    The brand in this context doesnt matter. They use a variant of Maglev fans which where originally designed by Sunon and they still are built on that design (not all Macbook fans are made by Nidec, they got a couple of vendors). That is a whole different style of making those fanblade move compared to the usual brushless fan type for example. The sound characteristic is already different because of that. But the bynoises such as a whistle, click on start up and some high pitched frequencies are there because of how the fanspeeds itself are controlled with PWM frequencies. In that sense it will always be more noise within various fanspeed ranges.

    Sure PWM itself can cause some electronic noise but the problem is the high pitched/whiny fan noise caused by sloppy design choices of the fan acoustic/blades themselves.

    Macbook Pros get loud yes under loud but it's not a high pitched/annoying tone.. it's a deeper woosh sound, which is far less annoying.

    Agreed on the lower whoosh part - once I find somewhere with some Macbook/Nidec fans in stock I'll post some updates here.

    Again, pwm "whistle" has nothing to do with fanblades. Not to mention that they move about half the air.
