Good news or bad news?

Hi.

i just tried to overclock my AMD PHENOM II X4 945 3.00 GHZ TO 3.4 GHZ @ STOCK VOLTS AND STOCK FAN AND it was great and successful

how far this stock fan can handle? , and i m going to buy cooler master hyper 212 though but i am just asking

how far can the stock fan go? and how far the cooler master hyper 212 can go?

btw my cpu temp was @ normal case while overclocked 33-37

under prime 95 stress it was 59-63

good news or just misreading?
