I haven't even used my DSI yet, but I have already fitted a cooling fan to aid in heat dissapation.
It was so simple I had to share the idea with all of you
Normally we try to make brackets to affix the fan to our imaging devices, or as I have seen done - plastic cable ties wrapped around the whole unit.
I came up with a quick and easy way to mount the fan, and it is removable in one second.
Look at the 2 pics below. Notice no visible mounting method.

It must be Magic!!!!!
