Definitely not a redrand. On the XS thread they note it is built with a Z bearing which is a modified sleeve bearing similar to more convetional fans which according to their work is better at slow speed than double ball bearing fans.
In my own testing experience..I have noticed that too where the GTs do make a little bearing noise at slower speeds.
I feel pretty optimistic. There are a number of other fans with really quiet motors and bearings out there besides the GTs, so if these have a similar silent motor and bearing with simal GT style forward sweeping dense blades...could have another winner maybe even better.
I have always wondered what caused the harmonics issues we get with the GTs on some samples...maybe it is the ball bearings and a sleeve type bearing would avoid that.
I am just glad to see some competition and I REALLY hope they develop a 140mm variant next. They did say the start of a line of products..Edited by Martinm210 - 1/13/12 at 5:50am
