Why is my vapor cold??

I don't get it. Just how low in the sub-ohm region do you have to get before the vapor actually becomes warm? I see so many people commenting on how hot their top caps get, so they use delrin insulators, etc.

Well, I've got a 0.7ohm dual coil set up, and when I blow the vapor on my hands it actually feels cool. Totally strange! I thought for sure the vapor would be warm.

Every vapor that comes out of my mouth when blowing is cold even with sub-ohm builds of 0.4 and under. The vapor from the atomizer is warm/hot, but when you blow it out it is cold.

You will never exhale warm vapor.

huh, crazy! i never knew that...ive also never had massive clouds like this before, so i guess i could never tell what temp the vapor was when i exhaled.

cloud chasing sure is fun..

You'll find that high VG will be cooler on the exhale since VG tends to have more moisture content than PG vapor. Might also be why VG tends to feel heavier on the inhale.
