750D Case Not sure how many fans is needed

Hey all, I'm building my first gaming computer and went for the 750D case. I'm just wondering if the fans supplied will be enough to cool down my system or if I will need to buy extras, and if so how many... System specs will be below:



Intel Core i7-4790K 4.0GHz Quad-Core Processor

ASUS Sabertooth Z97 Mark2 Motherboard

XFX Radeon R9 295X2 8GB Core Edition Video Card

EVGA 850W 80+ Gold Certified Fully-Modular ATX Power Supply

G.Skill Trident X Series 16GB (2 x 8GB) DDR3-2400 Memory



If you require more info please let me know



Thanks in advance :)
