Cheap fan controller for Scythe S-Flex 1600RPM

I use 2 of these fans to cool down HTPC and receiver.
I noticed that spinning @ ~1600 RPM is quite noisy.

Now I was thinking of getting a 12v to 9v power lead but I think the fan controller is a wise option to go.

I don't need a fancy fan controller and I don't need a lcd display and so on.

Is there something that may suite my needs?

Has anyone tried to switch the S-Flex 1600 from 12v to 9v?

Thanks

  1. 3V really won't make your fans that much quieter. You're looking at around 4-6V.

    How much are you looking to spend?
  2. I think i need to give some background:

    My HTPC & reciever are stored in a closed drawers.
    I sit ~3M from the fans.

    @9v the s-flex produces 23 dba while @12v it produces 31dba according to silentpcreview.com

    Don't you think this would be the different?
    23 dba would be noticable considering my setup?

    I came across this nice 2 speed cable:

    What do you think?
  3. Doesn't hurt to try....

    8 dba is a big difference.
  4. It does hurt my pocket :)

    I guess the 9v would be the best option for silent/air flow.

    I was thinking of getting this one:

  7. Thanks but I don't want to hook anything to the MB and I have 2 fans I need to control.

    What do you think about this 3-fans controller:
