In the custom liquid cooled PC world, it is generally recognized as a bad idea to sandwich a radiator between two rows of fans. With most radiator designs, this actually creates a restriction of airflow as most radiator cooling fins are too tightly spaced for the fans to create a proper push-pull effect. Koolance recognized this problem and has designed three new radiators for its XC-Series that actually love being sandwiched between fans.
The new XC-Series Radiators come in three versions, the HX-120XC, HX-240XC, and HX-360XC, and feature a 2.1-inch thick copper core. They have a fin density of 30 fins-per-inch and are built around what is known as a Dual Pass design. This allows the use of high RPM fans in a push-pull configuration that actually increases airflow for added cooling ability.
The HX-120XC is a single radiator designed to fit a 120mm fan on each side, while the HX-240XC can fit two 120mm fans. Likewise, the HX-360XC can accommodate three 120mm fans on each side. MSRP is $49, $67, and $85 respectively.
