    Hey so, just need to ask if this will be possible.

    Here's a simple paint example before you start reading.
    http://oi44.tinypic.com/dlgbj5.jpg

    I have Leds connected to the Bitspower X-station then 4 pin molex to 3 pin converter coming out it's power and going into the fan controller's 3 pin connector.



    ( for your reference)
    http://www.frozencpu.com/products/7...n_Power_Extension_I_-_UV_LED_BP-XSP1M-UV.html - X station
    http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=34_82&products_id=608 - The 4 pin to 3 pin converter cable )

    I ultimately want to control all the LEDs plugged into the X-station by the fan controller.

    Can my 3 pin fan controller's plug power up the bitspower X station and all its leds?

    Are you planning on dimming the LEDs by using the fan controller? If so, the fan controller needs to output a PWM signal. LEDs don't work that way with "dimmer switch" (variable resistor) controllers.

    If your controller does PWM, you should be good to go.

    LOL, are you serious? Where did you pull that from? ANY fan controller will work, please dont make me pull the proof out.

    Please do pull the proof out that LED's will dim without PWM.

    Ive been using a Sunbeam Rheostat for years for fans and LED's and its not PWM... do you even know what PWM is? What kind of car do you drive? Id bet it had LED's instead of incandescent bulbs and uses a rheostat as well.

    Hey Vesko, it may help if you just post what fan controller your using :)

    I used a Lamptron FC2 to power a few led's and smled strips with great success

    Just because there is a little dial to adjust the brightness of lights in your car, does not mean that all the LEDs are wired into that dial! In your own words: "where did you pull that from?"

    The LEDs in a car Instrument Panel are driven via microcontrollers - so PWM control is easy and convenient. On the outside, car DRLs (Daytime Running Lights) have a noticeable flicker when filmed - another sign of PWM control. It's the way it's done.

    Actually the circuit does run through that in most cars. Besides, i debunked the myth that you NEED PWM.

    You did no such thing - I took the time to download the video, and all it shows is a strip of LEDs next to some microcontrollers...

    I did once use a variable resistor to control the LED backlight for a HD44780-style LCD. It had about three settings: Super Bright, Really Bright, and Off. So it wasn't much of a dimmer switch. PWM gives you control - anything else is just a kludge.

    LOL, no its not a microcontroller, its a Sunbeam Rheobus and its a 10K pot that controls it...
