The CPU begins throttling shortly after powering on, and the exhaust vents aren't producing much heat. This pattern appears consistently during testing. The cause could be related to cooling issues or thermal throttling behavior. To resolve it, check the cooling system, clean dust from fans and vents, or consider upgrading the cooling solution.
It seems the Intel ARK page lists a 45W TDP and a max temp of 100°C, which matches well. Performance runs at 3.5 GHz boosted across all cores, and it's also operating at full capacity. How often does your CPU stay under 100% load? If the laptop is several years old, cleaning it might be beneficial.
It's a Lenovo Legion Y540 that's been around for about a year. I cleaned it gently, but there wasn't a lot of dust inside. It gets used a lot for demanding work.
This device is from 2018 and isn't brand new. The Y540 handles a 9300f well despite lacking strong cooling. Because it's old, replacing the thermal paste might be necessary. Dust accumulation is common inside the heatsink area where the fan operates, creating a buildup that restricts performance. If the mat becomes too thick, removing the fan could be required to clear it.
You require powerful airflow for this setup. A PC vacuum (blower) costs around $30 and should suffice. For thermal paste, I stick with the reliable Arctic MX4.
Sure its a bit of a weirder substance and harder to spread but will work. Fyi with laptops you need to 100% cover the die with paste. Basically spread it out with a plastic card and then add a dot or 2 on top of that. Thisnis because there is a lot less mounting pressure since its direct die contact. Since you need to remove the heatsink anyway a paintbrush + balloonpump will do to remove dust.
