Would Western Digital's reduced power spinup jumper feature lower rpm speed and temps? I have a mini PC and am seeing a little high for my liking temps on my WD Scorpio Black 7200rpm drive, and am wondering is this a feature I should use. (not worried about the side effects)

And what exactly does it do/not do.

First of all, the link you posted is broken. Here's the correct one:
http://www.wdc.com/wdproducts/library/other/2579-001116.pdf

The document does not mention reduced RPMs and this is understandable, given the fact that this reduced power spinup just limits the current the drive is using when spinning up.

  • How can it lower the voltage of the spin-up, if the RPM of the motor isn't reduced as well? In that case, why wouldn't the drive operate at the lower voltage all the time?

    @DemonCamber - There's no mention of "lower voltage" at all in relation to this RPS feature. You seem to interchange "current" with "voltage", which of course is wrong.
