Forcing fresh air to your cooler is the most efficient way to increase cooling performance and reduce amp draw from your electrical system. This plenum fits perfectly to cover the intake side of your Quantum Cooler and allows much cooler air to be forced through the system via a 3 inch duct. A 175 cfm blower (minimum) should be used in conjunction with the plenum in order to cool properly.
Plenum attaches via extra strong double-stick tape, creating a seal to keep the cooler pressurized with the cool air. Forcing cool air all the way through the system and back out through the exhaust side of the cooler is the most efficient way to reach maximum cooling capabilities - no cool air is wasted and the system appreciates every bit of cool air it can get.
