This looks very similar in many respects to the link you posted. I'd check the fans or do an outright replacement of all the fans! I know I did a look through Octane case fans recently and I KNOW the heart ASIC Fan was still made and I thought the others were too.

Perhaps as a preventative, since Octane should have had thermal monitoring...but doesn't, that a "fan kit" needs to be made for Octane users to just whole-hog replace their fans after all this time. Since they run so hot and fans are critical.

But it looks like I'd agree, likely damage has been done, I do hope it's the graphics, as implied, so you can get back to work.
