The Extreme Edition II can be bought with 3 different sets of CPU-Kits:

// //
Left to right: P4 S775 // P4 S478 & A64 S754/939/940 // AMD Athlon XP

I asked for the S478/S754 kit as I had both systems lying around for testing;


Left: motherboard installation pieces for both A64/P4
Right: Clamshell & A64 material

The clamshell needs to go over the evaporator head so start by pulling back the isolation a bit, then add a heating element on the inside of the clamshell, the element is adhesive and pretty easy to install, finally push the evap-head through the shell and you are ready for the next step



Add the white insulation blocks and push them all together, make sure to make the wire of the heat element lead away through the top of the clamshell, otherwise you need to dissemble to whole thing again, which can be quite a challenge, but not impossible.



Comparing the evaporator head of the XE II to the XE you can notice quite a difference in size, here the one from the XE (picture from [H]'s review here)



The larger contact area is certainly also responsible for the higher performance rating of the XE II.

Now we're ready to install the mounting gear onto the motherboard, with the help of the removable mobo-panel it becomes quite easy ->
