Cutting a fan grill

post #1 of 12
Thread Starter 
Whats the best way to cut a fan slot into the side panel of my antec 300?
Should i cut it out, and if i do what should i use for a clean cut?
Or can i just use my (mini) drillpress and cut a bunch of holes?

Also is there a site for patterns for fangrates that i cant print out and use for a guide?

What I did was go tape off the area I am going to put a fan, then took a pencil and traced out the hell (removed the fan from it for easier tracing)

Then traced the holes.

Next I use a razer blade to cut out the fan hole for my fan then used a dremel to cut it out.

After that used a file to make it smooth.

Finally drilled the screws holes.

1.Find template

3.drill center hole
4.cut with metal shears up to about .5in from the edge of the template mark.
5. Use grinder to slowly finish th last .5 in
6. Drill mount holes from template


Or use a dremel with A thin cutting wheel. The onl cut straight lines usually.

Ok, thanks. Do you know a good site for templates?
I also have a hole shaped drill bit for cutting those wire managment holes in desks, would that work?

What you need to do is to get a 120MM Fan Template, a 4.5" Hole-saw, Painting/Masking Tape, and a stable, area to work at. Plus to make the circle smooth, a file of some-sort.

Get the 120MM Template, after you laid down the Masking tape on where you want to cut. Measure the Diameter (4.5") Onto the Masking tape, and make a circle. After that is done, mark the holes for the fan bolts/rubber grommets.
When that is all said and done in sharpie, take your 4.5" hole saw w/ the drill, and mounting bit, and align the hole-saw to the circle that you traced onto the masking tape. Then, start cuttin'! When the hole is completely cut out, Drill the bolt/grommet holes. after that is done, file the 4.5" circle, then take a paper towel and go around the edges to find any spots you missed.
This part is optional - Get a 120MM Grill/Filter, And bolt it onto the outside of the case, to keep your fingers away from the blades (Once got my finger busted open from a 5500RPM 70MM Fan.) Now, Enjoy your work of art, and a cooler system!

Wow. You guys like to do things the hard way.

Use a drill and hole saw. You can get a template from mnpctech.com: http://www.mnpctech.com/Fan_Grill_Templates.html

First tape off the area you want to make a hole for the fan then square off and tape down the template.

Drill out the fan screw holes (I believe I used a 3/16" drill bit) and drill a pilot hole for the hole saw (in the center of the fan template). Then hit it with a hole saw. You should easily end up with this.

File the edges a bit with a curved metal file and dress it up with some u-channel and a grill.

Metal cutting hole saws can be a bit pricey. I spent about $30 for the hole saw and arbor (what the hole saw attaches to the drill with) at Home Depot to make an 80mm fan hole. But the results were well worth it. If your only going to make a hole or two its ok to go with a cheaper hole saw, just don't expect it to last long.

I would just use a high flow 80mm. Really there is not much a difference between 92 and 80.
