How to stop thermal throttling with Jonsbo CR-1400 in WoW?
The white aesthetic of this cooler is great, but its performance in raids is a joke. Temps were swinging wildly between 70℃ and 95℃, and my frame rate was bouncing right along with them. The default curve on the Jonsbo CR-1400 ARGB is way too lazy below 80℃, causing the clock speeds to jitter between 3.2GHz and 4.5GHz, which pushed frame times up to 40ms. I tried popping the side panel off my case; it dropped the temp by 3℃ but turned my PC into a dust magnet and sounded like a lawnmower—totally ridiculous. I eventually went into the BIOS and set a steep fan curve: as soon as it hits 75℃, the fans ramp up to 100%, and I optimized the front intake. In RTSS, the frame time jitter dropped from 15-45ms to a smooth 12-18ms. I did notice the fans 'hunting' or surging around 60℃ at first, but adding a 2-second step-up delay smoothed it out. CPU package power now stays at 105-120W, and the fans are steady at 1400-1600 RPM.
