CPU coolers are not on the recommendations because too much depends on the case and the owners ability/desire to overclock and how far he/she pushes it. The heavier the OC, the better the cooler has to be, yes?
So, OEM fan will work for non-OC and daily usage of office apps, mail, web browsing, etc. If you are into gaming heavily and will be taxing the CPU to the limit in your game, you might want to add Coolermaster Hyper 212 or a Noctua NH-12P or a Scythe Ninja. Or you could also go with one of the liquid cooler solutions if the radiator will fit your case.
Do your homework and make sure the mounting supports the motherboard socket and the unit will fit the area around the CPU, clearing the top of the RAM and missing the GPU in the first slot. These problem areas are what makes the difference in your choice of CPU cooler.
