Update:
Got the wires soldered in place of the pins, worked like a charm! My joints aren't the cleanest and I'm not too proud of them, honestly but I can't complain too much.
Pics in the sun are much better than pics in a dimly lit house haha
I noticed some oxidation or corrosion or something that I think finally freed itself in the loop on the boot, so I suppose I'll need to drain and flush the loop at some point when I can.
Temps were much better this time on the GPU, ran part of the time spy so tress test and it was at 84c, sustained testing later with doom eternal
