Some months ago we tested an excellent cooler from Zalman, CNPS10X Extreme. Today we are going to review another cooler from the same family, CNPS10X Flex. Will it perform like its brother? Let's see.

The name "Flex" stands for "Flexibility", meaning that the cooler doesn't come with a fan, allowing the user to choose the fan that best fits his or her needs.

The box is simple, with dark and blue shades.

Inside the box we found the cooler, installation hardware, manual and a syringe of thermal compound.

In Figure 3 we can see the cooler. An amazing detail is that it supports one or two fans. Also, if your CPU hasn't a high TDP and you have a well-ventilated case, you can use this cooler without adding any fan on it.
