BYU Project to Silence Computer Fans

Posted by CmdrTaco on Thursday May 27, 2004 @05:41AM from the anti-noise-is-nifty dept.

phunster writes "The New York Times has an article about Scott D. Sommerfeldt and his students at BYU who have created a noise suppression system for computer fans (drop of human blood required to read article). The technology is not new, he uses out of phase sound to substantially cancel out the sound of the fan. What is interesting is his implementation of the technique. While other systems place a microphone and speakers in the center of a room, he places four miniature speakers and microphones around the noise source itself. His results are promising."

This is why most modern fans have RPM monitors, and most motherboards have built-in support to alarm and/or shutdown when RPM's fall below a certain level. Beyond that, most current CPU's also have temperature sensors, so that if a fan fails, and temperatures begin to rise, the system will either shutdown, or simply halt.

*to rip from a previous post: Yes, but that post was from timothy. This one is from CmdrTaco. Completely different.
