I've been monitoring my CPU temperatures for some time and haven't managed to get them in the right range. I'm wondering if the temperatures I'm seeing are realistic considering my current hardware configuration. I have a Ryzen 5900X with whatever turbo settings it has, and I haven't adjusted the BIOS overclocking settings. It's paired with an NZXT Z63 cooler, which is starting to feel a bit restrictive. I'm using a Corsair Crystal Series 680X case. First of all, CAM seems to be problematic—it changes fan speeds too frequently, making fans work harder just for minor distractions like opening a browser tab. Argus Monitor works well, though it requires some manual tuning of settings.
Your question is whether these temperatures are normal. At startup, I've seen readings around 65-70°C, then dropped to about 62°C and stayed there. This was due to a bug in the GoXLR App that limited CPU core usage; after fixing it, it settled at roughly 42-45°C and stayed stable. However, whenever I switch tabs—like opening Vivaldi or doing anything else—it quickly spikes back up to near 65°C.
I'm not sure if such rapid temperature fluctuations are normal for my setup. Could you help me understand what's physically possible with these components? Please share more details or a screenshot from Argus Monitor if you can. Thank you!
I'd say you're fine as long as it stays around 80°C or so under load. Obviously lower is better because Ryzen automatically clocks higher with lower temperatures. But we're talking about a few MHz, so nothing that'll significantly change performance. Your clocks only drop in a significant way when you reach temperatures like 85°C or up and the CPU thermal throttles. With Intel CPUs you can go even higher before it starts to thermal throttle. And generally speaking temperatures are fine as long as you don't see any throttling. Laptop CPUs often run at 85-90°C for most of their lives and they're still among the most long-lasting components in these machines.
I tried but couldn't shape the curves as expected. The logging tool helped since I was experiencing unexpected resets, which I suspected were due to overheating in the RAM. I decided to keep using it afterward.
It's nice to hear that! If you followed through, you'd likely experience thermal throttling quickly. The NZXT AIOs didn't quite meet expectations, but the OLED display seemed appealing at first. Thinking about upgrading to a Noctua D15 makes sense if you can afford it. I'm curious about CPU-Z's stress test reliability—its 24-thread AVX2 results stayed around 70-72°C for over an hour at 4.27GHz.
Download Cinebench R21 from the Microsoft store and run it continuously for half an hour. If the temperature remains below or near 80°C during that time, everything looks good. It's typical for clocks to slow down when more cores are active. A speed around 4.2GHz should be expected from most Ryzen processors under heavy use.
I'm quite content with my D15 setup, though it won't be anything extraordinary. My 5800X consistently reaches around 80°C during peak loads. It climbs quickly and drops just as swiftly, especially when the chip enhances performance through roof thermals. The temperature spikes happen in two ways: sometimes the CPU temporarily stalls to speed up loading, causing a brief rise in heat, or sometimes loading slows down. Since you're not experiencing overheating, you probably don't need to worry about these fluctuations.
