I am new to building computers, thanks for responding.
So the GPU Parts under the Thermal Pads are called VRM, which stands for Voltage Regulator Module?
and again, To check GPU VRM Temperatures (temperature of parts under the thermal pads) in HWiNFO monitoring software, I should look at GPU VRM Temperature?
and for that I look at Memory Junction Temperature?
perhaps that complicates things.
actually I think i need to monitor temps after a fresh re-pad and re-paste, just to see things are running properly.
