Silent computing has reached a broader audience, but afaik there's far more revenue to make with gaming and bling-bling products, since marketing people have the opinion that gamers are far more interested in keeping up with the latest hardware available and are more willing to spend money on new systems than Joe Average does.
Silent Computing as a market segment was more clearly visible & thus specifically targeted in earlier years of SPCR -- say from about 2 years after SPCR was created, for upwards of 7~8 years, maybe longer. But with so much of the PC user based affected by mobile computing expansion -- laptops, tablets, smart phones -- and also with real improvement in the noise of mainstream PCs (no, HPs and Dells aren't silent, but they're a lot quieter than they used to be) Silent Computing isn't as sharply demarked as a segment any more, low noise is just one of many parameters that's useful for almost anyone to boast in a list of features. (A key fact is the people just don't spend as much prolonged time at noisy PCs any more; they work on those, then switch to a laptop, a tablet, a phone....) The main point is that it's a much less clear market segment than PC gamers.
In contrast, at IDF in San Fran in in Sept, this static was bandied about: There are 770 million PC gamers in the world. One out of every 10 people in the world, at least, is a PC gamer. Now I'm not clear on exactly where this stat came from, but it is indicative of a real phenomenon. Hardware sellers and makers I spoke with (CPUs, mobos, video cards, etc) say they experienced a boost in sales this year, and it came mostly from gaming enthusiasts. Aside from that & storage, there's still virtually no growth outside mobile computing.
Hence the focus on gaming.
But half the queries in SPCR forums are from gamers wanting to quiet their gaming rigs. lol!
