Unusual heat buildup in the processor with the AMD Ryzen 7 7700
Unusual heat buildup in the processor with the AMD Ryzen 7 7700
Again asking about my current setup. After some time it’s been worrying me that my fans increase unexpectedly when browsing. I checked the fan curve and adjusted it, but nothing seemed to help much. Now I’ve examined the temperatures – they’re quite alarming. Here’s a specific profile: https://spec-ify.com/profile/bd0b0295 PSU: 1000W is quiet! Straight Power 11 Modular 80+ Platinum cooler works well. Dark Rock 4 Pro. I’ve re-seated and tightened all the screws as they should be. That reduced a few degrees, but even in true idle it’s still too high (around mid to high 50s). When I switch to browsing mode with Firefox and Chrome, it instantly jumps to the 60s. Under load it caps around 76-80. Disclaimer: I’m a digital analyst who mainly uses browsers. That’s why I use Firefox for personal work (and I tend to have lots of tabs) and Chrome for business tasks (also many tabs needed). Both programs really tax my memory, but they shouldn’t significantly impact CPU temps – I see CPU usage at just 10% during browsing. I’ll also include a hwinfo log with this post. The first 4-5 minutes are “true” idle. After that, I ran Prime95 and FurMark at the same time. Ambient temperature is about 22°C. I’ve moved from a full custom watercooling build to air cooling again (considering cost and upkeep), but it’s a bit disheartening. I’d be fine with high 30s in true idle and around 40s in browsing mode, but these readings are way too high. Could anyone assist me in resolving this? If you need additional benchmarks, I’ll gladly provide them. hwinfo logging.CSV
While checking CPU Package Power in HWMonitor with your browser open, do you notice sudden increases far beyond the 65W TDP? This is typical since your processor might temporarily boost several cores for quick performance during data loading. If power use is unusually high and triggers temperature rises, your fans are probably running harder to balance things. Consider tweaking BIOS options to limit turbo or adjusting fan curves for better control.
It seems your cooler isn't ideal for today's high-performance CPUs. I've faced similar issues with robust heat sinks before.
Everything is under control. Your normal idle performance is typical; it's not really in the mid to high 50°C range as you mentioned, but around mid 30°C for the cores and high 40°C for the packages. However, it isn't completely idle since Core 1 and Core 4 are still active, which you can see on the second graph. Additionally, your GPU is generating a significant amount of heat—328W—which will also raise CPU temperatures. Even with both GPU and CPU under load, you're only reaching about 80°C. There’s nothing concerning to worry about. Your cooler maintains stable RPMs, staying below 500 RPM until you experience higher loads. If your CPU cooler could adapt its speed to handle temperature spikes, it would further reduce those idle temps, though it might be bothersome to hear if the cooler behaves that way.
Ensure proper ventilation in the case. If the temperature reaches 80°C, it will operate at full capacity, but this remains well within safe levels. Increase the fan speed if needed.
Throttling happens because many CPUs and BIOSes struggle under heat, especially with 3D graphics cards. Likely the cooling system is insufficient or settings are too aggressive. Fix: Replace with a high-quality air cooler such as a Phantom Spirit. Avoid overclocking CPU and GPU; consider undervolting with PBO. Numerous guides are available online.
That explains why my fan curves show a slow increase before reaching the limit, and they maintain around 500 RPM during light loads or when idling. For me, idle means using only 1-2% of capacity, so anything higher isn't considered idle.
The file indicates a powered-on state without active browsing (referred to as "true idle"). During this process, the system logs a fluctuating power draw from 19W to 35W, with occasional peaks reaching up to 55W. This pattern seems consistent with my observations. I notice the 7700 motherboard appears unusual, displaying a star-like shape. I have several cooling units and increase their speed during warmer periods around 60 degrees. Now I’m certain it’s not the CPU cooler, but rather the case fans increasing. Yes, I use "true idle" when I simply boot up without launching any new applications—everything needed for the PC runs automatically. As soon as browsers open, that’s my usual routine for both work and personal use. I’m surprised to see CPU temperatures hovering between 55 and 65°C during browsing, since I expect around 40s, but not the 50s or 60s. Also, I always check CPU temps via Tctl/Tdie; they seem accurate. Concerning the GPU, it’s odd, but its temperature is significantly lower than mine. Those fans are performing well. I might consider adding an exhaust fan, though. I’ve noticed a high positive pressure setup—2x180 and 3x140 intake fans included in the case. I haven’t installed an exhaust fan yet (placed at the back). Under load, I’m not concerned. This isn’t a problem for me. The confusing part is the unusually high normal workload temperatures. Thanks for the cooling advice; I might explore it further. I could potentially reach 1-2% usage during safe boot. My CPU usually stays around 10%, possibly dropping to 5% when idle.
