If it were 38mm fans in a push/pull configuration you may see more of a difference, but with our setup (MB/CPU heatsink/case) that's not possible. I would opt for a powerful single fan instead.
Actually, if you try to mount push pull on our setup with my left to right orientation for the heatsink, u will soon find out the fan clips interfere too much with the NB heatsink to do. I'm forced to use a single loud 1900rpm 37db S-Flex 120x120x25mm fan.

The fan mounting mechanism is a bit different on the Mega Shadow, hence two fans mounting will work beautiful. Therefore 2x1200rpm 20db fans will give a similar CFM as a 1900rpm (as that's cumulative) but, run much quieter as loudness is a logarithmic scale (its not 20db + 20db = 40db). That, coupled with the Mega Shadow and its less restrictive airflow design (TRUE's need a good static pressure), will work perfectomondo.
