Swaying CPU Fans

Posted by CmdrTaco on from the floating-in-the-breeze dept.

Vindi submitted a New Scientist story about a CPU fan that flaps in the breeze. 2cm metal or polyester fan blades, and use less power then a traditional rotary fan. They move less air then the traditional fan, but for laptops, using 99% less power can't hurt. Update Hey its a duplicate from saturday! Guess I shouldn't post while planning my trek to see LotR tomorrow. Go ahead, flame on.

  1. Peizo fans are at least 15 years old by b1t+r0t · · Score: 5, Interesting
    I had a peizo fan in my old Mac (a 128 with a Levco MonsterMac 2 meg upgrade) back in 1986. It had two strips (about 1cm by 4cm) sticking out of the top, and the strips vibrated. It was held in there by velcro and just pushed the air around. (It did not attach to a CPU or anything like that.)

    It's kind of hard to tell exactly what this article is describing, but it sounds like exactly the same thing at half the size.
