The HEATKILLER® NSB 3.0 series combines performance and maximum compatibility. The Mainboard waterblock is designed to ensure compatibility to many Mainboards. The mount is very flexible to adapt to virtually all applications. The waterblock is shipped with two mounts! This allows mounting on Mainboards with a diagonal hole spacing of 43,0 to 79,2mm. The orientation of the whole is irrelevant as the waterblock can be rotated against the mount! The cooling plate is made from highly pure electrolytic copper and has a very efficient cooling structure which also allows a very low flow resistance. Despite the compact dimensions (39x39mm) the connection threads (G1/4″) have a spacing of 22mm. The top plate is made from high-quality POM, the mounts and inlays are made from brushed stainless steel. The HEATKILLER® NSB 3.0 can be mounted on either Southbridge or Northbridge.
