Curious. How do you mounted a taller fan? Are the stock screws extra long so it can accommodate a centimeter taller fan?
The fan I bought has these rubber anti-vibration plugs that I used instead of screws on 3 of the holes. I will try to explain what I did. I didn't have to cut down my mounting posts at all with a 60mmx25mm fan..
1.) I used a piece of lexan about 3.5" x 3/5". I set the lexan in the very far corner where the center tab/lip is located and the back of the hood.
2.) I aligned one mounting hole in the hood with 1 mounting hole in the new fan. This if course will only work for one of the holes.
3.) I then marked the mounting post across from that point on the lexan.
4.) I then drew a 60mm circle based on mounting the new fan with the shared hole with the hood.
5.) You will then notice that the mark for the mounting post across from where the fan/lexan/mounting post will be attached is inside that circle.
6.) I drew a tab around that mark so I did not cut it out when cutting the circle out in the lexan.
7.) Cut the circle out without cutting where the 2nd mounting point to the hood would be.
8.) I then test fit the fan/lexan to the hood and marked the other 3 holes that need drilled to mount the lexan to the new 60mm fan.
9.) I then pushed the 3 rubber plugs through the lexan.
10.)I then mounted the lexan to the hood using a smaller screw. This is the hole that has the tab I didn't cut out when doing the circle.
11.) I pushed the plastic plugs through the fan and locked them in.
12.) Lastly I installed a screw in the hole that lines up the fan/lexan/ and the mounting tab in the hood.
I only used the .093 thick lexan and when I was done, the fan was no higher than that divider that is built into the hood.
