Mr Black Cat Posted June 9, 2005 Posted June 9, 2005 My bad, I should've mentioned it in the original post. By the way, do you know what the best size holesaw bit that is good for 120mm holes? Good thing you said fan holes: Mr Black Cat Share this post Link to post Share on other sites More sharing options...
Mangar Posted June 9, 2005 Posted June 9, 2005 120mm = 4.7244 inches, so look for 4 3/4" Share this post Link to post Share on other sites More sharing options...
Bleeble Posted June 9, 2005 Posted June 9, 2005 120mm = 4.7244 inches, so look for 4 3/4" 489587[/snapback] I disagree. I suggest going slightly smaller than 120mm, instead of slightly larger. I don't know what sizes hole saws come in though. I know a few people have suggested 114mm diameter in other threads. Share this post Link to post Share on other sites More sharing options...

Bleeble Posted June 9, 2005 Posted June 9, 2005 (edited) Yeah, it might block airflow if you leave it at 114mm (or whatever). But, if you file the edges to make it smoother, it might decrease the size a bit. And I would like to point out that the 80/92/120 measure to the outside of the fan, not the blades. For example, the blades on my 80mm fan here are only 76-77mm. So, only a tiny amount of air would be blocked, if any. For reference: 4.5" = 114.3mm, 4.75" = 120.65mm. You would see the edge of hole on the outside of the fan with a 4.75" diameter cut. EDIT: Just to clarify, most fans are 80x80mm (or whatever size) squares Edited June 9, 2005 by Bleeble Share this post Link to post Share on other sites More sharing options...
Mangar Posted June 9, 2005 Posted June 9, 2005 Good point, what I did on a previous mod was to put some rubber edge around the cut hole to fill in a bit, it worked good. Share this post Link to post Share on other sites More sharing options...

If you're going to put rubber around the edge (I think it's a cool idea), then go with 4.75" Share this post Link to post Share on other sites More sharing options...
kobalt Posted June 10, 2005 Posted June 10, 2005 (edited) I,m with everyone suggesting a jigsaw with a blade having a ton of theet per inch, they're expensive to buy but if you have balls and dont have one you'll definitely need one again somewhere in your near future so might as well buy it now We never have enough tools. Sounds like a nice sig to me loll Edited June 10, 2005 by kobalt Share this post Link to post Share on other sites More sharing options...
