How to stabilize CPU boost on PCCOOLER RT620 ARGB?
The frame rate swings were brutal in the big city hubs, with a noticeable hitch every few seconds. Looking at the logs, the PCCOOLER RT620 ARGB was letting core temps sit between 88-94°C, meaning the CPU couldn't hold its 5.0 GHz boost for more than a second. This caused the frame times to jump all over the place. My first instinct was to cap the maximum processor state at 99% in Windows, which dropped temps by 10°C but cratered my 1% lows from 55 FPS to 41 FPS—a terrible trade-off. I ended up ripping the cooler off and realized the fans were set to exhaust instead of intake. I flipped them to push air through the fins and reapplied high-end thermal paste using the cross-pattern method. HWMonitor showed core temps plummet from 92°C to a comfortable 72-78°C, and the boost clocks finally stayed put. It was a rookie mistake with the fan orientation causing heat to pool at the top of my case. Now, CPU power draw is stable at around 125 Watts and everything feels buttery smooth, with RAM temps sitting between 58-63°C.
