Evening all,
I have a custom built desktop with the following specs:
Intel i7 3930k @ 4.3Ghz
2x EVGA GTX 680 4GB GPUs
16GB DDR3 RAM
1x 250GB SSD
1x 2TB HDD
Cooler Master HAF-X case with after market fans
dual bay reservoir for liquid cooling
1x 360 GTX black ice large radiator (3x fans blowing, 3x fans sucking on either side)
1x 120 GTS black ice radiator
CD-ROM/burner/blu-ray
fan controller
plus a few other things
Anyways, my cpu and gpu's run a self built liquid cooled loop, under full load the cpu reaches about 40-50C and the gpu's about 30-40C. As mentioned above the larger radiator has six dedicated fans that blow/suck air through it for additional cooling.
To the point, earlier this evening I noticed the case's side fan wasn't working... so I took a few moments for troubleshooting and fixed it (faulty connector). During this time, I realized that all my case fans were sucking air into the case. Now, I understand general thermal dynamics and I understand that heat rises and cold falls, but considering that the larger portions of my hardware are liquid cooled... would I really see a dramatic change in temperatures if I were to swap the HAF-X's top fans to blow hot air out, and leave the lower fans to suck cold air in?

Basically since heat rises as you said, you want the intake to start low and the outtake to end high. You want air to intake from bottom to top as well. Here's my badly drawn diagram:
