CPU & GPU temps on catalina - Need help

Hey guys,

I'm running vanilla Catalina on 10.15.2. Using a gigabyte z270 motherboard, 7700k and GTX 780ti. Using HWMonitor or iStatMenus i only see SSD & HDD temperatures. Any way to see CPU and GPU temps?

I have FakeSMC.kext from the latest FakeSMC (RehabMan-FakeSMC-2018-0915), added all addons but nothing changed.

Any help? Thanks!
