If you're not overclocking and the build is not otherwise compromised, an aftermarket cooler serves no purpose.... it will outlast the PC's relevance. You're essentially buying a 1000 pound scale so your wife can check to see how fast she's losing her baby weight.
Yes, the Hyper 212 can be dangerous for novice users. Cooler effectiveness is based upon clamping pressure and TIM manufacturers will tell you the ideal is between 55 and 70 pounds. As there are no 'stops' on the mounting system, it's very easy to over tighten. This can result in physical cracking of the MoBo or just breaking of the embedded circuit traces within, without physically breaking the substrate that the circuits are embedded in. I have actually had the experience of "repairing" a unbootable system by unscrewing a hold down screw a half turn.
But, I also have had 3 users bring me a non working box w. Hyper 212's that we weren't so lucky. in two of the instances, we not only needed to replace the Mobo but also the CPU as 1156 MoBos were no longer available.... so a 1155 MoBo req'd a new 1155 compatible CPU.
