I came across this link for a 7V Power Adapter for a 4-pin fan.
Product Link
Of course, they explain how it works and it is really easy to mod almost any four pin adapter to provide 7V instead of 12V. Basically, you just have to switch the position of the lead the fan uses.
Standard leads arangement:
5 G G 12 (incoming voltages/colors on the male adapter)
R B B Y
R B B Y (wire colors on the female adapter)

V V
Modified Leads on the female adapter:
5 G G 12
R B B Y

V V
By selecting the +12V and +5V leads, you get +7V. Thus, the fan will spin at a lower speed and, therefore, with less noise. Of course, this also lowers the CFM. But, I'm trying to get my computer a little quieter and this might be a good way to amke any old fan a lot quieter while still getting a "decent" flow out of it.
Anyway, I was just wondering if anyone has tried doing this and if it caused any problems.
