The fan runs a lot on mine, too.
It's been about 3 weeks since my last treatment with Tria and so far I've only got about 30% baldness on my armpits and about 50% baldness on my legs. My leg hair isn't very dark or thick, so I'm not terribly surprised. I am surprised that it isn't working better on my armpits.
My best results are on my bikini area. I got about 90% reduction where I used the highest setting. Just to see what would happen, I decided to try it on my entire crotch. The instructions tell you not to, so be careful. The closer I got to my most delicate skin, the more painful it became, so I lowered the setting. The lower setting didn't appear to do anything, so the next I think I'll try braving the highest setting.
I'd like to see reviews by some other people. *pokes*
