The CoolJag Mini LED Flash fans are a great concept and look great with your custom message. The fans are made with a sturdy clear plastic, which makes them nearly invisible inside of your case - all you are able to see is the message with the brilliant blue border. The downfall of these fans, is the fact that they are unable to cool the system components as well as the stock fans that came with the ThermalTake Armor Extreme Edition. This is only a downfall if you are very concerned with the temperatures inside of your case, which most of us overclockers are.
