Duron 1.6 's Cooler Master heatsink has cheap zinc oxide paste

This cpu ( distributed by Adventure Multi Devices SB, PJ, Msia ) came
with this h-sink & paste. Because this h-sink 's contact area with cpu's
die is coarse, hence quality of thermal paste becomes very important,
yet h-sink has just cheap zinc oxide paste.
Cpu cooling was noticeably bad ; [i] temperature does not drop fast,
after ACPI is activated [ii] a fan* fitted behind socket A could reduce
remnant heat by 44.4%, indicating 15ºC difference between cpu's &
ambient air temperature [iii] hdd speed 4.8 mb/s in WinTune98 was
lower than usual .
I had to remove all the plugs & cards, then mboard from casing, then
h-sink & fan plug, clean off cheap paste ( on h-sink & cpu die ) using
alcohol & cotton bud, apply Arctic Silver I paste to die, re-fit hsink,
plugs & cards. Real chore.
Result [i] cpu temperature drops faster, with ACPI activated [ii] * can
reduce remnant heat by just 30% [iii] cpu responds fstr to commands
[iv] hdd speed in WinTune returned to 5.7 mb/s [v] video speed in Win
Tune rose from 179 to 182 mp/s.
Users / buyers beware.

Wow...all that just by changing thermal pate...It's a miracle !!!!
BTW.....WTF is 'remnant heat'?

*****Replace 'NOSPAM' with 'btinternet' in the reply address*****

FWIW, there is no chance that by only changing the thermal paste [and,
presumably, reducing the CPU temp], that the cpu would speed up or the hdd
would speed up or video performance would increase. While excessive temps
could cause anyone of them to fail, simply changing their temps will no
change their performance.

You have to look elsewhere for the causes for change in performance. [PS.
The differences you should could be simply from variations from one test to
another - i.e., each time you run the tests, you can get slighly different
results - unless you are very careful to insure the pc is in exactly the
same state each time]
