Cooling Q's

I have recently purchased a P4-M 2000mhz which does 2640 at 1.43v but thats where the previous owners board tops out at. I am probably going to be strapping a 1.6 vcore to it to hit a nice 300fsb stock is 1.3v. Now my question is will the following be adequate?

1x rear 80mm exhaust fan(should i have 2?)
1x side blowing on hsf 92mm fan
2x front intake 80mm fans
1x blowhole 120mm fan
1x Zalman cnps7000cu

will i need any other cooling? eg: what kind of northbridge cooler should i get?

the mobo is most likely going to be a IC-7. and the TIM will be PCM+.

thanks for all your answers.

I would go watercooled and get the maximum out of that madness as you can.

if not watercooling, then it looks like that would considering the low vcore your running
