Overclocking PenitumD 925

[manub]

Hi, is it possible to overclock my pentiumD 925? It's stock speed is 3Ghz, is it possible to OC it to 3.5 or 3.7? Also if it is possible then do i need an aftermarket cooler or is the stock fan enough?

My system Specs are

Intel Pentium D CPU 3014.6 MHz Presler (65 nm)

MB Model : Gigabyte 945GZM-S2 (rev 3.x)
