Do you need an aftermarket HS's on p5WDH Deluxe

[wstcoaster07]

I am currently OCing my E6600 on my P5W DH Deluxe @ 3.0 GhZ (333*9). My question is if the stock chipset cooler is good enough to OC to 3.4 or if I need to install an aftermarket cooling system. I would like to hit 3.4 w/ 425FSB and 8 multiplier. but worried about the increase in voltage required producing too much heat for the chipsets.

*should I go for 378 FSB @ 9x mult or 425 @ 8x??

from what i have heard, reaching 3.4 should not be an issue. key word being "SHOULD" haha.
