The only one 40x40mm I found has 22mm diode mount.... could not find any with 20mm diode mountNo, they are usually 40 mm on one side, so the fan is 1600 mm^2. Don't have a link at the moment, but they are not difficult to find. Just search for laser diode hosts. The modules are 20 mm in diameter and are cylindrical. The fans are +12 volts DC. You can get them for TO-5, 9mm diodes and TO-18, 5.6mm diodes. Those are the sizes of the NUBM44 and M140 respectively.
