SUMMARY

This discussion focuses on modding a 200mm LED fan by replacing blue LEDs with tri-color LEDs and implementing a switch to control the LED colors. The proposed solution involves using a switch mounted in a PCI slot that connects to the LED loop, allowing for power distribution to each LED color anode in three stages. The user references a guide on electronics and LED fan wiring for additional insights on the modification process.

PREREQUISITES
  • Basic understanding of LED circuitry
  • Familiarity with soldering techniques
  • Knowledge of electrical switches and their configurations
  • Experience with PC hardware modifications
NEXT STEPS
  • Research how to wire tri-color LEDs for optimal performance
  • Learn about different types of electrical switches suitable for LED control
  • Explore guides on mounting switches in PCI slots
  • Investigate safety precautions when modifying PC hardware
USEFUL FOR

This discussion is beneficial for PC modders, electronics enthusiasts, and anyone interested in customizing LED lighting in computer systems.

I was wondering if anyone could help me with this.

I have a 200mm LED fan that currently has blue LEDs in it. I would like to swap them out for tri-color LEDs and run a switch through the LED loop to control which LED would turn on. I want to mount the switch into a PCI slot in the back of my pc. the switch would get power in from the LED loop and disperse power out in three stages, one for each LED color anode. the fourth stage would be off. anyone have an idea on how to approach a situation like this?
