The issue here is that you need a lot of semi specialised equipment. You would be basically building an Air conditioner in or connected to your PC. The idea would be to have the R123 expand as it passes through the "blocks" connected to your CPU. I have included a partial parts list of what I know you will need. There will be much more. Also there is a better/colder option. R12 would use basically the same setup and be colder. One major thing to keep in mind when using any AC style system is that condensation both liquid and frost will be a NIGHTMARE so a high CFM CDA system will be required. Like a wind tunnel. 1. pump and something to drive it 2. condenser and fan system 3. receiver drier 4. expansion block 5. Tubing Having said all that. This would be a very expensive setup. A good auto grade ac compressor is $300.00+ if you are going to overclock test a lot of stuff then go for it. If not then it is not worth it.

This is an old thread. But the question is still valid and a lot has changed in auto coolant since its posting. This question is very relevant. This is not a accurate. While you are correct that it does prevent freezing and its name would make you think that this is its primary function. It's primary function is in fact to remove heat from the engine. Here is some information to help illustrate it. ""A typical vehicle with a four-cylinder engine cruising down the highway at 55 miles per hour will produce nearly 5,000 controlled explosions per minute inside the engine as the spark plugs ignite the air and fuel mixture in each of the cylinders. This is what propels the vehicle down the road. These explosions produce an extreme amount of heat and will destroy an engine in a matter of minutes if not controlled. The engine's cooling system is designed to control and regulate these high temperatures."" As far as Thickness/viscosity is highly dependant on ratio. however it will always be thicker than water. Corrosion is extremely important to consider if you want to use auto grade coolant. You have to stick to any 10 year rated OEM coolant. I recommend Mopar 10 year only because it is what I know since I work at a dealership. There are other compatibles. Avoid anything off brand, universal, 5 year or 3 year. Also there is no anti bacterial in auto anti freeze due to its operating conditions so adding an antimicrobial is going to be needed.
