how far you dezoom, without a L.O.D setting to stop it from afar.... The fact this game lags is not because of it's awesome sense of detail, complexity etc etc but because of the shittiest optimisation, tells you everything you need to know about modern AAA games.
I used to have a vapochill lightspeed unit. I did quite a bit of prep with that. Masking the memory sockets and spraying the whole board in a dielectric grease. The board had to be left over night. The vapochill also came with a heater element to fix to the rear of the motherboard to help with condensation. It wasn't a water chiller, but instead you had a fat tube with an evaporator head you mounted to the cpu. The mount needs to be seriously tight, more so than a water block. Idle temps were around -40-50c if I remember and would hit -15c at full load with a qx9650. It was a fun build, but noisey as hell and impratical for long term usage. Even with the prep, all the necessary neoprene insulation, condensation after a few weeks would be an issue.
I just have to say this has to be one of my favourite LTT videos of all time. Just insanely fun to watch and the Alex-Linus-synergy just never fails to amaze lol edit: spelling
Just have to make sure it won't corrode any of the components. That's the reason there are so many different types of antifreeze - they're based on the material makeup of the components in the vehicle they are to be used in.
Mechanical Engineering student here... CoP is "coefficient of performance". It is a value that represents the efficiency of a heat pump/AC system. It's calculated by the heat output from the condenser (typically Q) compared to the power supplied to the compressor (W). Basically tells you how well of a job cooling per input power it is doing.
COP should never be as high as 650 though. I've never seen anything higher than like 8. It's typically not a variable that can be so finely tuned on the fly so it doesn't make sense to just "set" the COP to some value.
If I had to guess, that figure would more likely mean the cooling capacity measured in Watts, considering the heat pump is advertised als having a cooling capacity of 200-600 Watts. It could also be interpreted as a COP of 6.5 if the compressor draws ~100 Watts, but that wouldn't make sense as you said as COP isn't a variable to be set.
I have been thinking, how would such a chiller work on a pc. And it works. And i guess with automatic sensors you can program it to stay above the condesation point. Would be ideal for in the summer.
@@PascalBrax Use one of those exhaust mounts you have on regular portable AC-units. A chunky hose from the exhaust on the chiller to a mount on your window that also seals all the air gaps. I have a Electrolux portable AC and it have on of those accessories. That way all the cool air stays inside and the warm air goes outside. If you then also cool the GPU and therefore cool the ambient temperature inside the case (if everything in there is at around 10 degrees celsius), and have some exhaust fans on the case your computer could potentially double work as an AC in the summer haha
haha that was so funny seeing andy go geek over all the camera settings in the game. "why cant our camera do that?!" game looks really epic, and that chiller seems to really do what they claim it's gonna do! badass
Lovely to see this, even more interested to see the next iteration of this build, like a compact mini chiller built into the case. It could probably be a product idea {hope case manufacturers are listening} cases with pre built chillers.
Yeah, I was thinking about making an LTT forum post about that. Beam's super easy to setup as a CPU stressor: Each vehicle uses 1 thread. If you want more load per thread, use bigger vehicles. Or you could also just run the built-in benchmark and see what score you get.
Distant Worlds 2 is the best I've seen yet. if they get a good late game save and disable the CPU usage limiter, it will pull 100% cpu usage no problem
@@pigeondriver8992 I have a 3950X and have seen how the game utilizes each thread. Both my previous i7-7700 and my friend's 4790K would run 5 - 7 cars before being extremely slow. Windows itself will use 1 or 2 threads, and DX11 also runs on its own thread (which often ends up being the bottleneck).
It drove me nuts. Do they get to a point where it's a joke? I was 3 minutes in when I paused it to scroll down to see if anyone else was complaining. they're not. I win the oldest man award today. I might only be 35 years old physically but I'm at least twice that on the inside.
I absolutely hated it, while I understand doing it as a bit, it shouldn't be for the whole minute. It was so annoying seeing movement in my peripheral vision.
The "gameplay for zoomer retention" really bugged me. I couldn't pay attention to what Linus was saying as that kept drawing my attention. I hope this was an experiment that will not be coming back.
Phanteks put the bottom of the case at an angle for better airflow from the side without significantly increasing the height of the feet. And it looks cool.
So I have an idea for Alex in the future. There are these things called dry rooms. Basically the idea is to remove all humidity from an area. If you could build a mini dry room then build a pc inside of it and subzero liquid cool it then you shouldn't have issues with moisture build up. You might possible be able to cool to sub zero without any protection on the board or cpu.
Just close the case and circulate the air through radiator connected to the chiller loop. That would keep the air in the case cool and dry (it would require a liquid cooled GPU, though)
COP (Coefficient of Performance) The Co-efficient of performance (COP) is an expression of the efficiency of a heat pump. When calculating the COP for a heat pump, the heat output from the condenser (Q) is compared to the power supplied to the compressor (W). COP = |Q| W. For the lads wondering what COP is.
I hated that part, it actually me that part unwatchable for me and I had to skip. :| Some random flashing shit on the side of my eye really triggered my eyes/brain in a bad/uncomfortable way.
i have actual adhd and ironically for me it made the whole part of the video literally unwatchable, i didnt understand a single word of what he explained
It probably uses a common NTC 10k thermistor for temperature sensing. (negative temperature coefficient, 10k ohm) Lots of fans controllers use them. You can also get aquarium chillers that'll do the same thing but are self contained with a pump. You'd have to use your own PID controller to get the temps that low.
I genuinely love the video's where Alex and Linus start of with a somewhat logical plan/build and it slowly devolves into the jankiest thing I've seen, but works out lmao. The moment I see glue, tape and AliExpress products my attention is unshakeable 😂😂😂
Watching this video just keeps reminding me how much I wanna see all the old projects like this revisited. I'd love to see 7 gamer one CPU looked at again with newer software and/or hardware. Even going back over this build would be great
C.O.P stands for the coefficient of performance of the chiller. It's not 650 but rather 6.5 (probably, it is the ratio of absorbed heat to work into the compressor. The efficiency of the refrigeration unit if you will.
That’s usually what COP stands for, but I don’t see how that makes sense here. You can’t just magically increase the efficiency, it depends on the hardware and environmental conditions. They’re just making the compressor work harder.
I think in this case it's abbreviated "COmpressor Power", since it's a variable-speed DC compressor, and the range it turned on matches decently the advertised power range.
@@fixminer9797 I will disagree with that. You actually can change the efficiency. Keep in mind it is not compressor efficiency but rather cycle efficiency with a term using compressor work. So for example you could change the COP of the system by adjusting the expansion valve.
Seriously, they have a problem, it should not be catered to. They should be finding out what is wrong with their brains that they can't focus for 30 seconds straight.
You should consider using some cooling liquid other than water when going subzero. Freezing inside the evaporator will damage the cooler and potentially release the gases into the atmosphere. Bioethanol is pretty cheap and will do the trick. That said, love the crazy cooling videos with Alex :D
@@Eute83 If you use high content alcohol, having a %40 alcohol to %60 water, according to some forum, will reduce freezing to -20°c, or -4°f. I imagine you can use whatever form, be it vodka, moonshine, or isopropyl, as long as there's nothing else in it such as flavoring.
Fixed orifice metering devices like capillary tubes don’t use a sensing bulb to adjust refrigerant flow. That is not a sensing bulb, it is most likely a filter drier seeing as it’s on the refrigerant liquid line. There is multiple ways we could improve upon this design, one would be an inverter style compressor and ECM style condenser fan that ramp up and down depending on demand
Yes you can but mineral oil is harder to move around in a loop than water and a pain to clean up. Virtually everything it comes in contact with will stay oily.
I think oil gets more and more viscous as you cool it, so it might not move fast enought for proper heat exchange... then again a more powerful pump might help with it. I want to see it either way!
@@Inimigor1well, they did do water-cooling with a 2.5HP gas powered pump if I recall, that should get some oil gunk flowing... Adding whole new layers to the term "suicide run" 😂
▫️This was excellent - riveting, interesting and greatly informative. I’m a Cities: Skylines and SimCity (yup, I still enjoy it) genre fan (no pun intended), too.

You guys are awesome, delightfully entertaining, and so “cool” in what you do. Thank!
"Why can't our camera have those ?" "Alright aewoe awoe geow comn geaow awy" Stingy as hell, as any man should be. Got me rolling on the floor. At 22:49
Your cooling cycle explanation is spot on, but that chiller does not have an expansion valve so what you described as sensing bulb is just the dryer. The capillary tube acts as expension valve in those cheap units which limits their efficiency.
@@TehButterflyEffect Not true at all, you have been able to get vastly better temps on intel on skylake at the very least. probably still today, I haven't kept up though.
Editing team did a great job on this one. I liked the clips when mentioning previous builds. The zoom on current topic. The flow of the build felt good. Great job editing team!
These things look like a good idea for a campervan AC. Very compact. And you don't need much more than a couple of 100W cooling power. Operated off 24V is also perfect!

@@gags730 i think the reason for this jank has mostly to do with time. They take a certain amount of time to shoot the project. And then, when faced with problems, they decide to go for the quick and simple solution, rather than a proper one. Which makes sense as they tend to take the whole thing apart as soon as the video is done anyway.
The goal is to showcase concepts and crazy theoretical ideas, and how they could be made practical, and how they would perform. Their goal is not to build a reliable system that's properly built. They are doing an experiment, not building professional grade infrastructure
As a certified refrigeration technician. The "capillary coil" is actually called a capillary tube and that is acting as the metering device to feed refrigerant at a constant rate. The refrigerant is still in a liquid phase after the capillary tube and it becomes vapor when heat is absorbed from the water. If no heat is absorbed you will have liquid feedback to the compressor which will kill a compressor. Loved the video, just figured I'd chime in
Am I crazy or is this the first time in a long time we get an actual animated LTT intro

Thank you, thank you very much, thank you. 15 years ago, I modeled a project in drawing about this type of cooling, and I always looked for someone who could motivate me and I never found anything similar to my ideas.
However, today, you fulfilled a childhood dream of mine. Eternally grateful for building my dream and showing that it works, one day I will be able to build one. Thank you very much .
A simple Brazilian, but forever satisfied, Thank you.
The Alex cooling videos get more and more anxiety inducing. It’s like, instead of Fast and Furious, he’s Lanky and Janky
😂😂😂😂
FYI that "sensing bulb" is called a filter drier. it's purpose is to remove contaminants and moisture before feeding through the capillary tube
yeah the capillary tube is the metering device there is no thermal expansion value in that system
Ha ha yeah I cringed just a bit with his refrigeration explanation but I gotta give him props for trying!
@@HVACRVIDEOS You must have an alarm for someone explaining hvac badly 😂
@@HVACRVIDEOSI went to the comments to shout out your channel. And there you are already 😂 Have a good day sir!
Chem Eng student here, COP is coefficient of performance; it’s basically just a ratio between useful heating to work. Also, thought Linus’s description of the refrigeration cycle was really good! Wish my lecturers explained it to me like that the first time I was learning about the carnot cycle.
I doubt that what manufacturer meant, ever seen real life chiller with cop of 650? ; )
They most likely meant cooling power since its supposed to be able to take 600w load, just AliExpress things ^_^
In this case it its probably something like COoling Power, COmPressor speed because that seems to be what is being adjusted by that setting
Yeah but that's sketchy, 650 COP is technology from maybe the year 3023, even 6.5 is a lot for such small compressor, and I never heard of changing the COP to change the output power , I think its just controlling the cooling power as 650W sounds close to the 600W advertised, and COP will stay more or less the same, maybe less efficient toward the higher power values.
@@sznikers it does, however, make it doubling confusing in a refrigeration context haha. It was my first thought too until the casual 650 lmao. Just AliExpress things indeed.
@@Aybex97 I assumed 6.5 personally, happy to be told I’m wrong. However adjusting the power effecting COP isn’t unheard of on small compressors. 6.5 is pretty high for something this size, but then again in my work, and studies I deal with compressors at an industrial scale
There needs to be a part 2 of this video with constant temperature feedback controller installed, problems fixed permanently (sound proofing?) and turned into an actual primary use computer its too good to be an experiment
They already have a controller installed. It uses pressure to regulate temperature and I would argue that they do not need any more equipment to set that chiller to a specific temperature range using cut out pressure(the COP they were talking about) and the CIP(cut in pressure) that they never discovered on this unit.
paradox interactive can’t afford another video 😭
their fans hate them (unjustly imo)
This was actually one of the best videos ive seen in a long time. Cant even tell you why, was just really good. The PC was the right amount of janky - functional and successful without being over the top, or the polar opposite of being a total jank-fest.

they fixed the performance with todays patch
I love how in these build videos alex 70% of the time defaults to "we'll just use zip ties"
10:04 I have been summoned!! 👻
Ask Nerdforge to make a shell to cover the chiller in a style that matches the pc case and it will look fantastic, but that's if you plan on keeping that case equiped with it.

@@TypausZuendorf Nope actually
Everybody hold onto your papers?
The sarcasm in these videos with Alex and Linus makes this the best tech videos out there. Damn i love you guys 😂😂😂
I loved the refrigeration loop explained. It was the closest to correct I've seen in a video like this. The sensing bulb he called out is actually a liquid line filter/dryer, but that's the only thing i saw described incorrectly.
There was a few other inaccuracies but I give him massive credit for his effort!
No expansion valve on a capillary system, pressure drop occurs in the cap tube, skips over the fact that the evaporating liquid refrigerant is what absorbs the heat and skips straight to saying the vapour becomes superheated, etc. He did pretty poorly on this tbh.
@@nathanwildman6404the video is right for the majority of viewers. Getting to technical for the majority will mean less continued watch time for them. They have to balance it, they could explain the whole thing in detail but that's going to bore the vast mass of LTT but other channels that are for in depth analysis building would. Surprised they didnt pop up a diagram for for 5 seconds which showed how it worked but for LTT this is just right
@@nathanwildman6404 I'm just glad they tried. Could've skipped it all together and said let's see if this stuff can make it run cooler. And yeah, if they want too in depth it would just bore people, like the guy below said.
@@HVACRVIDEOS woah its chris!
The terms COP (coefficient of performance) and EER (energy efficiency ratio) describe the heating and cooling efficiency of air conditioners 😊
I feel like Alex should know this, given he is a mechanical engineer. Active cooling is a part of the thermodynamics module taught to mech engineers at my uni at any rate
And that COP in de vid will have been 6,5 as 650 would be physics breaking high lol
The way he explained it was just a basic controller. You can't control COP by "up/down" control. I think Alex knows what COP is but in this application it's not the coefficient of performance as you can't just increase that at the press of a button.
@@nickcramp630 I didn't pay attention that closely. Yea that doesn't make any sense. CoP is generally a function of temperature difference and load
I don't think coefficient of performance is logical in this case though. It could be something like cooler/cooling output power in watts.
So this is what i need to stop my 4090 boiling me alive when playing Cities Skylines 2!! Alex, hook me up 😅
Edit: looks like you need someone to fix your traffic for you too. Just give me a call 😊👍
Hey biffa :)
You should be sweet going into the winter months, think about us poor Australian’s going into Summer!
The map was from Colossal Order, they used it for performance testing and I want none of the blame for the problems in it haha -AC
you will boil even more with this if you dont put it outside your home. The chiller uses power itself, and the laws of thermodynamic say that the amount of heat in your room will increase by how much your computer + the chiller dump into it. The best way to not boil is to not use high TDP components, or have good airconditioning, or both.
hi guys i work with chillers and had a wow idee if you can get a air tight case and pump dry nitrogen in that will solve all your condensation probs and if you use glycol not water you can go to sub 0 we have systems in South Africa running at -30 C° and will not ice up when you use glycol and not water. Dry nitrogen will displace all the moisture in the case so no condensation can form. love your content.
22:36 _"That's a valid city building strategy"_
It's the one used in France. Roundabouts everywhere.
man I love an Alex/Linus video. No matter how much preparation and care they take its always so chaotic and janky. So fun to watch.
Alex's "I made these nice little L brackets here out of couple L brackets" made me think of Dave the Barbarian's "Dave constructs a homemade megaphone, using only some string, a squirrel, and a megaphone".
That's a blast from the past
Would love to see part 2 where you actually daily drives this but with better configurations!
Would be fun to see that chiller in a loop cooling both cpu and gpu! :D
I agree with you
Came here to say the Samething
and a biggg reservoir to keep a gallon of water at freezing to combat heat soak in long power draw situations.
* apparently will help keeping the AC from cycling as much once they get a temperature probe to cycle the compressor.
@@Surms41with a suitable controller you can programme the amount of compressor starts, start and off delay.
@@chappy2121 I assumed so if they didn't go the jank route. I wonder how long they're gonna run that system before adding safety.

Sketchy cooling with Alex is one of the last reminders of good ol' days

It's been a long time since I seen this kind of video from LTT. Liked the format before. Love it now! Much more... Human, far less corporate / money oriented. Nice turn back in time to your early days.
A phase change chiller that works?! nice! Great video everyone!
PS: Noticed Alex's Edison hat! Those boys doing some sweet stuff on them hybrid semis.
2:21 HOW DARE YOU! But also, thanks, I was zoning out
Errors in video: 1) That is a capillary chiller. There is no sensing bulb or expansion valve. That would be for a TXV which is not a part of this chiller. 2) The "power" of the compressor controller is the frequency in Hz. It's a mini 3 phase compressor.
Add glycol to the chiller coolant to prevent freezing. It will also help prevent galvanic corrosion between the different metals in the fittings.
Would love to see you guys run some of these chillers at just above the dew point. It would be interesting to see you guys set up a system that automatically sets that.
me to, they look a realy cool add on , if could a little smaller, and a lot more finished, or at least list part needed to finish it to working cooling system, but they did send out extrea parts needed to get it going? 66%, ould looked into why 66%,
the UART input is kinda cool.
you can make a serial port control that (many boards still have a serial header, at least all my b550s still do)
that means you could in theory hook this into something like AI suite or a similar software assuming you can make a translation layer and said software has an api available
Or use any cheap FTDI if no serial headers are available
It wouldn't use a bare serial header though, since those use RS-232 voltage levels and UART connections usually run at 3.3 or 5V.
I'm pretty sure those Intel Cryo Coolers used UART with usb to serial. Wonder if you could steal the control board out of one of those (though the software might need some tweaking to a accept phase change cooler instead of a TEC)
Edit: yup, it's a Silicon Labs CP210x USB to UART interface in the cryo coolers
You could just program an Arduino or Rpi Pico to listen to a fan PWM header on the motherboard and control the cooler accordingly. That way it works in any OS but you can also tune the cooling curve in software.
The zoomer retention bit was quite funny but wow is it distracting, pure suffering getting through it while trying to listen to Linus
I wonder if the Zoomer Retention segments actually show a statistically significant increase in attention retention. I think it'd be awesome if you guys made a video about the statistics involved with a TH-cam channel at the scale of this one.
I always wanted to try to build a hermetically sealed case with pass thru for liquid cooling and fill the case with nitrogen and silica packets to avoid condensation for a 24/7 sub ambient build. Maybe use something fun like vodka for the loop so you can go below freezing. (Pure ethanol freezes at -114C (-173F) but carries less thermal energy so vodka is good mix)
I'm sure there's a reason why no one has done the dry atmosphere yet, but I really do want to see someone try
@@onebacon_ Exactly

City Skylines 2 is insane the detail is awesome. Gone is the cartoonish look now it looks real. Problem is now everyone’s PCs are going to catch on fire lol.
CitySkylines 2, low fps ,because they made, that part of main CPU calculations does GPU now and there is no way to change it in game. Better they should leave CPU tasks for CPU, especcially with nowdays multicore CPUs, and GPU for graphics. Kind of big performance design fail for this game if not the biggest when you get 20fps @ 4K with 4090.
I don't care how good it looks if I can't play it without gettiung a headache
Except for the outdated ones. They seem to be able to run the game without a problem.
@@nem3thThat is just not true, idk where you did you hear that. GPU is not doing any simulation calculations, that would be ridiculously tricky to sync up with the CPU. The reason its getting 4090 to its knees is because a lot of the rendering is not optimised properly yet. There are ridiculous sampling rates on some of their effects like Depth of field that eats 40% of the framerate because it samples the whole screen every frame and applies the blur, while way less is actually needed for the same effect. This is why people cannot run this properly on 4K.
@@nem3th IDK why absolutely NO ONE in the comments mentions the fact that the game simulates INDIVIDUAL TEETHS for all the npcs in the streets , no matter how far you dezoom, without a L.O.D setting to stop it from afar.... The fact this game lags is not because of it's awesome sense of detail, complexity etc etc but because of the shittiest optimisation, tells you everything you need to know about modern AAA games.
I used to have a vapochill lightspeed unit. I did quite a bit of prep with that. Masking the memory sockets and spraying the whole board in a dielectric grease. The board had to be left over night. The vapochill also came with a heater element to fix to the rear of the motherboard to help with condensation. It wasn't a water chiller, but instead you had a fat tube with an evaporator head you mounted to the cpu. The mount needs to be seriously tight, more so than a water block.
Idle temps were around -40-50c if I remember and would hit -15c at full load with a qx9650. It was a fun build, but noisey as hell and impratical for long term usage. Even with the prep, all the necessary neoprene insulation, condensation after a few weeks would be an issue.
You could make a PWM fan control to chiller UART converter to automate the cooling control!
Super cool project!
That would be so cool! Using the connector already on the motherboard to internally probe temps. 🙌🙌
that actually sounds like a solid idea!
But with no documentation it will be a nightmare to figure out the right command needed to set the various commands
I just have to say this has to be one of my favourite LTT videos of all time. Just insanely fun to watch and the Alex-Linus-synergy just never fails to amaze lol

Compared to Cities Skylines 1 where all camera tools are just mods. The content we can make in CS2 is going to be unprecedented.
@@gilbertplays cs2.... unfortunate name
It is a much better idea to just use regular car antifreeze for these situations. The coolant can drop to -40°C and it will still be fine.
Just have to make sure it won't corrode any of the components. That's the reason there are so many different types of antifreeze - they're based on the material makeup of the components in the vehicle they are to be used in.
i just wanna make my 5950X crap to staph random reboots, so no need for deep freezing
Tbh alcohol would work really well for a short video
Mechanical Engineering student here... CoP is "coefficient of performance". It is a value that represents the efficiency of a heat pump/AC system. It's calculated by the heat output from the condenser (typically Q) compared to the power supplied to the compressor (W). Basically tells you how well of a job cooling per input power it is doing.
COP should never be as high as 650 though. I've never seen anything higher than like 8. It's typically not a variable that can be so finely tuned on the fly so it doesn't make sense to just "set" the COP to some value.
If I had to guess, that figure would more likely mean the cooling capacity measured in Watts, considering the heat pump is advertised als having a cooling capacity of 200-600 Watts. It could also be interpreted as a COP of 6.5 if the compressor draws ~100 Watts, but that wouldn't make sense as you said as COP isn't a variable to be set.
I have been thinking, how would such a chiller work on a pc. And it works. And i guess with automatic sensors you can program it to stay above the condesation point. Would be ideal for in the summer.
"Would be ideal for in the summer" yes, unless you live in the same house where this computer+chiller is, that's going to be a hot boi in summer. 🤣
@@PascalBrax One of the reasons I don't game during summer.
@@PascalBrax split AC
@@PascalBrax "just" have long enough pipes
the chiller is outside the case already anyway
@@PascalBrax Use one of those exhaust mounts you have on regular portable AC-units. A chunky hose from the exhaust on the chiller to a mount on your window that also seals all the air gaps. I have a Electrolux portable AC and it have on of those accessories. That way all the cool air stays inside and the warm air goes outside.
If you then also cool the GPU and therefore cool the ambient temperature inside the case (if everything in there is at around 10 degrees celsius), and have some exhaust fans on the case your computer could potentially double work as an AC in the summer haha
haha that was so funny seeing andy go geek over all the camera settings in the game. "why cant our camera do that?!"
game looks really epic, and that chiller seems to really do what they claim it's gonna do! badass
I thought it was part where he puts his hands in the air as he walks off was particularly funny 😄
Lovely to see this, even more interested to see the next iteration of this build, like a compact mini chiller built into the case.
It could probably be a product idea {hope case manufacturers are listening} cases with pre built chillers.
Beamng is also very good for CPU benchmarks, it's very "core count intensive"...
agreed, i have a 13900h and spawning more than 15 ai cars brings my laptop to skin vaporizing temps
Yeah, I was thinking about making an LTT forum post about that. Beam's super easy to setup as a CPU stressor: Each vehicle uses 1 thread. If you want more load per thread, use bigger vehicles.
Or you could also just run the built-in benchmark and see what score you get.

gameplay for zoomer retention is the funniest but most accurate thing i have seen in an LTT video hahahaha
Spent a solid 5 minutes struggling to breathe after seeing that part hahah
It drove me nuts. Do they get to a point where it's a joke? I was 3 minutes in when I paused it to scroll down to see if anyone else was complaining. they're not. I win the oldest man award today. I might only be 35 years old physically but I'm at least twice that on the inside.

I absolutely hated it, while I understand doing it as a bit, it shouldn't be for the whole minute. It was so annoying seeing movement in my peripheral vision.
The "gameplay for zoomer retention" really bugged me. I couldn't pay attention to what Linus was saying as that kept drawing my attention. I hope this was an experiment that will not be coming back.
1:15 the og intro is back LET'S GOO
Jesus christ, Linus. Retention footage? Just jangle your keys every 30 seconds like the rest of us.
"Those skyscrapers you added killed traffic" Linus is as qualified as a normal city planner then.
Lol, I love Kyle's expression when he gets absolutely horrified at something Linus is doing or about to do. It is TH-cam gold :)
The part after 2:30 gave me actual brain damage
12:48 As an electronics hobbyist, I approve of the hot glue method.
Phanteks put the bottom of the case at an angle for better airflow from the side without significantly increasing the height of the feet. And it looks cool.
So I have an idea for Alex in the future. There are these things called dry rooms. Basically the idea is to remove all humidity from an area. If you could build a mini dry room then build a pc inside of it and subzero liquid cool it then you shouldn't have issues with moisture build up. You might possible be able to cool to sub zero without any protection on the board or cpu.
Just close the case and circulate the air through radiator connected to the chiller loop. That would keep the air in the case cool and dry (it would require a liquid cooled GPU, though)
@@Papinak2No, too cheap, too simple, I prefer this dry room, more simple, but big boss level, a room full of dry computers maxed computers

COP (Coefficient of Performance)
The Co-efficient of performance (COP) is an expression of the efficiency of a heat pump. When calculating the COP for a heat pump, the heat output from the condenser (Q) is compared to the power supplied to the compressor (W). COP = |Q| W.
For the lads wondering what COP is.

It probably uses a common NTC 10k thermistor for temperature sensing. (negative temperature coefficient, 10k ohm) Lots of fans controllers use them.
You can also get aquarium chillers that'll do the same thing but are self contained with a pump. You'd have to use your own PID controller to get the temps that low.
I genuinely love the video's where Alex and Linus start of with a somewhat logical plan/build and it slowly devolves into the jankiest thing I've seen, but works out lmao. The moment I see glue, tape and AliExpress products my attention is unshakeable 😂😂😂
Watching this video just keeps reminding me how much I wanna see all the old projects like this revisited. I'd love to see 7 gamer one CPU looked at again with newer software and/or hardware. Even going back over this build would be great
C.O.P stands for the coefficient of performance of the chiller. It's not 650 but rather 6.5 (probably, it is the ratio of absorbed heat to work into the compressor. The efficiency of the refrigeration unit if you will.
That’s usually what COP stands for, but I don’t see how that makes sense here. You can’t just magically increase the efficiency, it depends on the hardware and environmental conditions. They’re just making the compressor work harder.
I think in this case it's abbreviated "COmpressor Power", since it's a variable-speed DC compressor, and the range it turned on matches decently the advertised power range.
@@fixminer9797 I will disagree with that. You actually can change the efficiency. Keep in mind it is not compressor efficiency but rather cycle efficiency with a term using compressor work. So for example you could change the COP of the system by adjusting the expansion valve.
@@HydrarDraconis I'm wrong. Good point. Thanks for the response.
Great project! Though the Zoomer retention gameplay is very disturbing for us, older folks.
Seriously, they have a problem, it should not be catered to. They should be finding out what is wrong with their brains that they can't focus for 30 seconds straight.
@@Scribblescrabble0not everything is about you 🤷♂️
You should consider using some cooling liquid other than water when going subzero. Freezing inside the evaporator will damage the cooler and potentially release the gases into the atmosphere. Bioethanol is pretty cheap and will do the trick. That said, love the crazy cooling videos with Alex :D
Can you use vodka or some other hard alcohol?
@@Eute83 If you use high content alcohol, having a %40 alcohol to %60 water, according to some forum, will reduce freezing to -20°c, or -4°f. I imagine you can use whatever form, be it vodka, moonshine, or isopropyl, as long as there's nothing else in it such as flavoring.
@@Surms41 So Everclear 190, then?
Yeah, but wouldn't it start evaporating if it got too hot?
@@thebelpo929 Like in the video, they use a coated tubing to stop any evaporating.
Fixed orifice metering devices like capillary tubes don’t use a sensing bulb to adjust refrigerant flow. That is not a sensing bulb, it is most likely a filter drier seeing as it’s on the refrigerant liquid line. There is multiple ways we could improve upon this design, one would be an inverter style compressor and ECM style condenser fan that ramp up and down depending on demand
As a licensed hvac technician this it true that is a filter dryer

Every time I see a video in which you use a chiller, I ask myself whether you can cool down the oil in a mineral oil PC in the same way
Yes you can but mineral oil is harder to move around in a loop than water and a pain to clean up. Virtually everything it comes in contact with will stay oily.
I think oil gets more and more viscous as you cool it, so it might not move fast enought for proper heat exchange... then again a more powerful pump might help with it. I want to see it either way!
@@Inimigor1well, they did do water-cooling with a 2.5HP gas powered pump if I recall, that should get some oil gunk flowing... Adding whole new layers to the term "suicide run" 😂

Your cooling cycle explanation is spot on, but that chiller does not have an expansion valve so what you described as sensing bulb is just the dryer. The capillary tube acts as expension valve in those cheap units which limits their efficiency.
