and if you stick your finger ont heother 14 boxes w/ p4-2.8 cpus
it'd be foolishly throwing $$ down the drain in a shuttle box
- cpu dies in 1/2 life-cycle for every 10C increase in
operating temp

cooling is a factor of...
- air flow
- density of air
- cleanliness of air
- grade of copper/aluminum
- smoothness of copper/aluminum heatsink
- thermal conductivity of heatsink compound
- thermal conductivity of copper, aluminum
- thermal blah-parameters of copper, aluminum, ...
- source of the heat
... lots of variables...
- identical cpu and indentical heatsink will give you
different ambient temp in different cases w/ different heat sink
compound
- problem with p4-2.4 and p4-2.8 was way way way too noticeable of
heatsink problems ( off the shelf.. un-modified )
- heat problem is so bad, i will NOT attempt to fix(customize)
the heat problem and instead just say/flag that they have a
problem and let them decide ... i'm not gonna replace 13pcs of
$275 cpu
- so now i know, not to use p4-2.8 in those boxes ...
whie some other versions, variations might work ... donno ...
- try it and see ...
