But, if you plan on playing games without the risk of causing damage to your CPU, this cooler will do fine. Also, the height does not cause an issue with RAM clearance, and it will fit very well after installation.

For the installation, you’ll have access to an all-in-one mounting solution for LGA 1151. The “LGA 1151” is the CPU socket of i7 6700k, this means there is no issue or concern about whether it’ll fit. Still, this cooler performs very well for its design and budget, and it won’t let you down. Nonetheless, there is stiff competition from other coolers on our list, so Hyper 212 EVO got an 8 out of 10 in all our test categories; this includes performance, cooling quality, design and noise levels.
