Fixed!

Some people have attempted to use refrigerators for various methods of PC cooling. In general, the fridge over-wears and the compressor motor burns out (or something like that.)

SAME CONCEPT. Salt water can be lower than 0*f without freezing, and has a higher thermal transfer rate than solid ice, so the beer gets cold faster.

For an accurate test, the temp probe would need to be driven into solid ice of the same temp as the ice in the saltwater.

Whew, okay. Thank you for the response.

TheSubtleKnife you could go regular ice but still use acetone like the DICE'ers use...

Slink This thread has gone on for long enough, ya? I'd say we've attacked the issue from enough angles. ;-P

The dice is outta the question for this kid. He is trying to use what he can. I just think that putting water in a CPU pot is a bad ****ing idea. Go with liquid cooling and the water chiller, and employ the use of ice and salt in the heat exchanger reservoir. (Salt should stay outside of the cooling lines, ya? Inside the cooling lines, there should be antifreeze coolant. I already said this earlier in the thread.)

Water condensation near your motherboard is still going to be a threat for you. Are you even reading this thread anymore? I'll PM you... ;-P

Any temperature change due to salt melting ice should be minimal (as with any phase change that lowers matter density should produce). Actually, ice is less dense than water (per volume), so this may not necessarily apply.

Whatever the case, salted ice turns to saltwater (which has a much faster heat transfer rate than solid ice) and at those "freezing temperatures", the cold saltwater would be ice without salt (obviously ).

EDIT: maybe I AM wrong? LINK

Oh wait "[adding salt] can bring the temperature down as low as -21°C" so no, I was right. I'm only ever wrong when I doubt myself. hahah jk
