Comment 64 for bug 1768976

Same problem here:

Lenovo ThinkPad T410s
Intel i5 (1st gen, 2.53Ghz)
NVidia NVS3100M graphics

Kernel 4.4 in 16.04 idles at 35°C - 37°C (fresh, high-quality thermal paste applied a week ago).

Kernel 4.15 in 18.04 idles at 48°C - 52°C.

Only Dropbox and Megasync in the background; htop shows very low CPU use from these 2 apps.

Overall system CPU usage (idle) doesn't go above 1.3% - 2% range.

Same workflow from 16.04 + kernel 4.4 runs 20°C hotter in 18.04 + kernel 4.15.

Regular operation with Chromium and Emacs drives temperature to 76°C - 80°C.

Critical temperature is 95°C before shutdown.

This is running really hot.
