I do have a update to do to this thread.
Corsair have sent me two new 4pin PWM replacement fans, this should cure the noise issue being reported.
My SP120 PWM fans are getting fitted on friday to this cooler

.@stulid & Spook187: Be intrigued to hear where they fit in the range compared with the SP120 PWM High Performance Edition (ocuk link) and the SP120 PWM Quiet Edition (OcUK Link).
ahh sorry, its the The SP120 Quiet Edition PWM which i am fitting.
. Other than the Quiet Edition having a lower default speed, and the High Performance edition being able to go faster, I don't actually know what the difference is between the two if you were to spin them at the same speed! And then there's the one's included with the H100i, which are a third version of the SP120 PWM!Still be intrigued to hear your thoughts.
Odd maybe i know
