just dont know which one to buy for the E8400
if you are buying an older type one, the best are the Q6600/q6700 ones.
i suppose if you can get one from a qx9650 the fan on thoe is huge, but generally they are expensive on ebay.
The newest ones are a little shorter than the older ones which were the same size as p4 ones.
from what i've seen ,
celeron D 3xx series has had the older height, PWMM fan, and no copper
celeron D 420 i had , had the new short height, a 3 pin fan, and no copper
core 2 duo e6300 i had , had the older tall height, pwmm fan, small copper core
pentium D 8xx series i've seen was more or less the same as the e6300 one and p4 ones i've seen
q6600 ones i've seen in pictures have a larger copper core than the pentium D or core 2 ones.
i had an e4300 and e4400 also and those have the larger height but no copper with 4 pin pwmm fan.
the e7200 i have now, has a shorter heatsink like the celeron 420 but with a pwmm fan.
i think in general you can put the bigger ones on the cpus that came with the smaller ones. Intel definitely does this for cost reasons. And possibly even weight reasons.
metals in general cost A LOT of money and if intel can save $1 by not including a copper core when its not needed (since well they are only giving you fans that are for stock clocks) that is a lot of money. Since metals generally are expensive now, especially copper.
