I'm getting a lot people asking off list, Asking which size to buy for 140mm size cooling fans.

You can use a 5.5" size Hole Saw Attachment. (140mm = 5.51181")

Amazon has good selections for 5.5" "Bi-Metal" Hole Saw attachment for your Power drill, HERE

Other Hole saw attachment sizes

80mm = 3 hole saw
92mm = 3.5 hole saw
120mm = 4.5 hole saw
