Direct your 120mm and 140mm fan air to the exact point you need it. These grills rotate 360°°and the veins move 90°°up and down/side to side.

We use these to direct our fan air to the processor area, and experience shows that they will lower your temps by about 3° —5° Centigrade.

Simple installation as they screw on with the same screws used to mount the fans in the case. Four Mounting Screws are included with each grill
