No it doesn't. I had to cut the connector off of the original PC fan and the X-Box fan and reconnect them with 3M Scotchlok connectors. Since I am not an expert technician I simply guessed that it would be a standard PWM fan with a proprietary connector. After cutting the cables I connected the X-Box connector to the Noctua fan cables in the same order they left the fan motor of the X-Box fan (from left to right: Noctua: black, ye, gr, blue; X-Box all black). I hope you get what I am trying to say here, since English isnt my first language. I've played for a few hours since and I have no (heat) problems whatsoever.

Thanks to you guys I dared to open my noisy little X-Box and plant a PC fan in it. The noisiest part since is the new 2 TB HDD which I installed while the case was open. Pictures here: https://1drv.ms/f/s!Ap7h5FFmvMougR0R5fCx...
