Yes, it is possible . I recommend a low profile cooler something like the Noctua NH-L9x65, I would just replace the fan with the original one that has an RPM of 4000. [IMAGE]  
Hey everyone, is it possible to replace the smart cooling fan on the aurora r13 with another cooler, for example the bequiet pure rock slim 2 or will the bios throw an "cpu_fan not detected"-error like it does with many other aftermarket rear fans?
Aurora R13, CPU fan replaceable?
