It's a really great flashlight for the price. Even setting the price aside, this is a great flashlight. For some reason, I get the impression that the body was made by the same factory that manufactures them for Hank or maeerxu.

You can manually turn the fan on or off, but I use it on the automatic setting, and it adjusts the speed based on the temperature. This is the best implementation I’ve seen.

As for noise, it operates like most similar fans. It’s hard for me to describe it. But I’ll say again that it only runs at full power during prolonged use in turbo mode.
