How to fix case airflow blockage and CPU overheating in TEKKEN 8?

During TEKKEN 8 versus matches, my Jonsbo CR-1000MAX Standard Edition case airflow was blocked. The CPU temperature spiked from 70°C to 90°C, causing the frame rate to drop from 144 FPS to 100 FPS. I first tried opening the side panel, but found severe dust accumulation, which was a frustrating physical problem. I then used the GamePP Fan Curve Configuration tool to increase the front fan to 1500 RPM and the rear fan to 1800 RPM. This created strong negative pressure. After balancing to 1200 RPM to reduce noise, I ran an AIDA64 stress test. The CPU temperature converged from 90°C to 75-78°C. This fix resolved the thermal bottleneck and restored stable frame rates for competitive play.
