The HEATKILLER® SW-X is a modular cooling system for mainboard voltage regulators. If combined with the modular HEATKILLER® NSB 3.0, it allows complete water-cooling of mainboards. Stock heat-sinks often work at their performance limits and lack sufficient reserves. Removal of the CPU-Fan in water-cooled systems further increases thermal problems. Therefore, temperature sensitive components should be integrated into the cooling loop, especially on high end mainboards. The increased cooling performance will guarantee stable operation even at maximum loads. All cooler parts are CNC-machined and completely made from copper (LT versions have tops made of black POM). Large cross section internal structures keep flow resistance low. The HEATKILLER® SW-X is modular and can be converted for use on different mainboards by simply swapping the baseplate. Separately sold kits allow the re-use of cooler-tops on new hardware. For easy selection of coolers, please look up your mainboard or one of similar design in the following compatibility list. compatibility list For some mainboards, complete sets with coolers for northbridge, southbridge and voltage regulators are on offer.
