How to stop CPU throttling in Horizon Online with RT500 TC?
Cruising through the open world was great until my frames suddenly tanked from 110 down to 45, and that stuttering was a total nightmare. The heat pipes on the PCCOOLER RT500 TC ARGB just couldn't keep up with the sudden power spikes, causing my P-Cores to jump wildly between 88-96℃. I first tried slamming the fans to full speed in the BIOS, which only dropped the temp by 4℃ but created a high-pitched whine that made the game unbearable. I eventually built a non-linear PWM curve using third-party software, setting a steep ramp-up between 75℃-85℃ and hitting max RPM at 90℃. Checking HWiNFO, the core temps finally settled into a tight 72-78℃ range, and my frame times stabilized at 8-12ms. I actually hit a snag during the first tweak where a too-small step value caused the fans to vibrate, but adding a 2-second hysteresis delay fixed it. With the CPU pulling 145-160W, the cooling is finally balanced. It's a bit of a hassle to maintain, but the stability is worth it.
