Any type of cooler that has more than 4 heatpipes and dual fans installed on the sides. Aluminum structure and aluminum base. Copper composites the heat faster but not dissinpation. It is thicker in density than aluminum, platinum & titanium while all of these metals are light in nature thus I can't see how copper is better. I don't remember characteristics of each metal from chemistry class but I'm certain about the dissinpation.
We're all equally different with opinions, some suit for flashy looks, some pick for a decent price & some buy for the quality of the product.
There is a large variety of cpu heatsinks on the market. Just need to research & decide which suits your motherboard the most to it's potential.
