I have mid tower H510 and I have NZXT Cam Beta version 4.32.5-b. In the Cooling part on the temperature graphs, I can set the temperature for the fan speed percentage. When my CPU temperature is around some point of the graph where I have fan percentage change, for example, I have fan speed 0% for a 40-celsius degree and 50% for a 50-celsius degree I have a lot of starts and stop fan because the CPU temperature varies from 38 to 42-celsius degree. Maybe is best to have a graph line for the start and a graph line to stop the fan. Then, I can set my Fan to go on 50% if the temperature drops to 30 Celsius degree and start if the CPU temperature is more than 50 Celsius degree. I think this is a good idea. Now I always listen start and stop of my fan every 2-3 seconds.
