I heard people bought Xbox 360 core instead premium because the temperature differences. Also, people said Xbox 360 core lives longer than Xbox 360 premium for several reasons. Hard drive can heat Xbox 360 increasingly because there aren’t a lot of vents to provide cooling for hard drive and Xbox 360 and there isn't a lot of space to let air out of Xbox 360 premium. Top section of Xbox 360 core has a lot of vents to provide more cooling and give more space to let the air out of Xbox 360 if it doesn't have hard drive. So is it true?
