Specs are as follows:
CPU: Phenom II X4 955 BE~Stock Settings. Voltage @ 1.024V in CPU-z right now.
RAM:2x4GB G.Skill Ripjaws DDR3 1600~ CPU-z is showing correct timings and voltages
GPU: Sapphire Radeon HD 6950~ Flashed to 6970, max temp was 85C during testing
MOBO: Gigabyte AM3 AMD 890GX
CASE: Antec Nine Hundred Two
Scores in 3d mark
Is there something wrong with my scores? Is this a cause of my CPU bottlenecking? what could be wrong?
It's safe to try, just monitor temps. Once you start increasing voltage though the temps will begin to increase more significantly so it will certainly limit the OC potential. But you have a Black Edition, might as well spend $30 on a Hyper 212 Plus and get a good OC out of it.
You don't really need a 2nd fan though, but that one should be ok... however, I wouldn't get that one. I'd first make sure that the mobo supports 2 PWM fans, and then just make sure the 2nd fan is PWM, that way the mobo can change fan speeds based on temp.
