5900X is easier to cool than a 5600 though; The 142W PPT is divided between two CCDs so the most power going through an individual die is typically under 65W (~15W or so for the IO die)
Even the non-X single-CCD Ryzens are getting 88W PPT, of which typically ~75W will be going through the single die. It's not a huge difference in absolute terms, but we're talking 15% higher wattage through the same area of silicon. The 5800X is the real problem chid because that's trying to cool almost 130W in the same area.
With Zen3, the issue is rarely "too much heat overwhelming the cooling", it's more that the heat density in the die is overwhelming the thermal transfer of the solder, IHS, and cooler baseplate. Whenever a Zen3 CPU is saying it's hot, you'll often find that the air coming off the heatsink or radiator is cool or lukewarm; Unmounting the cooler to check the mounting pressure and inspect the thermal paste is a step I've done many times on many builds when I see high temperatures, but it's never been that - it's simply that Zen3 is subject to hotspots in the die, and some motherboards exacerbate the issue by applying very aggressive voltage curves by default.
Nine times out of ten, I can get Zen3 temperatures down by 10-20C by simply going to curve optimiser and setting a -10 offset on all cores. No other changes required and cooling/fan curves/PBO/PPT/TDC/EDC all left as they were. I'm not sure if -10 CO offset is guaranteed stable on lower-bin CPUs like the vanilla 5600 but I've never had -10 cause instability on 5800X/5900X/5950X and in my own rig I run per-core offsets ranging from 15 to 26 based on HWInfo and some stress testing to find the limits.
A tuned system with optimised voltages can run a single-CCD Zen3 CPU at relatively low temperatures even when beyond max advertised boost on all cores.
At the same time, there are countless threads around the web proving that these chips can get hot, even with decent cooling. It's likely all down to variance between boards and BIOSes. Manufacturers playing it safe will likely just pump up the voltage to ensure it's fast and stable.
5600, (5600G iirc), 5600X, and 5700X all have a PPT of 76W. They do not follow the otherwise true 88/60/90 rules for 65W TDP parts, and accordingly are by far the easiest to cool Zen 3 parts.
The 5900X isn't always as trivial to cool as you make it sound. The high Fmax of 4950-5150 can easily see a single core drawing close to or equal to 20W in heavy loads. Like you said yourself, all of Zen 3's heat problems come from thermal density, which in turn stems from high per-core power.
5600 and 5600G have a Fmax range of 4450-4650, which makes it borderline impossible to heat up to the levels of 5800X/5900X/5950X without manual OC.
Even at 4650 PBO the per-core draw never gets high enough and my 5600G peaked around 60C on a L12. 5600G and 5600 have different physical layouts but at their low power draw thermals are comparable.
Hello,
What are Ryzen 5 5600 (Non X) Normal Temperatures?
I just upgraded from a Ryzen 5 2600 to a 5 5600.
With the 2600 my temps when idle were between 30-35C but i did not pay attention to what it used to be while gaming. But now after upgrading to the 5600 with just my browser, steam, ICUE and Dragon Center opened my temps would stay between 48-55C sometimes it would randomly spike to 60C for like a second or 2 and when gaming (I tried phasmophobia, Darktide, BF2042 and MW2 to check the temps) it would stay between 55-62C sometimes it jumps to 65.
Is this normal because of the Ryzen 5 5600 heat density? i don't use the stock cooler it came with, i'm using the AIO Cooler Master masterliquid ML240L v2 240mm on the front side of my case.
Should i reinstall the AIO and/or re-apply thermal paste?
This sounds like you might want to check your mounting pressure and paste application.
BF and MW19/MW2 are rather heavy AVX, can heat up one or two cores significantly, and will generally run on the warm side for Ryzens, though how much depends on the CPU. Knowing that, and if your room ambient is on the higher side, and if you are running PBO settings, then 65C isn't unreasonable.
The problem with water of any kind on Ryzen is that there is only so much it can do for thermal density-related temp spikes. It's only when you crank up the pure power that water can really show it's advantage, which is only really applicable to 2CCD parts.
