Review : 3 Heat Sinks

OCIA has made a review of 3 heat sinks :
Thermalright's AX-7 , SIBAK's AC-02-625T and Thermaltake's Volcano 9 :

"To Cool or not Too Cool".... let's answer the question. Have you ever had that sinking feeling that you found out maybe your PC could be a little cooler than it is. As technology improves PCs are running faster and faster but as speed increases so does temperature and there is an inverse relationship with speed to the effectiveness of any cooler. Let's take a look at 3 Heat Sinks and see how effective they are in relation to each other. We'll look at the pros and cons of each of the three devices we're reviewing and I'll give you my opinion of which one fits the bill for my PC.
