Package: intel-microcode Version: 3.20191115.1 Severity: important
Hi. With the most recent upgrade, the CPU seems to run at considerably higher temperatures. Shortly after a fresh boot, but long enough so that everything has started up, and the system being basically idle it looks like this: microcode updated early to revision 0xca, date = 2019-09-26 iwlwifi-virtual-0 Adapter: Virtual device temp1: N/A coretemp-isa-0000 Adapter: ISA adapter Package id 0: +58.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +57.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +57.0°C (high = +100.0°C, crit = +100.0°C) CMB1-acpi-0 Adapter: ACPI interface in0: 16.60 V curr1: 0.00 A And with the same kernel but older microcode: microcode updated early to revision 0xc6, date = 2019-08-14 iwlwifi-virtual-0 Adapter: Virtual device temp1: N/A coretemp-isa-0000 Adapter: ISA adapter Package id 0: +55.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +53.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +54.0°C (high = +100.0°C, crit = +100.0°C) CMB1-acpi-0 Adapter: ACPI interface in0: 16.60 V curr1: 0.00 A top shows basically no CPU utilisation (in both cases) but the fan goes up and the CPU is constantly notacibly hot, which both wasn't the case previously when the system was idle. Now another strange thing: With the NEW microcode, once some load was put on the system, even when this is gone and the CPU back to basically no utilisation, the temperatures are at a *much* higher level and stay there, for whichever reason: iwlwifi-virtual-0 Adapter: Virtual device temp1: +34.0°C coretemp-isa-0000 Adapter: ISA adapter Package id 0: +76.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +70.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +69.0°C (high = +100.0°C, crit = +100.0°C) CMB1-acpi-0 Adapter: ACPI interface in0: 16.59 V curr1: 0.00 A Is this a problem with the microcode or a kinda expected side-effect of the security workarounds?
