I have a similar fan, mine is 24 V, but about the same size. I just made a support for it with toothpicks and glue gun, and put it on top of my monitor to get the heat away from it... I tried to use it in my case, but than I got a better 115V fan (the one that they use in coolers for the pop in pizza places), and now I'm happy with both things. The monitor is one of the most important things, so I decided to protect it
