Overheating and Fast Fan with Ubuntu 18.04 on Asus X550VX

My notebook (with NVIDIA) is running in abnormally fast fan speed and temp. At first I thought it was the graphic card, then I installed appropriate drivers for my graphic card, still having the same issue. I came across this question about the same issue. I followed the instruction to

• instal sensor-detect
• pwmconfig to test each fan
• /etc/fancontrol to create file
• add parameter acpi_enforce_resources=lax (I also put pci=nomsi and pci=noaer already)
• disable turbo boost

However, after booting a few times, my notebook still running at crazy temperature. I tried to run sensors and this is the result :

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:        +53.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +52.0°C  (high = +100.0°C, crit = +100.0°C)

I literally can hear the fans running super fast, sometimes randomly when I'm not even running anything (idle). I just recently switched to Ubuntu and and still trying to figure this out. Any advice on how I can overcome this issue ?
