Yes use CPU-Z To find out Family Model Stepping & Revision. That way I will know what CPU you have...
Also you have quite nice FAN in there... has double FAN...but only 3 pings connector. Meaning that there is not speed control on the FAN. Did the previous heat sink that you used have 4 Pings power connector?
