Issues with heat and clock functionality on 12700H devices
Hello! I acquired a Lenovo IdeaPad Gaming 3i equipped with an i7-12700H processor. I’m generally satisfied so far, but I’m experiencing heat, fan noise, and idle performance concerns. Here’s a bit of background: After installing a fresh Windows 11, I addressed some initial overheating issues by reapplying the case. Still, two main problems remain. First, when the laptop sits on the desk and the lid is closed, it becomes quite warm. The fan runs at low or medium speed, yet there’s noticeable heat buildup. It should be idle or in sleep mode, but that doesn’t happen. Opening the lid brings things down. Second, every core appears stuck at a high frequency with minimal or no activity. I took screenshots from HWMonitor while downloading a game via Epic Launcher. One core is hovering around 15% utilization, while others are near zero, yet all remain locked at very high clock speeds and temperatures. While the 3050ti can handle good temps when pushed, overall it feels excessively hot—even simple tasks like typing with just one Chrome tab cause my hands to warm up. I’m unsure what’s typical for a non-Mac laptop, but this definitely doesn’t seem right. This is part of several similar troubles I’ve faced trying to get a functional Windows machine. Help needed!
You might also want to check background tasks in Task Manager. From personal experience, antivirus scanning every five minutes even though it follows a schedule or runs third-party software when it shouldn't or at startup. >>If yes, right-click the item in Task Manager > go to file location > create a new folder> move the executable there> and if you need to use it again, add a shortcut to the desktop. Be careful not to affect essential Windows processes. You could also compress the entire folder (.zip or .rar) if it still starts on its own.
Some laptops might activate "High Performance Mode" under certain conditions. This behavior can be confusing, so here are a few suggestions:
1. Consider adjusting the Core Boost setting. Many users prefer a balanced performance rather than maximum output at all costs. You can find advanced registry options like "Processor Performance Mode" or "Agressive mode" to fine-tune settings and see what suits you best.
2. Another useful setting is "Core Parking." Modifying this can improve thermal management. On my machine, lowering the percentage (e.g., to 0%) allows more cores to enter a low-power state while still maintaining performance.
3. The system's cooling policy often defaults to active mode. Switching it to passive mode can help regulate temperatures by gradually reducing CPU speed and boosting fan speed when needed.
Regarding your concerns:
- Have you checked for BIOS updates? Updates can resolve temperature-related problems and improve fan behavior.
- If heat is a recurring issue, verify that the fan is properly connected and functioning correctly.
- Ensure the heatsink was installed correctly with adequate pressure—sometimes a slight adjustment makes a big difference.
- You might want to try different power settings configurations to observe how they affect performance and cooling.
I recommend experimenting with these adjustments and let me know how it goes! Keep this advice in mind for your setup.
