Is it normal when

Is it normal when I plug in the 24v 2amp cable my laser module turns on with a red light and it sounds like a fan is on?

Anyone able to answer ? Thx

What laser? My Ortur II the lights on the circuit board light up blue I think. Then I press the power button and it turns red but the fan doesn’t come on until the laser is activated. And after the laser diode shuts down the fan keeps going for a while to cool it down.

Hello…. It is the JGT-LU2-4-SF24V
