Sorry...but I'm stepping out of this thread now...a SilenX is perfect for you

It's true.

The aircraft companies they could make a helicopter as quiet as the new Comanche is until they experimented with the main and tail rotor design. They don't use the same blade technology as you find in other helicopters from years ago and new ones today. Basically the point is the blade shape, size, and number of blades determines the noise level as well the air flow so it's not like this is anything new and unheard of, you just have to wake up and smell the coffee!

Correct, and with the bigger fan OEM's getting into advanced blade and motor designs hopefully we'll see a long overdue change in fan tech. I bought Noctua based specs and reviews and I haven't been disapointed. I just slapped in two Enermax "Magma" fans for top exhaust and feature\performance wise they're pretty cool too, detachable blades for ease of cleaning, bat wing blades and a very interesting motor.
