Ile, Seems that you should drop green drive a bit lower so that neckboards runs same temperature (second picture) Mr. Green

Car, lucky guess: Ford Cortina?

True, but usually more of a 'throw it out, it's toasted' type of parts sale. I'll take it, but I'd rather do an actual repair. Board swapping isn't a challenge.

Boy, I dunno, fan mods seem all the more needed to me IF temp is detrimental to a given part. That is, I know electrolytic caps do have longer lifetimes with cooler temps...but I'm not sure on the super-hot MOSFETs. 80decC components could use some mini, additional direct cooling - some of those tiny 3cm-ish fans located near components couldn't hurt and are nearly silent and easy to mount with sheet metal.

How hot is hot? What temp does red represent in the thermal images of the 808??

Camera have automatic scaling, so scale vary from picture to picture. Celcius scale is printed at every picture, so for example Hsift board picture have around 125 Celcius degree (dark red) at hottest area.
