I guess I might a well just ask everything I want to know here...
*NOTE: Refer to the parts listed below in order to answer some of the questions.*

1. Is a 3 pin CPU fan & heatsink compatible with the 4 pins on my mobo? (I AM NOT TALKING ABOUT MOLEX I AM TALKING ABOUT WHERE IT SAYS "CPU FAN")

2. If I plan on unlocking the 2 cores that are dormant on the Phenom II X2 555 Black Edition
What Kind of heatsink should I get? (MAYBE over clocking, but 100% attempt to unlock both cores.)

3. What Heatsinks are compatible with my CPU/Mobo (Do the AM2, AM2+ work aswell as the AM3 Brackets?)

4. What does the Phenom II X2 555 compare to in terms of going up against an intel chip?
i.e. an i3, i5, i7 processor..? (Just so I get some perspective.

5. How exactly do I unlock my two extra cores when I get my stuff? (Unleash Mode with my asus mobo in BIOS?)

6. What happens if one or both of the two extra cores on my CPU is unstable? Will I be able to boot without clearing the CMOS for example?

7. Is there any other AMD CPU out there for the same price five or take 20-30 bucks that is better than the dual core Phenom?

8. Which heatsink do I choose out of these 3 considering all of the questions above?

1.) Yes, most motherboards are made so they can do Pulse Width Modulation (4 pin) or Voltage control (3 pin)

3.) Yep, the AMD bracket hasn't really changed over the years.

Thanks for the 2 most important answers, but for best answer I really need all of them answered.

I need someone who knows everything about unlocking cores on AMD CPUs and etc.

Thanks again EXT64!

1.) Yes.

2.) If you are planning to unlock the cores only at first, then the stock cooler is fine AFAIK - correct me if I'm wrong, but it's pretty much the same as the Phenom II X4 heatsinks.

3.) AM2, AM2+ and AM3 use the same bracket.

4.) The Phenom II X2 555 performs around the same as a Core 2 Duo E8300 or Pentium G6950.

5.) Set ACC (Automatic Clock Calibration) to auto, or something similar.

6.) If your CPU is unstable, it either won't boot and revert to normal settings, or you can access Windows, Prime 95 and if it fails one or two cores are unstable, you would be better off asking someone who has unlocked it, hopefully someone does.

7.) In terms of what? You can get an Athlon II X4, which would be better for multitasking, but worse for gaming. Then you got the OEM Phenom II X3 720 for $104.99, then you'd have to buy an aftermarket HSF.

8.) Cooler Master Hyper 212 Plus.
