(9/10)
Ignore the curious colour scheme. This fan is whisper quiet whilst shifting large amounts of air at max revs. Fitted as an exhaust fan to an old Antec case and has helped manage a heat problem arising from a complete CPU/mobo/graphics upgrade. No need to change the case now!
Why 9 stars then? One of the anti-vibration rubber mountings tore during installation...and that was after a smear of silicon grease too!
