Yes it has a TEC. Are you saying that the TEC doesn't make the the aluminum block containing the laser diode and crsytal set cold? or are you just saying that it transfers the heat and that the heat still needs to find someplace to escape? usually that place is the air or a baseplate (most have built in fans). In either case I have ran CNI modules for hours without any noticeable heat build up to the shell of the module. The power supply is another story. I can guarantee you a good TEC does magically make cold. I have felt it with my own finger tips. Maybe magically isn't the right word but it sure seemed like it to me the first time I saw one.
