Enermax TC-8CAS-BL 4 LED Case Fan
 

The fan looks good and the blue colour does light up any system well. The fans are very powerful and can shift airflow whilst remaining quiet effortlessly. Price wise I think they are good value for money and would highly recommend them.

In future versions I would like to see the ability to alter the brightness of the LEDs purely so that all customers could alter them to meet their own preferences rather than the current one for all setting.
