    They should see if using this radiator in a ice water bucket would be better than a standard rad in an ice water bucket

    Just use a car fan as well at this point lol, you can use a push/pull dual fan setup as well

    i'd like to see this done with some better adaptation of the radiator so it isn't pouring water everywhere. i bet this would work pretty well honestly.

    THE BICYCLE INNER-TUBE WAS ALREADY A TUBE! COME ON!!! just use the whole bike tube instead of reducing it to computer tubing.....

  • PongoXBongo

    With a radiator that big, ditch the case fans and just strap it to a box fan. Maybe use a piece or two of window bug screen as an air filter.

  • VMEcycle6

    reminds me that episode of silicon valley, which they were serving millions of viewers watching a man drinking his own urine, while their server was on fire. 🤣🤣🤣

  • VMEcycle6

    6:35 just get a box fan😅😅


    Linus obviously forgot about the whole room water-cooling setup with a radiator on the roof when he made the title

    I watched 13:57 got frustrated seeing that you guys never made a plan to fix the water dripping from the cable it's not a hard thing to do.

  • Alex

    Yeah, the transmission cooler works by exchanging heat from the hotter oil into the relatively cooler water, so you're wasting your time there.

  • William Bland

    Once inspired by a younger Alex and Linus, I made a mineral-oil PC. at the time I was a tech for a car dealership, and radiators were easy enough to get ahold of. With some proper connections, I was able to make one into a cooler for the oil. 3 small things done differently, and this radiator build would have been even more successful, but probably not as funny. Love the "Mad Scientist" videos, always a treat and an inspiration.

  • smegskull

    That radiator could just fit as a side panel to my HAF-X.

    everytime they put out a 'crazy cooling project' I still think of whole room watercooling with the window-mounted radiator. Which looked fairly similar to this thing

  • DG

    I remember some Russian guy using Volvo radiator for cooling in the early 2000's.

  • MrGrebgnet

    You should try to water cool a pc with out fans by hooking up The reservoir to a running tap and dumping The water after The heat block into The drain!

  • Kody Miles
    Kody Miles

    this seems like a completely practical way to cool your pc, you just need an extra 3 people willing to damage control the entire time you use it

    There are a lot more important problems with the approach here, but the one that really got me was: why not put the brown fans in a neat row in the middle?

    I wonder if they thought about hose clamps instead of ducktape. _keeps watching_ let's see where this goes.

  • Von Droid

    i'm surprised they've never heard of the product called " Magic Wrap ". I've used it to temporarily seal everything from automotive to plumbing joints - even works on air compressor hoses.

  • gamedeathmatch

    Seems like most people in the comments are on the fence with this video, you either liked it for comedy or wanted to see a more polished version. I am in the latter camp I want to see a well thought out idea that has a logical implementation/testing

    I actually did this in 2014. It worked. The tower reached up to the ceeling. I needed to disassemble it and rebuild it because we moved. The radiator(audi tt) is still cooling my cpu and graphics card( ryzen 7 1700x and 1080ti.) Temps under full load are under 70 celsius for both. And you only need two 230mm fans for airflow. I use 2 laing ddc pumps and copper piping

  • scorntooth

    did u guys consider installing a single standard box fan to the side of the rad? might be better lol

    Just think, if they would have used one of their many 3d printers to print a reducing bushing instead of using a innertube...

  • SaintApoc

    if you had put a FLIR on it while putting water through you could maybe see the loop. Also, this thing needs to be mounted in a window with one giant fan

    You needed metal clamps for the hoses, zip ties don't get tight enough.

  • 10cody7

    the real stress test would be trying to actually use this damn thing

  • 〈/†〉[Nick1921945]〈♥☺♪♫〉

    Why was there no hospital beeping, and respirator noises during the entire half of this video? You guys spent like 2minutes planning this all out. Insane.

  • Eric Glandon

    You have an engineer Linus do this correctly. While fun to watch it would have been nice to see it done seriously

    This is so painful it isn't funny, why not make the loop correctly instead of just dumping water everywhere.... they make adaptors and proper clamps

  • Coaxill

    You guys weren't even trying this time. I kept thinking you were about to get your shit together and fix the leaks, but a solution and a proper test never materialized. And while the frame setup was a great idea, it had no reason to be on top of a case like that, and you could've taken it down at any time. I wanna see you revisit this and do it justice. I love your videos Linus, and I think you'd appreciate the honesty.

  • PD1JAP

    OMG inner biketube.... why not 3D print something to connect GOOD....

  • m4ko

    Linus. Your conclusion is false. You rushed this and constantly poured fresh cold water into the system. You would need to run the stress test for a long time without changing water until water temps don't increase anymore. Cool idea. Bad execution.
