[QUOTE="cwa107, post: 821206, member: 24098"] Because the fans are thermostatically controlled and there is logic built into the OS to kick them on at certain speeds and at certain thresholds. If the built-in management isn't working properly, there's a hardware problem (be it dust clogging vents or bearing wear inside the fan). So, forcing the fans at a static speed with a program like that essentially second-guesses the engineers that designed your equipment. If the machine isn't working within tolerances, this does nothing to ultimately correct that, it just masks it. And if you're using it just because you like to have the control, you're probably adding additional wear to the fans that wouldn't really be necessary without it. [/QUOTE]
