Why is my PA120 SE screaming but CPU still overheating in GTA V?
In the heart of Los Santos RP, my CPU loads were spiking between 88-94℃, hitting the thermal wall and tanking my frame rate from 110 FPS down to a choppy 42 FPS. Even with the beefy dual-tower setup of the Thermalright PA120 SE ARGB, I was dealing with a nasty heat island effect inside my closed case. I initially tried just cranking the fans to 1800 RPM, but it was a nightmare—the noise was unbearable and I only saw a measly 2℃ drop. After rethinking my airflow, I flipped the front fans to intake and the rear to aggressive exhaust, then tweaked the PWM curve in BIOS to kick into aggressive mode at 75℃. Monitoring via HWMonitor, the core temps finally settled from the danger zone of 92-96℃ down to a comfortable 68-74℃, and frame times stabilized from 12-28ms to a rock steady 8-11ms. I actually realized later that I'd applied way too much thermal paste during the first build, creating tiny air gaps; after a second teardown and a fresh, even spread, the temps finally behaved. Now the noise stays around 32-38 dB, which is way more tolerable. I've saved these voltage offset parameters in the BIOS to keep it locked in.
