About this tag
Thermal diagnostics on WindowsForum.com currently focuses on monitoring NVIDIA GeForce Blackwell GPU behavior in Windows 10 and Windows 11. The featured IBHE 2.1 utility can enable and log hotspot telemetry when available, while also showing calculated Estimated Cooling Target and Cooling Envelope values. This information can help identify repeatable thermal changes and compare behavior over time, with CSV logging available for further review. The tag’s coverage emphasizes distinguishing directly measured data from estimates and using an administrator account when required. A single temperature reading should not be treated as proof that a cooler, thermal paste, or GPU is defective.
