How to fix Thermalright PA120 V3 fan lag in Horizon Online?
During massive raids with hundreds of players, I started noticing these tiny hitches that are absolutely lethal when you need precision timing. Monitoring showed that the Thermalright PA120 V3 dual-tower cooler had a 3-second lag in ramping up fan speeds during sudden loads, causing CPU temps to swing between 70-88℃ and triggering clock fluctuations. I tried the High Performance power plan first, but that just raised the base clock without fixing the thermal lag—completely the wrong approach. I went into the motherboard fan control and slashed the fan response time from 3.0 seconds down to 0.1 seconds and enabled Sync Boost. In the RTSS frame time graph, the gaps that were swinging between 14-30ms tightened up to 9-15ms. I did have some annoying fan RPM jumping during low loads at first, but setting a 5℃ hysteresis interval made it quiet again. CPU temps are now stable at 62-70℃. 3DMark stress tests confirm the performance is solid.
