This can be done also for other CPUs (without build-in thermal
throttling too!) if the MoBo has really measuring temps from onDie
diode (or using external gadget like I do to do that!), so that MoBo
can throttle Cpu down! (tipical: newer AMD sistems).
You just have to set in the bios than CPU throttling in power
saving options for example to 12,5% (default is set to 66%-not
enough!). When this MoBo feature kicks-in, the PC becomes sluggish
like a turtle, but prevents CPU thermal runaway (if HS falls off or
fan dies). I successfuly tested this on my machine while experimenting
with running my OC-ed machine running it w/o fans at all (see my site
under comp/benchs & how to check if temps are read trully from inner
Cpu diode under Burn-in article)
This MoBo feature is commonly left set at defaults
/disengaged/ when shiped & not commonly known ... (waste majority of
board has a posibility to enable this for years inside Bios settings,
but practically no-one uses it). In my case CPU die temp so did not
pass 90°C - the feature starts kicking in a bit after passing 75°C &
"brakes" CPU more & more till 80°C when throttling il at max (12,5%)
preventing thermal runaway of CPU ... Win98 did not crash at all!
