So Swiftech is getting a new radiator? I'd say it's about time... Not too surprising what with the radiator box that Swiftech just put out.
At 50CFM it seems that the Big Momma heater core is superior to the 120.2 by 30W... However, the 120.2 has places for 2 fans... So I should double the CFM for the 120.2 to 100 CFM or 2.8M^3/minute so the heat dissipated is, in fact, about 320W.
Is he asking for data from you? Or just a
link?
Anyway, the double heater core is about 1.6... times the size of the singe radiator so it'd be about 420W with two equal fans, I think. This is with fans that offer 50CFM at 0.05" H2O or 12 Pascals, or a weak 120 in other words (about 30-35DBa)
