80mm blowhole?

[rack04]

When using a holesaw to cut a blowhole is there a certain side to start the cut? I have never used a holesaw before and don't know if either side will burr. Thanks.

You should start from the side that is on the inside of the case so if the holesaw jiggles a little bit you won't be able to see the mark. But you should also cover the area with a masking tape.

What size are the screws that typically come with 80mm fans? I am assuming 1/4" but I would like another opinion on which drill bit to use?

[Transnone13]

Looks like it. Measure them to doublecheck.

Use this for a guide.

i did mine from the inside

just put painters tape on both sides it will help you from scratching the paint

or use that light brown tape (cant rember the real name)

Masking

I have read somewhere that it is wise to use some sort of cutting oil when making this cut, is this really necessary?

[Transnone13]

IS this steal or aluminum? And it wouldn't hurt. When I cut/drill I just used cooking oil. Worked for me.

[rack04]

The case is aluminum.

[Transnone13]

YOu should have no problems then; nice and soft. If you feel to the need to use oil, dont worry you dont need it really.

You are correct, but it is real hard to find a 3.1496063" hole saw

[Transnone13]

Lol, you could drill the hole and touch it up with a drum sander on a dremel.

what size is it for 120mm then??

[Transnone13]

4.5" i think. I used a cd as a template. You can use mini-cds for 80mm fans.

no never ive cut my aluminum and steel cases without oil

you use oil if the bit is going to get hot and a case is very thin no matter what material you should never need oil for cutting your case
