Optimal fan set up for thor V2

[Nazy]

alright so i got a thor v2 and im getting ready to do a fan overhaul getting my new video card next week and next up is replacing all the stock fans in the case with better fans for optimal air flow the one thing im unsure of is a replacement 230mm front fan i am unsure of a 230mm that is worth picking up the rest of the fans im thinking some nf f12's should do the trick but the front fan can only be a 230mm so thats where im looking for more info on but i am open to opinions and recommendations on the rest of the 120mm fans also hope for some good ideas thrown my way.

The stock fans are more than adequate

if i was happy with adequate i would not have posted BUT i wanna go balls to the walls and i am over time upgrading everything so i can do some heavy OC on the CPU and GPU with a multi GPU set up when its all said and done so im going to need REALLY good airflow witch is why i am doing the fan upgrade
