If you have a good case, you DO NOT need an aftermarket cooler! I even overclocked my 8320 with stock cooler to 3.9GHz and 4.2 turbo with 1.28v (lower than default). With a 30 mins stress test, CPU temp never got over 55°C (room temp 23°C) and north bridge max 59°C . BUT this is with a good airflow in my Antec 300 case with 2 120mm and 1 140mm fans (all on low).
It's a disgrace a mod is just guiding ppl to buy stuff that is not necessary...
