If the cool-ing performance is insufficient, please increase case ventilation orremove the L.N.A.Adding a second fanThe NH-U12DX i4 includes an extra set of fan clips and an extraset of thicker anti-vibration pads for installing a second NF-F12 fanin push/pull mode in order to further improve cooling performance.Please use the thicker anti-vibration pads on the rear NF-F12 fanfor improved acoustics if space allows. The y-cable supplied withthe retail NF-F12 fan can be used to control the speed of both fansvia the same mainboard fan header.1. Remove standard spacers on rear fan2.
