I'm using Intel stock cooler and 60hz monitor. When I set in-game frame rate to 120fps, my CPU cooler is louder than normal. Should I change my CPU cooler?
It is 'louder', because the fan speeds up.
Why does the fan speed up?
Because the CPU is doing more work
More work = more heat generated.
So the fan speeds up to remove more of that heat, keeping the CPU from melting into a pile of goo.
This happens with
every CPU cooler to some degree.
