How to stop Jonsbo CR-1400 from throttling in Planetside?
In the middle of a massive firefight, my CPU temps would slowly but surely climb from 70℃ to 95℃, which dragged my clocks down from 4.8GHz to a pathetic 3.2GHz. The CR-1400 is a small cooler, and it just hits heat soak too fast under sustained load, losing about 20% efficiency after 40 minutes. I tried blasting all my case fans at 100%, but that only dropped the ambient temp by 2℃ while the core kept climbing—it was a pretty hopeless feeling. I eventually went into the BIOS and changed the fan curve from linear to exponential, forcing 100% output above 80℃, and optimized the rear exhaust. HWMonitor shows the core now stabilizes between 82-88℃ without hitting the throttle point. The fans were oscillating wildly at 75℃ at first, but adding a 3-second hysteresis timer smoothed it out. CPU power stays around 95-110W, which is the limit for this cooler.
