There is a difference between quiet and silent, btw.
1000 RPM fans are quiet, but not silent.
I have 120mm fans that run at 2000+ and even that is not what I would qualify as loud.
I think that our two contrasting statements/opinions, illustrates the point that people perceive noise differently. But surely if someone wants a quiet unit then they want to reduce fan speed as much as possible, and truly quiet PSUs have much lower idle speeds than 1000RPM.
CoolerMaster GX 650W is also another solid candidate.
No it is not. I've seen reviews where the idle speed was shown as 1000 or 1100RPM.
