My first 360 died, but it was not because of the typical red ring of death failure, mine actually died because I used a Nyko Intercooler, specifically hoping to avoid a red ring of death, not realizing that Microsoft recommended against using Nyko Intercoolers because they can damage the system. Microsoft Repair team told me that the Nyko Intercooler caused some kind of power surge that burned out the power plug and prevented the system from getting enough power to properly run. 2nd 360 I bought was the Arcade model, reusing my hard drive from my first 360 on it, I've had no issues with it at all, gave it to my sister after back compat was added to Xbox One, and it is still running to this day.
Did Microsoft advise you to not buy X360 to avoid RROD? If not I wouldn't really trust their opinion at a time of what would cause console overheating.
