How many fans can I fit in this build?

[FLUDDzone]

Case: Cooler Master Cosmos II
Motherboard: Intel DZ77RE-75K Extreme Series Z77
CPU: Intel Core i7 3770K
CPU Cooler: Thermaltake Water 2.0 Extreme
Power Supply:Corsair AX1200i 1200 Watt 80 PLUS Platinum
SSD: OCZ Technology 256GB Vertex 4 (will add more SSD's as needed)
RAM:CORSAIR Dominator Platinum 16GB (2 x 8GB) DDR3 1866Hz x2
BluRay Drive: LG WH14NS40 (SATA)
Video Card: Galaxy GTX 680 SOC Windforce 5x Dual SLI
Sound Card: ASUS Xonar Essence STX PCI Express x1 4-pin

I plan on putting in as many fans I can fit and that my power supply can handle. Most will be LED 120mm fans. If I could, I would have 7 120mm LEDs, 5 120mm, and 2 140mm LEDs but knowing my power supply only has 12 4-pin connectors I have no idea if I can do that. I want to do a lot of overclocking with my CPU and GPU and I want to fit in as many fans possible because in the summer it can get to 90°F(32°C) in my room and I obviously do not want my computer running hot.(and maybe this computer could be a air conditioner too :lol

You have 4 fan headers available on motherboard.
You can buy adapter from molex to molex + fan header, and repeat it as many times as needed.

Normal 120mm fan draws about 2W. I don't know about led ones, but let it be 5W, and it's still less then 100W combined. Your PSU should be fine.

Thanks. Maybe I will add even more fans!
