Intel Revises PCIe Cooling Driver To Reduce Link Speed When Running Too Hot

Since last year Intel's open-source software engineers have been working on a PCIe bandwidth controller driver for the Linux kernel to avoid thermal issues by being able to automatically reduce the PCIe link speed when needed

The driver will register a cooling device for each PCIe port discovered where the link speed can be manipulated. Given this "pcie_cooling" thermal driver has been in development since last summer already, hopefully it finds its way soon to the mainline kernel.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
