I started stress-testing the high-performance PC. At 50% to 60% duty cycle, the case fans are somewhat noisy, but the sound profile is tolerable, there's no rattling, the glass near the graphics card is cool to the touch, and the air inside the chassis is ventilated quickly. 🌀
An update on the high-performance PC: the main components and all the NVMe SSDs have been installed. Before I use it for whatever I want, let alone migrate an existing operating system to the primary SSD, I will be stress-testing and validating the system while watching the thermistor readings. 🧑💻
