This is the dumbest thing I've ever done... 

The passive cooling on this is crazy, maybe you can do a complete fan-less/silent PC with a bunch of radiators

You drilled a hole in a motherboard and broke it. THIS is not the dumbest thing you've ever done.

"Only a $15 box fan" ... $200 (minimum) of radiators

So just get a panel of radiators to cool my pc, got it

$16 box fan, but don't forget the $440 of radiators that it's attached to

Just looks like a typical LTT project

I think you need to apply this to either a 7950X or a 13900K with an RTX 4090 to see if it throttles.

10:08 what the doctor says when you go to your great grandpa's hospital room

why not just use a car radiator and a water pump

This is like watching a LTT video, but... it actually works... It's very odd - but I like it!

"We've come up with the most rediculous water cooling system EVER!" LTT... "Hold my beer" - Jay

6:33 jay: "how do we show airflow" phil: "dw i got you"

FINALLY! I have always wanted to see this done. I also want to see it done with an aftermarket electric car radiator fan.

I really want to see you do something like the old Linus Tech Tips "whole room water cooling" but do it the right way and show off how awesome it is when it actually works properly.

This isn't dumb, this is brilliant. I've never considered linking multiple radiators in a custom loop before, but it works great. I even have an idea for a case design that is just radiators. All of it.

“summer is a good time to travel” *muffled laugh through corona mask*

Agreed, this is quite possibly the dumbest thing you've ever done, but I digress it's also probably one of the most brilliant things you've done yet. Seriously though Jay, hear me out on this. You've created a cooling system where ultimately the only bottleneck is the water block, or even the thermal medium behind the IHS itself, so it can therefore be used to test waterblocks, thermal compound, or to prove that Intel chips really do run much hotter than AMD with incredible accuracy! and it will be working passively for 2 reasons. 1: you've got a massive amount of surface area in the fans, and 2: you've got a very large displacement of coolant to absorb that heat each time the fluid cycles through the loop completely. I'm so hoping you kept this waste of radiators and a box fan intact purely for testing reasons, as it is genuinely brilliant! Ways you could potentially improve the rig though is to fit legs to it so it can be placed vertically so the convection effect can potentially come into play, and maybe an even larger (or additional) reservoir to just absorb more heat during peak loads during normal usage

*Next Video* Jay-"so i've bought this car radiator"

jayztwocents is actually three different rappers: Jay-Z, Too Short, and 50cent.

i would love to see a test with no fan turned on, and just with the 4 radiators (silent mode) if thats enough to keep it cold

Get a second fan for a push/pull set up and see how high you can oc this. Then see if you can beat Gamers Nexus fire strike 3D score.

"This is the dumbest thing I've ever done..." drill through a motherboard?

Should flip the whole rad/fan assembly so the air also blows air over the other exposed components. That much airflow would also cool the chipsets, RAM, the whole graphics card etc.

who's here after watching the video on LTT that went up today and remembered that this existed three years prior?

When did vaping become the standard for vaguely demonstrating airflow?

The "passive" cooling is the part I'm actually impressed by. Although it's not *really* passive (the pump is still mechanically circulating the coolant dynamic (water), a well-sound-insulated pump is going to be a helluva lot quieter than a case full of fans.

Wait until january, hook it up to a mining rig and heat the office with it.

JAY stay in this direction brother. love the channel man

6:22 that moment when he realized that someone is calling him and just immediately hid the phone. :DD

The dumbest thing I've done is listen to my attorney. Every time...

Yooooooo, I might actually do this when I custom loop. Imagine the acoustics when a passive loop keeps an overclocked system at ambient when it's not under a stress test

next project use a cars radiator

MONSTER---MONSTER GARAGE! THERE'S RUBBER TO BURN, SPARKS TO FLY, THE NEXT JAYZTWOCENTS VIDEO IS JUST. AROUND. THE BEND.

"This was a stupid idea" yeah but you're having lots of fun doing it. Also 32x120mm fans in a push/pull config might have been interesting. I have seen several cases with punchouts for external cooling.so many they expected this silliness.

2018: This is totally overkill and just fun to watch. 2021: Where can I get one?

Now start removing rads, what's the minimum rads you need to maintain ambient?

It may seem dumb to others, but to Jay, this is the smartest thing he's ever done.

There seems to be one major positive improvement on this one that you did not think about: Why not put the blocks in parallel? Currently, only the first heat dissipation unit works at max. The next block gets lower temps and drops in efficiency thus resulting in less dissipation. The resistive forces(static pressure) inside the blocks force the pump more: the series circuit is longer with more resistance to the flow. Again, make it parallel in the that way you will get the max possible efficiency out of each radiator at the given coolant temperature. Use a manifold and keep the loop length the same for each radiator in order to get a well distributed flow. Maybe change the pump or simply increase the flow too. BTW your current heat dissipation rating is somewhere from 30% to 50% lower because you are running the system in series thus dropping the temps and efficiency for each next radiator.

What you need is a refrigeration unit that makes direct contact with the coolant. I would start with a commercial diesel refrigeration unit of your typical semi trailer. It can reduce air temperatures down to -20 F.. But we're not interested in cooling air. I want a good sized plate fin heat exchanger that puts just a thin bit of aluminum between the coolant doing the cooling, and the coolant being cooled. Then we can test to see if airflow through the radiator makes it any more efficient or not. Directly cooling the coolant with a plate fin heat exchanger is a lot more efficient than cooling air, then using that air to cool your coolant. Of course, if you dont mind the noise and smell of diesel, you can eliminate the heat exchanger altogether and run the coolant directly into a commercial freezer unit - cooling the liquid down to -20 F. directly. At this point, the bottleneck becomes the surface area of the CPU. So, what we need a special CPU that spreads all the processing out along a square foot of space and a ceramic/aluminum lid for maximum heat exchange. Or perhaps a special motherboard that handles 16 separate single core processors - effectively increasing our heat exchange by a factor of 16. I think we can OC the chips to compensate for the performance loss of putting that much distance between chips. %*$# yeah!

Now that's some badass cooling

Jay to Linus "Bruh hold muh Beer" 🍺

These should be sold in stores you are a genius!

"so if you were interested in what kind of airflow we're getting" *vapes right into the god damn radiators*

Now you just gotta try it in Push-Pull config...

Video suggestion: water cooled audio challenge - build an over clocked gaming/editing rig, with the lowest noise emission level you can. Maybe challenge LTT or someone to fight you over it?

I like how the next playing video was "correction... THIS is the dumbest thing i have ever done"😂😂😂😂

You should do a 2022 version of this with today's hotter components!

How about a thermal image of the rads under load?

Jay: It's got absolutely no purpose or reason Me: *Likes*

I would like to see a video where you run the benchmarks on progressively fewer radiators until you find where the temps rise above ambient. IE could you get the same results with 2 rads instead of 4?

I run a Watercool Mo-Ra3 and love it. External massive rads are the way to go.In addition, a lot less tubing inside your case, pump and res also mounted to the rad. Functional and stylish and much better performing than equal money internal rads with lots of hassle and cramped space etc...

Next time ... Cool PC using A Car Radiator 😝😋😅

If this is the dumbest thing you have ever done, you need to try harder. :)

It's been years and every once and a while this pops in my head and I rewatch it...and It makes me want to do this in a full customer cabinet/desk.

Add a flow meter. You may need to add a pump in series. That's a lot more flow resistance than a typical custom loop.

Try it with a Delidded 7980XE! Seriously! You almost hit 5 on your chip, delid it and just do it!

Just do a car radiator alot bigger than those and 80 bucks brand new... Put a box fan 15 bucks at family Dollar works just as good and a lot cheaper

I just realized that the closed captions actually says “Jays $0.02” in the intro lol

That fan are cheaper than the noctua fan LOL

This just goes to show that you cant cool 8700k lol

This the type of shit Linus would do. I like it.

Lol. I'm watching this with captions on. In the intro when he said his name the caption said Jays $.02. I just can't stop laughing

this is the most beautiful thing i have ever seen. the i9's with 4090 will now be coolable

Should try that with a Threadripper or the Core i9! This is the more extreme ones to experiment with this!

Do more of this type of videos

Few things: 1) Soonish is a great book and Zach makes the ever funny SMBC webcomic series. 2) Their last name is pronounced Wiener-smith (yes, like the hot dog/penis) 3) I feel like this would have been cool to do with the car radiator like Linus did later.

I would have liked to see a longer test with the fan off. This might actually be a solid and very quiet solution to cooling, if you have the space for that huge array of radiators. I'm wondering how quiet these pumps actually are, and I'm amazed the pump is able to run the liquid through so many radiators.

Intel saw this and thought 'Nah, that's not enough cooling'...

You should test this >> Remove 1 radiator, test again e see the results. Remove another radiador, test again, .... So we can see the difference!!!!

This is still one of my favorite videos. You always manage to take "jank" to a professional level.

Air flow tester? Nah phil ripping phat clouds from a vape.

Would be cool to see this with more GPUs or even cooling multiple systems in the same room! How many gaming PCs can it cool?? :)

If it works, it's not dumb.

I really wanna see a delidded follow-up vid

I legit died laughing when I saw the 5 spaces for 4 fans after all that calculating xD

The air CFM is a function of the over all throughput. the fan is simply moving so much damn air that any loss of pressure between the blades has a negligible effect on the cooling capacity. now if you had some much thicker radiators with a much denser fin array it may the static pressure might be a more pertinent factor but not in this case with these puny (in comparison ) radiators.

Use the same 4 rad frame, and cover with the best fan types that screw onto each rad. 4x fans per rad, 4x rads: 16x little fans. Rerun the same tests.

Should do this again but with like a super crazy modern build. Watercool the CPU/GPU and Mobo.

What's cool (pun intended) is that it can function passively. You already habe the radiators framed up nicely, if you built a couple of stand off brackets and mounted that frame to the side of the PC, you'd have a passively cooled silent system with a giant bad ass radiator bolted to the side. I'd buy that for a dollar!

I have a suggestion : Why don't you build a case around this radiator :)

Before watching this, I'm wondering if what I'm about to watch is really dumber than drilling a hole through a multi-layer motherboard PCB.

Imagine if Noctua built a box fan.

This is actually a really good ghetto set up I would be down to do someday if I wanted to do an external rad set up and had a budget. Very smart idea

Almost as much radiator that the 1000D can fit.

What I learned from this: MORE RADIATORS

Stick the radiators together with 'Double sided Tape' !!!!!!!

The fart at 4:44 had me dead

never underestimate the power of our lord, the box fan, hallowed be thy name

I have wanted to do this for years! I've always wanted to build in WAY too many rads on a custom stand for a micro atx build and have one fan moving the air in or out of the enclosure.

💜DO MORE WITH THIS JAY💜

6:28 Phil and i test airflow the same way LOL

#JaysTwoCents rerun it with a delidded CPU and stress both CPU and GPU at the same time, then let us know the results :D

id like to see this setup with a delidded and ocd 7980xe. Doesnt that thing put out 1000w if ocd high enough? Maybe the pump couldnt even move the water fast enough in such an extreme case.

The best cooling solution i'v ever seen in a pc!! i keep this option in mind!!!

Next recommended video: "Correction, THIS is the dumbest thing i've ever done" gold

And home depot and Lowe's stocks sky rocket from the sudden sale of box fans.

throw this thing on a threadripper 1950x!!!!

This should be retitled as a D-5 Pump showcase. Watch a single D-5 pump thru 4 -480 rads and a GPU and a CPU!

Was going to build an outside (of the house) small automotive radiator system piped through the wall , with an temp controlled fan , to run multiple PCs . But after seeing gunk and gasket degradation covered on various channels now thinking about a closed loop system based on huge heatsinks. Will wait for the next gen of air coolers to decide as my idea look like it might be overkill as the tech develops.

"It still gets pretty warm" *CPU is almost at boiling temp*
