Jazakallah ! Kraken x52 is a great cooler so far , i have not seen my temps going beyond 55c in gaming load........ sometimes 60 for a brief moment .
As far as Asus Strix GTX 1080Ti is concerned . it is one hell of a beast at 4K gaming , all games are maxed out at 60 fps at 4K except Mass Effect ...... just a few settings are on high and not ultra ...... the game still look jaw dropping , i could do all out ultra but i prefer consistent fps .
