You will finally learn how to install a CPU into a computer system, and what techniques are best for dispelling heat from within your PC tower. You will learn how to configure the TLC5940 and associated hardware, as well as basic operation from a software perspective. You will learn how to wire RGB LEDs, how to adapt common cathode or common anode LED depending on the application and hardware being used. In this project, you will learn how to properly solder and tin wire leads, how to create a secure wire harness with strain relief and a sleek, manageable appearance. Additionally, we can stack TLC5940's in parallel, easily allowing us to add more fans to hack and customize all of the fans in your computer! This is a really fun, simple, safe, and affordable weekend project. With the use of Texas Instruments' TLC5940 - a 16 channel PWM controller - and use of the finely crafted 5940 Arduino library - embedded design becomes extremely simplified for those of us more hardware inclined hobbyists. In this guide, I will be modifying my computer tower to remove large amounts heat generated by the high performance CPU and GPU, in style. Accent lighting creates a unique aura, customizing the object you are illuminating and creating a profoundly different perception. The applications of this hack are not only limited to 120mm cooling fans, but anything your creative mind can fabricate. In this Instructable, I will be guiding you through the process of hacking and converting a clear, 120mm PWM cooling fan used in common household PCs from a single color LED to individually addressable RGB LEDs.
