Question about be quiet! Dark Rock PRO 3

Hi, it depends on the exact type of RAM you want. Max. According to BQ, the maximum height of the RAM is 39mm or 34.9mm to the fan. See: https://www.bequiet.com/admin...
Leave a few mm for the socket height of the RAM. The Vengeance RAM is available in various heights, and it also depends on which slots you want to use, whether the cooler can still be in the way. Also pay attention to the weight, it weighs a hefty 1197 g. This means that once you install it, you'll never move your PC again ;) (WaKü as an alternative) But it is a very good cooler.
