In my testing I have seen a drop of as much as 5C switching a single fan setup from pull to push.
Mounting the rad against the back wall is not really an option unless you remove the fan switch(screws in any pcie bracket would likely interfere as well), but in the end there's so much cooling power in reserve that any loss of efficiency is really moot. I 've got it set for silent operation priority and I don't believe I've ever heard the fan ramp up even running Prime95 with 4K-8K in-place FFTs, after 20 minutes or so max temp 44C(dithering on 45) with mobo at 34C(just kept tracking 9-11C difference) with mild OC at 4.1GHz, fan running 875-925RPM.
