What Is the GeForce Hot Fix Driver?
Hot Fix drivers are NVIDIA’s way of releasing rapid updates outside of the regular Game Ready or Studio Driver cycles. They aim to quickly resolve high-priority bugs that can impact performance or stability for gamers and professionals alike.
This latest GeForce Hot Fix Driver addresses a GPU temperature reporting bug that led to inconsistent or inaccurate temperature readings on some RTX GPUs—especially when using third-party monitoring tools.
The GPU Temperature Reporting Bug Explained
Recently, users began noticing that their GPU temperature readings were either abnormally low or fluctuating erratically during idle or low-load conditions. This wasn't just cosmetic—it made it harder for users to manage thermals or detect real overheating issues.
