Slow, Fans running max non-stop
Laptop is insanely sluggish—essentially unusable. When I am able to finally check the activity monitor, the CPU usage exceeds 100%. Did a fresh install of the OS hoping it would fix things, but nothing. Fans run non-stop at maximum speed. Not quite sure how to fix or diagnose the issue.

Let's run the onboard diagnostics, restart your system and press the D key yo enter. Let us know what the errors are.
Reference: Mac startup key combinations

Holding the D key while restarting the system results in a black screen. MBP runs (as evident by the fans revving to max) but it’s just a black screen if I hold down the D key. Doing Option + D results in an error: “Cannot load ‘EFI/Drivers/TestSupport.efi’

Well, that sucks, Thanks Apple! When Apple updated the firmware in High Sierra they messed up the onboard diags and still haven't fix it!
On to plan-B At this point you'll need to install TG Pro so you can get a better idea on what your sensors are doing. Post a snapshot of the main window making sure you expand it so all of the sensors are visible (the right slider needs to disappear) 기존 질문에 이미지 추가하기
Let's see if they can tell us what we need to tackle.
