UPGRADE YOUR SIMPLE 2-WIRE CASE FAN TO A 3-WIRE CONTROLLED-RPM FAN
3-wire fans with a built in RPM monitor aren’t so cost prohibitive
that you need to upgrade your 2-wire fans to save money, but this is a
really fun beginner project that lets you peek inside your computer.
Over at Hard-H20, a modding and hardware wiki, they share a well
documented tutorial for taking a 2-wire fan (which is just power +
ground) and upgrading it to a 3-wire fan (power + ground + tachometer).
By following along with the tutorial you’ll be able to take a simple
2-wire fan and upgrade it to a 3-wire fan capable of being
speed-controlled by the motherboard. In the process you’ll get to take
apart a fan and learn a little about how your computer and the cooling
system works.
