I have connected the wrong poles

1

I have connected the wrong poles of the E40 laser
however, currently, the laser head is still working normally
Specifically, I have connected P - G - ttl to ttl - G - P
I want to ask if that will affect the quality of the laser head?Your laser is perfect for my purposes.

This will not damage your laser, the E40 has very good protection and very strong quality, and the 4pin input can be connected arbitrarily without damaging your laser.

E80 fan automatically spins when temperature is high right?
I did not turn on lightburn software but I did not remove USB connection and power source. I see laser is not working but laser fan spins and I forgot about it for quite a while (about more than 1 day) but I do not know if the fan spins regularly. Currently I see laser fan is still working normally but I do not know if that affects the durability of 2 laser fans
The weather is hot and the fan temperature is quite high
