Why is my Jonsbo CR-1400 ARGB throttling in Elden Ring?
During intense Boss fights, my frame rate would suddenly tank from 60 FPS down to 38 FPS, and those unpredictable stutters completely messed up my dodge timing. The default fan curve on the Jonsbo CR-1400 ARGB is way too conservative before hitting 80°C, causing CPU core temps to swing wildly between 92°C and 96°C. I first tried enabling power-saving mode in Windows to cut the heat, but while it dropped the temp by 3°C, my 1% lows plummeted to 25 FPS, which was a total waste of time. I eventually dove into the BIOS and slashed the fan step response time from 2 seconds to 0.1 seconds, while forcing the RPM to 90% once it hits 75°C. Monitoring via HWiNFO showed core temps dropping from 96°C to a stable 78-82°C, and frame times stabilized from a messy 18-32ms down to 12-16ms. I did hit a snag where the fans started vibrating like crazy at max speed, but tweaking the 95°C+ ceiling back to 85% fixed the resonance. Now VRM temps sit around 62-68°C and the noise is tolerable. After two hours of stress testing, the throttling is gone and fans are steady at 1400-1600RPM.
