Controlling A tornado...

Need help.

My stuff is running @ 47c idle when i put my 92mm 118 cfm tornado fan @ 1/2 rpm (via fans only molex connector). I tried using the rheobus i purchased with the fan (this one ), but i have yet to figure it out and suspect it is not possible.

When i put the fan in a standard molex connector it is unbearable. Even while wearing headphones, with mp3's all the way up, and playing cs it's still droning in my ear. I'm looking to attain ~3,500 rpm. I figured i can deal with that much noise.

Does anyone know of something (both software, bios, and hardware wise) i can do to lower the rpm when i have it plugged into a standard molex 4 pin connector.

Progessively going deaf,
Al

*Note* I moved a sun on fan so it would suck air from the slk900 and shoot it towards my video card and my temps dropped to 41c idle, 42.5 playing mp3s, and 45c @ full load. Before this the fan was blowing air into the heatsink. Case door is on.

    Try running it at 7v maybe?

    usually the wires in the molex connector go:

    nothing - nothing - black - yellow
    (grnd) - (12v)

    change them to
    black - nothing - nothing - yellow
    (5v)
    (12v)

    Yeah, run it at 7v and it's fine. Anything lower than 7v and it shuts off.

    Aww... the tornado's not THAT loud... besides, after having it running @ full speed for a few months you should <strike>begin to go deaf</strike> start to get used to it :D

    You could try setting up your own rheobus with radio shack parts... or, you could just run it @ 7v...

    Its in norweigan but you can see the + and -. The molex is the one on the psu but it´s the same idea on the molex of the fan.

    using a very small flathead screwdriver, gently pop out the +5v, and ground (the one that goes to the fan) leads from the molex connector for the tornado. Put the ground in the +5v position, and the 5v in the ground's position, and you're done.
