Almost 2 years ago I purchased an 8-core Ryzen 5800x but the 5900x was the one I really wanted, you just couldn't find one for sale at the time. My 5800x has been a stable and solid performer, but it tends to run warm. Seems to be a common thing according to many online posts.
The price on the 12-core 5900x finally came down to below what I originally paid for the 5800x and I decided to go ahead and try it, to see if it would run cooler. I know the 4th generation Zen CPUs from AMD are coming soon, but history tells to avoid the first release of any major new architecture and also that even mid-range models will be virtually impossible to come by at anything close to MSRP for at least 8 months, so I plan to use this 5900x for at least 3-5 years and will buy back in at maybe the Zen 5 or Zen 6 generation.
Does my 5900x run cooler than my 5800x? Yes, by around 5 degrees C when idle, though it can quickly rise to be just as warm when editing/converting video or really doing anything which taxes more than a couple of the cores. It reduces back down quickly, however, once the cores are no longer stressed.
There have been a handful of unexplainable system crashes while trying to tune the system BIOS (in the hopes of making the CPU actually run cooler, NOT trying to make it run faster)--I expected the first crash due to aggressive settings, but after backing off most of the way I had 2 more crashes. Backed off a bit more and it's been running stable for the past 30 hours.
I am air cooling with a solid Noctua 90mm dual fan tower in a Phanteks mATX case.
