I recently built a new PC and everything seems to be running well, but I'm concerned about the CPU temperatures I'm seeing during benchmarks. I'm using a Montech Hyperflow 360mm AIO cooler, aiming for a quiet setup. The 7700X has a maximum listed power of 143W, yet my temps are hitting around 85-90C during Cinebench, which seems unusually high compared to reviews that report lower temps at similar power levels on more powerful CPUs under lighter loads. While I understand that my CPU may have a less efficient heat spreader design, I'm seeing a 30C higher temp at the same power ratings. Additionally, I've noticed that the temperatures fluctuate almost instantly at the start and end of tests, which I didn't expect. I would love some insight on whether this is typical behavior or if I should troubleshoot the cooler installation since I believe I followed the instructions correctly, using the pre-applied thermal paste.

Yep, totally normal. The 7700X tends to ramp up to 5.4GHz until it hits that 95C mark. Under full load, seeing temps around 90C isn't out of the ordinary. Just ensure your cooling solution is working efficiently.
Honestly, yes, that temp range sounds pretty normal for the 7700X, especially when you're pushing it in Cinebench. It’s like flooring a car in neutral! Just keep in mind that your CPU can handle temps up to 95C without issues. As long as you're not exceeding that, you're fine. If you're running your fans at 100% when you hit 80C, you might be creating more noise than necessary for no real gain in cooling performance.
You're fine for sure. These chips are designed to boost up to 95C, so reaching around 90C under a full synthetic load is actually good. If the noise is bothering you, consider lowering your fan speeds to find a balance that works for you without affecting performance too much.
Yeah, AMD designed these chips to be tolerant of high temps. The thick IHS and compatibility with AM4 coolers can lead to higher heats. I went with a big air cooler for my 7700 and saw similar results. You might want to look into undervolting if you're up for tweaking – it can help lower temps and keep things quieter without sacrificing much performance.
