Has anyone ever tried putting a peltier between a filled Ln pot and CPU to see if it cools more effectively?

I dont think it could work, but i cant find any evidence on the net to suggest that it wouldnt.

ideas!

Wouldn't it just work as cascade phase?

the point of a pelt is to have decent cooling on a relatively 24/7 period of time. DI/LN2 won't last that long unless you want to spend lots of money.

the point of DI/LN2 is to do benches for a short period of time, whereas you can overclock a pelt and have it overclocked awhile...

cascade phase is totally different. its phase change systems built on each other to help each other cool down to extremely low temps. like a condensor on top of another condensor w/ multiple refridgerants in it.

Im meaning in a short time scale, as a coolnig experiment, as the name of this section would suggest, thus it wouldnt be a lnog erm soution. Obv I know Dice and Ln arent suitable for everyday use!!!

well the thing is it's not going to cool your pelt down any more than lets say water. the only reason water is there on a pelt is to remove the extreme amount of heat that the beast creates.

if you have dice or ln2 you might as well have the cans to do some extreme benches.

So super cooling the hot side wont make the cold side any colder?

That's the way cascade works, but it appears it doesn't.

You initially said Cascade Phase. Phase change cooling uses a refrigerant pumped around a loop and goes through a boiling/condensation cycle to achieve maximum heat transfer by maximising the thermal coefficient of a given medium. Cascade, as you have now put it, is using one cooling method to cool another cooling method, thus creating a "cascade" of cooler, with one cooling the component, another cooling this cooling device, and so on.

cascade is different though because it uses refridgerants to cool each other down. putting dice on a pelt i would have to assume it wouldn't do much to it.

Wouldnt work. Pelt's are made to operate at a certain wattage only removing the wattage its meant to use. It would probably act more as an insulator and get worse temps

No. cascade is a general term. It is phase change which uses refrigerant. A "Cascade Phase Change" uses two or more Phase change units. One cools the hot part of the other Phase Change unit that cools the CPU.

Ive jsut read that the thermal difference between the 2 sides of the peltier decreases as the temperature of the hot side decreases. This makes me sad in my quest to achieve absolute zero

cascade works by first condensing a gas at room temperature. There are many choices as to which gas can be used, and essentially, any gas that can be condensed at room temperature at a reasonable pressure could be used.

The condensed gas then evaporates in the "heat exchanger". Now, all that is handled by the first compressor. The second compressor is charged with a different gas, generally one that cannot be condensed at room temperature. This gas is selected based on a number of factors, but generally a gas with a boiling point between -80C and -110C is used, since it is usually possible to condense gasses in that range with moderate pressures around -20C to -40C.

The second stage gas goes through the heat exchanger as well, where it is condensed by the cold environment created by the evaporation of the first stage gas. Then the condensed second stage refrigerant moves on to the "evap" of the system, which is what sits on top of the CPU.

I know, but the reason its called a cascade system is because you are simply using multiple coolers to cool more efficiently. You are cooling the hot section of one phase changer to achieve an even lower temperature at the cool side. What nobodies getting here is that cascade does not mean a phase change system! Its a general term to describe 2 or more coolers operating together, with one cooler cooling another cooler...if that makes sense.

Its the incorrect use and definition of the word!!!!

Cascade simply means to overlap!!! It is the "Phase Change" phrase which describes the cooling method!!! Ok, maybe cascade phase change cooling is shortened to cascade, but this is in the context of phase change. Out with this context, it simply means overlapping.

slow down there turbo. now cascade may be a universal term, but you're on OCN where it means a big ass phase change cooler
