High temperatures at 2600 MHz with 3.8 GHz performance under running Cinebench r20
I've been attempting an overclock on my recently purchased Ryzen 5 2600, but experiencing extremely high thermals. It's preventing me from continuing tests to avoid damaging the system. Currently set at 3.8ghz with a voltage of 1.3175v, I reached temperatures close to 90°C during a single Cinebench r20 run. I'm using the included Wraith Stealth cooler, though I plan to upgrade to something more powerful soon. Observing online reports, the temperatures are significantly higher than expected. I've been monitoring with HWINFO64, and idle temps are around 40°C. Even at the stock configuration, temperatures approach 80°C. After applying paste (Deepcool z9), ensuring proper cooler installation, and adjusting the CPU fan curve more aggressively, the situation remains challenging. The build includes an MSI B450 gaming PC with Corsair Vengeance LX 3000MHZ, an EVGA GTX 1660 X, an Adata SP900 256GB, and a Deepcool DA500. I understand the Stealth cooler isn't ideal, but I suspect another factor is involved—anyone have any suggestions?
To push it even further, you'll need a superior cooler than the standard one. 90 isn't too extreme during stress tests since you won't reach that level with your computer on a regular basis. Regardless, if you're aiming for overclocking, I recommend a high-end air cooler or a water cooling system.

Is there a cause for concern about the vcore being at 1.3v? You should be able to achieve stable 3.8ghz across all cores at around 1.2v or lower without much trouble. Unless you have a unique setup, lowering the voltages might help. At 1.15v I experienced full stability with a 3.8ghz all-core overclock and 85c max performance using the stock cooler during prime95. Your results might vary, so use these numbers as general guidance.
With all due respect, the claim about your CPU being stable at 1.15 volts and 3.8Ghz is incorrect. The standard voltage is closer to 1.23. Even if it doesn’t crash immediately, stability isn’t guaranteed. It’s unlikely you’d survive 8 hours of realbench testing with those parameters.
I didn’t really plan to stay hidden, just assumed the temperature was still too high. My Evo is arriving tomorrow, so I’ll find out what effect it has.
I understand what you're doing. I haven't tested lower voltage yet; I looked at the current draw at 1.3v and began there. The heat limited my options, so I'll check how much further I can reduce the voltage.
The fans are Corsair AF120 LED white, a bit outdated but still functional, connected to a multi-channel controller.
An hour and a half of prime95 performed without any crashes or failures. In reality, I won't push my CPU to that level for such extended periods. It might become unstable after an eight-hour stress test, but I'm just playing games and streaming videos.
