Im going to get the AMD Athlon 64 X2 Dual Core 4200+ 2.20GHz (Socket AM2) - Retail. OC Stock Code: CP-168-AM, and I noted the description says "A new pin out configuration which requires new heat sink fan configuration is also required". Does this Retail version come with the H/S fan? In not, what do you recomend? (upto £30 inc vat and delivery if poss).
