recently built a new setup my specs are as folllows:
i7 3770k
Asus Maximus Gene v motherboard
Corsair h55 cooler
2-xfx r9 270x in crossfire
rm 750 power supply
8gb gskill 1600 mhz ram
74gb raptor drive
1tb wd black hdd
acer 120hz monitor

so my biggest question is how is everyone cooling these cases with crossfire setups? the cards sit literally right on top of each other. i ordered some cooler master 140mm fans for the front and 2 120mm exhaust fans from cooler master also. I am starting to wonder if they are going to keep this setup at reasonable temps. I dont really want to go crazy and put a custom water loop on this. So has anyone on here had experience with this and what have you done to keep it cool. currently with the stock 120mm in the back and the 140mm in the front i can game for about 15 minutes and the temps skyrocket to 103 c and i have to shut the game down and even at idle its idling at 60-65 c.

update: installed the 2 120mm exhaust fans and the two 140mm intakes. in furmark it lasts about 20 seconds before reaching 103 c. anyone have some suggestions here?
