So no one's tried them?
The Panaflo's have a "Hydro Wave Bearing". Is this similar to the Rifle bearing?
I wouldn't mind the Antecs if they were quite. I'm thinking about getting a new PSU that has thermally controlled smart fans, and also fan-only power connectors to control case fans too. So normally loud fans wouldn't be a problem (unless it got real hot), but LED fans wouldn't be bright hooked up this way. I'd like to get get all new case fans that are quieter than my current Antec fans, and thought about the Panaflo L1A, though these Cooler Masters may do. I'm not sure about the specs of my Antec's though. Two of them came out of my Antec SX830, w/ a black and white label marked DF1208SL .20A, which are Top Motor sleeve bearing, but I can't find the specs for them (some DF1208SL are only .10A, making it more difficult). The other two I'm using came in the SX840 are have a blue and white sticker saying Antec w/ no other writing. They're louder than the Top Motor (probably ball bearing).
