Axial−tech Fan DesignBetter, faster, stronger Originally developed for top-end ROG graphics cards, Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For TUF Gaming series PSUs, we've scaled that design to 135mm so it keeps things cool at low RPMs while producing less noise. | 0dB TechnologyQuiet intelligence An onboard controller brings the 135mm fan to a standstill when thermal design power (TDP) is below 30%, letting you enjoy light gaming in relative silence. Above 30% TDP, the fans automatically start up again. | Sleeved CablesSlim-fit Cables swathed in black sleeving leave your rig looking tactically clean. |
