. I killed a set while reviewing them but thankfully OCZ saw the funny side and set me a nice new kit which at £350 a throw (and no longer available because of the stupidly low yield of the IC's - CAS7@2000mhz T1) I don't intend killing them again! If I could I would just go with the Noctua even though I hate the fan colours.Pretty sure the performance of the silver arrow is almost the same if you move the front fan to the back
