Hey there, I'm facing an issue with my PC and it seems like the CPU is throttling at low temps. Usually it runs around 63-64°C, but when it hits 65°C it drops aggressively to under 1 GHz or even 0.7 GHz sometimes. I checked the AMD site saying the temperature limit is 95°C, so anyone can help. I used Arctic 5 thermal paste and cleaned the fans, but since the CPU is locked, I can't adjust BIOS settings much. Any advice would be appreciated.

Which board? Which CPU? Which cooler? Likely misinterpreting the power draw of the CPU, if you just raise the power limits—like setting them to an absurdly high number.

What processor are you running? Which tools do you use to monitor temperatures? There seems to be variation in the AMD Ryzen range, such as the 1950X which may show a +27°C adjustment from the real reading. If it reports around 65°C, that's about 92°C overall. Considering possible inaccuracies, it could mean the hardware is throttling due to firmware warnings about overheating. You might be measuring with a sensor that doesn't account for this offset. This is just a thought based on general information.

Are you certain it's the CPU thermal throttle, or could it be power throttling or VRM temperature issues?

VRM isn't causing throttling, I verified that.

Processor is Ryzen 5 2400G, cooler is original AMD cooler, motherboard is ASUS B450. I'm also running the newest chipset drivers and BIOS.

I'm working with Task Manager, Aida64, and monitoring hardware across all systems. I'm also using AMD software for in-game temperatures. My setup includes an ASUS B450, Ryzen 5 2400G, 32GB RAM, 2666MHz SSD, and a Samsung 980 SSD. Running on Windows 10 Pro, I've tested it on Windows 11 as well, and performance remains consistent. I'm using the latest chipset drivers and ASUS BIOS for 2000 Gen support.

No, ProcHot is not listed as the throttle reason in HWinfo.

Verify your temperatures with HWiNFO—it’s available for free and works without commercial restrictions. On a Ryzen processor, you’ll typically see two readings labeled Tctl and Tdie. Tctl displays the CPU’s offset from its real die temperature, while Tdie shows the actual or approximate temperature. Start a game while HWiNFO runs quietly in the background. If the CPU throttles again, compare the maximum reported value for Tctl. A reading around the mid-90s indicates an issue. Also, monitor your VRM temperatures since they can often exceed CPU temps before throttling, though they might also cause instability.
