Swashbuckle :
I just built a rig with an amd3+ mobo and an FX 8120...i put the stock fan on it but its kinda loud and it overheats at times..is that normal for the 8120 if so should i invest in a hydro cooler? Lets sy like the H80 Corsair hydro series?
Most stock fans are loud, that's normal.
When you say it overheats, do you mean that it actually shuts down from overheating, or that it gets hotter than you want?
The liquid cooling kits are good, but generally overkill for most builds, a good air cooler would be significantly cheaper (something of the Cooler Master Hyper 212 flavor.)
But, if that's what you want, they work, and well.
One other question I'm compelled to ask: are you sure that your case has adequate ventilation?
