I'm Building New Computer using the HAF-XB Case but i'm very confused about the best air flow. I Will be using a NZXT Kraken x60 on the front with two 140mm prolimatech alluminium vortex, 1 noctua 120mm NF-P12 at the back, 2 noctua NF-R8 80mm on bottom and 1 bitfenix spectre pro 200mm on top but i don't know if i should go back to front, front to back or front and back to top air flow. very confused.
