FanControl

Prelude

When I bought my antec P180 pc tower, it came with its own fan control, a simple one, a switch that changes the supply to the fan to 12 / 7 or 5Vdc. As it so happens, I enjoy a noise-free pc, the fans run at 5Vdc. No problem. UNTILL, they got worn, dirty, br0ken ect, they now can run at 5Vdc, but can not start up, a common problem with 12Vdc Fans and ppl that try to run them at 5Vdc.. After about 2-3months of switching them to 7V and back to 5V when booting the pc, I decided that it was time for a fan control.

2 things to consider when wanting a fan control in the pc:

• What kind of control? Linear or PWM ?
• How to mount it without damage to the cabinet yet still possible to reach it to adjust speed on those warm summer days.

First: PWM, inspired by the work of mhl's fancontrol and that of Giorgos Lazaridis(PCBHeaven)
