The EX series from XSPC combines a low profile design with the high performance of our their award winning RX series. This feat has been possible due to several manufacturing advances such as split fins, improved soldering techniques, and welded seam tubes. The EX series has been designed and optimized for low speed fans, so it can offer high performance cooling at very low noise levels. This is a Cross Flow Radiator (1 port at top, one port at bottom). Compatible with 120mm Fans.
