Capacitors and chokes pass demanding tests to achieve Military-grade Certification. Dual ball fan bearings can last up to twice as long as sleeve bearing designs. A protective PCB coating protects against moisture, dust, and extreme temperatures. An 80 Plus Gold Certification is the result of Japanese capacitors and other premium components. Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure.
