Can video card control a standard 120 MM case fan?

[KingFatty]

Hi guys,

I want to mount one (or two) case fans to my Accelero Twin Turbo, while still retaining the ability for them to be powered/controlled by the video card.

I expected to cut the wires and splice, but will the case fans put too much of a load on the video card (MSI 5850 reference)?

Is there an adapter that I could use, that would get auxiliary power from my power supply by a molex connector or something, but use the video card's fan connector to vary the fan speeds based on the video card's controller?

I'm thinking if something like this is available, but instead of getting input from the CPU fan pins, it's going to fit the video card's fan pins - is there something like this for video cards: http://www.frozencpu.com/products/10350/cab-183/Akasa_PWM_Splitter_-_Smart_Fan_Cable_AK-CB002.html

Years ago I used a fan controller with a dial on the front of the computer to control the after-market GPU fan, but now I want to automate this so I can just use a custom GPU fan profile with Afterburner or something.

Oh, maybe I need to use multiple connectors, such as the PWM Y-splitter above, and combine that with this adapter:

Now maybe I'm crazy, but this VGA adapter seems like it's just a simple splice? So couldn't I just splice the video card's pins directly to the PWM-Y cable, to get video card fan control, but boost the fan capacity because that PWM-Y cable uses auxiliary power?
