The Ryzen 2700x at 4.2GHz with a Kraken X72 under stress testing reaches temperatures around 80°C.
I just put in a new CPU cooler and tried pushing my 2700x to 4.2GHz. So far, no performance problems, but I thought it would improve cooling. My motherboard BIOS isn’t very overclock-friendly, so I only adjusted the CPU Clock Ratio to 42 and Dynamic Vcore to +0.282 after some testing. I ran stress tests with several programs and everything seems stable, though I notice my temperatures rise significantly. During a short FFT Prime95 test, they reached around 80°C before dropping back to about 74°C and then fluctuating again. I wasn’t expecting such high temps, especially since normal usage stays within the 60s. For comparison, after this run, my Cinebench temps hit 76.1°C (score 4162). Are these readings unusually high with this cooler? Any advice would be greatly appreciated.
4,2 is essentially pushing the CPU near its maximum boost level of 4,3 constantly, which will generate heat. I also experienced a 2700x to 4.25 setup but the improvement in FPS was minimal, the operating system didn’t noticeably speed up, and benchmarks showed only slight gains in 3dMark etc., though in real-life daily use there were no significant changes. I reset to simpler BIOs OC settings and noticed no differences in normal gaming or internet/streaming performance. A stress test forces the CPU through much heavier workload than any regular app, making it unsuitable for temperatures above 60°C. Your temperatures are actually quite good; I also have a 360mm AIO and rarely exceed 55°C, which is still comfortable this spring.
The CPU is consistently operating near its maximum boost level of 4.3, which will generate significant heat. Previously with a 2700x to 4.25, FPS improvements were minimal, performance gains in the OS weren't obvious, and benchmarks showed slight increases only in 3dMark, though real-world usage didn’t improve noticeably. I adjusted to simpler BIOS OC settings and noticed no changes in normal gaming or streaming speeds. A stress test reveals the CPU handles much heavier workloads than any regular app, making temperatures stay under 60°C. My setup includes a 360mm AIO, and I rarely exceed 55°C even in this season. Ryzens perform well with their optimizations, and I wouldn’t waste resources trying to push my silicon or components for just 2 fps. The self-boost to 4.3 is well controlled, and once the right fan curve is set, it remains stable across tasks.
Thanks for the update. I turned on PBO on the mobo, reset the clock ratio and dynamic vcore back to stock, and ran prime95 small fft again. After about 15 minutes, my temps dropped to 65°C (down from 78°C) and I noticed only a 5% decrease in clock speed, which shouldn't be noticeable daily. When I tried Cinebench 20 afterward, my temps were 67°C (down from 76°C) and my score fell to 3976 (a 4.5% drop). That's manageable.
