My rack-mounted gaming computers are putting out major HEAT into my mechanical room and I only have one way to cool this mess: water cooling the whole room using a PT Cruiser radiator in my backyard. It's not as stupid as it sounds!

Linus's insurance company has to be so grateful for all of his documentation of things that aren't covered
this DEFINITELY WINS the internet this week!
Linus' insurance company is LTT. If everything fails dramatically, he just has to bring the camera crew and make a few videos out of it. It pays for itself!
High brow humor, stuff like this is rare nowadays (online)
since their main scope is to create content, i guess this get dismounted as much as the crazy builds go back to the shelves. and no, there is nothing bad in this
Life tip: record all of your personal items, and everything in your house. If your house burns down the insurance company will likely say your house was empty when it burned
Its really hard to believe that LTT didn't have Alex for the majority of its existence. Dude can carry videos and has that same level of "jank but knowing when its not a good idea" that Linus does
I consider it to be 'Genius-level DIY' whereby it is in no way genius
hasn't he been at the team since like 2015? that's more than half of LMG's existance
When I saw the janky powersupply I died
He's like Linus if he'd finished an engineering degree
The dude can't even put PTFE tape on the right way, he aint that good lol.
I cannot tell you guys how much I have missed these janky-styled videos of yours - not every single video HAS to be all professional/"produced". We need MOAR of this!!
Agreed. It seems like the videos have become more and more produced. And I don’t know what to feel about it
@@rabusse Even this was very heavily produced. Nothing like the old water cooling video.
I love how just introducing Alex is enough to let people know that this is gonna be a masterful janky build. Nobody can predict just how janky it's gonna get, but somehow you also can trust that it's gonna work too.
The best way to prototype anything. Janky enough to sketch people out a bit but working just well enough to prove a concept or idea is feasible without spending too much time or cash.
The change from exasperation to astonishment when Alex said “I spent like $300” was comedic gold
On probably just fittings and tubing . The pump is another few hundred
I love that every time Alex is about to do some Janky stuff he's wearing a flex seal hat.
... He's always wearing a flex seal hat
So yes 🤣
Cuz flex seal is a janky but valid fix lol
Haha, totally had not noticed that.:)
They should turn an LTT backpack into a whole body water-cooling suit.
Linus: 10K on a PC is Fine
Alex: I spent Like 300$
Linus: Shut Up 😱
$9950 of that PC is parts from his sponsors/"Borrowed" from work. The $300 is cold hard cash out of Linus' pockets XD
I am continually impressed how expensive threaded plumbing fittings are.
99.99% of that money for the pc is from sponsors + linus spend a quarter of a million on framework industries

I want to see a whole house integrated server system that pumps heat into the house in winter and out of the house in summer. That works with the HVAC instead of against it.
You are describing "radiant cooling and heating" the problem is Return on Investment (ROI). Something like a Warmboard system is very solid but compared to forced air it's several decades until you see your money come back. There's another company who does the same for cooling.
I've been researching a similar idea for a while now. I thought it would be great to combine a thermal battery or geothermal with solar, then I was like why not just simplify it by running pex tubing into the floor and ceilings but it turns out to be 30k just for the fixtures, system, and engineering.
If you have a commercial use case, lots of money to burn (YT channel to write off the costs) and an understanding wife then you can buy your idea now. Otherwise your best bet is solar + battery + geothermal + variable HVAC.
@@charlesnl7 exactly ! --> make a video out of it and ROI is positive off the chards again
@@charlesnl7 Linus's house is already heated with a hydronic radiant system. All the pipes/etc are ran, and it'd actually be relatively simple to plumb the server radiator into it, with a heat exchanger from the server loop into the home heating loop, and another heat exchanger outside, and then a simple manifold/valve bank to control whether it dumps its heat into the home heating loop or outside.
@@Jutilaje thank you for the information. I didn't know he already had the system installed, maybe I might have accidentally skipped over it.
You sound like you know what you are doing but I don't think I'm that confident to do my own HVAC and plumbing. I am learning as I go so hopefully one day I can build my mom a nice house.
@@charlesnl7 He mentioned the Hydronic system in a previous video, from what I've gathered it's somewhat common in Canada.
This is definitely the best use of a PT Cruiser I’ve ever seen.
Yes, the best use for the whole car.
totally true.
I almost yoinked a turbo from one for giggles. But it turned out to be the reason the whole car was tossed...
Facts
Hey hey come on now. My mother had one about a decade ago and while it might be up there with Multipla competing in the worst looking car category it really isn't nearly the worst car to drive. Sure it had some weird grounding issues but that was an easy fix and it took a couple of months to break the transmission when it was borrowed to an older man who had never before driven a car with automatic transmission and kept yanking the shifter in all the wrong ways while driving (most cars in Finland still to this day have manual transmissions).
I liked my PT Cruiser. Characterful, good looks, nice to drive, useful rear space. Electrics were unreliable and the 2.4 petrol guzzled fuel. The original 2.0 wasn't good. The 2.2 Mercedes diesel was better. I let it go for something more reliable and fuel efficient, but much less interesting...
alex being both the voice of reason and the voice of chaos and linus just dying. this is why i watch ltt

More like 'the voice of gimme your wallet Linus'... I swear, 80% of LMG's expenses are JUST Alex projects xD
@@ianvisser7899 as it should be xD
If the heat generation in the mechanical room is relatively constant all year you could replace your water heater with a heat pump water heater to move the heat from the air into the water for your house for showering and cooking etc. Would cool the room down a fair bit, residential models can typically pull about 4,000 BTU/h out of the air. Cost more than what you did here (~$3,000 CAD) and definitely not as fun but would likely offer real savings if you're heating water with natural gas currently. Fun video!
I have one. It's great. However once it reaches the set temp it doesn't kick on until temperature drops low enough or someone takes a shower. Not sure if it would be enough to keep the room cool but it does take a few degrees off my hot garage temp. Best part is dehumidification too, but then you need a condensate line.
I was thinking about home heating the whole time too
Lower mainland he could probably get away with a heat pump but the winters can get bad down there as well and if it gets to -20 he would be pretty much hooped with a heat pump
@@69clamhunter69 most residential heat pump water heaters sit inside the house so it's taking heat from there as opposed to sitting outside and taking whatever heat it can find in the outdoor air
@stephen mcewen i havent seen an indoor heat pump the ones i have seen and installed are built onto the compressor that doubles as our ac compressor they have been outdoor units and given linus lives in the same province im pretty sure the one he has is similar not saying that you are wrong or nothing just saying that the unit i am guessing he has doesnt work well in colder weather canada has been pushing heat pumps on the folks up north in minus 20-40 weather as opposed to a natural gas furnace even taxing heavily on gas appliances but the thing is their heat pumps they are trying to push dont cut it in the cold weather we see up here
the way linus said SHUT UP when alex said it cost 300 dollars is to silly
it was epic, i replayed it so many times lol
Just some notes that came to mind, I'm a nuclear engineer and do some work with heat transfer. One, in the future you're going to want to mount your heat exchangers horizontally versus vertically where possible. It makes bleeding more of a hassle but will reduce the pumping power required to drive water flow while also allowing you to take advantage of convection on the air side. Two, as others have mentioned, you'll want to make some ducting on the air sides to help guide the flow and leverage things like the stack effect. Three, consider taking advantage of simulation tools to help you properly size the system. It would be relatively easy for your engineering team to use Modelica and many available free libraries for HVAC and thermal transfer to create models of your cooling system. It's completely free and very easy for engineers with any level of programming experience to utilize. Companies like Meta use it for modeling their data center cooling and this would be really cool to see. You could easily simulate your current and future mech room heat sources to determine the sizes of heat exchangers and everything to properly size the cooling equipment. And you could examine different configurations of things like pure air cooling, leveraging the pool as a heat sink, different heat exchanger types, etc. Hell, you could even design the system to be partially or purely passive for extra redundancy and to reduce the house load on your solar panels.
It's strange running into a nuke in the wild! What kind of work do you do normally, if you don't mind me asking
And I work with HPC and well the heat exchanger on the back of the rack *has* to be vertical. Thing about it for a minute. Got lots of rear door cooled racks at work. However if he plans on water cooling his rack long term then he will need an appropriate rear door for the rack. They are unfortunately not cheap like over $10k each.
This guy cools
You always know when someone didn't make it to the end of the video
i've always wanted to see a computer cooled by NaK, i'm a chemist, you a nuclear engineer, commenting under a big youtube channel. what could go wrong
Alex' jank adventures are honestly my favourite part of LTT as a whole in terms of entertainment value.
Nothing's as permanent as a temporary solution that works.
the zip ties just flying into shot at 8:00 are chef's kiss
The Flex Seal hat is just the best thing to wear to a video like this. Also, could you use the PC heat to heat your house more and reduce your power/gas bill?
YT is already taking care of the bills 😜😂😂
since its the basement just blow up the radiator for free underfloor heating
No he is going to dump the heat into the pool, problem being that there is no pool right now
Mechanic here. Since this proof-of-concept worked so well, there are a couple of ways you could easily optimize it, if you're willing to spend a bit more money. Many aftermarket racing radiators are solid, welded aluminum, and most of the radiators for muscle-car era vehicles use a wide design. On top of that, many of them have the option of coming pre-fitted with threaded hose adapters welded directly onto the tanks. Couple that with some 12v shrouded radiator fans that are designed to fit them directly and maximize airflow, and you could have a full server rack heat transfer system right out of the box, minus the tubing.
This is something worth looking into it if the original plans to use the pool are not going to work those aftermarket radiators + fans are no joke they exchange a lot of heat quickly they should be able to handle that server rack with maybe 2 of them, idk what would be the equivalence of watts those radiators are rated for
An aftermarket radiator or two would take this project from jank to a real cooling solution. I think real radiator fans would do wonders too I'm not an expert but I think that many small fans is not very efficient. I also wonder if LTT could get custom radiators built to size and spec
I'm just asking this here because an individual comment probably won't be seen by anyone, but isn't there a risk of the water freezing in the winter? I have to imagine the reason why it wouldn't is due to the water being heated from the server, but if it drops to -30 outside would that be able to drop the water temperature enough to potentially freeze? Not sure how cold it gets in Vancouver, I don't think as cold due to the ocean keeping temps more constant, but where I am in Canada it can definitely drop that low in Winter.
Would love to hear if anyone has an explanation on this :)
Or just get a MO-RA3 420x420 rad. Or a Alphacool NexXxoS XT45 1260 SuperNova full copper. Those guys could actually work as car radiators... well, definitely sub-optimally in terms of peak flow rate, but surface area - yeah boi.
@@patricklloyd1797 well since the water is never in contact with the PC parts this would be like a constantly on coolant system on a car plus with the antifreeze that can be added to it still I'm not from a cold place so idk anything more to this neither do I have experience in custom cooling solutions on cars
my favorite thing about this channel is that no matter how big you've gotten you've never stopped just bs'ing your way through potentially catastrophic projects. Please never change.
I love how so many of LTT videos are just coming up with some janky solutions to solve self inflicted problems.
No one has a setup quite like Linus’s
it prints money!
I think Linus is addicted to watercooling at this point
I mean who isnt? Its basically how your body gets rid of heat aswell, which means it works. why fix what aint broke
He probably has some quick disconnects hidden in his trunk somewhere.
he basically tried this a decade ago in the old office and it was horrible
"I can stop any time I want, I swear!"
Thermodynamics really is compelling enough to be it's own video farm. And Linus knows it.
that "shut up!" that Linus released over the $300 connerctor was so genuine, i really had to laugh out loud. poor Linus :D^^
A few thoughts, you can obtain semi ridgid blue and red water pipes that can be "plumbed in" permanently and look quite good. Get rid of the outside radiator, and use another underground loop of water, it doesn't actually need the pool for heat transfer to work, heck a single run loop of about 2 lines laid with a ditch witch, and the under the frost line, which i likely shallow in ca, will stay the same temp year round so you can model transfer load. temp sensors for water in and out, some out in the loop and a Arduino + program can likely optimize motor speeds. Put radiators and sealing panels on back door, sealing panels for front area, sealing boards don't have to be complicated though, signboard is corrugated plastic and can take a screws and bends pretty well. Love the plan, would do something similar myself if i had the house for it.
Exactly! It's just a geothermal system with a ground loop
They should really just get a three way valve and an extra heat exchanger. They could tie the server heat into the radiant heater system manifold (that they pointed at while talking about the pump) in the winter, and then switch the valve to pump it to the pool in the summer
I love the fact that Linus has managed to make renovating his house into a job for his employees and monetize it. Truly the wonders of the 21st century.
he does this to get the buissness expence tax write off
@@JudgmentalFranklin i think it's both, but kinda favor the content think, because this company likes their work mostly and each other which should make those videos fun
1 thing is clear. The price of electricity in America is apparently very low.
@@henkholdingastate $.10/kWh where I am, so yes it's pretty cheap. No idea how that converts where you are.
@@arg8763 $0.10 per KWh.....wow. At that price I wouldn't worry about anything.The normal price in the Netherlands was 23 euro cents per kWh for the common people, but now with the energy crisis, consumption up to 2800 kWh is a subsidized 0.44 per kWh (per 1-1-2023) and if you go over that, it is just over 90 euro cents per kilowatt hours. What a drama. But nice for the Americans who pay so very little for energy (including the very cheap gasoline price) Greetings from the Netherlands

You could use a bathroom fan to exhaust the hot air
This video hit my sweet spot! My profession was previously L2L Heat Exchanger Design and is now Data Center Cooling Pipe Design! The little brazed plate job from alpha laval would have been fine with process/pool water and PG/EG solution. They make versions out of nickel which would probably do the trick. I would personally probably go with one of the readily available shell/tube designs that they commonly use for pool heat (ej bowman makes some). So far as driving air for hot/cold isle we don't really use box fans, or any style of axial fan. They don't perform well with higher static load (ie. blowing or pulling through a coil), instead we use centrifugal or radial fans, which allow us to overcome 2-4"wg of static and still make the airflow we need. As a side note, they do make a fairly affordable NPT to Barb transition in PVC and/or Nylon (Ooof, that's a lot of brass, lol).
I want a WAN show segment discussing how linus finds insurance for his house after shenanigans like this lol
simple, don't tell them ;)
They just wouldn't insure a flood caused by this.
But the reality is when you have enough money, you can have personal insurance funds that are just your own money and not go through an insurance company.
I want Linus to simulate air conditioner failure on the hottest days of Canadian summer so we can find out exactly how hot this server room will get. I predict it won't even be habitable by humans.
the "janky cooling" and "linu's new house" series colliding is great
It's linus' not linu's

Actually cool to see that this worked half decently. I plan to do something similar. My server room is setup with a hot/cold aisle like in a DC so my plan is to setup a radiator somewhere in the ceiling on the hot aisle and then suck air through it and dump it back in cold aisle. It will just recirculate through servers and rad. I will then dump the heat into the garage, which I want to heat anyway. I will probably also have a furnace supply/return duct which will have dampers. They'll open as required, such as in summer when AC is running.
Soooo im a plumber... my gawd lmfao this is the most home owner special thing ive ever seen love it lol
10 years later Linus: So we are moving again but instead of moving to an existing house we are building our own.. out of Noctua fans and radiators! If your wondering how we are heating our house it's SIMPLE we put pipes form our offices to my house moving all the heat produced from all the computers and servers! Any excess goes to the pool, yes the year round steaming water will get some getting used to but the wife approved it as we basically have our own outdoor hotsprins now!
With how much time and money Linus spent on his house, I genuinely wonder why he didn't build one from scratch.
Hands down funniest thing I've read today. 🤣
he will be moving to datacenter
I used to work in the plumbing department at a hardware store, and this would 100% be a random project that we would constantly get at least 2 or 3 times a day lol. Takes me back
Dafuq? People cooling their rooms with radiators???
@@rkan2 I mean it's essentially the same thing as a heat pump, but without refrigerants being used to take advantage of state change cooling.
@@rkan2 lol. No I more or less mean that people want to hook up random things that probably shouldn’t be hooked up together, and it’s the job of the person in the plumbing department to figure out how do make it happen with a random assortment of fittings lol. So I just pictured helping alex with that issue
When Linus said "How does that work, that's like magic" it was so adorable I wanted to adopt him even though we're about the same age.
In the Summer time, you could set the radiator up as an evaporative cooler (basically draping a damp cloth over the outdoor radiator) and then you would have an efficient heat exchange... :)
Always love seeing Alex. Was a very good addition to the team.

6:0 The issue with the Grundfos circ pump you purchased is that its cast iron made for heating. It WILL rust as its cast iron that will be wet, and because the loop isn't sealed it will be getting freshly oxygenated water all the time. You need a circ pump that is rated for fresh water, for example hot water loop circulator, that is either brass/bronze or stainless, that won't put a bunch of rust into the loop and clog the radiator. 🤠👍
Or at least get the loop filled with boiler system rated antifreeze to avoid killing the pump on short order.
its "'temporary'' lol
@@muzallisam5068 yes, but that was most likely specd for the future install. that can't be a cheap pump and if it was a throwaway pump, it probably wouldn't be the same model as what was used on that pre existing high end install that likely cost a small fortune.
@@danl6634 Antifreeze would also protect the outside radiator from freezing.
I want to extend a round of applause to the editor for their hand in lending excellent comedic timing to their cuts and personal touches. 👏👏👏
Alex is my spirit animal, he's lowkey one of the handful of reasons I am studying engineering. Alex if you're seeing this, keep it up lol
Alex Uponor Pex/ Pex A.
Or put a vent output on the AC for that room on a zone gate and get a fresh air intake on zone valve for when it's winter so you don't actually have to turn on the AC. Just use cold fresh air from outside
Honestly, even just venting the room to the outside would probably solve overheating 90% of the time. I do stuff like this professionally, residential low voltage and systems integration. We put at least 1 full sized server rack in every house we do and ideally will have a mini-split air conditioner installed in our rack room but even just a fart fan works basically well enough. Plus our systems have amplifiers in them which create more heat than computers.
All in my head when I was watching this is "Get an Air Con / Heat Pump, problem solved"
Box fan in the doorway. 🤣 I was wondering when someone was going to ask if it could work to heat the rest of the house.

@@Hami10101 Wiat, THIS is the 2k that I signed for? Holding the tiniest piece of metal.
While watching this video, I realized something.
You guys (the LTT crew) are the reason why I'm so invested in tech so much.
The option of "we can't do that" is almost non-existent, and as somebody who works in tech, this was a really good influence to try either new projects, helping customers properly and come up with new ideas.
From the bottom of my heart, thank you. You were the motivation throughout the years that was leading by example, not by speech.
You could use a cooling liquid like R134a to make a real heatpump and use presure differentials to get to 'extreme cooling' . I am pretty sure you have some engineers that could make this happen.
With the 3D printer on the bench, I feel the need to point out that you can 3D print hose barbs that are very pressure tolerant - which is what I did at home. You know, like 0.30 $ worth of plastic instead of 300$ worth of fittings.
"No, the worst that can happen is my house both floods, and catches on fire at the same time"
I almost spit out my lunch with that line 🤣🤣
As the outside heat exchanger you can dig a hole over 1.5 meters deep, throw there spiraled 30 or more meters of PVC pipes, and cover it with dirt.
It should keep a stable temperature the whole year round (usually around 5C if you're deep enough). The hole needs to be quite big to spread the piping on the ground, but besides that it's pretty much the best upgrade to your cooling system.
That's surprisingly cold
@@sp00n It gets warm once you dig really deep, like hundreds of meters
@@sp00n in the army, it used to be a hack that u dig a hole, dump a ration dessert pack in it, wait a couple of hours, and u will have an decently cooled dessert.
And that is in the middle of summer
Sadly, this isn't a long term solution. over time the constant heating will warm that ground and it will stop providing cooling. Digging a hole works great short term, but not so much long term. it would work fine if you had a really large area to dump the heat in to where the ground can stabilize, but in a small area the ground just gets hot.
This.
Looks like a really fun experiment. Keep an eye out for condensation. Might be time to build yourself a mini cooling tower. Do it right and you can cool your house with it too.
Every time Linus does one of his crazy radiator experiments, I just remind myself that it's always in the name of science.

Being that its a pt cruiser radiator, its most likely a single pass "top-down" radiator. It will normally flow from inlet on the top to the outlet on the bottom.
In this...jank configuration, you have it mounted sideways in a left-right flow. Because of that, you may have an air pocket at the top (technically side) of the rad which would explain the much higher temp readings.
If you reorient it with inlet at top and outlet at bottom, it should balance out much more. If it does have an air pocket, you might be able to bleed any air out as well (if you haven't done so already) by just holding the rad with the outlet vertical while pumping.
That being said, even if it doesn't have an air pocket, the flow across the radiator at the top (again, technically side) may be hindered because of orientation and you are getting a pocket of slow or non-moving water that builds up heat.
If that doesn't fully work, you could reverse the flow to feed from the bottom up (still orienting it with inlet/outlet at top/bottom vs side/side).
Another thing to implement in the system is a water detection via raspberry pi or arduino and have an alarm and shutoff in place. If it leaks and gets detected, it can warn you and/or drain the loop thru the floor drain. I'm sure Alex could rig up an Ortho water control valve to act as an emergency open valve. And would make for an interesting video as well.
12:02 there’s no windows - except the one running on the computers eyyyyyyyyy got em!
I would recommend a combination of a stand-alone heat pump for water heaters (I thought I saw a water heater) and a mini split unit for the room. Run the mini split at 70f, and the water heater will pull it down further.
I was thinking this exact same thing. That room is *perfect* for a heat pump / mini-split.
Trying to do this with water isn't a very good idea. Why? Because when something goes wrong with water it can destroy your entire house in an instant. Nothing bad will happen with a heat pump / mini-split except the room will get really hot again which a thermostat with an alarm should take care of. Shouldn't be a problem to get it installed in there after the fact with a mini split.
I know they aren't saying this is the best way to do this and they poke fun at their idea throughout it. I just appreciated your comment on a more sane solution as I didn't hear them at any point in the video say "hey, if you're setting up hot equipment in basically a closet like this, that is where you would use a mini split / heat pump normally". All the facilities I worked on that had server rooms / closets had these.
You've done this before back in the day. Good to see an update on it.
Linus experiencing what it's like to live in the tropics and solving it with water cooling really is something I wasn't expecting to see
I was just thinking that these temperatures are kind of a normal day in my country. Then I remembered that for these guys it’s probably torture 😂
@@prospersikhwari5289 They're Canadians, so they melt easily.
So is my car
@@prospersikhwari5289 Also a huge difference maker is how wet/dry the air is, both on the warm and cold side of things. From where live in Norway (south-eastern part), I've had people living all the way up north saying it was colder down here than up there even if the difference in temperature was at least by -10 degrees celcius. This is due to the air being more humid/wet compared to the dry air up north.
@@prospersikhwari5289 But they're Canadians from BC, they don't know what either true cold or true heat is...
Probably repeating what others may say: do not pump the water end to end. Keep the pool side and the rack side in separate loops and use a liquid to liquid heat exchanger between the two. That way you don't have contamination issues, and can drain and maintain each loop separately.
The pipework is buried in the screed of the swimming pool much like underfloor heating so water contamination should not be an issue
@@Saaj2 Having dealt with chilled water systems, contamination is part of the deal. Also, the anti-corrosion and other chemicals you need to feed in is nasty stuff.
@@TheOtherNEO Of course, corrosion inhibitor and biocide is a given, I thought you were talking about contamination re. pool water and cooling water mixing
I think they should just open the door as Alex suggested at 0:45 . Allow the heat to flow into the house. In Canada in the winter that seems like a good option. Maybe install a vent in the door.
You guys are literally mad geniuses.
Alex is the king of knowing a ton about technical stuff but having 0 fear of coming up with the most jank duct-taped together solution for any problem that should usually require expensive specialized equipment.
As a Journeyman plumber, it is always funny watching Linus struggle with running water lines.
As a refrigeration tech this video shortened my life more than the phosgene I've inhaled previously.
As the President of the United States I love ice cream
Ik he was amazed by them shark bites 😂
I absolutely adore the chemistry the staff has with each other. I think my favorite is a tie between the bromance of Linus and Jake and this "We don't have a plan B" vibe with Linus and Alex. I laugh every time at these videos. Have a great holiday!
the first two frames of this video is fantastic
whoever did the hvacr load calculations for this house and designed the system should of used a heat recovery chiller you could then use a water source fain coil unit to cool this room.
Linus' house is being held together by zip ties, improper fittings, and flex tape... I'm without words
Small hint. DONT use duck tape on ducts, it's one of the few things that sort of cloth backed tape is bad for. You need the foil stuff designed for ductwork.
Aluminium tape, metal tape
Well done, I was looking for this comment. First Prize to you🏆
why is it called duct tape then :(
@@lovely-shrubbery8578 It isn't. Duck tape, not duct tape.
@@MarianKeller No it's not lmao "duck tape" is a brand name that came around long after duct tape lol
This makes me wonder if you already knew you would plant a big server somewhere in your basement of your new house (whether this house was already existent or newly build) was it not just more easier to create a wind flow within that basement? A while ago there was a video about the 'daddy' of all fans, but still I believe there could be even bigger fans that could be used to create a constant airflow through your basement and in a perfect world the main server straight in the middle of it.
9:30 Me a plumber being humbled by Linus realising the little things that make my job cool. He has the life bro
I was recently watching some old LTT watercooling videos, and there were a lot of comments jokingly saying he would eventually water cool his house...
Yet here we are
It’s been a while since we got a home upgrade video. And hey, the (temporary solution for) home water-cooling is finally happening. Although it’s unfortunate that the pool isn’t done yet, throwing a wrench in everything.
I made an "air conditioner" (cooler really) for a small room that I used as my hidey-hole when involved with a programming project, etc... It was set up much in the same way as your "niffty" setup, except I used ice cubes in the water and it performed fairly well. Draw back was the draining the excess water and restocking my ice cubes. Never had a leaking of water which made me a happy and cooler person lol.
Every Video with Alex is s+ tier
I’d just love to see Alex show up to a random house with a bucket with a hole in the side and see how that goes.
I felt the freaking dad rage Linus got at 4:10 on the egregious cash used for that whole contraption.
Related.
I love watching computer tech people come up with blue collar solutions, good job guys.
I love the fan idea at the end.
can we all appreciate how far Alex has come in engineering something. like legit this is a much better design than alex would have made when he became the defacto engineer for linus.
Seeing Alex and Linus together never gets old. Great chemistry
The chemistry reminds me of Phineas and Ferb.
The jank but works kings fr
As someone that has does plumbing electrical and machining professionally, it actually hurts to watch sometimes and I'll need to take a break
"...I wanna be buried in LTT Store clothes." Yes, and don't forget that it would make a fine video too. 😂
4:40 I made a similar solution a few years back to my AC unit at home, its outside unit fan motor blew when it was +35C outside and the delivery time for a new motor was 3-4 weeks. I did not want to sleep in the hot bedroom without AC, so I had to come up with a solution quick. I had almost 200 120mm server fans in stock and I used some of them to make a 'fan panel' that I could place inside the outdoor unit to cool the radiator, in place of the big fan and its motor. With an adjustable PSU I got the speed to such that they didn't scream and annoy the neighbors. The idea worked perfectly and the AC worked nicely until the new motor came in. The AC unit had also internal monitoring for the fan motor, it needed to get pulses from it and stopped working if no pulses were detected, or the motor was not connected. I had some small DC motors from another project and 3D printed an attachment and a holder for the broken down motor, so that the small motor could slowly turn it to generate the pulses. It was hot as hell, I had no time or interest to make it any nicer. I noticed that the AC controller did not care about how fast the pulses came in, as long as timeout did not occur. All of this worked and I got the AC running and didn't have to sleep in a hot room for more than one night.
excellent editing cuts on this one. props
Yes a Thanksgiving miracle!
Questionable engineering with Alex!
My favorite!
Hybrid hot water heater. I did the exact same thing in my house but I put a Rheem heat pump hybrid water heater in my server room. That converted the hot air from my server rack into hot water for the house. Every time you take a shower or wash dishes, you're cooling the server room. Only uses 200 watts.
Alex the jank king videos are always my favourite, please do more.
me an hvac service tech seeing the boiler set up and just drooling. wish all installs were that beautiful
5:10 *laughing in Australian*
Asian laughing menacingly
Australian here, you often have to spray the ground with water just to walk on it during summer lmao
Is Alex's official Title "Senior Janky assembly engineer"? He seems to get caught up in all these things. Good stuff.
Funny the terms people use. In Australia we would call it 'Bodge Job' or a 'MacGyver'
Lolol the "And Alex" add on was great. Love the DIY "jank" its epic. Especially coming to a tech channel to see two guys do plumbing :)
Yay finally a house video. More of these please
As an HVAC engineer these videos are just the best and so fun to watch :)
Is this along the lines of all the things you wished you could try with your profession, or an enumeration of exactly why you don’t do these things as part of your profession?
@@TAP7a I'd assume both lol
Even funnier when your a HVAC tech building and working on the exact systems they are attempting to copy
The utilization of waste heat (particularly in data centers) is a very interesting up-and-coming topic in research, I love that Linus' house has become like a microcosm for engineering and cooling technology and the idea of heating the pool (at least partially) with waste heat is excellent.
I can’t wait for the vid once the pool is finished.
The underground pipes may be a blessing in disguise. It should help cool the water a bit coming from the pool, but I doubt it will make much more than a few degrees difference when your system is at pressure. Really interested to see how you put all the pieces together, at least the proof of concept is there. :)
Here is a crazy idea....
Use a heat pump to CAPTURE and UTILIZE the heat to make your house warmer in the winter, then in the summer, you can use it to either pre-heat your hot water using a liquid-liquid heat exchanger or as you mentioned use it to heat your pool. By adding a heat pump to the mix it will maximize the benefit. You can use cold/hot water via insulated pipes to keep the compressor outside or anywhere the noise won't be a problem. Mr. Cool (and others) make DIY mini split heat pumps to help you maximise energy utilization and keep the NAS/PCs nice and chilly year round. Obviously some of the heat flow will change during different temperatures.
Good Luck! (BTW PFideo is an alternate German spelling for Video ;) )
As a German - no it is most certainly not an alternate spelling.
+1 to this. A heat pump water heater will/wouldve happily taken the heat in that room and used it to make your hot water. I think I've heard of commercial style heat pumps to move heat within buildings, but the water heater could've been an easy win.
I’m also Team heat pump! The pump takes the energy out of hot air and releasing cool air to the room. The heat could other go to the pool or the house. Also head pumps are crazy efficient!
Condensation should be accounted for.
a heat pump would be the most efficient way to move heat in the first place as you do not need much difference in temp for it to work
-difference in air temp
One of the cool things about those shark bite fittings is you can push fit copper, cpvc, or pex water lines in one fitting. If you had just used the two sharkbite 90s, and a roll of 3/4" pex tubing, many fittings could have been eliminated.
And remove bucket. It should of just been closed loop.
@@guyod1 im guessing they had the bucket to provide a bit of pressure and allow air to escape, otherwise they would have had to bleed the system. also it would fill any small leaks. also @kevin much prefer the hep2o fittings, work just as well and cheaper
I love Alex's water cooling videos
Ohh Man...the best fix to the problem 🙌
