I'm deciding on which radiator/core to go with and just have a couple questions before making the decision. I'm going to be using two separate 120mm sized rads/cores, but want to keep it quiet too. So choices are down to BIP (maybe but I hear performance is not all that great), Dtek core, and of course Thermochill (I'd prefer not to break the bank though). So I guess my question is, will I get similar performance from a Dtek core w/ a low CFM fan like the Thermochill does or do heater cores require high CFM's like a BIX type rads? or is Thermochill really the only choice for low CFM cooling.
