Hi im looking to get a new mobo and a new heat sink to go with it seen as the mobo ive got atm was suppose to be temporary. The heat sink im looking to get is a Zalman CNPS9700NT (Heatsink), ive heard that its quite big. The problem that ive come across is the new mobo i was thinking of getting Asus crosshair nForce 590 SLI (MOBO). I think there might be a problem with the heatsink, it might be to big for the mobo. I was thinking it might hit the copper pipes. Has any body got any thoughts on this?
