bobmitchActually the 5800X is considered a "Hot Head" because of the single CCD https://www.techpowerup.com/forums/threads/ryzen-5800-owners-complain-about-very-high-mt-load-temps.274465/ The upper temp limit on the 5900 and 5950X is 95C, and the 5800 is 90C. The load temps on the 5600, 5900 and 5950X are lower. However...once tamed...they really shine! All in all...the 5950X may idle slightly higher than my old i7 7820X, but at full load...the Ryzen is cooler and much more powerful.
