This Y power splitter allows you to prvide 12v to the fan and provide power to the hard drive.

Increasing the fan speed increases the output of hot air from inside of your unit resulting in lower temperatures and longer lasting components.

If you system is having issues with locking up during play after a certain amount of time, and then restarting causes the same problem within minutes then it is possible your unit has a heat issue and increasing the fan will help.
