Continued from page 1 Fans!
You may not realize it because your computer is crammed in a tiny space in a cabinet under your desk, modern computers generate quite a bit of heat. With today's trend of smaller cases, the typical two fans, CPU and power supply, that were found in yesterday's computers, are forced to be the norm today. These two fans are usually blowing at full speed, which causes them to be the biggest noise problem from a recording PC. My everyday computer has seven fans, and I have had rigs with as many as twelve. My rig is very high performance, overclocked 24/7, and a nice breeze inside the case is very important. Case Fans
My everyday computer has a 120mm intake fan in the lower front section of the case that also blows on my three hard drives, a 120mm exhaust fan just under the power supply, and an additional 80mm fan blowing on the hard drives. So, how do I keep these fans so quiet? Excepting the chipset fan, all of them are running at low speeds. The 120mm fans are 50% larger than a standard 80mm fan, so theoretically, running it at half speed will get you 75% of the air movement of an 80mm at full speed...with nearly zero sound. Even if that isn't exact, it is plenty close enough. There are three basic ways to run your fans at lower speeds...running them at a lower voltage, a fan controller...also known as a fanbus, or system control of the case fans. Continued on page 3
