Does constantly changing fan speeds hurt its longevity?

[Guest]

Yo,

I have an ASUS P9X79 motherboard with the Q-Fan feature enabled but the "Standard" mode doesn't ramp up the CPU fan speed high enough to my liking when I put the CPU under heavy load, so I decided to change to profile to "Manual" instead, and set the values myself. The problem now is that even with something trivial, like opening a web browser, the CPU load, even though very short in duration, already makes the fan ramp up for a second or two, so it's basically going back and forth between low and high rpms constantly. Does this hurt the longevity of my fan?

You'll be fine. The longer it stays at Mac speed the shorter its life span. And visa versa. The fans are designed to go up and down with temperature changes. If it ramps up for a couple seconds but then goes back down its fine
