Core i7 against Scythe
Zipang
Let's start introducing the refrigerators! Zipang was the first to take place. It is a rib running parallel to the motherboard and having six heat conducting tubes. The pipes usually leave the base in two directions, which means that the heat reaches the heat emitter in 12 ways. In terms of the shape of the rib, it could also be an HTPC cooling if it were not much larger. Due to its size and the position of the slats, it is not even suitable for this purpose, as it can only be mounted on top of the fan, so it is guaranteed not to fit in an HTPC housing. Of course, Scythe wasn't meant to do that either, but rather to cool high-performance processors.
The 145 × 148 × 112 millimeter rib is 815 grams, which is not surprising in terms of dimensions. Ventilation is provided by a 14-centimeter fan that rotates thousands per minute while moving 51,82 cubic feet of air and producing 21 dBA of noise. Low noise and high airflow are clearly the advantages of a large fan.
As standard, we can cool s478, Intel LGA775 and Socket 754/939/940 and AM2 AMD processors. In this case, we also adapted it to a Core i7 processor with the help of the extra mount mentioned in the introduction.
Orochi
The largest rib in our test is the Orochi. It is a real monster, which is proven by nothing more than that the 120 × 194 × 155 millimeter size is associated with a weight of 1280 grams. In a word, it is brutal.
The design is similar to the Zipang if we look at the fan here as well as parallel to the motherboard. What makes it different, however, is the number of pipes. Orochi received 10 pieces of these copper tubes, which leave the sole in one direction. The size of the fan in this case is 14 centimeters, but the speed is only 500 rpm, and the noise is only half - that is, due to the 10,8 dBA, we are lucky for a particularly quiet piece.
There is no difference between Orochi and Zipang in terms of supported processors, it can only be installed on new Intel processors using the extra converter.
Kabuto
Kabuto is a new development from Scythe. It is similar in form to the Orochira, but much smaller. An important difference is that the lamella lamination does not consist of one piece, but of three separate units. This form has already appeared in other manufacturers, supposedly more effective than using a large heat emitter. The heat is transferred to the separate lamella units by two pipes, from which it can be quickly calculated that the new chiller works with six pipes.
Due to the dimensions, the rib was given “only” a 12-centimeter fan. The PWM-controlled air actuator operates in the range of 200 to 1300 rpm. Meanwhile, air delivery can vary between zero and 74,25 cubic feet as a function of speed. Zero, of course, means the steady state, which occurs when the fan speed falls below 200 rpm. According to the factory data, the minimum operating speed is 200, so below this the fan is suspected to stop working. Another important data is the noise level, which is between zero and 26,5 dBA. So at maximum speed, the unit is relatively loud. In our experience, below 20 dBA, the operation of a fan is not yet very audible when used under a table in a closed housing.
The Kabuto, as it belongs to the new generation, can also be fitted to the 1366 sockets by default, and in addition, the supported sockets are the same as the previous two delinquents.
