Dell PowerConnect fan question

Did you ever do the pin switch as shown in this video:

Nope. However, I just inherited a Dell 5424 that could use a fan
transplant. I might try it eventually, but not in the immediate
future. It's going into a mount top site where there's nobody to
complain about the noise.
The guy in the youtube comments says the KDE1204PKV3.MS.AR.GN w/ the pin swap works great.
Looks good. It took him a few tries to get the power polarity
correct. The open question is whether the fan sense wire wants a DC
level to represent fan speed, or if it generates pulses. I still
don't have an answer and suggest you use an oscilloscope on the sense
wire to see what it's doing (with the original noisy fans). I can do
it in about a week (I'm on vacation this week) or I might sneak into
the office for one day this week.
That pdf posted does not help decode these part numbers heh:
KDE1204PKV3.MS.AR.GN
vs
KDE1204PKV3.MS.AF.GN
Dunno. All I have to work with on decoding the part number was on my
previous posting.

Same thing. Just juggle the wires and it should work, assuming that
you got lucky with the sense wire.
