My first liquid cooled system used an Eheim pond pump and a transmission cooler with an electrical box as a reservoir, stuffed into a mid-tower case. I still have it! I miss the old days of overclocking and this video was incredibly nostalgic.

[@MattiTuunanen]

My first watercooling was with heater core from an old Opel. Fitted perfectly over the PSU in the old "full tower" style case, where there were plenty of room behind all those 5.25" bays (and I used those excess of 5.25" slots for a tupperware where I have submerged the aquarium pump) ..of course the dimensions prevented me to install that core to roof or back of the case, but having it so that the air path was from side of the case to other side of the case, it worked quite well. Also, when I built that, all the computer fans were like maximum of 80mm, so I got two thick 12cm 12V fans from an old photocopying machine and those made enough static pressure for the core. I dont remember what clocks I got with my K6-2 and my athlons/athlon xp's, but I remember I managed to run my Opteron 185 at 3.35GHz quite comfortably. The tension bar what I used to mount my block was nicely compatible with socket 7, socket A and also socket 939.

[@treborrrrr]

This brings back memories. That's what I used way back when for my first water cooling setup. I built a custom box that I bolted to the bottom of my case to house it, the fans and the pump (Eheim 1046, of course). The waterblock was a Dangerden.. something, I don't remember, but it was just a big ol block of copper. It worked great. It even got featured on HardOCP somehow. And now I feel old thinking about how many years ago that was... ugh.

[@cupuacu4life13]

I always thought people living in freezing places like alaska could just pipe outside air to their pc cases and then pipe out the hot air No extra modifications, just letting below zero air going into the case, but isolating the case from the rest of the room of course, so people dont get their rooms full of freezing air Or maybe even leave the pc separated from the room, kinda like people put the AC evaporators outside of the house, you'd just have the pc out, yes, with protection from the snow and the elements, and stuck very well into the wall so no thief yoinks it out Maybe even build the pc inside of an AC case so people think its an AC when its actually a pc getting infinite free cooling from the harsh polar climate

[@walkinmn]

​​​@@cupuacu4life13ve thought about that too, but you don't want to heat cold humid air from outside inside your PC though, what I have thought about is you just put the radiator or radiators outside but of course you have to protect them somehow from the harsh environment and depending how cold it gets you may want to use antifreeze (also you don't want to let it go that cold). But I don't live in a cold enough place to try this. It could also work if your PC is close to a side of your home that's always colder

Well you can always just use automotive coolant, since a lot of vehicles have cast iron engine blocks, aluminum heads, probably an aluminum radiator and a copper/aluminum heater core… I’ve been using aluminum radiators in my pc’s with EK blocks for several years and haven’t had any problems, plus you can get engine coolant in just about any color…

[@wafu6058]

Give me engine coolant in neon green pastel cryofuel aurora tinglydingly doodad colour and I’ll be impressed

[@NothingXemnas]

As they said, most heater cores today are made of aluminum, as well as radiator and other parts. Steel isn't very reactive with aluminum and overall cuts cost from the engineering side. More than that, the tightest spaces water flows through still are much wider than a computer's water block fin. So much so that my car runs cooling in plain tap water and it has no leaks or cooling issues, and the car itself is 15 years old with only one radiator change due to a car accident ages ago. Also, car coolant is no different from computer coolant; there is no reason to be except for the propylene glycol, since PCs don't get hot or cold enough to need it.

I love building my own water cooling! I even made my own water block out of a chunk of copper back in the mid 90's that I still use today. I used a heater core from a 1984 Escort and an oil cooler. They were stack mounted on the top of the case and run in series. I custom painted the case in red and black diagonal stripes and the interior was painted florescent green with a black light inside and florescent dye in the water. I took it to U of M lan party and everyone was amazed that someone actually water cooled a computer. Good Times!

[@markissboi3583]

[@arjovenzia]

Yep, that sorta setup was very much like my first water cooling setup in high-school. Ganked the core out of a dead Holden at the tip. A very used pond pump, and a beefy 240v fan from some industrial hardware. A water block made in my school metal shop. Reservoir was a tupperware container I stole from the kitchen. All the fittings were irrigation fittings from the shed. The whole contraption was obnoxiously loud. So, installed it in an old At case I cut down to fit the core dimensions. Handles on the top of that and the PC were handles from the car, painted to match. The noise solution, long pipes, and put the noisy box outside my bedroom window. Everyone thought I was insane, your putting WATER in a COMPUTER??! got some insane overclocks😊

[@HorizonOutOfWar]

Let's just stop for a second and appreciate how Linus saved that falling fan like nothing happened at 1:12. Wow.

[@Suaven95]

As a mechanic whos had to force hoses over fittings that were "too big". It is alot easier to boil water and use the hot water to soften the hose and cause it to expand. You get alot more hose to soften and expand at once rather than using a heat gun which only heats one side at a time and can cause the hose to burn. Also stick the Heater core in a freezer or bucket of ice to get it to contract some making the process slightly easier. ***Edit. Also while sticking a smaller hose into a bigger hose you can ensure it not leaking by putting in a hose connector for the smaller hose, then just use a band clamp or zip tie to tighten around the connector

Heater cores are not exposed to air from the outside rushing past them, they are under your dash inside your car and have a fan blowing on them.

[@EvenVangsnes]

heater cores do get air from outside your car.

[@francistheodorecatte]

depends on the vehicle. on a chevy express you can turn the fan completely off on the highway, and the high pressure zone on the cowl area where the fresh air intake is, caused by the chevy express being shaped like a barn, will push almost as much air through the vents as the fan would on high.

[@NeonFlaming0]

He specifically stated that heater core came from a 69 camero. Those cores and almost every core pre 90s take fresh air from outside.

[@trevordubinsky]

[@ikuma8291]

[@gravdigr27]

Before watching this vid I'm gonna say I did this stuff almost 25 years ago. It was the release of the celeron 300a, probably the best value overclocking cpu in history. Capable of a rock stable 50% overclock allowing it to out perform the leading PII 450 costing 10x as much thanks to the celeron's on die cache running at full bus speed vs the PII's larger off die cache running at 1/2 bus speed. Water block was a 5/8" thick copper block cross drilled and plugged, car transmission fluid cooler from the auto parts store for the rad, fountain pump from the hardware store, large plastic electric junction box for a reservoir, and plastic tubing from the hardware store. This setup work well and the over clock was rock stable with reasonable temps. Mobo was an ABIT BE-6II. I still have the homemade water block in a box somewhere in my storage room upstairs. EDIT: No Linus, we did not pull parts from junkyard cars to do this. You can buy these parts new at the auto parts store. And we, or at least the crew I communicated with on the OC message boards at the time, did not use heater cores. We used aftermarket transmission fluid coolers. They were far better suited to the job. We also used fountain pumps due to the afore mentioned head pressure issues. We also used those crazy big full tower cases for these mods. You're in the right church but the wrong pew. You have the right idea but the wrong parts. You also have the wrong idea about why we did this. It wasn't to save money, it was because there was literally no other option. Commercial water cooling kits, not to mention AIO's, didn't exist. So homebrewing your own water cooling was necessary if you wanted to use water cooling. I am literally having brain pain watching you guys do this. For the amazing smart group of people you have assembled there you are doing this all the hard way and it's making my eye twitch lol.

[@anatolklops]

I personally use this type of cooling every day based on two heaters from Fiat Ducato from 1994-2001, bought brand new for $20 each as a replacement for the original. They are denser than yours and both are mounted on top of a homemade case hanging on the wall and cooled by a total of three 20cm fans, 1.5 fans each (left fan is driven by the graphics, right by the CPU and the middle one is the system fan). The whole thing cools like a chimney, because the computer draws air from the bottom and expels warm air at the top, and the 20cm fans are almost inaudible during everyday gaming. Theoretically, if water at a temperature of 90°C were supplied to them, each of these coolers would be able to give 3kW of heat to the environment, so the whole thing has a lot of reserve.

[@lollington_bear]

Next you need to build a shared radiator solution with hot swappable water feeds so that a bunch of PC's (or laptops) can use the same cooling system. The radiator could even be on the office roof.

Should have used a transmission cooler. They come in many sizes and are near identical to PC rads. They come in copper units and some aluminum rads are powder coated inside. They come with the same fitting sizes as PC rads. Have you ever tried cooling with hydraulic fluid or mineral oil while using these rads so you don't have the issue of mixed metal electrolysis? Seams to me it would work as well as water. As long as you used oil resistant parts and hoses.

don't forget the pump would have to be insanely powerful due to how viscous glycol/mineral oil are, plus their specific heat capacity isn't as good as water so increasing flow rate would be mandatory, so that's gonna be one loud-ass pump

I like DIY cooling videos :) Did a DIY watercooling setup for my laptop, the " base station" uses an 12V aquarium pump submerged in a big beer glass, the radiator is a brand new heat- exchanger from a Fiat van because it was cheap, has convinient connections and fits two 200mm Noctua fans. The back panel of the laptop is replaced by a alumium cover that holds down waterblocks over the heatpipes of the CPU and GPU. The waterblocks are in series and quick couplers on the site for easy mobile use, the original air setup of the laptop still functions if the waterccoling isnt connected, I use window washing antifreeze as liquid. Looks awkward but its not stupid if it works :) Those 200mm Noctuas create good pressure through the radiator and the 18W Aquarium pump has way more flow than any PC waterpump could provide. I use some clear garden hose that has strength lining inisde it, that clear stuff Linus uses hear kinks too easy. But I needed to overbuilt it because my waterblocks are touching the laptops original heatpipes and not any heatspreaders directly. But even under full load the temps stay better than the air setup in the laptop could ever be.

this might be the most fun video you guys put out in a while. Not that I'm saying the others are bad, but this one was great! I love these janky custom build videos!

[@kameljoe21]

I have out in my garage an all cooper heater core that is maybe 9 inch by 6 inches by 2 inches thick. Its super small. I got it from a junk dealer many years ago to try a small project where I filled up a old cistern and pumpped water in to that small core to provide some cooling for a small house I had. It worked to some degree and the cistern leaked so it just could not hold the water long enough. I think if I was going to do the project again I would do something entirely else.

1:11 good catch Linus, everybody rags on you for dropping shit so I figured Id compliment your reflex to not allow something to drop, cheers.

I've used 4 row heat exchangers meant for furnaces for DIY pc coolers quite successfully. You can get them for about $60 new and are a lot more adaptable on the fittings portion than automobile bits. Fountain pumps are also quite cheap and accessible; server fans can be had for $20 and provide more than enough pressure (albeit quite loud at full tilt) to push through a chunky cooler, but you can run them either directly off the motherboard or in PWM mode with a controller (the preferred method in combination with a fan curve).

I’d love an “Affordable Water Cooling” video. I’ve wanted to do water cooling but it’s always seemed too expensive to be worth the effort

[@Rock4896]

You guys have been pumping out absolute bangers of videos this week! Hope to see more of this kind of content

[@zeekjones1]

The phrase "nothing's more permanent than a temporary fix" comes to mind when foraging for something that'll work. You just got to embrace the jank, because you know full well that it is staying there. My favorite improper part for the right job, I've personally used, was magnetic filter as a side panel. I could even slide one over to pin a fan between them.

[@jwhitaker81]

Memories of great fun had decades ago. Water blocks made from stock heatsinks and JB Weld. Small engine radiators plastered with 92mm fans were boss. Outdoor water pumps for small yard ponds were what's up. Reservoirs made from PVC pipe and caps. A buddy hard lined his system with CPVC, LOL! Biggest difference was we kept everything but the tubes and blocks outside the chassis and building a proper loop took weeks! We had one Celeron 500 running that ran at 2200mhz. Ah, I so miss the good old days, for sure!

[@jps78910]

Hey LTT, i know im a bit late to this video so this comment may not be seen. I'm a Lead Engineer at a company that produces thermal solutions for Automotive, Industrial, medical and White goods. these include resistance wire heating, PTC heating, and Peltier cooler. a lot of my job includes things like fan selection. A tip which might help for these kind of experiments in the future is on fan positioning. if you place 2 fans next to eachother you double the volumetric air flow but the static pressure is the same. BUT, if you place 2 fans ontop of eachother you double the static pressure but the volumetric airflow stays the same. so for each layer of fans you add you should see a linear increase in static pressure. Also a suggestion for a future test: you have looked at direct contact peltier cooling but i think there may be a test which could produce potentially favourable results. Thermoelectric coolers in industry specialise in cooling a closed system with no intake or exhaust. if you took out the intake and exhaust of a PC case and installed a thermoelectric cooler so there is air circulation inside the case but no air leaks. the cooler acts as a heatpump removing energy. With one of these coolers with you could expect ambient temperatures within the case to be sub zero. This is how they are used in industrial cooling applications including IP rated electronic cabinets. I don't know if links work in youtube comments but google DBK coolers, we have an office in USA. www.dbk-group.co.uk/peltier-cooler Keep up the good work! these are my favourite types of videos!

[@0xGK]

I can tell Linus is so much happier with the recent changes to LTT. Big props to you Linus, its great to see you really happy.

[@minklmank]

Reminds me of how we used to stretch pvc water tubes over weirdly sized glass fittings back in my university research lab - just put the end of the tube in a small beaker of toluene for like ten seconds and then you have about half a minute to get it onto your fitting before it somewhat hardens.

Great more of my favorite content, sketchy cooling solutions. Kyle is great BTW keep including him in these videos.

[@SebP85]

Car Guy Here... A cars heater core ISNT at the front of the vehicle. Its under the dash, inside the cabin. It has two coolant hoses that run FROM the engine, through the firewall, into the cabin where the heater core is located. It recirculates hot engine coolant to heat up the core.. it uses your cabin air blower (same blower the AC uses) to blow that hot air through the vents. BAM. Automotive Heater.

Shout-out to shroud 🤣🤣00:11

[@Stealth86651]

Use outdoor pond pumps, they're meant for long lines and head pressure. Those indoor pumps are cheaply made, you cannot replace the impeller (which most outdoor ones can), and fail quite a lot if they're under some load. They're just not meant for that. Ends up making the price be a bit deceiving, as you'd be replacing the indoor pump every couple months or so which would put your budget pretty unreasonable. Not to mention if viewers tried that and had a failure resulting in damage, the outdoor pond pumps are just a MUCH better option. It's one huge issue with a lot of these videos, it's a great option if you're planning to run something for a few weeks, but many of them fail to take into account longevity and failures which are pretty likely in a few months or so with certain setups I've seen.

[@DracolegacyOfficial]

The next experiment needs to be with a tiny water to water heat exchanger connected to the faucet.

[@Tubatasm]

I think they've done that before!

[@JackieBright]

​@@Tubatasmif I'm remembering right, they just plumbed the tap straight into the cpu block and put the outlet down the drain

[@Sartek]

I built one of these back in the early 2000s using the heater core from a Suzuki car. My temps stayed rock solid no matter how much load I put on it. I used a 5 1/4 Bay reservoir. The best thing about heater cores is that they have a higher flow through the internal water channels

[@gyulamasa6512]

Oh, those nice times... I did such a thing myself that time! - If you go to a junkyard for a heater core, ask the owner/seller, and they give you a proper size one. (I could buy a brass one that was exactly 120x360mm, with 1/2" pipes) - Please use proper hose clamps! They are cheap, made of metal this will not expand even if they heat up - The aquarium pump was definitely the weakes link in this setup the impeller inside broke like every year and it did not have any RPM feedback - I had to go to a machine shop and let them make my CPU block. And yes, it was brazed. - I also made a custom reservoir from brass anf 4mm plastic tube. - That time 120mm, 3 pin fan was non existent - I made a cute wooden box for the radiator, that was sitting on top of the case - It was a reliable system. Even when the pump impellers broke, it did not completely stop cooling. Just some higher temps were the symptom. Once it ran without the pump for a week. (inspite it was cooling a 3GHz Pentium 4, which has been really hot) - Today, we have all the needed stuff available from Aliexpress, so it is not really necessary to struggle this much with such a setup. I am sure, you can even get a full custom setup for about the price of that AIO, that you only have to assemble, and no craftmanship is needed at all.

Fantastic demonstration of how motors and fans are just generators that you feed power *into* instead of *out* of. The (seemingly unplugged) LED fans spun up hard enough to generate electricity and power the LEDs.

[@ZachDxn]

Honestly getting a cheap or used AIO isn't the worst option. I bought the first gen Corsair H100 for my 4770k waaaay back when AIOs were still kinda new. Ran that thing for about 3 years stock until it stopped cooling as well then just cut the tubing and added a DDC with the same rad, replaced the fluid and just unplugged the pump in the cpu block. Worked great for years. Ran that on my 6700k for years as well. I've since upgraded to a fully custom loop. But it worked great. At the end of the day, anything works assuming you have good seals and a quality coolant with biocides and anti corrosion agents.

[@Marcos-FTO]

Please note that these kind of pumps usually require the coolant temperature entering the pump to be below 35 celsius / 95 farenheit. Specially when used in-line (not submerged in water). Great video !

[@rydekk-4644]

Did you auction this too?

[@joseislanio8910]

[@TheMostUt]

So, as it turns out, this is nearly exactly what I did for my water cooling. I do have PC parts, 240mm rad, 50 dollar PC water pump. The rest is constant pressure automotive clamps, silicone tubing, eBay water block, semi-custom mounting bracket. i think I spent 200 after all was said and done, and the system handles approx 250Wish of CPU heat. FX-8350 oc'd to 4.8GHz @ 1.365v. CPU will hit 0C thermal margin with 96F water temps while encoding video on CPU alone. Setup includes Nidec VA450DC x7, including one with a shroud pointed directly at VRM. Of course the Thermaltake Core X9 makes fitment infinitely easier. The biggest thermal limitation on my current setup is the CPU HS to water block interface. Also running distilled water with silver coil and a couple drops of dawn soap.

[@tyrannicpuppy]

Linus: Camera time is expensive. Also Linus when he even gets near Alex: I can make this work the super jank way, what you talking about. Everyone watch this... As much as I adore watching the chaos in action, I am firmly with Kyle on this though. Sure, that AIO is expensive. But it just works. I don't want to have to lose my sanity trying to jank up a more effective custom solution. Even with professionally made parts that fit together properly. The AIO's true value is peace of mind and ease of installation and use. And IMO is worth every extra cent because of it.

[@skharppi]

In Finland we used to use radiators from mopeds, not heater cores. They don't need as much static pressure, they're made for cooling, they have smaller fittings and they were cheaper.
