That's a good cooler, but still might arguably more than what's necessary for that processor. Even if you are overclocking it, something around the $30-$40 range might suffice, like maybe an Arctic Freezer 33 or one of the mid-range 120mm Be Quiet tower coolers. That Dark Rock 4 does have the potential to be a little bit quieter, though any of those units would be a lot more capable than the bundled Wraith Stealth that comes with the 2600. Under a typical gaming load, I suspect the GTX 1070 would be making more sound than the CPU cooler either way.
