Akasa Viper are very good, but loud if ran at full whack. The Akasa Apache is quieter than the Viper but obviously doesnt cool as much.
To be honest, in terms of noise > performance, noctuas are very hard to match, let alone beat.
Yes the colour isnt to everyone's taste, but would you rather have something that cooled your components well, or something that looked better? Again, also depends on what you consider to be loud fans. I consider them to be relatively quiet at full speed, and almost perfect when ran via a fan controller to about 900rpm or so.
