I cool my OC'd 8700k with a Corsair h100i v2. It has worked pretty well for about 7 months now, besides being an unwanted space heater in my tiny bedroom. I just have 1 question to anyone who can answer. In the Corsair Link software, there is an option to set the AiO pump to quiet or performance mode. in quiet mode the RPM is 1980 and very quiet. In performance mode the RPM is closer to 2940 and the pump makes an audible noise. I was just wondering which mode is optimal, and If it will harm the lifespan of the pump to leave it at this high speed at all times. Thank you.
