Introducing a new generation of performance PC radiators. The EX series combines the low profile design of our RS series radiators with the high performance of our award winning RX V1 series. This feat has been possible due to several manufacturing advances including, split fins, improved soldering techniques, and welded seam tubes. The EX series has been designed and optimised for low speed fans, so it can offer high performance cooling at very low noise levels. Supplied 30mm and 6mm 6-32 UNC screws.
