The two fans are held together by a custom made bracket which is painted in a nice cool blue colour. The whole unit is attached to your computer using the same screws which holds your AGP and PCI card in place. The bracket is very strong and holds the two fans very securely.
The fans are protected by metal grills, which is a very good idea. I would hate to see anyone, big or small, get their finger chopped off by a 2,400 RPM fan. The grills also give the unit a nice finished look.
Speaking of looks, The Card Cooler XT looks great. Everyone who saw it was blown away by the sheer size of the unit. If you want to add an in-expensive piece of equipment to your comp that will both cool it and impress the hell out of your friends, The Card Cooler XT will get the job done.
Power is provided to the two fans by ways of 4-pin pass though power connectors. The connector plugs into your power supply and having pass though power means you won't have to worry about not having enough power connector left to run anything else in your computer.
For those who like to keep track of how fast the fans are spinning, The Card Cooler XT is available in a 3-pin version. This version of The Card Cooler XT requires your motherboard to have at least two free fan headers. It may make for a cleaner install as well.
