Disabled turbo boost prevents the throttle from engaging.
Disabled turbo boost prevents the throttle from engaging.
you're dealing with a MSI GF75 9SC thin laptop that has an i7-9750h processor. your system runs at 2.60ghz base and 4.50ghz turbo boost. when playing demanding games like nfs heat, ac odyssey, or far cry new dawn, your cpu temperature spikes to 90-100°C even at low usage (70%). sometimes it goes up to 27% even with minimal load. the fans spin at 6k rpm, but the issue persists. your friend suggested using throttle stop software, which you've already disabled by setting turbo boost to base speed and limiting it to 70-85%.
what you're doing is correct, but you might want to check if your cooling system is still adequate for such high loads. ensure the case vents are clear, dust is removed, and consider upgrading the cooling solution if needed. also, verify that your power supply can handle the increased load. if the problem continues, it could be related to thermal paste degradation or internal component stress.
Not a whole lot you can do to help cooling on a laptop, but changing to a better thermal compound will probably help some. Be careful though, doing so may void your warranty. Linus has a video showing a significant improvement by changing to liquid metal, but if it was my laptop I would stick to a high quality non conductive paste like MX4. That will also help because you may be able to undervolt the CPU more if it it runs cooler. The cooler the CPU runs, the less voltage it needs. Run the minimum voltage you can, less voltage means less heat.
there are various accessories like laptop cooling bases with fans beneath your machine. these are often affordable online. however, it’s important to note that laptops aren’t ideal for prolonged hard gaming sessions. they’re better suited for casual play—such as 30 minutes a day—compared to desktop PCs, which typically have metal heatsinks and dedicated cooling solutions for intense use.
Ensure the CPU is present and, if needed, replace the separate heatsink. For items outside warranty, a professional repairer is best—they’re skilled and careful. Check if the cooling fan operates; dust buildup could block it. A vacuum on the air intake might clear debris but won’t affect throttling. On Windows 10, power management limits CPU usage around 75% or less.
The issue isn't something you can fix. Your laptop's cooling system is completely failing. Consider getting a new PC.
My new laptop has no dust buildup, GPU temperature stays around 70°C during games, and CPU usage rarely reaches 75%. At 27% CPU load, temperatures still climb past 90°C since it's running at high speeds. Thanks!
