Depends on a few factors, but in general push-pull setups aid to better performance.
In this test, Martinsliquidlab shows that the advantage the RS240 - the "basic" XSPC model - gets in push-pull over the RX360 in push is bigger than that of straight exchanging the RS240 to a RX360 (both in simple push), especially in med RPM - where most WC builders seek the sweet spot between silence and performance.
If "upgrading" to a RX over an RS is relative, then push-pull is just as much.
Also remember that the total thickness of the RS @ push-pull assembly (25mm fan - 35mm rad - 25mm fan) is 3mm less than the RX @ push (25mm fan + 63mm rad).
The AX is thicker @ 40mm, but in general, if an RX fits @ push, the RS/EX/AX should fit in push-pull, and perform better.
Ofc we should not forget that 3x additional fans might be a considerable expense, especially if we are talking premium fans like the Gentle Typhoons, but discussing absolute performance, push pull configs do help.Edited by pcfoo - 8/14/13 at 6:40pm
