During an interview with Gizmodo, Leo del Castillo, Xbox general manager of console development, revealed some details regarding the internal architecture of the upcoming Xbox One, including its ability to self-regulate its power and throttle down if it detects overheating.
According to Leo del Castillo, Xbox One has much more flexibility than the Xbox 360, as back then, they did not have much choice other than to shut down the console if it could not dissipate the heat. On the other hand Xbox One can actually dial itself back to a lower power state and even throttle down to a mode where it actually does not need any airflow and can be cooled passively.
He also noted that Xbox One was designed so its fan will never get up to its maximum speed, at least not "under normal environmental conditions". Of course, the fan will spin up to its maximum speed if the airflow is being compromised and the good side of the things is that the user will not have to do anything as console will handle it automatically.
It looks like that Microsoft finally managed to get rid of the RROD issue and hopefully we will not see anything similar on the new Xbox One.
