That and 360 AIO's are not terribly cheap, the good ones.

AMD to unveil Zen 4 CPUs at CES 2022

A good air cooler is as good if not better than a good AIO, which makes this all a bit hyperbolic.
Its simply a case of using one inadequate cooler vs not, for the clicks, because people fall for it.

That’s the exact reply I would have expected to your previous post. That would make more sense.
It’s “figured “ by the way.

There are no absolutes to anything, i did say i was not being completely literal, of course you can have inadequate cooling, at the other end there are diminishing returns.
Zen 3 and by extension Zen 4 has a much higher thermal density compared with Intel, that presents its own cooling challenges.
Caporegime
Something the size of a 1£ coin generating 200 watts of heat is going to be easier to cool with a 250 watt capacity cooler than something the size of a 5p coin generating the same volume of heat.
Simply using a larger cooler is not going to solve that problem, not completely because the cooler is not the problem.
Using a 150 watt cooler, that would be a problem.

I think it’s a struggle to keep any high end AMD CPU cool. From what I’m seeing people seem to normalise high temps that I would find unacceptable.
The example you showed didn’t explain that it was a higher end AIO vs a lower end air cooler, which is why it didn’t make sense.
If someone is buying high end parts, it’s totally pointless buying a cheap cooler and your example proves it.
People are going to want to see fair comparisons, not silly ones.
Caporegime
What i'm saying is you have to buy a reasonable cooler, a high end one is not a must.
i have a 360mm AIO on my 5800X, it still reaches around 82c, people with the same CPU using a 240mm version of the the same cooler get exactly the same temps, of course they do, for reasons i'm trying to explain.
Also, don't get so hung up about 80 to 90c temrpitures under high load, its completely normal, it doesn't do them any harm, they are designed to run like that.
what workload are you doing to get 82c and power draw ?
Soldato
I would argue 90c on a heavy workload is not really harmless. The combination of wattage + temperature is what literally kills CPUs, I wouldn't be confident running any CPU for hours at 90c in these kinds of workloads. For gaming, i don't care, it can hit 99c for all i care. But electromigration is a **tch when you are running high wattage + temperature, it is knocking at your door.
With that said, until proper reviews come out, it's all just rumors.
I’ve never had a CPU die from heat. Even if a CPU was running at 90c 24/7 it would probably be fine for a long time and that is an unrealistic work load anyway. Temperatures only become a problem if the CPU is throttling to meet its max temp. Otherwise, most of the time I don’t care what temperature it’s at so long as it’s quiet…

Aida64 stress test, about 100 watts on the CCD.

Would you be comfortable with 105c? because many Intel Laptop's run like that under a high load.
Soldato
Nope I wouldn't!
Soldato
I would hope that the engineers set up firmware parameters that allow for the CPU to last the length of the warranty period under worst-case scenarios.
Soldato
I assume they are not running 20 hours encodes, are they? I mean that's not what they are meant to do. You don't buy laptops to run long hours of f@h renders and encodes.
Also, are those laptops you are talking about running their CPUS at 200watts? Cause it's the combination of wattage + heat that kills cpus, not heat by itself. So...yeah
Permabanned
These CPUs are so popular we need two threads to argue minor ******** on. 
Soldato
Says who?
Soldato
Says who about what? Laptops not running encodes and f@H? Me. He asked me whether I would be comfortable with my laptop running at 105c, so my answer is absolutely yes, since I don't run heavy long hour workloads on them, and they don't have the CPU running at 200 watts, so even if I was running heavy long hour worklaods on them it would be at very low wattage (30-40 or something like that).
Caporegime
Some do, for sure,
The GDDR6X memory IC's on Ampere cards run at 100c + every time you use it for what its intended.
How do you like your 3080 now?
