Well Like I Said, Vaporization of a Liquid does draws a massive amount of energy so it is possible for it to cool down a system with relative ease, (edit: I was rushing and just to clarify, after 80°C isopropyl takes in even more energy for a phase shift, so in theory it would be extremely dificult for the loop to reach any temp above 80)but like also said, Dealing with gasses inside a cooling chamber is a whole pickle on it's own right, a vapor chamber esque approach could work,with the proper seals in place. Thanks for reminding me about that, completely forgot about that, The heat transfer coefficient does take a MASSIVE hit from the increased viscosity, it would transfer heat at a lower rate than water, 3.75 times slower in that case, one redeeming quality I Can think of in this case is that the thermal diffusion coefficient of MO is roughly the same as water, since doing math based in pure theory won't account for the discrepancies in everyday fluids, so the main problem in this cooling solution is time, so after you crashed my little party of forgetfulness I would take only a few upsides from this: 1- If it spills from a leak you don't have to worry about him frying everything in sight 2- Mineral oil isin't a fluid any kind of life would want to live in, so you can drop and forget (with the right seals and O-rings) 3- MO is slightly basic, so it means that it will not damage any metal parts inside the loop, I'm looking at you H3O 4- All oils retain only a small amount of gas inside they SHOULD cause less random bubbles 5- MO will have to run at a lower speed so less noise?(JK) Feel free to correct me on this, my last class in thermo was years ago. PS.: About cleaning the loop aftewards, it's a nightmare I know, but think of the braggin rights

Hello lads, A thought crossed my mind, What if I put Mineral oil inside a closed loop system, and frankly what I've found out on some older posts that my necromancy skill didn't allow me to resurrect, was astonishingly miss informed, I currently have an AIO, my system barely needs even that amount of cooling, so with some key points I'd like to point out, I'd like to discuss with some crazies that done/ want to do, some more unusual liquid cooling solutions. First things first let's dive down to some numbers: Specific heat of water is around 1 kcal/kg, and its viscosity is around 1 cP@20ºC, but let's be more realistic and place it at 0.9cP@40ºC, the idle temp of most loops. The specific heat of Mineral oil is around 0.4 kcal/kg, so it transfers heat at more than double the speed of water, so that fluffer that keeps saying in every single forum that I've visited that mineral oil is an insulating liquid can go plow a troll, it's viscosity is around 44cP@20ºC or ~15cP@40ºC, so it would require a larger than average pump to maintain a steady flow, but before you scream that at a minimum it's 15 times the viscosity, I'll say it now, NO you don't need 15 pumps worth to pull that liquid a single D5 per block SHOULD be ok. Next and for now last is 99% isopropyl alcohol With a specific heat of 0,6 kcal/kg, a viscosity of ~2cP@20ºc or ~1.6cP@40ºC, this is the fun part, Isopropanol has a boiling point of 80ºC@1atm, so theoretically he should vaporize with a random AMD'esque spike, pulling even more heat with his latent energy and even more heat if he becomes a gas since his specific heat is even smaller when in gas form, but there are many problems with isopropanol, main one being that he tends to vaporize in ambient temperature something that requires a whole post just how to deal with that. But now for the elephant in the room, that I haven't addressed, seals and o-rings, in short, I'll make a general rule for exotic liquids: EPDM (the usual run of the mill rubber seal): Water, acids and Ketones, grade A, against every other compound, DON'T TRY IT. NBR: A monster of a rubber, he's resistant against most forms of chemical attack, and he's made for oil like substances, just get ketones away from him. Some other words of advice, All acids will corrode all metal parts in the loop, and mineral oil will break apart PETG, Acrylic is fine for mineral oil, but I wouldn't recommend it for Isopropyl, it tends to stain and bloat, if you truly want a mad scientist closed loop I'd recommend glass tubing. The main thing I'd wanted to clear up was those god-awful "facts" about the properties of mineral oil, But do feel free to post crazy cooling solutions like vodka, or orange juice cooling.
