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?

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

How much are you looking to spend?

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

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?

Doesn't hurt to try....

8 dba is a big difference.
