Have the same overheating problem on all my Lenovo laptops.
T520i (Intel graphics), Kernel: 4.6.0-040600 W510 (Intel/Nvidia), Kernel: 5.0.0-25 T530 (Intel/Nvidia), Kernel: 4.4.0-157
intel_pstate is not solving the problem. But I noticed it only overheats when watching videos in fullscreen mode.
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver gives -> acpi-cpufreq
