    Hey guys, thinking of replacing my GT 1850rpm on my 240 rad with some of the new Noctua PWM fans.

    Seeing as I will be controlling the speed based on the temp target, would it be worth getting 3000rpm fans over the 2000rpms?

    If the price is the same, may as well get the faster version if I ever need to use that sort of speed (and noise..)?

    do they produce more air volume tho? assuming they do then yer go for them, also when you say PWM, can you manually control them IE speed or is it done AUTO only, looked at their website and says its done via a PWM IC AUTO dont know the fans at all, but i used to sell ones before and even tho the RPM increased the air volume they out putted as not that much more, compared to the noise level increase.

    It's always law of diminishing.

    OP: the faster ones wont go as slow as the slower ones, up to you.

    As long as the minimum speed is the same, I see no problem.
    Asus boards have excellent software control of their PWM headers.
