PSU Fan Replacement w/o Soldering

[Will G. S.]

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.

Time is what keeps everything from happening all at once.

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.

not all PSUs use any kind of plug in connector for
the fan.

Mine has a connector, but I realize that there are PSUs
with the fan wires soldered onto the PCB.

you could just disconnect the wires for the PSU at
the fan and splice them to the wires on the new fan.
that's what i did when i replaced the fan in my
Fortron FSP400-60PFN with a Panaflo M1A using 3M
Scotchlok UY connectors.

I'm waiting for someone to tell me that there is a
3 to 2 pin molex adapter I can use instead of having
to splice the wires, but my backup plan was to use a
pair of aluminum crimp splicers and slip a pair of
heat shrink wraps over them. Duct-tape would do the
job, but I want everything to be as clean and elegant
as possible.

Thanks for the idea about Scotchlok UY connectors,
I might use them if I find them locally, they seem
like a great alternative to classic wire nuts.

You're probably right, I'm just a bit worried about
this particular connector staying open because, unlike
other potential problem areas, here the pins are not
only very close together, but also happen to be in the
middle of a box shaped piece of plastic, which makes it
ideally suited to collecting dust. I guess as long as I
don't get a laser printer or a photocopier there should
be no problem, but the so called modern systems leave a
lot to be desired and not just in terms of safety.

Any info on 3 to 2 pin molex adapters?

Thank you all for your input,
