Nope. They'll just spin a little faster. Or you can turn down the intakes. My front intakes generally run @ 540rpm (as low as they go) unless I'm into a heavy game, then they'll ramp up to @800rpm tops. Aio fans run at @600rpm idle and gaming @900rpm. Neither ever run at max, even under stress loads. Gpu fans are so good they don't turn on till the gpu hits @65°C and hit @70% speed at 80°C which only ever happens under stress testing.
Between the overwhelming cooling ability of a 280mm rad with good 140mm fans, 2x good 140mm fans in front intake and the thermal efficiency of the newer intel/gpus chipsets, its getting to the point where it's getting almost impossible to overheat a decent case airflow. You are much more likely to hit...
