USB Computer Case Fans
USB ports are those handy little ports on the side of your laptop or the back of your computer tower, and are arguably one of the most useful elements of any computer device. Now a standard feature of any modern computer, laptop or tablet, USBs can be used to operate a myriad of external devices from computer mice, keyboards and external storage and can even charge your mobile device. Now, USB computer case fans are rising in popularity as computer users begin to realise how handy and useful they can be.Functionality and Accessibility of Computer Case Fans
Computer case fans are infinitely useful, and come in a range of forms and sizes. USB computer case fans are any computer case fans that operate from a USB port, allowing a computer user to make use of one of their unused USB ports to keep cool. A computer fan pulls in cooled air from outside the device, reducing the temperature inside the device to prevent it from overheating.The Restrictions of USB Computer Case Fans
While fans can range both in design and size, with 120mm USB computer case fans and 140mm USB computer case fans being two of the more popular and well-known sizes, all devices that run from USB ports have the same restriction. By design, USB devices can draw no more than five volts of power, ultimately limiting the application of a USB fan to personal, desktop use.How to Use a USB Fan
There are several uses for a USB computer case fan, many of which could potentially save the user from disaster in the long run. Electronic and computer equipment draws a lot of power and creates heat, with many prone to overheating. Just rest a laptop without sufficient cooling on your lap for a few minutes and you'll notice just how much heat it can generate. Even if a computer or laptop can keep itself cool when first purchased, built-in system cooling can be one of the first elements of a computer to break down or lose functionality as the equipment ages. It is then that USB computer case fans can prove essential, potentially saving you from the frustration of a decline in your computer's performance, or the cost of a new machine in the event of overheating.
