I agree... the MCR320 and D-TEK FuZion is what I am using and the max temps I have seen is 47C at 4GHz.... A very good combo if that's the only thing in the loop.
I disagree. The 8800GTX dissipates around 200 watts?. That is significant, depending on the amount of overclocking. That Black Ice radiator isn't the most efficient radiator around.
I would change that waterblock to a D-TEK FuZion. My idle temp is around 27*C with a maximum temp of 47*C running Prime95 at 4GHz.
Also, it looks like you have that 8800GTX in the same loop. If that's the case, the 8800GTX is definitely driving that temp up. I have no idea by how much as I...
You didn't understand what I said....
Earlier models of the MCR-220 and MCR-320 used 3/8" fittings, and the new models use 1/4" fittings. I wasn't talking about different types of 1/4" threads. I have both types of MCR-220 radiators in my possession. One uses 3/8" and the other uses 1/4"...
