"The Nyko Intercooler has also been reported to have caused a general hardware failure in a number of consoles, as well as scorching of the power AC input.[22] Microsoft stated that the peripheral drains too much power from the console and can cause faults to occur, [23] and stated that consoles fitted with the peripheral will have their warranties null and void. Nyko has recently released an updated Intercooler that uses its own power source. Nyko claims this problem no longer occurs with new versions of this cooler. However, Microsoft still considers it an unlicensed add-on and will void the warranty of machines showing signs of its use. There is no data available to indicate whether Intercooler decreases the chance of hardware failure".
