So I bought a twin pack of the SP120 Performance editions to try in my Arc Midi, and they seem to make a really bad humming noise that is really annoying and so much worse than the GT 1850s. 
I have them both hooked up to a fan controller and at any RPM the GT 1850s are quieter and also have a much nicer tone. Idling at 1000 RPM the Corsairs have a definite noise whereas the GTs are almost silent. Will be sticking with them in future
