"Right then first things first I cleaned off the thermal pad that came with
this, this is the pink stuff make sure this goes! Also remove the pink tab
from the cooler. (you don't have to do this but I am a Perfectionist!!) and
clean the surface with medical alcohol (No this isn't my favorite tipple)
and apply a thin amount of white heat sink compound to the CPU and ORB.
Mounting of the ORB was very easy even though it does get very close to the
capacitors by the Socket A Housing. I was very impressed that on one side of
the mounting clip there were three eyelets compared to the normal one on
most Socket A heatsinks, this stopped the ORB from moving around whilst
securing the other side of the mounting clip and thus gave me plenty of
confidence that I hadn't spread the heatsink compound everywhere which is
the general feeling I get when fitting me generic heatsink with only one
eyelet either side and which also can rock about too much and chip the edge
of your CPU off which is highly dangerous!"
