Check the idle temperature and voltage settings.
You've built your first PC and are monitoring its performance. Your temperatures seem typical for a system with the Ryzen 7 7700 and stock cooler. The spikes you're seeing are common during heavy workloads, especially when the CPU is under stress. With 2 fans installed so far, you're on the right track, but ensure proper airflow and case ventilation. Keep an eye on temps during gaming or benchmarking; good tests include Cinebench R23, 3DMark, or a custom stress program. Your current setup appears stable, just monitor closely as you add more components.
The 7000 series from AMD is built to operate continuously at high temperatures, which sets it apart from earlier CPUs and Intel models. The standard cooler suffices, but upgrading to something like the Peerless Assassin would yield better performance. On my 7700x with an NH-D15, temperatures stay between 60-80°C during intense gaming at a steady 30% fan speed. Your temps are comfortably within the recommended range and won’t harm the processor, as it’s engineered to reach 95°C. This behavior is unusual but intentional.

Oh, ok! I was used at lower temperatures lol Just now, I played Genshin Impact for a little bit, and I was so excited and happy for my new system, because it's my first ever gaming pc! I've only had a laptop for a long time. As I said, I played genshin, and I've put everything on max settings: EVERYTHING! 1440p @ 60fps (because the game doesn't go over 60 lol). GPU was at 60°C at most, and maybe the usage was even under 90%, CPU went at 75°C while loading, and it stayed at around 70 for the most part. The only strange thing, is minecraft... I loaded a new world, and I started wandering around, I had maybe 12 chunck rendering, and while I was flying around FAST, the CPU reached 90 degrees! It's the only game that, it's simple, but very heavy "thermally". Maybe in the future I will upgrade to a Noctua NH-U12S, black of course
But what if we lower the voltage on the CPU? You're right, browsing the internet doesn't require it to run at 4.8GHz. The GPU already has fans spinning at low speeds, and it stays cool between 50-60°C. Even when things get busy, with fans running, it doesn't exceed 60 or so, maybe a bit higher under heavy use.
Avoid lowering the CPU voltage—it's built that way. You can enable ECO mode in Ryzen Master, but sticking to the default is best. The processor will reach 4.8Ghz, ensuring smooth performance without slowdowns or stutters. You'll get a responsive system right out of the box. Most contemporary GPUs include a fan stop feature, which helps reduce noise during tasks like web browsing or YouTube watching.
Normal variations exist in how games affect your GPU performance. A few titles really push your RTX 4080 to its limits, while others barely notice any impact. I noticed Construction Simulator 2020 handled it well with high fan speeds, whereas Dying Light 2 on ultra felt okay at around 65c. It seems some games are more demanding than others.
Well, turning off the fan might cause the CPU to overheat quickly, but I see what you mean. At 4,8Ghz when the PC is just on, maybe background downloads are happening without active use. There should probably be an option to reduce the base frequency a bit. I notice high temperatures when playing, but not so much during basic tasks. I’m hoping this PC will last at least five years and won’t be overworked. What do you think?
Don't turn the CPU fan off—it's a bad move. Keep it running as is. The GPU won't need any fan control because its heatsink handles heat well during idle or light gaming. Installing a game demands significant CPU power, so the system isn't designed to be overworked. It's not like a car engine spinning at full speed. With a stock CPU, five years is plenty. Many people still have i7-4770K units 10 years ago, and your 7700 should last another 12 to 15 years. You're safe.
Well, if you adjust your perspective, I believe in you. With that profile picture, it really boosts my confidence, too. I’ve always seen CPU temperature and clock speed as an engine—rev it higher for longer, and you risk more damage over time! For your NH-U12A chromax.black, I’d recommend a cooler like the Noctua NH-U12A chromax.black in the future.
No worries, it's not quite a car engine. Still, an engine has a redline and staying within the operating range will prevent any harm if it's kept properly. The NH-U12A chromax.black is a great CPU cooler, though it comes at a higher price. I strongly recommend the Peerless Assassin 120 SE—it's only $39 and performs well alongside the NH-D15. The new Deepcool ASSASSIN IV just came out a couple of days ago and it's one of the most attractive air coolers I've ever seen, and it really works!
