Hyper 212 EVO Noise

Recommended Posts

I have a new build about a month old now with a Hyper 212 EVO. I have been very pleased with the quiet operation until now. Recently the 212 has gotten much louder. It is only running at around 700 rpm. I know it is the 212 because I can increase the speed  of the two case fans and the 212 fan individually. Do I have a defective fan? Nothing has changed other than the increased noise from the 212. The cpu runs very cool.
