I'm going to build a computer with an intel i5 4670k CPU and SLI dual Geforce GTX 650 ti boost GPU and i'll be overclocking. WIll the following cooling system be enough or will I need watercooling?
Cooling System:
2x Top 140mm TwoCool fans
2x Rear 120mm TwoCool red LED fans
3x front 120mm red LAD fans with speed control knobs
1x Side 120mm fan to cool graphics cards

Do ya wat do it air or water? What cpu cooler do u plan on this build?
What gfx cards? What case? You have lots of fans. Maybe fan controller is good to have.
That way u can adjust airflow better.

How much you have budget to this build? And what you need min / max?
Two GTX 650 Ti boost 2GB price is about + 300
One GTX 680 is not so much more..
