How do you control fan speed manually on the Latitude e6430

As I have found from countless hours of searching for a fan controller for my e6430 laptop, there is no support and no solution. I find this a little disturbing. Making changes through fixed bios updates isn't enough. I need the ability to control the fan speed of my computer and so do many other people. Personally, I don't care about fan noise. I want a manual fan speed control and many other people do as well. How do we do it?
