Today we test two new CPU cooling fans for Intel's latest LGA 1366 socket, as well as the previous LGA 775 and AMD's k8/AM2. Glacialtech offers the UFO V51 and Titan the Fenrir (TTC-NK85TZ). Both CPU cooling solutions promise to increase the overclocking margins of the latest CPUs offering power users some extra performance.
