The use of high-precision molds increases the heat dissipation area and improves the heat-absorbing capacity of the heat-absorbing bottom of the heat sink. The concave-convex heat-dissipating grooves and smooth air passages mean that the thermal resistance between the heat-absorbing bottom and the heating equipment is small, and the heat generated by it can be quickly absorbed. The aluminum alloy shell is treated with deep anodic oxidation and precise cutting, and the is sandblasted, which is exquisite and delicate, with great texture. Convection heat dissipation for fast heat dissipation. CNC finely crafted all-aluminum alloy heat sink with high-efficiency phase-change heat-conducting silicon chip, double-sided heat dissipation, effectively suppressing the increase in solid-state temperature and reducing SSD performance. The U-shaped frame screw fixing position adopts an adjustable design, no fear of the challenge of M.2 solid-state installation of single-sided and double-sided chips! Let the aluminum heat sink and the heat conduction silicon chip and the solid state drive fit more compactly!
