NVIDIA's newly launched GeForce RTX 50 series graphics cards have disabled API support for hotspot temperature monitoring at the software or driver level. This move restricts mainstream hardware monitoring tools from accessing this vital parameter. The hotspot temperature, which indicates the hottest point on the chip, is essential for diagnosing cooling-related issues. Although NVIDIA only officially offers readings for the average GPU temperature and VRAM temperature, tech-savvy individuals have managed to unlock hotspot temperature monitoring through technical methods, confirming that the sensors are still physically present on the hardware. Tests show that when the average GPU temperature climbs to 70 - 80℃, the hotspot temperature can soar to 107℃. This can trigger thermal throttling and negatively affect performance. It implies that depending solely on the average GPU temperature readings may not accurately reflect the actual risks of localized overheating, potentially leading to long-term hardware damage. Recently, with the release of CPUID's HWMonitor 1.65, hotspot temperature reading capabilities for RTX 50 series graphics cards have been restored, offering users more comprehensive monitoring information.
