thanks everyone!

i think the swiftech is better because of the copper base, this also makes it heavier....if thats an issue?

A review for the thermalright NB1 i read seen a reduction in NB temps at stock settings but when it was overclocked the temp was the same as with the stock heat sink.....i think something is up with that.

I'm still searching for more reviews on it

They actually perform about the same. The Thermalright is cheaper but noisier. The Swiftech is more expensive, but quieter and slightly (very sightly) edges out the Thermalright. I'd say that if you want to save a little money to go with the Thermalright but if you can afford it go with the Swiftech.
