Xigmatek rolled out second generations of two of its iconic mainstream CPU coolers, Gaia II and Loki II (pictured in that order). With its 120 mm PWM fan detached, the Gaia II measures 120(W) x 50(D) x 159(H) mm, and is a conventional aluminum fin tower heatsink, with three 8 mm-thick exposed copper heat-pipes tasked with drawing heat directly from the CPU, and transporting it to the aluminum fin stack. Weighin 460 g, the Gaia II is a mid-range heatsink. Its included 120 mm spinner can push up to 56.3 CFM of air, spinning at 800 to 1,500 RPM. Gaia II is designed to handle thermal loads as high as 150W. Moving on, Loki II is a compact tower-type CPU cooler for light thermal loads, as high as 130W. It features a dense aluminum fin stack to which heat directly drawn from the CPU is conducted by three 6 mm-thick exposed copper heat pipes. The heatsink is ventilated by a rare 92 mm PWM-controlled fan, which can push up to 52 CFM of air, spinning at speeds between 1,200 and 2,800 RPM. Measuring 92(W)x134(H)x50(D) mm without the fan, Loki II weighs about 330 g. Both coolers are designed to support the latest CPU socket types, including Intel LGA1150/LGA1155/LGA1156, LGA1366, AM3+/AM3, and FM2/FM1. Xigmatek didn't announce pricing, but we imagine the two Asgardians to replace their current-generation counterparts, at $30 and $25, respectively.
