Once you stick that on the CPU it shouldn't frost up anymore. If it does it won't frost so bad. If you stick a peltier on it definitely shouldn't frost. Your CPU will shure as hell be mighty chilly though.
Hey Geoff, I don't have to worry about shutting off the puter because the cooling system is completely seporate from the computer.
And as a bummer I am think about making another water block...better design. I am just hoping to get this 366 celeron down to 0 degrees F without a peltier. Every new thing I try out I get it a little colder. the last time I had it going it was down to 32F with Rain on and 42 with Rain off.
