Hello, I have a total of 10 fans in my Cooler Master Storm Stryker. I have two SP120 fans on my Hyper 212 EVO in push/pull, two SP120 fans on top for exhaust, one SP140 fan at the rear for exhaust, 2 intake fans at the front, followed by a 200mm and 120mm fan to further push the intake air, and I also have one 120mm fan on the bottom as intake.
