Corsair 500R with H100 Cooling. Best configuration?

[GumbyTheBorg]

Hello everyone,

So I got a Corsair Carbide 500R case and a Corsair H100 water cooling system and was wondering what the best configuration for it is. Should I push air from the outside into the radiator or should I push air from the inside into the radiator? In other words, what's best:

Setup One (Push air from the inside going out)

Grill -----------------------------
Radiator ===================
Case ----------------------------
Fans ^^^^^^^^^^^^^^^^^^ (arrow is direction of air)

Setup Two (Push air from the outside going in)

Grill ----------------------------
Fans vvvvvvvvvvvvvvvvvvvvvvv (arrow is direction of air)
Case ---------------------------
Radiator ==================

Just wondering.

cheers,
