1.quality construction 2.With the patented Heat Pipe Direct Touch technology, the heat pipes lie directly on the CPU. The advantage compared to a base plate is the faster heat transfer without additional resistance. The thermal conductive coating is a thin protective layer that prevents oxidation without affecting heat transfer. 3.With the patented Heat Pipe Direct Touch technology, Heatpipes are located directly on the CPU. The advantage over a base plate is the fastest heat transmission without additional strength. Thermal Conductive Coating is a thin protective layer that prevents oxidation without compromising heat transmission. 4.The ETST50 AXE ARGB is equipped with a 12 cm pressure fan, optimised for use with CPU sinks. Patented Twister bearing technology ensures quiet operation and a long service life of up to 160,000 hours MTBF. The 9 pressure fans operate with a wide speed range of 500 1,600 rpm for extremely quiet operation and cooling power. 5.ETST50 AXE ARGB is equipped with a 12cm pressure fan optimized for use on CPU coolers.
