Have you ever put a lot of effort into creating something, only to have someone else come by and say, "Hey, this already exists!" This is commonly phrased as reinventing the wheel, and refers to a duplication of a method or an object that has already been created or optimized by others. For example, if I told people I was in the middle of inventing a portable power source, which could be recharged and reused just by plugging it into an outlet, you would probably smack me, pull out your nickel metal hydride or lithium ion batteries, and tell me how many years I am behind. However, if I were to say there was a new battery technology offering years of power, decades of shelf life, you would probably turn your head to at least hear me out. If I could claim these batteries were fully rechargeable, and made from some readily-found materials, you would probably be asking me why I have not patented this yet. Thus, before I continue to write this review, I will finish submitting my patent for the newest battery technology using acetic acid and kerosene. This technology does not actually exist, but proves while you may not necessarily want to reinvent a new idea, improvement is always something to keep striving for. All kinds of technology can be optimized, whether it is to reduce power consumption, reduce heat loss, or increase performance and efficiency. Today is a review of the Fractal Design Venturi fans, both of which offer some new optimizing features focused on reducing noise, increasing efficiency, and increasing performance. While these may be small changes, I can only wonder if these have created a huge difference. Hopefully my curiosity and yours will be relieved as we get into the Fractal Design Venturi HP-12 PWM and HP-14 PWM.
