dust remove and look at ur laptop's temperature first
i dont need a cooler anymore since i got dust removal, even play games

I think the ZM NC2000/3000 isn't worth to buy because they are very very expensive
and i see the reviews they says NC3000 is better than NC2000
but NC3000's design is easy to diy. just get CM Notepal U3 and mod the fan ur self, can even make a cooler powerful than nc3000,
if u made a very very powerful cooler , for ex u uses 6x 120mm fans,
cost below RM150, and how much is NC3000?

Of course if u wan the "zalman" of u wan very very high quality aluminium then u can go for it
but if u wan go for zalman i recommend u wait for nc3000
