E5200 CPU Fan Loud(er)

[AudiR8]

Hi everyone i have noticed that my CPU fan has become loud, I think it is because i had OCed it to 3.4 ghz, but when i returned it to 2.5ghz the loud(er) sound was still there. I am saying louder because its not that loud, but it is loud enough to be annoying.


Is there anyway of fixing this? The CPU temp at the moment is 37 C its highest was around 60-70 C
