A good set of fans can prevent your computer from overheating, but they can also make your computer sound like a wind tunnel. Here's how to control your PC's fans to get great cooling when it's working hard and silent when it's not. Sure, you can connect a manual fan controller to your PC and set the fan to a different speed with a knob. But there's nothing like automatic fan control, where your PC starts the fan when it gets hot and turns it off when it's running normally. Fans can be AC Tube Axial for an AC current source, Blowers, or brushless DC Brushless Fans for DC current. There are a number of brands including Adda fans and Sunon fans each with their own specialty designs. Vialetter also carries new products such as coolers, as well as fan accessories including heatsinks, fan guards, and fan cables.
