Description

Current code only supports Linux. Nowadays it should be trivial (eg. looking at Hashcat code) to replace/add code that works with Windows as well. I don't have (and don't want) access to any Windows gear to test with so we'd need someone else to implement this.

This is not just a cosmetical "nice to have": In some situations the thermal watchdog can really protect user from eg. $1000 loss of hardware due to poor drivers/runtimes not controlling fan speed properly, or insufficient cooling. So ideally we should implement this before Jumbo-2.

Research direction

Inspect the existing Linux GPU sensor support and compare it with the Windows approach used by Hashcat, as suggested in the issue. Test on Windows hardware and confirm that the thermal watchdog receives GPU sensor data; the issue provides no specific files or tests.
