After two hours of Indiana Jones and the Great Circle, my RT620P seems to soak up heat and performance dips. Need better airflow?

As the session drags on, the input lag becomes noticeable, especially during stealth segments. The RT620P fins were essentially heat-soaking in my cramped case; temps crept up from 65,0C to 88,0C, which forced my boost clocks to slide from 5,0 GHz down to 4,2 GHz. I tried just cranking the fan speeds, but the noise was unbearable and the temp only dropped by 1,0C—a lesson in not being blind with settings. I reorganized the case pressure to a positive setup and linked the RT620P fans to the motherboard's VRM sensors for better synchronization. HWInfo shows my cores are now stable at 68,0 - 74,0C, and my boost is back above 4,8 GHz. I did hit a snag where the top fans started rattling, but some rubber gaskets fixed the resonance. Fans are now cruising at 1100,0 - 1300,0 RPM. No more clock dips after four hours of testing.
