Help selecting a fan

It's my first time building a PC. I'm using an AMD A10 6700 4.2 GHz 65W APU to save money, and the ASRock Socket FM2/AMD A75 FCH/DDR3/SATA3&USB3.0/A&V&GbE/MicroATX Motherboard FM2A75M-DGS. I'm also using the Fractal Design Core 1000 FD-CA-CORE-1000-USB3-BL Black Steel MicroATX Mid Tower Computer Case and the COOLER MASTER GX 450W RS450-ACAAD3-US 450W ATX12V v2.31 80 PLUS BRONZE Certified Active PFC Power Supply.

 I know the AMD 6700 comes with a cooling unit, and I don't plan on overclocking, but I want to know a good cooling unit for it. I just don't want it to catch on fire.

Stock is fine.

Stock should be fine in your case as elazar said, but here is a chance to win a free Hyper 212 Evo: https://teksyndicate.com/forum/buysaletrade/free-cooler-master-hyper-212-evo-wo-fan/154072
