65C doesn't exceed the max temp, but it is way too hot IMO. Generally, it
should run under 60C under load. And like a light bulb, failure usually
occurs during rapid cooling or heating, meaning when powering up or
powering down. You could try lowering the default settings for the cpu and
you may get it to work at a slower speed. But not worth the effort IMO
when you can get a newer, much faster, system these days for peanuts.
