That raised a red flag in my mind. What are you running that needs 1300 RPM and at temps are you at? With the system in my signature my RPM is 600 when idle and I get to max temp of less than 60 C at RPM well below 1000 (~800 I think).The fan that comes with the hyper 212 evo has been very loud in my experience (running at around 1300RPM).
