Blue laser 74W NUBM35 Portabl?

[Borislav@87]

Today I installed a new active cooling with dimensions of 150/69/36mm with 2 fans. At 4A current, I can say that I am very satisfied with the result. It is very important for me that after stopping work, the temperature drops very quickly. With the front radiator, this was impossible.

Yep, we must keep the laser temp under control and I think with TEC we can overdrive these arrays.
