I think that 10 (W) Is the minimum to have fun, regarding the power i respect the rule that the laser maker wrote me when he sent the laser to my home.

At that time he spoke about a special plastic magnifying glass in front of diode, you can change It as a spare part in case but not so simple because It Is very small.

So i think that extra cooling can help, like you said, but i prefer not to test the glass life! 😂
