14900k vs -50c Dry Ice 

Hey Jay! We met on the Disney Wonder - I'm Ryan the bartender from Cove Cafe, sorry I missed you on your 2nd cruise, I heard you had asked after me. Was great to meet you mate, thanks for the chat!

100% more Jayz Science channel.

The reason that you are my favorite tech RU-vidr is because of your ability to admit when you are wrong, admit when you don’t know everything about what you’re doing, and the fact that you truly show genuine humility and show the desire to learn when you ARE unsure about something. Don’t get me wrong, you know ALOT, and I’ve learned so so much from you, you’re extremely intelligent and I respect your intelligence a lot, but at the same time, You don’t act like you know everything, because nobody knows everything. Through this you show that you’re just a normal human being, which makes you much more relatable. I love your “learning experience” videos just as much as the ones packed with information that you already know like the back of your hand. This video In particular isn’t really either, but I just wanted to leave this comment as I binge your latest videos to catch up after a busy week. You just seem so genuine with everything you do. The way you talk to the camera, the way you talk about what you’re doing, and the way you explain things and break stuff down for people is unmatched. We love you Jay.

For the vacuum system, I’m sure it was initially vacuum but then the evaporating nitrogen filled the tank, so it became a nitrogen purged system the same as binoculars or rifle scopes. So the other components were still cooled by the nitrgoen but there was no water for condensation to occur.

Hey Jay, just wanted to say thank you for the years of enjoyment you've given me. Started watching on an older channel of mine when I was around 13 and now I'm 21 and you've given me a lot. I'm headed towards a Systems Administrator role in IT. For the hobby aspect of things you've definitely hit a soft spot.

Captain Pedantic chiming in. You wouldn't be evaporating money by letting that dry ice go to waste, but rather sublimating it.

Some friends and I did this in our garage with a 2.4GHz Northwood P4 back in the day. We got it all the way up 3.6GHz. Though, our pot was hand mig welded and zap strapped to the board....with no condensation protection for the board, just AC insulating wrap for the pot. This brought back some great memories. Thanks.

You don't necessarily need a vacuum to stop condensation, you just need no moisture in the air and for that you can for instance keep the system in a glove box under a continuous nitrogen purge (which will be easy when using LN2) or continuously push dry air in the box

Random thought - CPU contact frame instead of the factory bracket? Might allow you to use the larger pot if you wanted to see if you could get a bit better results.

Why not put the nuts on the other end of the rods before putting the rods onto the m/b ?

Time for a sub-zero Alcohol loop. ALL THE DRY ICE.

Crazy experiments, always nice! What you're seeing is not the acohol boiling, you're seeing sublimating CO2 bubbles coming out. Dry ice is -78.5 C in a pure CO2 atmosphere at standard pressure. In air its up to 20 C colder. We published that last year after I finished my master thesis on it. Btw theres lots of optimisations can be done on those pots tho, their insides are trash for thermal transfer. At least there's those holes to give more surface area than a bare shell would give. Tho with the very viscous cold IPA it might not improve much, at least way less than the very low viscosity LN2.

Finally Jay went back to the cool stuff. Love these videos

I literally just finished watching your last dry ice cooling video!

I wonder how dielectric oil would take the cold. You can submerge the board in the oil, then cool the whole container with the board and oil in it. You wouldn't have to worry about condensation. I am just not sure how cold it can go.

I'm not too much into overclocking myself, but I'm into when you do it like this. I get to learn something and is fun to watch. Definitely do more like this!

8:05 - and thus, Jay created a new version of MSI afterburner

I love the mad scientist experiments.

Why not use argon instead of a vacuum, its heavier than air so will fill a box that a motherboard is in, its dry so no water will condense out and its easily available from welding suppliers.

I love this content. Thank you for sharing!

Jay, you should do some science with the Thermal Grizzly AM5 direct die waterblock

I love to see you guys have so much fun with these series, reminds me a bit of Braniac in a way - but tech

I love and appreciate how this channel stayed the same and remained consistent over the years. From the early days of Jay by himself in his home office, to now having a dedicated office and a crew - the quality of content and the humor that goes with it, it's like I'm watching the same good old Jay from back then, only amplified. It's awesome! It's always interesting to watch, and never boring. Thank you for the great content. God bless!

I wanna see you run chilled alcohol through a water cooled system!

So good to see back to these types of videos, love you Jay!!!

I do enjoy your crazy over clocking stuff. Even if it does not work. As I'm never going to OC my rig, it's cool to see someone else do it

You want more stupid ideas? Sorry, I don't have any, but I LOVED how fun this video was!

I'm loving the Professor Jay video series!

It's amazing that as much unintersted as I am in any kind of overclocking I still love seeing you doing this kind of videos. I'm sure that in later videos you'll find a way to solve some of the problems with dry ice and lN2 and try it again.

Regarding the "vacuum" system to control moisture. I can foresee problems with the rest of the system that depends on air cooling (including components that wouldn't normally need to be cooled). A thought that I have had in the past was to build the PC inside a sealed case, then completely dehumidifying it to 0% humidity, and then providing a closed loop radiator within that sealed cabinet to provide cooling (absorbing rather than radiating heat) to the components that aren't cooled by a sub-zero (something other than water) loop .

Well done on your experiment sir. Look forward to the next one.

I love this series!

Jay, consider putting sub-zero rigs in a box or fish tank with a couple containers of dry ice or liquid nitrogen. The carbon dioxide or nitrogen will be colder and heavier than ambient. This can serve as an effective barrier against condensation as the warmer air will constantly be pushed away by the cold gases. Ethanol (think Everclear) has a lower freezing temperature than methanol or Isopropanol (isopropyl alcohol from the drug store). Their dielectric strengths are similar enough for your purposes.

Here's a stupid challenge you could maybe collaborate with one of the engineering/building channels on: instead of using fans to move air over radiators or heatsinks, move them or the entire PC through the air. Could you match the OC of a normal watercooling loop or will the computer be torn apart?

@6:56 "there no active cooling on it", pans to it with 2 fans pointed to it. Never change Jay

I think videos like this best define your channel, strong passion for what you do.

These janky screwing around videos are my favourite! Have you thought of experimenting with mineral baths for cooling? I wonder what combination of submersion coolant and cooler/ underwater fan combo would work best? I'm imagining a setup where you leave your CPU exposed, and just have a fan pointed directly at it. That way you remove the extra contact layer (metal on metal,) that you would need with a LN2 or heatsink/water block setup. In fact, is there a world where you can create a watertight mineral bath tub that would allow your liquid to directly come into contact with the CPU lid? You could pump mineral bath fluids with a regular pump.

ive got an idea for ya: not vacuum enclosure, but filled with same CO2 as in the dry ice, and have it circulated via fans somehow, that or nitrogen gas, if N2 is used

I love these videos! Please do more! I don’t have any suggestions though

For the E cores, you want to watch the ring when you touch them (May have to do this through the bios if XTU doesn't have a ring option). You may not have had the BSOD if you lowered the ring, as I've personally found that a higher E core clock destabalizes the ring when that is near its limit.

Whoooooo let’s go Jay! Love you bro!

You crack me up. I was one of the original customized store bought water coolers in the 90s... I just wanted to play quake with zero latency. In the bay area I learned about condensation and just put my computer on the side blowing an air conditioner across my radiator in winter with SF fog. I had to do some radio shack stuff. We had to use jumpers. I blew up more boards than chips. I was running ATI graphics with a voodoo 1

On the Xtreme Systems forums, good 12 years ago, there was a thread called "Goliath Triple Cooling System" of a guy building a computer case with 3 separate cooling loops. One loop (chilled liquid running at -40C) for CPU and dual GPUs, second loop for cooling the air in the (mostly) air-tight case to -40C as well (so that any moisture condenses on the heat exchanger and the PC only sees absolutely dry air, so no frost/condensation problems on expensive parts) and a 3rd loop, this time "plain" water cooling, to cool HDDs and other peripherals that don't run sub-zero. Sadly, the build was never finished.

1:12 the fine thread is nice because it gives you fine adjustments. May I recommend putting a nut in place before you cut off the top of that all thread. When you unthread the nut it will take any burrs out and make reinsertion of the nut easier next time.

i love this kind of experimental idiocy! this was a lot of fun

Actually impressed with how well the dry ice/alc worked - I do need to get my 11700k under water at least (still rolling 5GHz all core 1.3vCore was at 1.40 since I just did a dirty OC).

Jayz two cents ultimate gamer between you guys in various games. It’s been awhile since something like that.

Nice work!

Keep at it, the origin of knowledge is experimentation and documenting the results.

always loved and enjoyed the LN2 content and the RIP Steve saga was amazing.

Jay’s dryice adventures marathon just dropped!!!

Just want to say, I love this crazy stuff you do that I could never have done. Cause I can’t f***.. Mess around with my stuff like this 😂 It’s good fun to watch honestly. Next step is to put your PC in your car and drive as hell to see much friction it can take before giving up 😏

You could jury rig a loop on the cold side of a AC unit for the next experiment.

Good point about not using blowtorch with IPA, probably wouldn't do the 3D printed piece any good either...

i enjoy these little science experiments tbh

hey jay, easy tip with those threads. put a circular cloth or even a thinker rubber band around one side of the bolt and your drill in the same loop, then you can just use the drill to screw/unscrew

Air conditioners dehumidify the air, one could try making a duct to blow directly on the board/socket area to help prevent condensation from forming, freezing, and melting.

The liquid co2 post I did the other day, still don't know what if the system would survive the over 5 bars needed for that, but IF it does, then you may be able to use that thermal exchange medium and run it through a refrigeration system... run it down to -30c and keep it there... might need a unique paste for that though XD

Love to see some Jay extreme overclocking.

A video of you using refrigerants in a water cooling setup. or a pc fully immersed in mineral oil like they used to do back in the early 2000s. or a video on how to bend your own copper vapor heat pipes for custom made heatsinks.

I love the "extreme" overclocking type stuff. Would love to see how hard you can push an AMD CPU as a comparison to this video

Heat transfer can still occur via radiation in a vacuum. That being said, what you could potentially do is seal the chamber and use dehumidifiers to remove the moisture in the air.

Hey Jay! Cool tech tip for YOU. On those long, threaded rods you can take a small drill and set it opposite the way you want to turn the nut you're screwing, then hold down the trigger (Go at your own pace) and the chuck will spin against the nut, spinning the nut. Smaller drills work better, especially if their chuck is rubberized and not plasticized.

please try the same setup and drop into a shallow mineral spirit bath, just enough to cover the components with the pot being the only thing exposed so you can pour in the alcohol. And chill the alcohol as much as possible. What will the cold exterior of the pot do to the mineral spirits? If a problem build a mold to pour epoxy as thick as you need to give it a barrier.

how about using a sealed box with a mobo inside with a "shed load" of desiccant to absorb all the moisture in the box, so with the LN2 pot attached less worry about moisture messing up runs. :D

You could use a rag to slide the hold down nuts much faster. I learnt that from construction workers putting lug nuts on long bolts.

I was wondering after the last video if using ammonia in the loop would work. It’s what is used in the cooling of spacecraft to conduct heat.

1:36 You know you can put the nuts on the other way, and then put the rods in place

do a video just going through all the weird/cool stuff you've collected over the years!

Does anyone even care if Jay's experiments work or not? I don't lol. It's fun just watching him try stuff!

Hey Jay, have you ever thought sbout torque renching the mount down for even spread? & potentially testing to see what torque provides the best contact?? Love the vids btw

I love when Jay gets the XOC bug :)

Try this. Mineral oil pc, with the lno2 funnel suspended out of the oil. now drop dry ice into the oil, it has a freezing temp of -30. this way you can cool the motherboard, and not worry about frost. after that just use the lno2 like normal, no shorts because the oil does not conduct electricity.

multiple loops and rads with TEC's intersecting each loop, so each loop cools the liquid down as it goes through the each rad.

Cougar has a really nice new glass case that I think you could do something f'ing awesome with. Just saw it yesterday.

Have you considered that it might be almost as effective if you have a very good plate, and a sort of liquid cool to a chamber chilled with the dry ice or similar? use something like car antifreeze so that the liquid won't ice up, and you might have a very good way to apply extreme cold (-20 or lower) to the CPU directly. You might have to use a real pump to get things moving though.

11:54 I definitely heard "We dont have much time" in Arnie's voice as the T-1000 is on the floor in pieces melting back together from the liquid nitrogen. Weird association I know.

I would like to see you all 3D print a computer case then build in it. Might give you some ideas for the case you are going to be helping to design.

Jay turned that cpu into the T-1000 from the end of terminator 2 in that little RU-vid short he did, can’t wait to see what happens here

MOAR videos like this please. Especially more Nic and Phil. Also intrigued to see if Kingpin can bring some real attention to PNY in the US. Edit: stick your alcohol in the freezer first so it's not room temp when you dump it in.

More mythbusters ish stuff please. I miss that and this is so close to it sometimes. Keep the crazy random experiments coming.

In a vacuum, radiated heat should take good care of passively cooled stuff, as there is no longer an air blanket around them to insulate.

These are my favorite eps.

jay, rubber band on the thumscrew get a bolt and chuck it into the drill stretch the band between the two and turn on the drill SLOWLY and then ramp up as needed and it'll thread down (asuming there are no issues with the threaded bar

Insert the threaded rod into the chuck of your drill and go nuts. It works a treat. 👍😃

Have you ever considered building in a dorm fridge as a case?

how about making a functional chilled loop, something someone could do at home as well. keeps the loop cold but no condensation

Have you thought about mounting the MB vertically so that the condensation and alcohol drips away from the board instead of on to it. It might buy you some more tuning time.

These are great fun.

That was cool..maybe with Freon will be much better next time😊

I miss the old air conditioner days. Not as extreme but still fun to watch him experiment.

@jayz, explain all the upscalling techniques, frame generation and stuff like that. even I have problems understanding them

Oh come on Jay 😂 it’s almost the 4th of July 🧨🧨

Jason the science guy. Jayz! Jayz! Jayz! 👍

Go to a cold storage with -40degrees Celsius and do the oc there you can do gpu,ram and cpu at once just take also a big af fan for condensation with you

A minor point, but dry Ice does not evaporate at room pressure. Dry Ice sublimates. Evaporation is a phase change from liquid to gas, while sublimation is a phase change directly from solid to gas.

love it!

You sir are insane. But wow what fun! 44098 is insane.

JAY! Try using 189/190 proof Everclear if you can get it in your state. Ethanol has a slightly lower boiling point compared to IPA (not the beer) at a whopping 7 degrees F lower but evaporates slower. Don't bother with acetone BTW. Evaporates faster than both of those and much more flammable.

Hii Jay & team, Love the videos. Have you thought about doing some more content on older hardware? For instance, Looking at Old HDTC Cpus like x58, x79 and their unlocked Xeon counterparts? Maybe have a look around how they come against modern hardware in productivity and gaming. Plus don't forget how far you could push some of these Cpus just using Air 😮
