Newly Built Computer, CPU temperature really low

AMD temp's are measured in an odd way which is explained in detail here AMD Temp Information and Guide

"Core Temp" is what AMD refers to as "TCTL" and is a non-physical temperature on an arbitrary scale measured in degrees. It does not represent an actual physical temperature like die or case temperature

Basically the temp is not accurate until it reaches 40-45c and will show the wrong temp when idle.

Most program's will read the core temp which is the temp you are seeing but not the true temp while below 40-45c. If you use a program like HWinfo64 HWiNFO, HWiNFO32/64 - Download it will show you the core temp as well as the socket temp like in my screen shot. It's the load temp's you need to watch but if you want to know the idle temp just look at the socket temp and use the core temp reading for true load temp's.



Never run more than 1 program which monitors temp's though as running multiple app's will cause false readings.
