The 6.9GHz CPU - LN2 Cooling

[@linussebastian6053]

Couple points! Thank you Nikolay Pelov and linuxgeex At this low a voltage, the motherboard should never arc. Also, the true thermal barrier isn't even the increased resistance. It's the reduced impedance due to increased quantum tunnelling as temperature goes up, which increases leakage current, which is the majority source of the increased heat once you get into thermal runaway.

im working with cryogenics for work and the samples we are working with need to be handeled in LN2 at all times so seeing this i got some ideas. If you put the motherboard in a big container, the gas nitrogen (from the boiling) would fill it because it is heavier than air and you would not have air (which has all the moisture) around it. If you have a university or research institute around, you could think about contacting them. Cryogenic work is quite common nowadays and there is probably some experts around that can help with this

[@pwnmeisterage]

These guys handle some ridiculous materials. They do some ridiculous electrical mods. They engineer all sorts of ridiculous hacks and workarounds. But they insist on using "common" consumer parts in "common" consumer conditions. That means a computer on a table in normal air, no complete immersion, no vacuum, no exotic environments. Dunno why, exactly. The hobby is cutting-edge math, science, and tech on one hand. It's unscientific bumbling on the other. It's ruthlessly competitive on one hand. It's team collaboration on the other. It's methodical experimentation and calculation on one hand, it's reckless gamble on the other.

[@shanewilson3653]

To add to Groentje92 comment: Make the container out of 30mm plexiglass then enclose the top. whole thing rubber sealed. Add a flask with a tap to allow the topping up of liquid nitrogen. Add a vacuum pump. this will allow the chamber to be pulled down to a lower pressure, lowing the boiling temperature of liquid nirogen, allowing even colder temps. Also might be worth adding a 45psi burst disk,.. just in case of over pressure even if vaccum pump fails at some point.

a cool extention of something like this could be to put the whole system in a pressurized nitrogen atmosphere so moisture isn't an issue then use a cryogenic heat pump similar to the ones used to make LN2 as a cpu cooler by maybe using LN2 or helium as the cooling liquid. have a raspberry pi or the like managing flow rates and temps and it could make one hell of a server (wouldn't want a set up that big on a desk so in a rack it must go)

[@Deviated09]

The problem is, the action of the LN2 boiling rapidly is actually what sucks out so much of the heat. It pulls a lot of thermal energy out from the pot to go from the liquid to the gas state. This is actually very much how freon(r134) in our AC systems works, the transition from liquid to gas, and back, makes it able to absorb and release that heat so efficiently That's a really neat idea tho, I wonder if there is a way to implement it in a moisture free pressure vessel that still allows the energy transfer as efficiently(maybe more?)

[@DuckMan77]

As was said, you REALLY don't want gloves or even socks when using LN2 for OCing. LN2 isn't really THAT dangerous assuming you know what it does. Movies make people think it'll freeze you instantly and that's just false.

[@DuckMan77]

To give a little more context as to the dangers of LN2, it has 2 primarily. First is its displacement of oxygen causing asphyxiation (don't breath the gas). Second is its cold, but when touching your skin it due to the temperature gradient causes the LN2 to flash directly to a gas with a sort of barrier forming between your skin and the LN2. If you put on gloves this doesn't happen, it soaks into the gloves and super cools the gloves leading to burns from it. This will happen with socks and other fabrics too.

@Linus the true thermal barrier isn't even the increased resistance. It's the reduced impedance due to increased quantum tunnelling as temperature goes up, which increases leakage current, which is the majority source of the increased heat once you get into thermal runaway. That is what will damage the CPU, and that's the reason for throttling. Well... unless you're throttling before you melt the board's power stages or power delivery traces. We're at that point now where some mobos will fail before the CPU!

[@someonestolemyname]

[@jenda386]

@@someonestolemyname I was also very confused, as resistance of semiconductors indeed goes down with increasinig temperature.

[@nickpayne1182]

Ah, this is the post he referenced at the top! Thank you. Now I know that silicon has a negative coefficient of resistivity, which I think explains why he said that the board doesn't like to power on when it's cold- The impedance of the silicon is too high when it's cold & doesn't allow enough current flow.

[@linuxgeex]

@@nickpayne1182 At the frequencies they're pushing, 99% of the chip is a series of connected RLC tank resonators being coerced into operating literally in harmony. For best efficiency those little tanks are designed to operate happily in a given frequency range with a given amount of power based on capacitance, inductance, the driving voltage, the driving frequency. The rate of change of voltage is based on the resistance (metal and semiconductor) and impedance (metal and semiconductor.) The resistance of both goes up quite linearly with temperature. Impedance on the other hand is quirky, lol. As the capacitance and inductance deplete they induce current flow which increases impedance to the depletion of the inductance. Higher temps decrease that impedance but prolong it. Net effect is that the transistor takes a little longer to switch, and so requires a higher voltage to switch fast enough to keep up with the clock rate, hence why cooling and under-volting allow you run higher clocks at lower power. Quantum tunnelling does the opposite. It's behaves similarly to how an avalanche starts thanks to vibration. The electrons want to get from A to B. Semiconductors can be biased to operate as either conductors or insulators. Insulation works to prevent electron movement by presenting a uniform wall of electron shells perpendicular to the desired path of the electron(s). As the insulator's molecules heat up and shake larger gaps intermittently appear in that wall. When the gaps get large enough, the odds of electrons jumping through them increases (quantum is all about odds lol). That shakes the molecules even more, and soon you have an avalanche of electrons migrating where they shouldn't, plus more heat than was designed for. If the heat is sufficient it can break molecular bonds and the electrons will start pushing atoms around, aka "electromigration". CPUs have heat sensors to make themselves throttle before that happens, but those sensors can fail and allow a CPU to self-immolate, sadly, and that's part of why TDP exists - the CPU will also throttle above a certain power usage window as a backup failsafe anti-suicide measure. Intel K series processors have that safety feature turned off... you pay for less safety lol.

[@starstreamir3817]

Another possibility for potentially avoiding condensation altogether would be to do what you're doing here with the extreme overclocking inside of a walk-in freezer. The cold air tends to be dry and has the bonus of keeping everything cool, but not ridiculously cold. The LN2 would still boil in a walk-in freezer. You just may need to make use of a heat gun or that torch a little more. If you did this inside of a sub-zero environment, you wouldn't need to go to the trouble of building a vacuum enclosure like the one I described in my previous comment. I'm sure you could find someone who would let you borrow their walk-in freezer for a few hours. ...Or you could possibly even buy your own if you wanted.

Just an FYI (months later) you'll probably encounter the leidenfrost effect with liquid nitrogen. Effectively the liquid boils away and shields the core from cooling; this is why you can dip your hand in liquid nitrogen. If you convert to a pumped/flow setup you will avoid this.

Alex and Allen: "talking about overclocking" Meanwhile Linus: UIIUUIIIIIIIIIIIIII

[@joshwaaam]

Absolutely, positively insane! Could you somehow run the pc in a vacuum removing air to condensate? Cool stuff guys!

[@corbing7786]

I would think the process of removing air from the vaccum chamber would damage components

[@anthonykoller4459]

If you remove the air and turn it into a vacuum like out of space, wouldn’t the metal components weld to each other and the liquid turn to jelly and evaporated?.

[@brreeaad]

I would guess the latent heat energy absorbed when the LN2 boils away is important for keeping everything cold enough, and a vacuum makes the boiling point too low

[@meowmeowmeow594]

@@anthonykoller4459 This only happens with identical metals, and very clean and smooth ones at that

[@meowmeowmeow594]

They could, but the issue would be removing heat fast enough, considering it's a vacuum.

I'm sorry Linus, but today is 09.06. 06.09 will be in 3 months in September.

[@VexChoccyMilk]

You guys should try a raised reservoir feeding into the pot governed by a valve that you can modulate the drip rate to keep the rate of cooling/coolant use more accurate.

[@md.sadidhasanmurad2347]

aah a stable overclocked setup is a blessing!

[@DeathBaseTURBO]

And for the rest of the world, we require a 9.6ghz overclock

[@0x8badf00d]

You mean 2022.6 GHz? ;-)

[@paulbrooks4395]

You guys should do a chilled dielectric liquid cooling, using some of that 3M liquid that’s used for server immersive cooling.

[@EchoConstellation]

Hmmm, how cool would a Novec submerged PC with a LN2 powered heat exchanger to pull heat out of the Novec be? I think Novec 7000 boils at 34° C but freezes as low as -122° C. Submerging the test bench in Novec would remove any condensation risk. It’d also likely stay colder way longer since Leiden frost wouldn’t be an issue, and a few liters of Novec at -100° C would be a massive thermal sink.

[@KeinNiemand]

I really wish it was possible to buy novec.

[@EchoConstellation]

1:33 - we used that trick to quickly "sweep" the lab floor! If you pour nitrogen onto the floor, it propagates in a "wave", carrying dirt and litter until it hits the walls. Then you can just sweep it. Kinda like vacuuming, but much more fun.

[@ThePaoligno90]

And also (and this is maybe the 5th time I write this) you CAN (and should, it's not difficult) put your motheboard in a controlled atmosphere (i. e. a box with a Argon or Nitrogen gas flow) so there is NO MOISTURE in the air. In the research world this is done for example to protect samples exposed to radiation from oxidation.

[@Jeroensgambling]

It's expensive to run a setup like that.

[@commandertaco1762]

Linus: You know who never fails? Our sponsor MSI! Me remembering MSIs PC prebuilt: "That's a lie lmao"

[@itIsI988]

It's also a Ventus so it'll probably fail to cool the GPU properly...

Only time I've messed with liquid nitrogen was with overclocking a old socket 754 sempron i think 2800+ which was stock like 1.6 ghz pushing it too 4 or 4.1 ghz On a poor matx gigabyte board with an nforce chipset. At university ca 2013 or 2014 with a ocz 650w powersupply hooked up too it i think. Agp slot on the motherboard & integrated graphics was first used but that stopped showing a display after a bit (go figure lol.) So a random agp card was used instead. Ram was like one or two sticks of 400 mhz cl2 ram at 512 megs or 1 gb in total. Pointed a fan at them & fan at the vrm which was completely bare btw, no heatsinks at all on either of them. Classmate got too work building probably one of the most ghetto liquid nitrogen pots ever... Step 1: Regular size pringles can, don't remember if it was either sourcream or a regular one. Step 2: Gobs of solder on the bottom of it too raise it up around the motherboard a bit & get a sort of cold surface plate, think it was leaded solder, might have been unleaded or a mix of both. Ofc making sure not too melt a hole through the pringles can bottom which is kind of aluminium foil ish so close enough right ? Which also didn't crack from the cold & worked surprisingly well after some sanding too smooth it out flat which took him probably like 35 minutes or so lapping it fairly smooth too the touch & flat. + ofc thermalpaste later used for better contact. Think it was MX-2 or MX-4 & caked the cpu in it. Step 3: For mounting the pot somewhat more rigid then gravity, 4x holes where i think wooden sticks or pegs threaded through, zipties through the backside of several mounting spots on the poor motherboard too tighten it down doing it gently a bit at a time too keep it sticking down somewhat squarely on the cpu while making the mounting tight against the cpu. Ghetto as all hell but worked surprisingly well enough too mess with & get it too boot into the bios at 4 ghz after all, probably not an overclocking record by any means but fun too do anyway. Also filled the pot with bottlecaps & other random metal garbage from the workshop & a box of random pc screws too absorb & keep the nitrogen from dissipating too quickly, we surprisingly due too the Jank mounting we did had nearly 0 issues with issues booting up having readings at like -102c or so, but might have been the sensor just completely freaking out as well. Ofc we used paper towels & a bunch of other stuff too insulate the board from any moisture the best we could together with the fans. If we had a pci ide interface card we probably could have managed too make the poor thing boot into windows but the onboard controller & probably most of the chipset was noping out after like 2.6 ghz already & we kept upping the fsb as long as it booted into the bios after maxing out voltages on chipset, ram & cpu lol.

[@Jeroensgambling]

Ive reached 4.1Ghz or 4.15Ghz too on a sempron; using a phasechange keeping the CPU at -45 on avg. Was a fun day. Installed the phasechange later ontop Ati 2600 pro which had stock clocks of 600Mhz, soldered all caps with larger or better ones, installed a external PSU instead of being fed through the PCI-E Bus, and managed over 1260Mhz core clock lol. Once i turned the voltage way beyond 2.2V the sparks just flew out of the back of the card and the party was over.

You know what else helps? A well sealed room and a dehumidifier to pull more of the moisture out of the air. Won't get it all but if there are any holes in your moisture barrier it will reduce the risk of anything getting too wet

[@MA-jz4yc]

Does splave have a world record in strongman too?

[@nonono285]

Could you overclock in a closed chamber filled with some inert gas which contains no moisture? Or what about overclocking with LN2 while the motherboard is also submerged in some kind of oil?

[@meowmeowmeow594]

That's a good idea. I wonder what you could use that stays liquid at cryogenic temperature, without cavitating wherever the heatsink is.

[@user-rr6ct2sv2u]

Cinebench is a very good benchmark for comparing true potential. I wonder however how crazy performance would be for certain games more limited by CPU performance while having a high end gpu. How high can those fps numbers get ;)
