"When you take a look at the cooler from an overhead view, you will be able to see that Silenx has decided to polish the top to add a little bit of cosmetic value to the cooler and add its company name, that way you will know exactly who is cooling your computer. You can see that all four of the heatpipes that pass through the entire cooler are evenly spaced as they pass through the the large number of fins mounted on them, which will ensure uniform cooling all over the cooler. The base of the cooler is very interesting as the copper heatpipes are visible and have direct contact with the IHS of the processor, allowing for a better transfer from the processor to the heatpipes."
