I had to remove an exhaust fan on my Side panel when I upgraded to a new CPU cooler. The cooler is a Thermaltake Contact 29 with duel 120MM aftermarket fans from thermaltake. So when I did what I did the system started to run a little warm but not overheating. So I am trying to figure out what tools or items I need to make a 120MM fan hole in the top om my Enermax Staray case so it may exhaust the heat better since I now only have one exhaust fan in the back of the case now due to the size of the new CPU cooler. So what would I need to add a fan to my Case. Any and all help would be a big help. Also I will put pics of my case below and the ling to my case to so yall have an idea of what is looks like.
