Have trouble understanding unusual CPU temperature problems.
Have trouble understanding unusual CPU temperature problems.
Hello. I'm experiencing some unusual temperature problems with my Ryzen 7 3700X CPU. It usually stays under 70°C even with the cooler I have on it, but this has changed recently. My desktop has several gadgets, including an 8-pack of accessories. The CPU is connected to the core temperature sensor, which monitors its readings and triggers an alarm if it exceeds 75°C. Recently, while playing Battlefield 5, I noticed the temperature alarm activated, causing me to close the game. According to the core temp data, it reached a peak of 78°C during loading, then briefly spiked to 83°C in the CPU Test tool. This sudden rise is concerning. I've also run Prime95 and Cinibench, where the CPU consistently stayed at around 68°C. However, with Battlefield 5 and Time Spy, it overheats quickly—sometimes dropping to base speed by the time the temperatures climb. I'm unsure why this happens only with those applications and not under normal use. How can I figure out the cause and fix it? This wasn't an issue before.
Do you frequently test benchmark simulators? With a 3700X you can utilize Ryzen Master and let it maintain performance above 75C, while my 2600X won’t begin to slow down until 95C. It’s advisable to run HWINFO64 to check if throttling is occurring or if you suspect it is. Ultimately, a repaste and remount could be the solution. Also remember that synthetic and real-world tasks differ significantly.
I don’t rely on pbo or overclock settings. My cooler isn’t up to the task. The best way to keep things stable is to run at stock performance, which I’m doing. I plan to repaste and remount it. I’ve done some maintenance recently. There’s a chance the thermal paste dried out too. I’ll need to buy fresh paste. My old Arctic MX4 tube broke and is beyond repair. It’s strange it works fine with small loads but fails under heavy demands like loading Battlefield 5. This has never happened before.
It's mainly about how much work you're handling. Over time, prime95's workload has gotten more efficient thanks to improved IPC, making it better suited for tasks like small FFTs. Even with a slow handbrake 1080 on my 5800H, it runs smoothly and manages the heat well. However, Forza Horizon 4 at high detail causes the 5800H to quickly reach 93%+ and stay there.
