The Susanoo cooler is a beast in every facet. It shrouds entire motherboards, packs four fans side-by-side, and has a staggering weave of 12 heatpipes emanating from the base. The fans were surprisingly quiet, even when run at full speed. The included PWM fan controller is a great feature, and can keep your fans extra-quiet when you don't need to be pushing them. It undoubtedly helped cool the RAM, and Northbridge on the motherboard, and since it came right up snug to my video card, it definitely didn't hurt that either.
The CM Storm Enforcer case it was put in is an extra-wide case, and I didn't have any clearance issues. Be very wary of the necessary dimensions if you'd like to take the leap with on of these. Despite its size, it didn't seem as though it were putting any more stress than other large coolers I have tested, and noticed negligible flex in the motherboard itself. Installation was straight forward, although it must be done with the motherboard already installed in the case, which means your motherboard tray is going to need to have a CPU retention hole in it. Another set of hands doesn't hurt, but I was able to do it by myself without too much trouble.
The Susanoo performed very well in load testing as well, although in the overclocked tests it was outperformed by the Noctua NH-C14, a comparably-priced top flow cooler (~$95), at a 25 percent overclock. One thing to consider, however, is that mammoth coolers generally show their true colors when they are loaded heavily or more in the range they were engineered for, and it could be that pushing the Susanoo further would show that it's much more efficient under extreme loadings, which is something this cooler was clearly meant to do. We have found others have produced results which show the Susanoo does far better when "pushed." When you allow those extra six heatpipes to start picking up the slack is when it would likely begin to pull forward, and we'll be looking out for extreme overclock tests on the Susanoo in the near future. I also expect that full tower cases would take better advantage of the Susanoo, as I had to remove all of the case fans from the back and top to allow it to fit, which may have othwerwise aided its performance against other smaller coolers. However, for a more casual user, the Susanoo seems like a daunting choice as a monstrous and heavy piece of equipment, and there are a number of potential clearance issues.
- Four-fan PWM Controller
- Quiet Slipstream fans
- "Extra" cooling of RAM, NB, etc
- Secure mounting bracket
- Good performance
- Size constrains many cases
- Need CPU retention hole as motherboard needs to be installed prior to mounting
- Had to remove rear exhaust fans, and no room to mount top exhaust fans
