This explains why upgrading to a better cooler often fails to meaningfully lower temperatures, since the CPU simply uses the extra thermal headroom to boost clocks further. The author recounts personally misdiagnosing high temps on a Ryzen 5900X as a cooling problem before realizing motherboard power presets were the real cause, and recommends checking BIOS settings, monitoring power draw, and considering undervolting (as done on a 5800X3D using PBO2 Tuner with a -30 Curve Optimizer offset, cutting temps by 4-5C) before blaming the cooler. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does my CPU run hot even though I never enabled PBO or changed any BIOS settings Motherboard manufacturers often apply their own aggressive performance presets by default, even when PBO or similar boost settings show as 'Auto' in the BIOS. These presets can relax AMD's stock PPT, TDC, and EDC limits (or Intel's PL1/PL2 limits) without the user manually overclocking, letting the CPU draw more power and generate more heat than the vendor's stock configuration intended. _Anyone chasing unexplained CPU temperatures can find hardware troubleshooting breakdowns like this through daily.dev._ ### Will upgrading to a better CPU cooler actually lower my gaming temperatures Not necessarily, because a CPU with extra thermal headroom will often just use it to boost clocks higher rather than run cooler. Since modern CPUs already boost aggressively at stock, a high-end AIO may barely reduce temperatures if the chip keeps pushing against its power limits, so checking motherboard power presets or undervolting can matter more than cooler quality. _Before spending on a new cooler, PC builders can weigh trade-offs like these using guides surfaced on daily.dev._ ## Similar posts on daily.dev -
