Kool. One reason I like the Akasa Viper series is that they can push a ton of air at decent sound levels. So if your MB has proper fan speed management, you can dial down the Viper's RPM to "average fan" levels, where it will generate less then "average fan" noise levels.
Side Note: I do not recommend using any high end fan on Corsair AIO coolers having integrated fan controllers. From personal experience, if the controller goes bad, it will take the fans with it. Lost 2 Viper 140s that way...
