If anyone has any objections, please let me know. ------------------ From: Stephan Gerhold [ Upstream commit 5ba21fa11f473c9827f378ace8c9f983de9e0287 ] Unlike the CPU, the GPU does not throttle its speed automatically when it reaches high temperatures. With certain high GPU loads it is possible to reach the critical hardware shutdown temperature of 120°C, endangering the hardware and making it impossible to run certain applications. Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed when reaching 95°C and polling every 200ms.
