1) take in max and min temp
2) take in min fan speed in percent
3) read current temp
4) calculate percent of max temp
5) if below min fan speed percent set fan speed percent to min
    - otherwise set to percent calculated in 4

slope = (dutyCycleMax - newduty) / (tempmax - newtemp)
slope * (tempmax - newtemp) = (dutyCycleMax - newduty)
(slope * (tempmax - newtemp)) - dutyCycleMax = - newduty

- slope needs to be changed to a float otherwise we always lose the decimal point and might as well just make it 1
- I need a uint representation of the duty cycle to do math on I think, it shouldn't be as high as it's showing in the calculator equation
