A quote from the article:
>> Thermaltake Toughpower QFan 650W PSU Review
Today's review is brought to you by the letters W, T, Q, and the number 3. W is for Wolf, that's me; T is for Thermaltake, who sent me the review sample for today; and Q is for QFan, a specially designed fan that Thermaltake believes will decrease fan noise in your standard power supply while maintaining efficient cooling. While the Q in QFan could stand for many things, like Quality or Quigley: Down Under, the Q actually stands for Quiet. We'll have to see if this fabled QFan of yore can be heard over the yowling, screaming exhaust fan in the old load tester, won't we?
