Questioni7-7700K è sempre attivo al 100%?
The issues with my old i5 6500 were frequent overheating, especially when running at full capacity. After upgrading to an i7 7700K, the PC started showing similar problems. The CPU would reach 100% for a short time, then cool down but would randomly spike back up to 20% or higher, accompanied by loud fan noise. After about five minutes, it would drop below 10% again. Chrome tabs would cause the CPU to jump to 80% and then quickly return.
I’m wondering what might be causing these fluctuations. Are the Thermalright Peerless Assassin 120 SE V2 fans too noisy? Or is my cooler just getting used to the new setup? Also, are the "Cores 2 and Logical Processors 4" specs accurate?
The fan temperatures on Chrome kept rising from 35 to 60 degrees and then decreasing. The fans became louder during spikes and quieter afterward.
I’m currently idle but the CPU would hit 100% again, with temperatures reaching 66 degrees. It then dropped back to 15% and 38 degrees. During a game, my CPU kept maxing out at 100%.

Update your post with complete hardware details and operating system information. Provide the power supply specifications, including voltage, amperage, age, and condition (original, build, refurbished, used). List the disk drive specifications such as make, model, and capacity, along with their current usage. Include a list of all connected peripherals. Specify whether the network connection is wired or wireless.
Do you have a tool that helps display specifications clearly?
Speccy, HWiNFO, CPU-Z, Belarc Adviser can be used to collect information. Also, right-clicking the window in the lower left corner reveals a "Run" option. Click it and a window appears. A box labeled "Open:" should be filled with "msinfo32" and then "OK". This will generate a system summary, though it may not contain all needed details for initial use. Check recent posts for more examples. The essentials are usually listed on the PC's specifications sheet at purchase.
It isn't surprising that you're not noticing a significant improvement. Switching from an i5-6500 to an i7-7700K doesn't prevent Windows from utilizing the full processing capacity when required. To truly experience any advantage, a system with more CPU cores would be necessary.

In summary, both your processors are essentially four-core units, and the 7700K does offer HyperThreading which provides a modest boost. I view these extra threads as delivering around 30% of the performance of a single core on average.
The i7-4770K I have tends to run at high CPU utilization across all four threads with 8 threads, whereas my 16-core 32-thread 7950X handles similar tasks with ease, such as installing Windows updates.
Your situation mirrors mine with the i7-4770K. It often takes close to two minutes for the Windows desktop to load after booting from an M.2 NVMe drive, since the system is checking multiple SSDs and slower hard drives.
On my machines, Windows and other applications then search for updates. After a few minutes, things stabilize. This behavior is completely typical for an older PC connected to the internet.
For testing purposes, disconnect your PC from the network and observe the boot time. It may be slightly faster, as update checks fail, which is normal for an older machine.
To experiment further, unplug your PC from the internet and watch how long it takes to start Windows and complete initial setup. You might notice a reduction in time, since update verification slows down.
The timing of fan speeds in the BIOS affects performance. Some systems allow choosing between Full, Turbo, Normal, or Quiet profiles, but I prefer manually adjusting them for optimal temperatures and fan settings.
If your BIOS settings push fans to their maximum, you'll hear louder fans and experience slightly cooler CPU temps. This shouldn't be a major concern, as it's just a matter of managing heat.
The i7-7700K can operate comfortably up to +100°C, but at that point it may reduce performance to protect itself. I often run my 7950X at around 80°C in the mid-eighties for extended periods. Some cores reach +95°C, which is AMD's safe operating limit.
This is entirely normal for older hardware. If you play the same game with identical settings on a newer machine like the 9800X3D, performance drops will be minimal.
Your CPU and GPU might simply not be powerful enough for certain games. Lowering the screen resolution or disabling unnecessary background tasks can help reduce CPU load. However, results may vary depending on the game's demands.
Your i7-7700K is a 7th-generation Intel chip from early 2017, which is an improvement over my 4th-gen 4770K, but Intel's 14th-gen processors have been available for years. Upgrading to a newer generation would help, though it's not the best time to purchase DDR5 memory.
TLDR: Focus less on temperatures, fan speeds, and absolute CPU usage numbers.
I value the effort you put into your answer; it really clarifies things. I’ve observed a noticeable improvement in gaming performance with the new CPU, compared to my previous setup where I frequently hit 20-40fps on ARC raiders. Recently, using the updated CPU, I’m achieving 80-90 FPS without any stuttering.
Regarding the CPU cooler, it has transitioned from slow to high RPM and produces noticeable noise even during simple actions like opening a new Chrome tab. After a short pause, it settles down. I’m wondering if adjusting the fan speeds in the BIOS could prevent this excessive noise. Given my Gigabyte motherboard, which is fairly old, I suspect the current settings might be too aggressive.
In the BIOS, when I set the fans to manual mode, I can adjust the speed on a graph for temperature and CPU temps. Is there a way to fine-tune these so the fans stop activating abruptly? I’m concerned that if the fans don’t engage properly, the system might idle at higher temperatures.
I tried experimenting with these settings recently and believe I may have worsened the situation—now the fans are cycling on and off irregularly. The maximum temperature I observed during a game was around 72–78°C. Any suggestions on how to stabilize the CPU cooler’s RPM?
It is incorrect. A 7700K features 4 cores and 8 logical processors. Run msconfig, clear the Number of processors box and reboot. This will enable Windows to recognize the remaining CPU components. You must perform this action when upgrading to a processor with more cores and logical processors than before.
I wouldn't say "competely avoid" but you should be able to modify your agressive fan speed profile by setting the curve so the fan speeds up more gradually. The only "negative" side of running your CPU cooler fan(s) slower is the CPU will get hotter. Some people get worried about high CPU temperatures. Some people hate loud fan noise. I'm probably unusual because I tolerate both high CPU temperatures and loud fan noise, but I come from an engineering background and I've worked in large, very noisy server halls. Modern Intel CPUs are designed to run up to +100°C. Modern AMD CPUs are designed to run up to +89°C, +90 °C or +95°C (depending on model). My old Phenom II X4 965 tops out at only +60°C. How things have changed! Hot is now "good". When a modern CPU reaches its maximum design temperature, thermal throttling should engage, reducing the clock frequency and preventing the temperature from increasing. It's a bit like bouncing a vehicle's engine off the rev limiter, with the accelerator pinned wide open. I'm not sure how good the thermal over temperature protection is in your older i7-7700K. Caution might be advised. How hot you run your CPU depends on your fan curve settings. If you want a cooler processor, run the fans a bit faster at each point on the curve. If you want lower fan noise, accept somewhat higher CPU temperatures. You have to balance CPU temperature against fan speed. Your decision. Yes. See above. Play around with the fan curves. When running long Topaz Video AI transcodes, my 7950X sits with all 16 cores running in the high seventies, low eighties Centigrade. When I check maximum temperatures in CPUID HWMonitor, a few cores have peaked at +95°C. Your idle temperatures seem a bit high, but that might be due to you not having a big enough cooler and running the fan(s) too slowly. To put things into perspective, I'm running my CPU continuously for many hours at temperatures higher than your maximum of +78°C. I regard this as perfectly normal behaviour for a fairly modern Ryzen system, running as hard as possible to achieve maximum throughput. Now it's possible your CPU might last longer than mine if you keep it nice and cool, but I regard my computers as a tools and I don't molly coddle them. People who play games boast of huge FPS scores and they're probably pushing their CPUs and GPUs hard too.

They're two different readings, explained in the link above. The first is the maximum temperature of the Integrated Heat Sink (IHS). The second is the maximum temperature of the underlying Silicon die. There are plenty of discussions on Tom's and other sites about safe temperatures for the 7700K. https://forums. The link below states anything above +90°C should be avoided on the i7-7700K and i'd recommend you heed this advice. The i7-7700K is an old processor and may not be as robust as a modern design. https://thetechylife.com/how-hot-can-a-i7-7700k-get/ Read through as many i7-7700K reviews as possible and decide what's best for you. Consider +85°C as your top limit. If you're still unhappy with your temperatures and fan speeds, fit a much bigger air cooler with more thermal mass and greater fin surface area, or maybe a large AIO if you can find one to fit LGA1151. I use Noctua (expensive) and Thermalright (inexpensive) coolers in most of my builds. https://www.amazon.com/Thermalright-Roya...B0DNJYFQ4H https://www.amazon.com/Thermalright-Phan...B0BNDTJVPL https://www.amazon.com/Thermalright-Peer...B09LGY38L4 The Royal Praetor, Thermal Assassin and Phantom Spirit coolers are BIG. Check your case dimensions before ordering. Any one of these coolers will be a sound investment (pun intended) and should run quieter. I've also used these SI-100 single fan coolers in low profile media PCs, but the dual tower twin fan Thermalright coolers provide better performance. https://www.amazon.com/Thermalright-SI-1...B0BLBS7TD9 If you're still using the stock Intel cooler on your i7-7700K, throw it into the nearest trash/recycle bin. I have a dozen old Intel coolers sitting unused in a box. OK on a Celeron, but not on a 7700K.
I actually put in a Thermalright Peerless Assassin 120 SE V2 CPU Cooler. After installing the i7 7700k, I downloaded Fan Control and adjusted the fan curves for the CPU fans. When I set the CPU fan to 0%, it still spins at 500 rpm? When I set it to 50%, it's at 1100 rpm, but still 500? Could one of the fans be still running while I installed two with the cooler and its splitter?
I haven't experimented with Fan Control before. The BIOS configurations have consistently sufficed for me, or MSI AfterBurner works well for GPUs. Not an option I'd contemplate for a standard PC fan setup, since: 1). Protection circuits frequently cut power instantly if they sense 0 RPM on the CPU fan connector. They presume the CPU fan has stopped working or been connected to the wrong pin. This is built-in to prevent overheating. 2). Certain fans disregard "impossible" adjustments (such as 0 RPM) and keep spinning at their lowest rated speed. Therefore, when you input 0 in your third-party Fan Control program, the fans seem to have ignored that setting. If the fans use PWM control, they get a steady +12V supply plus a variable square wave signal to regulate speed. The fan controller determines the minimum speed, not your software. In any scenario, a fan operating at around 300 RPM minimum is unlikely to reach a typical 25dBA level, which is almost silent with the case panels installed. Even at 500 RPM, I wouldn't anticipate more than about +27dBm. For details on configuring 0 RPM curves, you can check this link: https://forums. It seems reasonable, but I recommend setting CPU fans to full speed at +85°C or even sooner at +80°C. If my system were affected, I'd increase them to 100% by +70°C, but I don't mind the noise then. Regarding safety, it really depends on how your older i7-7700K performs when the silicon reaches its thermal limit. I'm comfortable pushing a modern Intel CPU beyond the +100°C threshold, though a 2017 chip is another story. The fact that multiple sites suggest a max working temperature of +85°C for this model and warn against going past +90°C makes me wonder if Intel's thermal protection at (likely) +100°C on this 9-year-old build is truly reliable. Do you risk electromigration, particularly when overclocking your CPU? https://www.howtogeek.com/829636/how-ele...-your-cpu/ Please note it took me six years of overclocking an AMD FM2 CPU by 25% from brand new before this occurred. If you're not adjusting the Vcore, it's probably unlikely to happen. Just for humor, try running a demanding game or a short video conversion in Handbrake. Monitor your CPU temperature with the BIOS fan speed set to Max, then with your chosen speeds, and compare the peak temps. If you prefer a quieter system but a hot CPU, that's your decision. If you begin using HWMonitor before each test, it will log both peak core temperatures and average/minimum readings. https://www.cpuid.com/softwares/hwmonitor.html When you connect two fans using a standard splitter cable, the tachometer reading from one fan is cut off. Linking two different tachometer signals into the motherboard would create confusion, so only one fan should be monitored. Given that the motherboard supplies the same voltage and PWM signal to both CPU fans, they should operate similarly, differing by a few percent. However, since only one fan is being watched, you won't know if the unmonitored fan has failed—except for increased noise from the remaining fan and possibly higher temperatures. If you wish to verify both CPU fans are running, open the case and raise the central fan. At low speeds, gently touching the spinning blades shouldn't cause serious damage, though high-speed server fans (10K–30K RPM) can easily cut through your finger. Proceed with care. https://www.delta-fan.com/technology/e-series-fans.html
