Nexus Prolong:Extra Cooling after PC shut down

Nexus Prolong:Extra Cooling after PC shut down


The Nexus Prolong will provide extra cooling time after your PC has been turned off!

When a PC is turned of the temperature of the CPU rises considerably because the active cooling has been turned off. The Prolong extends the cooling time to preserve the components.

Once you have turned off your computer the Nexus Prolong will start operating and will keep the connected fans running for approximately 5 minutes. The fan power/speed is brought back to 5V instead of 12V to reduce the fan noise, yet provide sufficient airflow to reduce the temperature of the CPU and the entire system significantly.

This feature is used in many of the luxury cars these days to extend the cooling time and increase the lifetime of the components.

The Nexus Prolong is equipped with an LED. When your PC is turned on the LED is green, once your PC is turned off the Nexus Prolong will do its job and the LED will turn red.

You can connect up to 2 (3-wire) fans to the Nexus Prolong.

............... "A very useful device which helps to cool down your pc components for 5 minutes after the pc is turned off. Very easy to install and you can connect up to two fans. "

PC Extreme Magazine......."You've been happily gaming away, torturing your hardware to within an inch of it life, and then you have an urgent desire to do down the pub. Have you ever thought about what happens when you turn your PC off? If it's been working hard, many of components are still going to be pretty warm, but when you switch it off, you suddenly remove all the cooling.... Nexus has thought about this, and has come up with a nifty device called the Prolong."
