Back in the mid 2000s it was common to cool a computer using a heater core from the scrapyard, but as those have become harder to find and water cooling components became easier to find this fell out of fashion. Could the old ways have been right though? Is it still cheaper to use a heater core to cool your CPU?

    Sometimes, it appears that Kyle thinks he works in a real place, and not this wonderful chaos lol. Great work!
  • @lipot69
    It's funny that Kyle tries to be a voice for reason and still goes along with the plan. Need to have more videos like this with him and Alex.
  • @IsaacAllwood
    Absolutely love Kyle slowly losing his mind while Alex and Linus are just having the time of their lives.
  • @IrisCorven
    My god. The combo of Linus, Alex, and Kyle is the most amazingly chaotic jankfest I've ever seen. I love this.
  • The Alex and Kyle: Chaos Enginners duo has to be one of my new favorite dynamics of LTT.
  • @TheRedThirst
    Kyles concern for the 4090 throughout the install was heartwarming
  • Seeing these three work together is like watching Hammond, May, and Clarkson work together on a car
  • @viccie211
    I love the dynamic Kyle brings to these kinds of videos! He fits very well with the vibe of Linus and Alex
  • @jetscapo9737
    Hose clamps def should've been utilized here. Not only for performance over zip ties, but for the whole aesthetic/theme of car components/hardware meets PC components/hardware.
  • @zapawafyt
    What a combo. Anything with Kyle is gold, the back and forth with him and Linus, and throwing the jank that Alex usually runs with.. chefs kiss
  • @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.
  • 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.
  • @justalpha2396
    God I love these types of videos. By far one of my favourite styles of video from LTT. I just love imagining someone pitching this idea and everyone being like "that sounds stupid, let's do it." Whenever engineers get free reign to do whatever they want you either end up with something amazing or at least some great content. Keep it up guys!
  • @SakosTechSpot
    Linus using wrong or slightly incorrect parts is very relatable. Many times I use whatever I can find around the house to make a project work and sometimes it's not perfect, but it turns out well enough. Never stop doing this LTT.
  • I love this. I'm old enough to remember hearing about people doing this stuff but never did it myself. Very cool to see this from a modern perspective
  • These crazy improvised build videos are literally my favorite LTT content by far. And the comedic moments between linus and alex are great. this is a gold tier episode ngl
  • Wooh, I love that the Jank Duo has expanded more consistently to the Jank Gang! Having both Alex and Kyle on these videos is fantastic!
  • @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.
  • @adamkares7549
    I remember getting into liquid cooling right when Danger Den started selling purpose made rads, I still have their original chrome 120mm. I always appreciated the pioneer builds from back then though, car pars, fish tank parts, home made waterblocks made of brass slugs with hand drills, probably used literal garden hose. Today's market is truly an embarrassment of riches Good ep guys, no one has a better "wtf is Linus doing..." face than Kyle
  • @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😊
