  • Here comes a comment from PhD. 1. Some obvious stuff: When you put in contact two media with different temperature the heat transfer will occur making the temperature (difference zero (in a infinitely long run, that's what thermodynamics is, its about static equilibrium states). The resulting temperature will depend on heat produced on cpu side and heat removed on coolant side (cooling being produced by phase transition, i.e. sublimation). However it will be reduced by the heat transfer due to limited heat conductivity - remember that you are using high-glycol mix with quite a low heat capacity and conductivity). 2. Hence we need to find out the real temperature on cpu block's bottom surface and water going in and out. More thermal probes, Jay! This will show how well the heat transfers through your cpu block. From this you will see if you need to increase the flow rate or maybe use a custom block. If you see the water temperature difference (Tin-Tout) is low then it means you have inefficient CPU block. I strongly advice against using thicker plate - it will not tip the resulting temperature, it will saturate at the same point. Instead you need to increase the heat transfer efficiency by creating a custom block with long path (=high area of heat transfer). Here's the idea: Mill a 6 mm deep 3 mm wide channel in a 9 mm copper plate forming a long labyrinth-like path. It won't lead to a high flow resistance due to 18mm2 channel cross-section and on such a big IHS can get you a really good heat exchange. Microfins are for watercooling, where heat conductivity, capacity and viscosity are different. 3. Perhaps you're limited by the heat transfer though the thermal paste. Go for In-Ga eutectic (Conductonaut), even if it freezes you'll get a nice metal conductivity. And it probably won't even freeze. On a technical side - you can probably dip a metal cylinder (or a bent 2" metal pipe) filled with dry ice into your water bucket, the heat transfer will go through the metal wall but you won't have the bubbles to deal with. 4. Looking forward to see some experiments with In-Ga eutectic used as heat transfer liquid instead of water. Yeah, it's corrosive and messy but it's another league of heat conductivity.

  • I have a Stupid ? forget the loop drop the whole system in a low temp Non conductive oil.. just use a big fin heat die CPU. a pump to move the oil around the Tank. keep the dry Ice in a container with vent tube for the vapor, dunk it in the tank...... And my Science License says i have a PHD in liquid schwartz from the Ludicrous University--- P.S. Long Rectangle fish tank.. dry ice on one side. Pump on the other suck from bottom discharge topside towered Dry ice.. so you get whole convection loop.. system bottom middle of tank.

  • Easier way to do this whole experiment. Use air cooling in a walk-in freezer. Humidity should be lower and everything will be cooled. If condensation still occurs build a box for the computer and circulate the air in the box through desiccant chambers. Probably more resources than you have available but just a thought.

  • If you could put all condensation-prone bits into a nitrogen/CO2/argon/any* dry gas environment, half your problem would be solved. A glove box chamber (years ago I saw a couple at university auctions), media blaster chamber, etc. An old barrel might be made to work, if it's the blue plastic sort with the circular clamp locking down the lid. Place your rig, arrange and seal your feed-throughs (minor leakage is probably desirable), purge with dry gas, try it out. If you see condensation, purge some more. Or just keep the gas on while you run it, if you have a regulator and valves, instead of a couple of CO2 fire extinguishers. Though those might work fine, you don't want an over-pressure in something that wasn't designed for it. Because boom, and things flying around. *OK, maybe don't use arsine, arsenic pentaflouride, or similar.

  • I have quite the technological background, so here's a funny idea.. OR.. VODKA as coolant! :) on with the crap idea.. Take your £3000 CPU and remove the IHS if possible! Add a copper heat plate of your own, with Conductonaut-like thermal compound in between the core and new spreader, then the block. Ideally as others have said though, a custom block is likely needed.. You could always improvise, take a copper heatsink with fins far less dense than the coldplate, build a suitable housing around/on top of it to let you pass liquid through the fins instead of air and go from there, even without removing the IHS (guessing they are soldered anyway?) but..even that will take time and cost a lot. Plus i'm not sure soldering a custom cover onto a copper heatsink is viable due to...well, the solder? So i guess it would have to be milled from a solid block.. Hmm.. Unless you do some welding perhaps? Haha..

  • so if you built an enclosed fluid exchange unit... were the coolant could directly pass thru a condenser of an air conditioning system you would have no use for the dry ice... but eh, if someone were to do that... they would at least be using a 30'000-180'000 watt compressor unit and be cooling the boards at the high traffic hubs that switch some of the highest amounts of user/p2p data there fore making the internet work in the first place.

  • After watching this, I had a thought. So I went to the kitchen, opened the freezer. Got out the ice tray. Took 3cubes and placed them in a clear cylinder of glass I let them sit for about a minute for appropriate thermal transfer. I proceeded to get a chemical solution of C2H5OH and pour it over the ice. There is an instant display of heat transfer. I swirl the cubes in the glass for a bit more thermal transfer. I then add a bit of C30H32N8O10. Then I watched this video again. Great job guys. Great job.🥃

  • I don't have a "science license" but i DO have a systems administrator's degree and about 5 years of experience in QC for electronics design and manufacturing and so I can tell you with confidence that Yes, you ARE wasting your time. A thicker slab of metal would just increase the thermal barrier between the CPU die and the medium which is carrying away the heat, ending up as an insulator. If you wanna do something unique, build a refrigeration unit that liquefies and reuses Helium constantly instead of just dumping it in the atmosphere in bursts. That's the kind of stuff they use for quantum supercomputers up in Canada. They way they do it is by actually cascading several types of cooling to get as close to zero Kelvin as humanly possible. However, at those temps, your next worry will actually be keeping the capacitors on and around the CPU silicon PCB from freezing over and thus producing no more voltage. Depending on the motherboard that might be fixable with a very high performance thermal pad and a heat-gun pointed at the backside of the motherboard, keeping temps around 10 Celsius or slightly higher. Source: Look for "Typical Curves-Dissipation Factor vs. Temperature" in this datasheet about tantalum caps: www.farnell.com/datasheets/11903.pdf 10 to 15C is the sweeet-spot on the bell curve for low-charge (1uF)capacitors, while higher charge ones (100uF) seem to do better at @ 20C
