I have a Panaflo 120mm L1A and it's the best investment I've made in fans yet. I love it to death! Too bad my other one broke...LOL, it sucked a screwdriver into it. At least that's what
I believe happened.

I was moving stuff around my computer. Oh, I should first tell you that my case sits with the side panel off and my Panaflo(s) usually end up sitting outside of the case blowing in. Works quite well actually. Anyway, I had this one sitting out, and I was cleaning my room, and the next thing I know a screwdriver turned and moved forward, with the business end getting in the blades. It snapped off one of the blades. I was depressed for days...
Oh yeah, and I received that 60mm fan today...I'll test it shortly and tell you what I think.
