So my system is as follows:
CPU: AMD FX-6300 3.5GHz 6-Core Processor
Motherboard: ASRock 970 EXTREME3 ATX AM3/AM3+ DDR3 CrossFireX 2PCI-E16 2PCI-E1 2PCI SATA3 USB3.0 Motherboard
Memory: Corsair Vengeance Blue CMZ8GX3M2A1600C9B 8GB 2X4GB DDR3-1600 CL9-9-9-24 Dual Channel Memory Kit
Video Card: EVGA GeForce GTX760 w/ EVGA ACX COOLER2GB GDDR5 980MHZ 6008MHZ DVI-D/I HDMI DP SLI Graphics Card
Case: Zalman Z11 ATX Mid Tower Case Black 4X5.25 1X3.5 5X3.5INT No PS Front USB & Audio
Power Supply: XFX 550W 80 PLUS Bronze Certified ATX12V Power Supply


So I am about to install a cooler master hyper 212 evo to cool the CPU, but I only have the one fan that came with it and I currently cannot buy another one. So basically, will the cooler work with just the one fan and will I be able to overclock?
