My PCcooler RT500 is hitting heat soak and dropping frames during stealth combat in MGS Delta; do I need more intake?

Whenever I get ambushed by a group of enemies, the screen starts to hitch, which is a total immersion killer in a stealth game. Since the PCcooler RT500 TC ARGB is a compact cooler, it really struggles with heat buildup at the base under heavy loads, pushing CPU temps into the 82-90℃ range and causing the clock to dip. I tried the 'Ultimate Performance' power plan first, but getting a measly 2 FPS increase proved that this was a physical cooling bottleneck, not a software one. I jumped into the BIOS and pushed the fan speed limit to 100%, then added two high-static pressure intake fans to the front of the chassis. Monitoring with RTSS showed the frame times shifting from a jittery 16-32ms to a smooth 13-16ms. There was some weird air turbulence noise at first, but I fixed that by slightly adjusting the angle of the fans. CPU temps have settled into the 75-81℃ range. Final stress tests confirm the thermal parameters are now validated and stable.
