Question about Intel Core i5-8600K

Which cooler should I use for this processor if I plan to overclock? I wanted to take the be quiet! Pure Rock (15.50cm) but that could be tight. So for operation without OC this should surely be enough, right? The processor's power loss without OC is already just under 100 watts and the be quiet! Pure Rock (15.50cm) only dissipates 150 watts. Should fit with the MSI Z390 A Pro board (voltage regulator, ram etc..). MfG
