My son kept complaining about in certain games his PC would just shut down. Told him to monitor temps when playing and he reported back that the temps were going in the red. 6700k on stock cooler. Bought a mother ass cooler and now temps are running fine and no more shutdown. In the OP's case I tend to agree, but there is a use for big coolers.
Did he overclock his CPU? Did he install the stock cooler properly (thermal paste application and/or mounting)? Another problem might be the case's air flow.
Generally, for temperature issues, you only need an aftermarket cooler if you're overclocking.
