Blowhole Guide

 

Here is the complete guide on how to make a blowhole using a Dremel:

Materials you will need:

  • PC case Case fan
  • Masking tape
  • Compass with pencil
  • Ruler
  • Dremel
  • Moulding
  • Mounting screws for the fan
  • Fan guard
  • Drill bits
  • Power tools (somewhat)

Step 1: Start by positioning your case fan on top of your PC case. Use a pencil to mark where you want to create the blowhole. Ensure you have the correct measurements. Before proceeding, make sure to remove all components from the PC case as metal filings can be harmful to the computer.

Step 2: Cover the top of your case with masking tape, specifically where you will make the blowhole.

Step 3: Place the fan on top of the case in the desired position.

Step 4: Trace the outline of the fan and mark the screw holes. Use a ruler to draw an X on the outline. The intersection of the lines represents the middle. Mark the middle with a large dot.

Step 5: Use a compass to draw a circle with the width of the fan blades. This circle should only encompass the area where the fan blades extend, not the entire fan unit.

Step 6: With the compass, place the end without the pencil on the marked X and draw the circle. This completes the outline of your fan.

Step 7: It's time to start cutting! Use your Dremel to cut along the marked circle. Take your time and try to be as accurate as possible, staying on the line. The time required for cutting will depend on your experience and the type of metal you are cutting.

Step 8: After completing the cut, take a break and drink something. Once you're ready, use sandpaper (300 grit and 600 grit wet/dry sandpaper) to smooth out the edges. Keep sanding until the edges are smooth and won't cause any cuts. Step

9: Check if the fan fits properly within the cut outline. If it doesn't match the length of the fan blades, you can use moulding to wrap around the cut. Take your time when cutting the moulding and ensure it fits properly. Patience is key here.

Step 10: Once you're satisfied with the mod, proceed to drill the screw holes. Double-check the holes by using your drill bit kit and the case fan guard. Use the appropriate size drill bit to match the screw holes of the fan guard.

Step 11: Drill the screw holes. If you have a grommet, you can use it to add a unique look and prevent fan vibrations. If you don't have one, plain screws can be used.

In the end, be patient and proud of your mod. You can purchase side door moulding for around $3.99 CAD at Canadian Tire, preferably the chrome-look type, which complements the silver Chenming case.

We hope this guide has made the modding process easy for you. With these steps, you can successfully create a blowhole in your PC case using a Dremel and enhance its cooling capabilities. Enjoy your customized and improved setup!
