The 120 mm fan used on Kabuto is attached to the product using two metal clips, with easy removal and installation. There is no vibration absorbing system between the fan and the heatsink. The power plug is a 4-pin miniature type, thus with PWM speed control.
Kabuto installation is quite simple. First, you must screw the required clip (according to your CPU socket) to the cooler base. It comes with three clips. One (shown in Figure 11) supports sockets 775 and 1366 Intel processors, with fastening pegs like the Intel stock cooler system. The second one fits sockets AM3, AM2+, AM2, 939 and 754 AMD processors. A third clip allows the installation of old (and obsolete) socket 478 CPUs.
Installing this cooler on a socket LGA775 motherboard we found some difficulty in "clicking" the peg located near the power supply, because the cooler stays over the clips and in a mid-tower case there is no room to put our hand between the cooler and the power supply. In figure 12 you can see how it looks like after installed in our case: it is lower than tower coolers using 120 mm fans and thus will fit most "common" cases.
