It is known that all electronic devices do not work at 100% efficiency; they tend to lose an amount of power which becomes heat. There are many ways to combat heat and nearly all of them require a number of fans. As personal computers have evolved and began to consume more and more power, (which correspondingly results in more heat despite them being more efficient) most cooling methods end up noisy because of the fans used. Very few people like dealing with excessive fan noise.
Many companies offer solutions for quiet computing, one of them being Noiseblocker, a German company who design and manufacture high quality cooling fans. We reviewed their UltraSilent and BlackSilent series a few years ago and they were some of the best quiet fans money could buy at the time. Today we will take a look at their latest series, the Multiframe fans, which Noiseblocker claim to be better performing and more efficient even than their own previous fans series.
