Once installed you'll need to mess around with different CPU Cache and Core offsets to find a balance that works for you. This video is a great guide to not only installing the software but also how to configure it. This program will allow you to adjust your power output to your CPU and Turbo boost clock speeds. I recommend this video for systems with newer Intel processers, if yours is 9th gen or older then you may not need this step. But you can get around this in the BIOS, which is essentially the firmware that boots up your operating system. Intel banned undervolting in their 10th gen processors due to a hike in plundervolting (a technique that allows users to work around manufacturer settings by dropping power so low the processor overlooks security measures). To undervolt you first need to unlock undervolting in your systems BIOS. Thermal issues in MSI laptops primarily affect the CPU, and this tool does wonders for it. By decreasing the parts power consumption, it reduces the heat that can be generated. Undervolting is the process of manually reducing the power output to your CPU without seriously impacting performance. I am leading with undervolting because it will likely have the single greatest impact on CPU temps of any of the techniques I will list here. There are far more ways to optimize performance than just in-game settings, these include reducing power output to temperature sensitive hardware, reducing non-game related processes, assigning certain work loads to computer parts that can handle more temp, and more that I'll get into below. Reducing the number of calculations / commands your hardware needs to process decreases the amount of power running through them, thus decreasing their temperature. Everyone in PC gaming has done this to some degree, whether it be changing your graphics settings or lowering your resolution. Assuming hardware changes are unavailable, the best way to do this is change the work load your putting on your CPU / GPU. This means finding ways to manually alter GPU / CPU temps and clock speeds (clock speeds /engine clock refer to the speed at which your CPU and GPU operate, essentially their performance output). In its most basic form, performance optimization is about getting your computer to output the best performance without exceeding dangerous temperatures. Avoid this at all costs, your C/GPU are running at dangerously high temps, and performance is suffering because of it, its the worst of both worlds. This is called thermal throttling, and means your computer parts are running so hot, they cannot operate properly. Issues arise when the computer demands a level of performance that creates temperatures greater than the cooling system can suitably dissipate. For most laptops its a set of fans that pull cool air in and push hot air out. To deal with these high temps, all computers have built in cooling systems. This generally isn't an issue as the parts are designed with these fluctuations in mind, and can reach temps of about 75-80C (this figure will vary depending who you ask) before regular use causes permanent damage to the hardware. In computers, hardware performance and hardware temperatures are directly related, the more performance from your CPU and GPU, the hotter they will get. For this reason this guide will focus largely on C/GPU optimization as it will lead to the greatest performance difference. People will talk about RAM, and SSD's over Hard drives and while these are important, and can throttle performance if aren't up to spec of the C/GPU, they don't suffer from overheating, and there are very limited options to optimize. The vast majority of gaming performance comes from your Central Processing Unit (CPU) and your Graphics Processing Unit (GPU). I'm sure many of you will have seen some of these techniques before, and if you have techniques that I didn't list please feel free to mention them. I'm treating this as guide for users of all levels of technical understanding, so if you're already familiar with the basics and are looking for the details, skip down a few paragraphs. I spent a few weeks optimizing my laptop to run the best frames at a safe temp, this is my experience with maximizing performance and minimizing temps. This was usually manageable as most of the games I play are less computationally intensive, but a few weeks ago I decided I wanted to try "Star Citizen", a very graphically dense game. I have an MSI GS66 stealth (i7-10875H, RTX 2060, 16GB RAM), Its a wonderful laptop but like many other MSI owners, I ran into serious CPU overheating issues, with it often reaching 95C or higher when at max performance.
