Megahalems Rev. B comes with only one holding system, supporting Intel sockets 775, 1156 and 1366 CPUs. Actually, the main difference between the first version to the revision B is the support to 1156 socket, as the earlier version fits only sockets 775 and 1366.
In Figure 7, you can see the installation hardware, and all those parts must be used, which makes the installation a little complicated. Note the four metal wire clips on the bottom of the picture, which holds one or two fans, besides the cooler comes with no fan at all.
Before installing the cooler itself, you must install a frame in the motherboard, made by the backplate, screws, nuts and two aluminum tabs that stay on the component side of the motherboard. In order to install this, you must remove the motherboard from the case, unless it grants access to the solder side of the motherboard. In Figure 8, you can see this frame installed.
In Figure 9 we can see the cooler attached to the frame. It was a hard task to put it on place, since a third aluminum bar over the cooler base holds the cooler, and this bar is attached to the motherboard bars with two screws. The problem was those two screws didn’t easely pass through the holder holes, and the only way we menage to do this was usign brute force (a lot of brute force, actually).
In Figure 10, we can see Megahalems B with the Silverstone FM123 fan on place. Keep in mind our results are based on this fan and, with another fan, you can get a different performance.
In Figure 11 we can see the cooler installed into the case. It is not the biggest cooler we have seen, but it is very tall. It did not interfered with any motherboard component, but the fan position can impossibilitate the use of a tall heatsink memory module on the first slot.
