     Sorry, I don't know of any review sites.  I'm using the Speeze
"Falconrock" 5F286B cooler.  It's inexpensive (in the US, at least),
cools well, and has a large fan for relatively quiet operation (but is
tricky to seat properly, and is east to install incorrectly):


Sorry about the above link to a commercial site (this where I bought
mine), but I cannot find the manufacturer link for this cooler.

     Neither did I.  ;-)

     However, using an XP-M on a standard motherboard is not recommended
by AMD.  One of the reasons why is that the XP-M uses a different method
for signalling the CPU's core voltage to the motherboard, and so many
(all?)  motherboards cannot recognize and properly set the voltage.  On
my ABIT NF7-S motherboard, my XP-M isn't recognized, and initially set
the core voltage to 1.7V (together with a 100MHz bus speed and a 5X or
6X multiplier).  Unfortunately, there appears to be no technical
documentation available on AMD's website for the XP-M, and so I wasn't
sure what core voltage to use.  The place from which I bought the CPU
said "1.35V"; confusing all this is a press release (or somesuch) on
AMD's site which says that the XP-M's voltage can vary from 1.2-1.4V
during operation, as a power-saving method.  I'm now using 1.35V, and
everything appears to be working.
