I ordered MORSE brand 5.5″ size Hole Saw Attachment for installing 140mm fans (140mm = 5.51181″)

MV MORSE AV88 140mm hole saw attachment.

You will need a 1/2″ Hole Saw Arbor in order to use the 140mm hole saw attachment.

Attaching the 1/2″ Arbor.

You can use either a Power drill or Drill press. The Drill Press offers better precision and stability over using hand held Power Drill.

I’m using a 12″ Craftsman Bench top Drill Press Mfr. Model# 21914 for this guide. It retails for $214.99

Applying Masking Tape to the 140mm fan hole location on the access panel.

Place 2" thick or larger block of wood beneath the side panel, so you don't ruin your work surface.

You can download 140mm cooling fan template print out.

Using Center Punch to mark center of the hole, which helps pivot the drill bit in the Hole saw Arbor. Also mark the four fan screw mounting holes.

I'm using the Drill press with the 140mm hole saw attachment.

I'm using C-clamps, placed over pieces of plastic to prevent scratches on the panel and hold it in place.

Spray the cutting area with "Cutting Oil" or WD40 before cutting the hole, it reduces heat, so the hole saw blade will cut more efficiently.

The hole is cut, now use a rounded side hand file to clean up the jagged edge of the hole.

Using 1/4" size drill bit to make the fan screw mounting holes.

The 140mm cooling fan hole is now ready for installing PC Window U-channel rubber trim molding

I'm using these PC Fan vibration rubber grommets to help dampen vibration and silent the fan.

I use a Micro Flat head screw driver to install the Fan vibration rubber grommets.

The U-channel molding will cover any mistakes or scratches made while cutting the fan hole.

If you prefer to filter your fan, you have option to install this 140mm Modders Mesh fan grill.

I chose this 140mm wire fan grill to maximize airflow.


I've chosen this 140mm Apevia Blue LED Cooling Fan rated 50.28 CMF @ 21.1 dBA with LEDs that illuminate the entire fan and create a very amazing effect. It offers incredible cooling to increase the longevity and stability of the system and components. Each fan has seven UV-reactive blades and a black frame.


You can install the cooling fan as Intake or Exhaust, depending our your individual needs. You can use this guide to install the cooling fan as Intake in the floor of your chassis or in top panel of the case as an exhaust.
