Water Temperature to CPU Temperature - Page 2

post #11 of 22
Thread Starter 
I shall share, next weekend when the neoprene and dielectric grese come in from danger den, and then you shall get a full writeup with pictures


One question, I was thinking about using anti-freeze then I thought, if the water in my res is 6.1C and its going to get hotter with connection with the gpu and the cpu, I can expect the water in the res to raise somewhat. Why would I need anti-freeze unless its sub zero?

consider that water starts to freeze at about 4°C more or less. at 0°C it is completely frozen. this is called the titre temperature. the temperatur at which point the first flakes of solid start to form. also EG has a higher heat capacity and it will ensure that your liquid remains liquid within a bigger temperature range. its better to be safe than sorry.

Right but without my loop running its at 6C, so that will be the lowest it will ever be. If its going up, what would be the point of antifreeze? Because it will never get to 4c

i dont know what type of cooling u r using for the container but lets just assume that it overcools ur system due to any reason for instance control circuit failure. or maybe u shut down ur computer but fail to shut down the cooling for the container. what happens then? it is bound to freeze. but you should know better your system and its entirely up to you.

The lowest the container can possible go under ideal circumstances is 6.1C which it is running at now. There is no way to go colder.

ok i understand your contention. if thermodynamically the system cannot go lower than 6°C than you are probably safe. good luck mate.

antifreeze is used more as a corrosion inhibitor and algecide than for freeze protection. I only use 5% which would easily freeze.

sorry to say that u might be a little bit off on that point. antifreeze IS used as a corrosion inhibitor by way of additives but its primary usage is as an additive which reduces the melting point of water to below freezing point and conveniently also increase its boiling point to above the normal boiling point of water.

I know that, I am talking about computer use, I have been a mechanic for many years.
