I upgraded my testbed from Intel Core i7-8700K to AMD Ryzen 7 5800X. And I must say, the Ryzen 7 5800X brings a nice boost in performance. With its 8 cores / 16 threads, it shows around +60% gain the physics score of 3DMark FireStrike benchmark (17988 points for the core i7-8700K vs 29503 points for the Ryzen 7 5800X).
In CPU-Z benchmark, the Ryzen 7 5800X is +22% faster in single thread and up to +70% faster in the multi-threaded test:
Ryzen 7 5800X:
First time I really appreciate an AMD CPU!
Enough with CPU benchmarks, the web is full of these kind of tests.
The Ryzen 7 5800X is shipped in a box that has enough room for a CPU cooler… But instead of a CPU cooler, you have this: a piece of cardboard.
Fortunately, I have two CPU coolers in my lab:
- a Dark Rock 4 (be-quiet!) which is a 200W TDP cooler for AMD and Intel processors.
- a Wraith Stealth (AMD), a CPU cooler designed for a 65W TDP processor (like the Ryzen 5 3600).
The Ryzen 7 5800X is a 105W TDP processor. Even if the Wraith Stealth has been developed for a 65W TDP CPU, let’s see if it can cool a 105W TDP CPU.
The Wraith Stealth CPU cooler (shipped with some AMD CPUs):
The Wraith Stealth trying to cool the Ryzen 7 5800X:
The first test I did is to enter in the BIOS and see the CPU temperature at idle. After few minutes, the CPU temperature reached 58°C.
58°C is hot but the Ryzen 7 5800X can run up to 90°C.
Now let’s start Windows and AMD Ryzen Master. At idle the CPU temperature is 35°C:
Why this temperature is lower than in the BIOS? Probably due to the CPU voltage: in the BIOS screenshot, you can see 1.408V and on the Ryzen Master screenshot, the CPU voltage is 0.986V. A higher voltage leads to higher CPU temperature.
Ryzen Master has a built-in CPU stress test:
On the screenshot, the CPU temperature reached 83°C. Great! The Wraith Stealth cooler is able to dissipate all the heat produced by the Ryzen 7 5800X.
Another CPU stress test: the CPU Burner shipped with FurMark:
Ouch! The max temperature (90°C) is reached in few seconds.
Conclusion: the Wraith Stealth CPU cooler can cool a Ryzen 7 5800X at idle and under moderate CPU loads. For higher CPU loads, a serious CPU cooler is required, like the Dark Rock 4:
CPU temperature in the BIOS: 47 °C:
Ryzen Mater at idle: 29°C:
Ryzen Master stress test: 67°C:
FurMark CPU Burner: 83°C:
The Ryzen 7 5800X is a processor that can generate a lot of heat. A high-end CPU cooler is required to enjoy this great CPU. I will try to update this article with a test of the Dark Rock PRO 4 CPU cooler.

Interesting would be Cinebench. There I reach with Dark Rock 4 5800X over 90 degrees and the Boost reduces a bit.
because there are over 140Watts and in your Benches just 110W
Thanks, just had my AIO pump fail. Cannot live without my PC and figure going the tech support route will take 2 weeks at least before I seen a replacement cooler. Was kind of pissed at having to spend more cash on a decent cooler. But if I can get away with the wraith stealth for a few days, it is only a few bucks.
