This is a question for all your machinists out there.

I've noticed that when I use my Novatac 120T for about 2-3 minutes, I can feel the bezel warm up. Based on the dissassembly pictures of the Novatac, the emitter module is snugly seated inside the body, so I'm guessing it's well heatsinked.

Now to the Lumapower M1, when I use it for hours and hours, it remains relatively cool to the touch, and not as hot as the Novatac. The emitter module is threaded into the body. I've heard that when two surfaces are threaded together, only about 20-30% of the surface areas are actually touching.

Do this mean my LP M1 is not as well heatsinked as my Novatac 120T?

Would coating the emitter module thread with arctic silver help heat transfer.
