PC Case Mod Changes Lighting Based on Case Temperature

There are plenty of software-based temperature monitoring solutions, fewer hardware-based solutions, and even fewer hardware solutions that include prominent visual indicators. This DIY hack changes the lighting on your case for at-a-glance temperature checking.

Taylor upgraded his hardware and, as a result of the beefier hardware, had a variety of heat-related issues. In order to provide immediate visual feedback on the state of his computer, he cobbled together a temp checking system that toggles an RGB LED behind the front grill of his computer from blue to red based on the internal case temperature.

While we like his initial build, we think that disabling the LEDs in the fan and having the only case light come from a series of LEDs that toggle between blue and red would be an even better way to signal the case temperature–this way the entire lighting scheme would be a unified indicator of the temperature.

Arduino-based Computer Temp Sensing [via Hack A Day]

Jason Fitzpatrick is warranty-voiding DIYer and all around geek. When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson. You can follow him on if you'd like.
