They are correct and you should trust them. If you reach 80°C then you probably need better thermal dissipation or a different CPU / graphics power management strategy. For example you can blacklist the highest performance level of the CPU and/or GPU. Adding a fan which only kicks in at high temperatures would also make sense if your case and board support that. If AMD CPUs have an equivalent of Intel's "turbo mode" then you should disable that. BTW, you may have other (unsupported) sensors on the board... Give a try to http://dl.lm-sensors.org/lm-sensors/files/sensors-detect and report the full output. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
