I purchased a preassembled PC from Materiel.net in France last week (setup link provided). They have a solid reputation and have been operating for a long time. The performance matches expectations on benchmarks like 3DMark, CPU-Z, and Furmark. The issue: whenever the CPU reaches full capacity, the fans immediately increase to 100% speed and the temperature spikes to around 95°C within seconds. I assumed it was just a benchmarking concern due to high load, but it occurs randomly. During tasks like file extraction, encoding for ten seconds, or launching games for over two minutes, the fans react instantly, then calm down quickly once the workload ends. I checked CPU-Z during extended runs and saw temperatures rise before/after, not in real-time stress.

Currently running on an Asus ROG STRIX Z790-E Gaming WIFI with Asus ROG Strix LC II 360 RGB cooling, paired with a Gigabyte RTX 4090 GPU that stays cool under load. The CPU is working well, but I’m puzzled by the unusual temperature behavior. It seems like a software quirk, though the investment feels high. I’m contemplating returning it soon, given the lack of clear cause and the support’s response. I also shared a short video showing this pattern. CPU Stress.mp4

This setup seems typical for its intended purpose. However, the 5500 model is quite expensive. It appears they didn’t include a proper case frame, which affects airflow. The rog isn’t particularly strong, though it’s not terrible—just not the most efficient option compared to better models. The case also has limited airflow, and the fans are working harder than necessary by drawing in hot air from inside while trying to push it out. The 13900k is an extremely hot processor. Overall, this setup looks like it wasn’t built with reliability in mind; using a more balanced workload, like Cinebench R23, would be a better choice.

I plan to run a Cinebench test once I’m back at the computer. Sadly, I’m on travel for work, so it might take a few days. I’m wondering if the issue could be related to temperature or cooling performance—wouldn’t it be strange not to see normal temperatures after the load? I suspect the reported readings might not be accurate, which is what’s confusing me. I’ve had a 5960x before, so I’m used to CPUs that use less power and don’t behave this way. My only cooling was a Noctua air cooler.
