Question Is this Ryzen 9 5900X faulty

[Heeker42]

I am testing a Ryzen 9 5900X, but what ever load I put on it, it keeps throtteling. Temp is low both on sensor and when I touch the cooler.
I runs full load for a very short time

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

The rest of the PC works with other CPU. Owner of CPU complains that he has performance drops at certain loads. It looks better in 3D mark CPU test, but still makes the odd drop to around 600MHz

Without looking into this much further, an A520 is NOT an appropriate motherboard for this CPU. The VRM/power delivery are not suitable. Additionally, that cooler isn't up to the task either.

It would be best to consider not only a better cooler, probably AIO, but also to get a better motherboard. At the very least get as much airflow over that mobo as you can. Even at that it probably isn't going to be enough. An R7 is too much for that board alone.

I'm also thinking the motherboard VRMs are not up to the task.
