I am trying to put some fans on the inside of a hot-swap drive carriage, and there is a large open space that looks like it was made to hold 2 or 3 fans, but it is too narrow to hold a standard case fan (the fan is too high, or deep, however you want to call it). Every place I've looked only seems to carry 25mm ones. Are there any 80mm wide fans that are less than 25mm tall? Thanks!
