How to stop Seagate FireCuda 540 2TB from overheating?

Watching my frame rate tank from 120 down to 35 FPS was an absolute disaster; it felt like I was trying to walk through waist-deep mud. Looking at the telemetry, while the FireCuda 540's cache is great for response, the PCIe 4.0 power draw pushed core temps to a scorching 82-88℃, triggering a hard hardware throttle. I tried capping the interface to PCIe 3.0 in the BIOS, which dropped temps to 60℃ but slaughtered my load speeds by 40%—totally unacceptable. I ended up swapping in a 2.0mm high-conductivity thermal pad and locked my bottom chassis fans to 1800 RPM. HWInfo now shows the drive pinned between 62-67℃, and the drops are gone. I actually messed up the installation at first and slightly bent a pin on the connector, so the drive didn't post on the first boot, but a quick reseat fixed it. Sequential reads are now hitting 6500-7000MB/s. After a 4-hour stress test, the performance is rock solid and memory temps are sitting at 58-63℃.
