How to check CPU / GPU Temps

[Kiaeneto]

I'm building my first PC later today and after I get it built how do I check the CPU / GPU while at idle and under full load? I see these people on youtube run stress test for the CPU / GPU for temps but is there another way?

I got this MOBO, this CPU, this AIO WATER COOLER and this GPU. If that matters at all as to finding the temps.
