GeForce RTX 50 Cards Regain Hotspot Temperature Monitoring with HWMonitor Update

• July 19, 2026

Users of Nvidia’s GeForce RTX 50 series graphics cards can once again monitor the critical hotspot temperature data thanks to a recent update to the HWMonitor utility. Version 1.65 of the popular hardware monitoring tool has restored the ability to track the temperature of the hottest point on the GPU die, information that had been inaccessible to third-party applications.

Access to Hotspot Temperature Returns

The hotspot temperature is an important metric for enthusiasts and professionals who want detailed insight into their GPU’s thermal conditions. Despite Nvidia including the related sensor within its latest Blackwell architecture GPUs, the company had effectively blocked third-party software from accessing the readings, leaving users without visibility into this key thermal data.

The new HWMonitor update circumvents this limitation by unlocking access to the sensor data, enabling users to monitor the precise temperature of the GPU’s most heat-stressed area. This development is particularly relevant as it confirms that Nvidia did not physically remove or disable the thermal sensor but only restricted software from reading its output.

Prior to this, users and monitoring tools could typically only rely on the GPU’s general temperature readings, which do not always reflect the hottest spots on the chip. The hotspot sensor provides a more granular measure, allowing for better thermal management and diagnostics.

With HWMonitor’s enhanced support, users can now obtain more accurate thermal information to optimize cooling solutions or troubleshoot performance issues on their RTX 50 series hardware. This could be valuable for both gamers and professionals relying on these GPUs in demanding workloads.

Details about Nvidia’s choice to block hotspot temperature visibility have not been formally addressed, and the company has not released statements regarding the sensor’s accessibility. Nonetheless, the presence of the sensor in the hardware and the ability to read its data through updated software has been verified.

HWMonitor remains a widely used utility for monitoring a variety of system sensors, including voltages, fan speeds, and temperatures. Its support for unlocking previously hidden sensor data marks a notable update for GeForce RTX 50 owners seeking comprehensive system monitoring capabilities.

Pricing and availability for HWMonitor version 1.65 and its specific features were not disclosed.
