When it comes to installing a heatsink, the ease is usually determined by the type of processor being used. Since I am testing on an AMD based S939 system, I have come to expect everything from very simple to massively complex installations. The 3D Rocket II falls into the very simple category. Motherboard removal is certainly not required, but you will need to make sure that the plastic bracket that surrounds the processor block is firmly secured in place. You will not be needing this for the installation; you just need it to be there.
Remember, this particular model comes equipped with brackets that work for nearly all current processor types. Since the test system is AMD based, the installation notes may differ from your own system.
That said, the K8 mount is a matter of simplicity. It slides through the open riser portion of the cooler, then fits over the lugs of the bracket. It is slightly reminiscent of the old Socket A days, but the mount in this case has a latch that locks the heatsink firmly in place. After installation I noted no movement in the cooler, even when standing the case up and allowing gravity to come into play. It is very stable and should have no problems residing in your system in any position.
NOTE: Due to the weight involved with this cooling solution, I highly recommend you remove this cooler before moving the system for LAN play or moving. While the unit is very stable, the weight may be too much for the restraint system to handle if the system is moved or bounced around.
The shot above shows you what the cooler looks like from a straight down angle. While it is large, it doesn't appear to be too awkward mounted atop a DFI motherboard. Let's get a little different view, though.
This angle lets you see how the heatsink fits into a standard mid-sized tower case. The riser design makes sure that the MOSFETs and memory modules are cleared, so you should have no problems with fit unless you are using a SFF-type system. In that case you will want to make sure of your measurements before using this cooler...but then, that is not what it was designed for anyway.
