So i decided to upgrade my casual gaming pc. Just today i bought a E8400 3ghz 6mb 1333fsb core 2 duo as an upgrade to replace my old E6420 2.13ghz 4mb 1066fsb. Here's all the specs for these cpu's including voltages etc. (just click the "specifications" tab) :
http://www.cpu-world.com/Compare/593/Intel_Core_2_Duo_E6420_vs_Intel_Core_2_Duo_E8400.html

The cooler i'm using is D60188-001
As it says in a webstore description i found, it supports CPU's up to E6700 core 2 duo (2,66ghz)
Here's the manual for the cooler, it has reference tests that start at page 42, but quite frankly, i don't understand them well enough :/ :

So, the newer cpu has a smaller die(45 instead of 65), has a smaller max power watt dissipation and a slightly smaller maximum core voltage. So it made me think i could possibly use the old cooler instead of buying a new one? Cause from what i understand, when it comes to heat it kind of depends on the voltage? The only things that worry me are the different die size (even though it's smaller) and the higher clock/mem/fsb (though i don't know if it has an impact on the amount of heat produced).

The cooler fits the socket but the heatsink is half the size of the reference cooler that comes with E8400 so it is doesn't cool enough.
My advice is get an aftermarket cooler, if money is problem I am sure you can find some decent ones really cheap altough not good enough for overclocking they are definitely more quiet than intel's stock cooler.

If you install that cooler make sure you clean it well and apply thermal compound, run prime95 along with a app that can read core temps like speedfan, but I really think that cooler will not be enough.

Take into consideration that maximum operating temperature for intel E8400 is 72.4 C
