I am facing overheating and performance lag issues while running data science tasks on my laptop. When using tools like Jupyter Notebook, Python libraries, or large datasets, the system temperature rises quickly and the laptop becomes very slow. Sometimes applications same as web apps like when i play games online like letterboxed it  freeze or crash, which interrupts my workflow. I would like to know if this is a hardware limitation, cooling issue, or if there are recommended performance optimization settings for better stability.

I am using an HP ZBook 15 G4 with 48GB RAM and a 512GB NVMe SSD, mainly for Python development, Jupyter Notebook work, and Morse code translation, audio processing projects. Despite the RAM upgrade, the laptop heats up heavily during workloads and sometimes becomes slow or unresponsive. In some cases, browser-based apps or lightweight online games freeze or crash when the temperature rises.The overheating usually starts when running Python libraries, processing larger datasets, or multitasking with browsers and development tools together. CPU usage spikes quickly and the fans become very loud, but performance still drops after some time. Since the storage and RAM are already upgraded, I want to understand whether this is mainly:a thermal/cooling problem, CPU throttling due to heat, aging thermal paste or dust buildup, power/performance configuration in Windows, or simply a hardware limitation of the laptop under sustained workloads.I would also appreciate recommendations for improving
