How to get the temperature of MacBook hardware without extra software? We can use iStat Menus and other software. 

Is it possible to get the temperature of MacBook hardware components without extra software? To use only programs already installed/delivered with MBP?
There seems to be no discernable way to find the temperature of hardware components purely without 3rd party software.
