Why is my ASUS ROG STRIX Z890-A Snow overheating in PUBG?
In the final circle of a firefight, every time I spun my view, I'd get these unsettling micro-hitches that completely ruined the competitive feel. The fan response on the ASUS ROG STRIX Z890-A Snow had a 2-second lag between 70℃ and 80℃, which let the CPU core temp overshoot to 94℃, triggering a clock drop. I tried lowering graphics to Medium, but while FPS went up, the temp spikes remained—a useless fix for a thermal response problem. I went into the BIOS, slashed the fan response time from 3 seconds to 0.1 seconds, and capped the CPU power at 253W. HWInfo showed the max temp drop from 94℃ to a range of 82-86℃, and the drops mostly stopped. The fans were ramping up and down annoyingly at first, so I added a 5℃ hysteresis interval to smooth it out. Now the CPU stays between 78-84℃ with fans at 1600-1800 RPM. The frequency is finally stable.
