Same with my 7125, I keep plenty of free air around it. It warms up but doesn't get hot. When I first installed it the cat decided this nice warm spot was the perfect nap location. I bought a rectangle shaped wire holder (similar to this but rectangular instead of circular) from the dollar store and cut it up in to four pieces. The idea was to have big chunks with pointy bits sticking up so that they discouraged kitty from napping there. It works really well and since my amp doesn't vibrate, they don't move.
