The only benefit of watercooling is having bigger radiators (more than 360mm) and more clearance on the mobo, otherwise the risks of leaks and defect products are not worth it. If you want performances, low prices and low noise levels, go to noctua. Pumps and watercooling fans are louder, and overall more expensive.

a suggestion from a mechanic... instead of just filling the rad when we work on cars, we use a fill cup or some call it burping the radiator. so you use a funnel that fits tightly in the fill spout and over fill the funnel, when air comes out its automatically replaced with more water and it wont make such a huge mess like that.

[@angerskarin9222]

[@JoeStuffzAlt]

For something that size, I wonder if it could cool multiple PCs. That would be a good use case. Instead of having 3 giant PC towers, you have the huge-ass radiator and 3 small form-factor PCs. I think they did a desk where the fans were on the desk, and that was a good example.

[@Nordern]

I have a tip for filling hard to fill things like that radiator, a ptreol hand pump for a outboard motor works great to push liquid through with the system off!

[@BrianHamilton01]

A trick to fill impossible loops is put a T and a valve in, then pull a vacuum on the coolant system, close the valve, put a tube in your liquid and connect it to the closed valve, then open and watch the water shoot through the entire system. Works every time on my last four builds.

[@MrSn3akr]

[@Tome_Wyrm]

Or do the same thing they did with one of the chillers. Just have a pressurized fill source. Which technically is what you're doing with a vacuum on the exit port.

[@RaccoonHenry]

this seems like something that you guys could overhaul into something amazing, a followup would be great

[@Hcwageek]

As a note - you're using too much pressure when you tested the external radiator setup on its own. 0.3 bar is the recommended maximum for a complete loop, or anything involving a distribution plate. There's a chance to damage it running pressure that high. EK notes this in the manual.

[@Praetor353]

Pro tip: use a Mityvac MV6400 automotive pressure bleeder with the MV588 transmission adapter for complex loops. It threads into G1/4 and you can power bleed any loop no matter how complex. Put 2 valves at the end of the loop to block flow and open a drain and you can perform coolant changes in record time WITHOUT losing prime. Bonus is its 1 gallon so you can mix your distilled water and coolant concentrate right inside it. I have 4 radiators and 2 pumps in a o11 XL and needed a solution for maintenance, and this is what I found works best!

[@spankeyfish]

Even the little funnels you can get with a G1/4 fitting on them would've improved this, lol

[@Kowalskithegreat]

Or just buy a Aquacomputer Leakshield, I fill my system thru the EK drain fitting on my GPU block with it's internal vacuum pump and use the auto deaeration cycle a couple times afterwards, shit's cash. vac pump sensors valves and a display all built into the reservoir cap, and the matching D5 NeXt pump has it's own water temp sensor, pump controller, display and fan controller so you just flash the desired fan curves into it once thru software and it does it's own thing with fan/pump speeds. Can even display system info like cpu temps etc on either display. caveat- pump only has 1 fan output so you can only daisy-chain 3-4 or just get a splitty9 to control more like i did

Exactly. A cheap brake bleeder and a tank full of water would have prevented them most certainly damaging the pump from running it dry.

For empty rads (or a crappy design), I thought it was common knowledge to just attach a tube to the fill port and lightly blow through it to get the water moving. It also lets you put in a few inches, or even feet, of water at a time and it can't burp on you. I've actually used a 6-12" tube with a fill cap plug on it on my last 2 builds and it tucks nicely behind front panel on many cases(above front mount fans or rad).

It would be nice to see a follow up to this video where you build your own stand alone water cooler that would be something that the average person could build or buy.

[@sithus1966]

Maybe something that uses a small computer case as the chassie and other off the shelf components. Bet they could for under $690

[@criznittle968]

It's about time we get a full tower case that triples as a radiator, reservoir and pump. It would have everything you need for water cooling, but it's also a fully functional case! I'm not talking about a case with all the liquid cooling essentials included inside of it, what i mean is to use each part as a piece of the case. Radiators with included fans for the side panels and top, reservoir front and/or back, and a replaceable pump somewhere easily accessible. Why doesn't this already exist?

[@Chloe_Priceless]

That’s why I have a MORA next to my NCase M1 :) silent pc with easy quick release fittings and a „small“ radiator on the bottom of the case for lan usage … where only older games are running and don’t need much performance

[@rubiconnn]

Is all of the added bulk and complexity worth it? I figure I would just go with a good air cooler and be done with it.

[@ConquerorDash]

@@rubiconnn water cooling is rarely "worth it". I use it because I can have powerful components and never worry about the noise. And also because it is cool.

[@Chloe_Priceless]

@@rubiconnn i done it because i wanted a relative small case which is "easy" Transportable to take it every year to the lan during the winter holidays with my friends. And for Gaming at home the NCase M1 is standing on my desk silently. I Have a 3080Ti in It and a Ryze 3700X (time for a Upgrade). At Lan the noise is forgettable. I Dont Like Big Cases but love Silence - i dont use Headphones (only on lans) .. at home i have good speakers.

[@rubiconnn]

@@Chloe_Priceless I have a Ryzen 3800x and an RTX 2080 jammed into a tiny Silverstone SB13 case and a tiny Noctua nhl9i CPU cooler and it's more than adaquate for my 3800x running overclocked. I sewed a leather carrying handle for it and take it like everywhere I go lol.

[@IcyNova115]

I'd love to see a follow-up video to this one where you guys build your own better version of it lol

[@danieleckert4027]

Put a funnel at the top that way it has room to bubble without going everywhere, this is about as poorly designed as a lot of car coolant system designs that’s why they make funnel fill adapter kits that lock into the radiator or reservoir fill and give a large area to bleed it

[@longshot789]

I made my own loop just for my GPU out of bykski stuff, and I'm finding it surprisingly excellent.

[@TheEchelon]

@@abowden5079 Nah I'm sure the individual components are fine. It's just the integration into a finished product is crap.

[@Emetsys]

Yeah I guess if you connect the fan controller to the motherboard then you are good.

[@barsei1511]

tell this bykski, you should get a job and fix that 690$ mess.

[@jtnachos16]

Not particularly unusual for a company to make the BEST individual parts, only to completely crap the bed when it comes to making a self-contained product out of those individual parts they excel at.

[@SaltRockStacker]

If you are going with an external radiator like that, you might as well just janky-rig an aquarium chiller. I have not tried it myself, but I would imagine you might have some condensation problems in the PC if the temperature in the chiller is set too low. EDIT: It looks like you guys already did one :) kzbin.info/www/bejne/fn7Xp3iYeZeAh9E

[@icarus-wings]

Where can I bid on this item?

[@nashaeshire6534]

You were lucky you didn't destroy the pump. Process: 1/ use a bucket and place it 50cm above the radiator. 2/ Then a second 10-20cm below the radiator. 3/ Open the top valve and let the water flow. 4/ Once the water comes out in the bottom bucket, close the bottom pipe. 5/ Turn the radiator up side down to expel the air. => no risk of electrocution or destruction of the pump.

[@alpacabloom1545]

They were the only company I could find offering 6900XT SE waterblocks for Sapphire, and its been flawless. It hurt watching this. Like, paranoid hurt. I'm staring at my case right now.

[@jonathanphilosof6578]

good old linus and alex crazy shenanigans with water cooling, loving this energy

[@outbackshaqYT]

5:00 that line going down and back up would create a syphon effect, making for an easier time filling and less work for the pumps, assuming I understand correctly. It should help prevent stray air bubbles too, if filled with patience :P

[@c2thew]

You guys are churning out quality content. Keep up the pace. $700 is wayyy too much for this. A car radiator hooked up to an impeller and tubes would probably be 100x better

[@Daepilin]

Watercool has a Radiator this size for 250 or so. Add Fans and pumps and you're still cheaper...

[@DrazekIronwing]

I would actually like to see Linus and Alex make a better external watercooling rad. Because i absolutely think they'll do a good job of it.

[@lambyi]

They have, it was just called the all radiators desk lol

[@somethingbrite8484]

I've picked up quite a lot of "budget watercooling stuff" off of Ali-Express, including Bykski and my experience of it all has been pretty good.

[@ryancrowell441]

Ngl these videos are way more entertaining than actually informative tech vids

[@Gobeman]

Was kind of expecting to see a MORA on display. But this is a fine video on a showcase of external watercooling that isn't Linus' own swimming pool

[@LRM12o8]

The idea is kinda cool. You could have an absolutely inaudibly silent system by just moving all the cooling to another room! 😃 ...well, at least it would be silent until you hit your modern high-end GPU with a gaming/production workload and the coils start singing the songs of their people 😂

[@Mystical_Zeus]

8:01 I absolutely love the fact they were allowed to randomly decorate the pc with straight up random shit, sometimes these things need to happen, you have to take the small victories in life but this one feels just a little bigger than that.

Looks a lot like a Watercool MO-RA3. I've been using one of those for years and it's great. It uses 4 noctua 200mm NF-A20s and I can't hear it no matter the load but it stays cool nonetheless. Edit: lol that price, yeah get a mor-ra3 made in Germany for 200 euros and add your own noctua fans and a good reservoir and D5 pump.

[@cl4ster17]

It's closer to an Alphacool SuperNova than a Watercool MO-RA. The former uses flat tubes like most radiators while the latter uses round tubes.

[@olivergottkehaskamp3369]

Same here! Feeding 500 watts into gpu+cpu when running at full blast has never been more quiet - as in, literally the same noise level as when idling. I'll never go back to a noisy air cooled solution.

[@TheZRasmus]

Got the same setup, except for 9 Arctic p14! Love the combination of a MO-RA3 and a small case.

[@2afk]

I own a Zalman Reserator

[@Nothinglastsforever]

@GH0STST4RSCR34M MO-RA pre-dates that significantly.

[@EthyrielY]

I have a MO-RA from Watercool, and it’s a great external rad. It wasn’t cheap, but the quality was great. I have it connected to a Meshlicious, and I one day want to hook it up to something even smaller. The PC may grow outdated, but a radiator is a radiator. I plan to re-use it for builds to come.

[@TheZRasmus]

I have the exact same setup! And I also keep looking for a smaller cases.. but if the cards keep growing it’s gonna be difficult 😅

[@brrebrresen1367]

have the Phobya Nova 1080 because the price on the older MO-RA units back in the day where even more ridiculous than they are today, and even the Phobya is absurd in terms of cooling. have 4x Silverstone 180mm fans running at 450rpm and my old Dual Opteron 290+Geforce 7800GTX-512 SLI build never passed 60*C. even managed to get waterblocks for the Tyan motherboard keeping that hot potato of an nforce chipset chilled. not having the heart to take it out of that build, also the "pentium pro"-era NEC server case that is modded to have that rad at the side will turn structural unstable without it x)

[@TheZRasmus]

@@brrebrresen1367 what did pay for that phobya. Maybe I am lucky, I am from Germany and since Watercool is a German company I payed 200€ (including postage) for the Mo-Ra 3 420 my 3080 never goes above 35°C even at room temps of 30

[@brrebrresen1367]

@@TheZRasmus back then 15-ish years ago the Phobya 1080 was around 80€ incl VAT here as i remember, think only the now old MO-RA2 was released (no MO-RA3) and that was 150€ and had to be imported (so shipping, taxes and whatnot...) but you also needed to buy a 30+€ grill to mount fans and it only took 120mm fans, no possibility for 180mm. think i found out that if i wanted a MO-RA instead it would have been 300+ € back then...

[@TheZRasmus]

@@brrebrresen1367 ahh, I would have decided as you did.. in fact I decided for the MoRa because it was cheaper than a LianLi 3 rads and had more cooling power

[@Ylyrra]

I'm sure I'm missing something, but why would you hook up the return line before you'd at least mostly filled it? Let the water push the air ahead of it, not try to fight past it. That said the bubbles being sucked through rather than escaping once the loop is closed is definitely a flaw in the design.

[@NinjAsylum]

Bykski has been as mainstream as EK and Bitspower on pretty much every watercooling product store for well over 5 years now lol.

[@Hans256xD]

@2:40 why would i want an ITX case on the desk and that huge external cooler next to my desk? At this point just have a bigger Case sitting next to your desk and spare the hasse and maybe even save money

The first PC i ever build myself was cooled by a thermaltake Rocket. I loved that thing so much that im still trying to find one to use in my current build. Just not gunked up and looking like its 100 years old.

[@Hellsong89]

Looks rather simple design. You should be able to reproduce clone rather easily if some parts are gone crusty. Mind you can now days 3D print and cast plastic, well as make silicone molds that was before required pretty excessive amount of money.

[@carbon_no6]

JayzTwoCents made a video about this type of cooling setup. A few years back, it wasn’t built by a 3rd party company. He took aluminum channel framing, 4 - 480mm radiators (I believe), 1 box fan and then stuck the radiators to the fan. It did really well for being homemade.

[@Veptis]

The "Did they ever try this thing?" question came up for me today... I added a feature which I never tried or tested. So of course there was a major issue with my implementation. So I had to write a PR today with some really awful explanation.
