I plan on returning the item ASAP and ordering a smaller cooler today. With 2-day shipping, I should get my new cooler by Tuesday/Wednesday (business days). I was wondering if I could temporarily use my old stock from an AMD Athlon X2 240 in my new AMD Athlon II X4 Propus 3.1GHz processor. I don't have any case fans on my mid-size ATX.
P.S. The new CPU that I ordered is an OEM so it doesn't come with stock heatsink/fan
