Dealing with Jonsbo CR-1400E heat saturation in Remnant 2
During high-intensity Boss fights, my frame rate would start a slow, painful slide after about an hour of play. Monitoring showed the aluminum fins on the Jonsbo CR-1400E ARGB were hitting total heat saturation, causing core temps to creep up from 75℃ to 88-92℃. I tried lowering the global illumination in-game, which gave me a measly 3 FPS boost but did nothing for the heat—it proved this was a physical cooling bottleneck. I ended up reworking the case airflow, switching the rear fan to a high-pressure exhaust and dropping the CPU fan trigger threshold to 50℃. In CPU-Z stress tests, the core stayed between 78-83℃ even after two hours, and the frame drops vanished. I had some annoying wind noise after the first tweak, but dialing the fans to 1200 RPM fixed it. CPU usage is now evenly spread with no throttling, and RAM temps are holding at 58-63℃.
