My game freezes for half a second during late-game turns in Civ 7. Is this a Jonsbo CR-1400 issue?

Every time the game hits the late-game stage with massive city simulations, the screen just freezes for about 0.5 seconds. It was driving me crazy. The Jonsbo CR-1400 ARGB Black Edition has a default curve that only hits 1200 RPM before 75℃, which is a joke for the bursty power draws of a 14th Gen CPU. I tried the 'Ultimate Performance' power plan, but that just spiked the power draw and sent my temps screaming toward the 98℃ redline—absolute nightmare. I ended up going into the BIOS, switching to Manual mode, and forcing the 70℃ threshold to hit 2000-2200 RPM. Now, the monitoring panel shows cores staying between 76-81℃ under load, and frame times dropped from a wild 18-40ms to a stable 11-16ms. I had some resonance noise at first because the start-up voltage was too low, but a tweak to 1.1V fixed it. CPU package power is now stable at 65-75 Watts. The input lag is gone and the game finally feels snappy. Still, this cooler is definitely pushed to its limit here.
