i hope this is the right place to request an article.
on the Hardware forums, all the time people are saying "this heatsink is better than that heatsink".
people say the scythe ninja is better than ... whatever OTHER heat sink.
it would be great if Tom's could do an article that measures the thermal resistance of a lot of the heat-sinks used by over-clockers, vs. the factory heatsinks (from AMD & intel).
for example, Zalman states a thermal resistance of .12 degrees C per watt for the 9500.
so 100 watts on the base, with 20 degree C input air, we should see a 32 degree C base (.12 x 100 watts). then there will be an additional "delta" across the interface where we put the AS Ceramique.
i got a mechanical engineering degree from a junior college near palo alto in 1979 and have worked in silicon valley since then. most of my time has been spent in R & D, for example a team of 15 people, it's my job to stand in front of the government or another contractor and say, "the junction temperature on this device will be X degrees max., based on this combination of measured and calculated values."
of course there's more to using the Zalman 9500 than installing it properly on the CPU. you have to feed it cool air and you have to remove the hot air.
then there's other little details like, the Zalman 7700 blows air on the north bridge and the RAM, with most board layouts, whereas the 9500 doesn't. so with the 9500 - and a lot of other heat sink fans - if you want to cool the devices that support the CPU, you need to strategically position case fans.
so i suppose a thorough report on heat sink fans would include not just an independent measurement of device (heat sink fan) performance - compared to the manufacturers' spec ... a lot of them don't even state a thermal resistance - it would state the "boundary conditions"/ configuration to achieve the spec - or to improve on it.
anyway, it would be nice to see an article to settle some of the Zalman-Thermal take debates in the Hardware Forums.
i just did a search on the main website using the key words "heat sink fan". i didn't find an article more recent than 2002.
