Here’s a video of the problem: https://www.youtube.com/watch?v=fMcJegoX… And here’s a video of the problem with full load and high temps on the processor: https://www.youtube.com/watch?v=6b5Vi-ru… The fans seem to just not start at all. Is this a fan issue or something bigger?

It could be a fan issue, an issue with the fan controller on the board, an issue with the temperature sensors, or even a strange issue with software. On the software side, I have only ever seen that with video cards that let you control the fan speed from the driver. EDIT: Removing OpenHardwareMonitor suggestion. Saw in second video you have a monitor going.
