CNPS10X Flex is compatible, according to the manufacturer’s webpage, with socket LGA775, 1156, AM3, AM2+, AM2, 939 and 754 CPUs, but our sample didn’t come with the clip for use it with sockets 939 and 754. But, frankly speaking, no one will buy a cooler like this to install on such obsolete CPU.
The clips that come with the cooler are simple and follow the same design. There is a pair of clips for Intel CPUs and another for AMD processors. In Figure 10 we can see the cooler with the Intel clips attached the base.
In Figure 11 we see the metallic backplate, which makes installation more stable and avoids the motherboard from bending due to the applied pressure. There is only one backplate used for all sockets, and all you have to do is to put the nuts in the correct place. An excellent system with plastic holders keeps the nuts in place during installation. So, the installation is very simple, even though you have to remove the motherboard from the case (unless it offers access to the solder side of the motherboard).
In Figure 12 we can see CNPS10X Flex installed on our motherboard, still without the fan. Note the thin black strips on the heatsink: they are strips of self-adhesive rubber that helps absorbing noise and vibration from the fan.
In Figure 13, you can see the cooler installed inside our case, with the fan in place.
