Thank you for your comment. I installed thermald on my Lenovo T480 with Debian Bookworm and I get 20% better results in stress-ng. The fans are a bit louder now under high load and off under low load. Without thermald: $ stress-ng --matrix 0 -t 3m --metrics-brief stress-ng: info: [3755113] setting to a 180 second (3 mins, 0.00 secs) run per stressor stress-ng: info: [3755113] dispatching hogs: 8 matrix stress-ng: info: [3755113] stressor bogo ops real time usr time sys time bogo ops/s bogo ops/s stress-ng: info: [3755113] (secs) (secs) (secs) (real time) (usr+sys time) stress-ng: info: [3755113] matrix 2278812 180.00 1437.43 0.27 12660.06 1585.04 With thermald: $ stress-ng --matrix 0 -t 3m --metrics-brief stress-ng: info: [3755550] setting to a 180 second (3 mins, 0.00 secs) run per stressor stress-ng: info: [3755550] dispatching hogs: 8 matrix stress-ng: info: [3755550] stressor bogo ops real time usr time sys time bogo ops/s bogo ops/s stress-ng: info: [3755550] (secs) (secs) (secs) (real time) (usr+sys time) stress-ng: info: [3755550] matrix 2791272 180.00 1404.32 0.57 15507.06 1986.83 I just installed it using apt and did no extra configuration. My system was anyway configured for balanced power mode. Why is thermald not installed on desktop installations by default?
