That does seem hot for a 700mhz CPU...do you know bout heating up your CPU to
at least 60-65'C for a moment, then backing off to complete phase-change on thermal pad? This would lower your temps slightly as the pad would "melt-in"
a bit. Just pull off case while running PC, I assume you have CPU temp monitor to watch, disconnect CPU fan till temps rise -> then reconnect... 😀
