Why is my AK620 White struggling with BioShock 4 loads?
During intense firefights, my core temps were jumping wildly between 88°C and 94°C, which sent my frame rate plummeting from 90 FPS down to a stuttery 42 FPS. The default fan curve on the Deepcool AK620 White ARGB was way too sluggish before hitting 75°C, letting heat soak into the cores faster than the fans could react—it was a total nightmare. I initially tried switching to the High Performance power plan in Windows, but that was a waste of time; it didn't stabilize the clocks and actually bumped my idle temps up by 8°C. I eventually dove into the BIOS, swapped the fan control to Manual, and cranked the slope for the 70°C to 85°C range by 15% per degree. Checking HWiNFO, the peak temps finally settled between 78°C and 83°C, and the clock jitter dropped to under 0.2GHz. I did try maxing the fans at 100% at first, but the low-frequency resonance made my whole chassis vibrate, so I capped them at 1800 RPM to keep things quiet. VRM temps stayed steady at 62°C to 67°C. The thermal throttling is gone, and the curve is locked in.
