Performance at high temperatures with the Ryzen 9 7950X3D
Performance at high temperatures with the Ryzen 9 7950X3D
Hello everyone! I recently purchased a Ryzen 9 7950X3D to boost my gaming experience, particularly for VRChat. I've noticed the CPU overheats quite quickly—often reaching around 80°C during background tasks. Updating to the latest Nvidia Game Ready drivers caused it to spike to 90°C for a short time, which seems unusual. I'm using the Be Quiet! Silent Loop 2 240mm for cooling, placed at the top of my Fractal Meshify 2 Compact RGB case. The cooler might not be functioning properly; the fans spin, and the pump operates at full speed according to Fan Control. I've benchmarked my CPU with Cinebench, which showed a peak temperature of 90°C and a maximum of 90.3°C. Reviewers rarely reach that high, usually staying around 87°C or lower. My AIO pump fans are also running at full capacity. I scored 35,652 points for multicore and 2,006 for single-core performance, which is below expectations based on typical results (usually around 36,500 and 2,065). I'm concerned because the TJMax for this processor is 89°C, which is higher than my readings. My setup includes a Seasonic Vertex GX 80 PLUS Gold 1200W power supply, the Ryzen 9 7950X3D, an Asus ROG Strix X670E-E gaming GPU, the Be Quiet! Silent Loop 2 240mm with Arctic MX-6 paste, G.SKILL Trident Z5 NEO 32GB DDR5 6000MHz RAM, and Windows 10 64-bit. I'm using the latest AMD BIOS and chipset drivers. Although the documentation is in German, I've shared some monitoring data from HWInfo64 during my Cinebench tests. Thank you in advance!
I’m not sure if you’ve explored much about Zen4 yet, but it seems perfectly reasonable to me, especially with a 240 AIO. Many new users of Ryzen 3 and 4 struggle to grasp these concepts, but the temperatures around 80s and low 90s are expected and built into the design. This understanding has been clear since Zen4 was introduced. The processors are built to run at 95°C and are comfortable in that range. Your top choice would be to consider undervolting with Curve Optimizer or setting temperature/power limits, though what I’m seeing doesn’t seem unusual or problematic.
Might require more than required voltage for the CPU as determined by the motherboard's BIOS. Increased voltage causes greater heat generation. 90°C for 7950X3D is typical, similar to 95°C for my 7950X, for instance. Before Zen 4 I had a 5800X and Gigabyte X570 Aorus Elite; those boards usually overvolt the CPU by default. BIOS would push it up to 1.4-1.5V, reaching 90°C and then climbing to 4.3GHz when the advertised 4.8GHz was reached. After extensive undervolting and PPT EDC tweaks the CPU stabilized at 4.8GHz with cooler temperatures dropping from 90°C throttle to 74°C and a quieter fan profile. My 7950X also responds similarly even with negative -35°C undervolt—still hitting 95°C but reaching 40k points in Cinebench. Experiment with undervolt definitely improves performance.
Remember again, upgrade the cooler or lower voltage but your results and temperatures remain normal.
I see, I mixed up Zen with the socket earlier. The online specs seem more impressive, possibly due to better cooling or open-air testing. I didn’t try undervolting and it feels quite complex, so I’m unsure whether to make any changes. Maybe I’ll consider a cooler like the Deepcool LT if it fits my needs.
In recent years, from Zen3 to Zen4, it becomes clear that focusing too much on temperatures isn't very useful with these processors. Zen4 is built more like a laptop chip, aiming for higher maximum temperatures by design. Instead of tracking temps, pay attention to core clock speeds and benchmark scores for comparison with other users or chips.
It seems you're probably overthinking this. Since I haven't done any undervolting before, I'll need to check it up. Thanks!
I'm managing my 7950X3D with a quiet fan and the Dark Rock Pro 4, achieving outcomes quite close to what I see. I'm a bit concerned about occasional spikes above 90°C, reaching up to 94°C during tasks like shader compilation or loading a saved game in Last of Us, followed by a rapid drop to around 75°C. During gameplay it maintains roughly 80°C, while other titles stay nearer to 70°C; the Last of Us appears particularly CPU-intensive. I've played through the weekend without issues, now in chapter 5. I expected such high temperatures to limit performance, but it continues to run at over 4.2GHz and still exceeds 89°C. I suspect this is within normal limits, though the non-3DV CCD can reach up to 95°C similarly. However, I wouldn't run it while the game is active. It seems reasonable at 130W even at thermal limits, and idle temps remain around 50°C. I own an AsRock X670E Pro RS board.
