I recently upgraded my processor to an IntelCore 2 Quad Q9650 on a ASUS P5N-T Deluxe mother board. When I check in Task manager and in Speedfan 4.41 all I see are two cores with a temperature difference in Speedfan between the cores that ranges from 7-10 degrees Celsius ex (53 and 63). Temp does not exceed 65.
a. Why am I seeing only two cores on a quad core processor?
b. What would cause that large of a temperature difference?
