I will never buy Scythe fans again. They still make their money off selling cheap fans with terrible sleeve bearings. There's no reason they should be selling sleeve bearings. I bought 5 a while back, and 3 of them were dead in 3 months. The other 2 were on their way out. Bought some Cougar Hydro Dynamic bearing fans, they've been rock solid for 18 months now, and they're quieter!
