    Has anyone used these fans?

    Sharkoon Sys. Fan Power 120x120x25 @39dB(A) 81 cfm


    From here.

    I want to know if they are noisy at 7v, and if they will start up at 7v.

    A rating of 39dB@2400rpm is awfully loud for a fan with sleeve bearings.... Noise vs air delivery ain't that great either really, is it? Not a fan I'd have considered for a moment to be honest.

    Thats why I want to know what they are like at 7v.

    I need 3 x relatively cheap, moderately high cfm fans that undervolt well for a little project. Only catch is that they need to be all black.

    Roger that. Well, given they have sleeve bearings they should benefit more from undervolting than regular ball bearing fans in terms of noise reduction. Haven't used them so I can only speculate, but as a general rule that should certainly be the case.

    They look pretty similar to the Yate Loon D12SH-12 which people state is not particularly quiet when run at 7v or 5v.

    But the Yate Loon D12SM-12 supposedly isn't too bad when undervolted to 7v and believe it will go as low as 5v and is pretty much inaudible.

    somone pointed me at this site before but I dunno anything about them. Fans looked wuite good for the money/specs/quietness:

    http://www.dorothybradbury.co.uk/

    The two 120x25 fans:
    Silent 7V - 38cfm <16dB(A) 935rpm
    Low Noise 7V - 67cfm <27dB(A) 1635rpm

    The connector in the pic looks similar to the Panaflo/NMB fans - maybe made by them?

    Not sure if that's any help
