nf3 250gb chipset cooling

Anyone have a hsf reccomendation for the chipset on the nf3 250gb. I definetly need to find and alt. rather than the factory heatsink. Temps are getting to get so high on it that the heatsink will burn my finger as soon as I touch it.

I was thinking a copper vantec?

I did mine last night
its w/c and a tight fit but it works

I have Thermalright NB-1 lapped with 40mm fan.@ 1.8v and cooler is just barely worm(30-35 dergees).
