Xigmatek has been around for many years. They started out with CPU coolers and now have a wide range of products from coolers for just about everything to cases, power supplies, and their own line of thermal paste. Today we are looking at 3 of their CPU coolers, the Loki, Gaia, and Aegir. Xigmatek pulls their product names from mythology. Loki is from Norse mythology, mostly known for being a shape shifting trouble maker. Gaia is from Greek mythology, also known as Mother Earth. Aegir is again from Norse mythology is the god of the sea.
