| # This script runs in the background and checks the temp of my 3060 and 3090 cards. | |
| # The concept is to cut voltage when approaching a thermal limit. This "smoothes out" | |
| # the usage compared to native thermal throttling. This is useful for long sessions | |
| # of Stable Diffusion or heavy chat models. You may need to tune for your own setup, | |
| # temperature preferences, and so on. This is provided with ZERO WARRANTY, so your | |
| # mileage may vary. In general, you should not do magic you do not understand. | |
