Nope, not comparing with phase change. Im comparing a normal a/c units full blast in 1 small room with those systems. Temps can be dropped significantly with the same setups. Not 15c but lower than without a/c. But there's a problem that would arise because hot + cold = condensation.

But still, to get an extreme watercooling set that can cool to 15 degrees celcius, how much money do u need to spend to build up that watercooling sytem?

Isn't it the same with getting a phase change cooling system?
Or, it might as well go higher than getting a complete phase change cooling system...

It might be...

The conclusion is, better get a phase change cooling system than spending you're money on extreme watercooling system liao...
