eheim 1250 does not get hot, and it should be more flow than you need really. i had one with a waterblock and a chipset block, and the damn thing was flowing too hard for my Dubro reservoir, creating too much turbulence. took that out and put in a fill tube/hose.
the 1250 gets kind of warm, but definitely not hot. and mine runs 24/7, even with computer off.
