Many boards include built-in sensors, which helps a lot. However, if you need your own probe, you're essentially handling everything by yourself—just you and a bit of duct tape, maybe?
The default sensors include a few built-in options. You won't find spare probes to attach freely, but you can purchase thermal probes separately. Cost varies based on the display system you require.
GPU temperatures can reach up to your GPU's limit, and most contemporary GPUs will indicate their heat levels. For creating a sensor display, J2C published a video on the topic some time ago.
Using hwinfo64 provides extensive data and statistics, allowing you to reorder them as desired. You can also display information on-screen if you install the Riva Tuner Statistics server. It appears to function best with 3D applications, which is a notable limitation by the developers. What software did he employ? A fixed sensor display would be ideal (or an overlay if feasible), but that seems unavailable with Riva Tuner.
