This is Logisys Computer's Thermal Cooling Venting kit. It's the best and most economical and effective way to cool your PC because it simply takes out the hot air directly from the heat source inside the computer, instead of letting the hot air flow around and stay in the case. Alternatively it can duct cool outside-case air directly to the heat source dropping temps lower than when being cooled by warm inside-case air.

This kit comes with a 50 mm long thermal hood, two attached adapters to fit in any 80 mm or 90 mm fans, additional detached adapters to fit in any 70 mm, 80 mm and 90 mm fans, an 80 mm fan filter and screws to fit most applications.
