Since downsizing from a 700d to a 650d I was forced to use a 140.2 rad.
Why? The 650 will take both 120 and 140 rad sizes? I doubt you are getting better performance from a 120.2 with decent fans on that 140.2 at least that has been my experience.

Heres a good comparative review: http://www.xtremesystems.org/forums...-Fan-Testing-on-a-HWlabs-SR1-Radiator-Round-7 which is summarised on Martins web site here
Heres my suggestion, don't get a 2x140 rad for the roof of the Corsair. Get a 2x120 rad and Scythe GT 1850's. The case has the holes for both and you will get much better performance from the 120 rad with the GT's

OP, would be interested in how your setup is performing for you? Is it as expected? If 1.38 works on a 30 FPI radiator I may well go for the Aerocools (1.07) on my target 8.5 FPI radiator, hopefully they would be as quiet as the 120mm versions.
