This device keeps your CPU fan and an additional fan running for five minutes after your computer shuts off. The Extended Cooling System is a very simple and an effective addition to any air cooled computer. Installation is very simple and can be integrated into nearly any system. Whether system damage can occur from not cooling your system with the power off is debatable. This device ensures you will not have to take that chance, especially if you are overclocking. It is always nice to have a piece of mind when it comes to cooling our computers and the ECS offers just that. This model features the look of a GT race car! Way cool!
