Replace e4300 stock cooler?

Arctic Cooler 7, about 23 US$

Coolermaster makes some heatsinks that were designed for prescotts. I have one for my e4300 it moves 80cu feet of air with a 95mm fan and is pretty quiet at full speed, and while made of aluminium it has a copper insert that makes contact with the CPU. It runs $10-16 shipped in the US, and is available through European sites as well.

Will it REALLY do the job better than the stock cooler?

How about TITAN Siberia?

I know it's more expensive, retails at $27-$30, more than I expect, but is it really Uber?

Cools not only CPU, but also NB with it's huge 12 cm fan..

RPM: 1400 - 2900
Noise Level : < 27 - 45 dBA
