    I plan on getting a new PSU fan and I'd like to avoid
    doing any soldering, so I'm thinking about connecting
    it to the motherboard, but I'm worried about leaving
    the 2 pins on the PSU molex fan connector open and bare
    because I fear that eventually dust would accumulate
    and short the pins.

    Does that sound realistic? Any ideas on how to prevent
    this other than duct-taping the holes on a new molex
    connector and placing that molex on top of the pins as
    some kind of protective cap?

    The retail version of the Noiseblocker Ultra Silent S2
    fan is said to come with a PSU fan adapter. Can anyone
    confirm that this is indeed the kind of 3 to 2 pin
    adapter with a connector on the end that I could connect
    directly onto the 2 pin molex connector on the PSU?

    I'd be more than willing to pay a little extra for the
    retail version if that means I can connect the new S2
    directly to the PSU fan connector without having to do
    any soldering.

    Thanks in advance,

    You needn't be so paranoid. Dust that accumulates inside a power supply
    won't short the pins on a connector. If there were any danger of that
    happening, there several points of high voltage inside the PSU that would be
    emminently more susceptible to damage caused by dust.
    Unless it's wet, or if your PSU lives in a corrosive environment, there's
    nothing to worry about.

    You shouldn't worry about shorts caused by dust. But it would be
    uncouth to power the PSU fan from the motherboard. Soldering is not
    very dangerous or expensive, so give it a try. Or just use butt
    connectors, as others have recommended.
