Computer Temperature

I just realized that my Thinkpad T460p gets really loud. I suspect that there is just quite some dust in the machine so that the fan gets louder. But I'm not sure how to check that and I hesitate to open the machine. So let's see which information I can get form the software.

My System

  • Hardware: Lenovo Thinkpad T460p
  • Software: Ubuntu 18.04
  • Running: Chrome (no videos playing; no Flash), Sublime Text - nothing fancy

CPU Temperture

My room temperature is 24°C, my CPU temperature is roughly 50°C:

sensors
coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +54.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +50.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +54.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +49.0°C  (high = +100.0°C, crit = +100.0°C)

Adapter: Virtual device
temp1:        +34.0°C

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +47.0°C

HDD Temperature

My HDD (a Samsung SSD) is roughly 40°C.

$ sudo hddtemp /dev/sda
/dev/sda: SAMSUNG MZ7LN512HCHP-0001L              �: 39°C

Make it Silent

I installed thermald and soon after that it got more silent. Could be coincidence, though.

Intel vs Nvidia

Changing from Nvidia to Intel dropped the CPU temperature from roughly 50°C to roughly 40°C and the SSD to 38°C.

$ sensors

Adapter: ISA adapter
Package id 0:  +42.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +41.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +41.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
