Modding 120mm fan size.

Hi guys.

I've got some ideas for a case knocking around but i have no clue how big the circular hole but on a 120mm fan is and i really need to know. I got some templates of kong's site but cannot print them to size acuratlly because i have no clue with estimation. Has anyone got a good way of seeing how big the circle bit of a 120mm fan is?.

Thanks in advance.

sorry if the above doesnt make sense.

 

non surprisingly, about 115mm. It might vary a little from fan to fan though.

 

i remember reading somewhere that a cd is almost exactly the same size.

 

yep, true

 

i forget which site but they have fan templates you can download and cut out to help you. i printed off some and if i find them ill let you know

EDIT i found them, its www.moddin.net

 

I've used Moddin's 80mm, and found it to work nicely.

 

a 114mm holesaw is good for a bare edge, with trim, use a 120.
