The following system was used to test the cooler:
– Processor: Intel i5 6600K @ 3.9 GHz and overclocked to 4.5 GHz
– Motherboard: ASRock Fatal1ty Z270 Professional Gaming i7
– RAM: Ballistix Tactical Tracer 16GB DDR4 @ 2666MHz
– GPU: GeForce GTX 1070 Founder’s Edition
– SSD: Samsung 840 EVO 120GB
– HDD: WD 1 TB Blue
– PSU: Seasonic Snow Silent 750W Platinum
– Case: Phanteks Enthoo Luxe White
– Thermal compound: Arctic Cooling MX-4
Software used for testing the cooler:
– AIDA64 Extreme Version: 5.98.4800 (9/19/2018)
– Intel Burn Test v2.54
– Prime95 29.1
The cooler was tested with the CPU at the default turbo frequency of 3.9 GHz and overclocked to 4.5 GHz with a core voltage of 1.296 V.
Also, the included fans have been used at their maximum speed.
The room temperature was approximately 26°C (78°F), with 2°C margin of error.
The idle test consists of the CPU sitting idle at the desktop for 30 minutes, the temperature was measured at the end of the test.
The settings of the software used are the following:
Intel Burn Test v2.54 – Stress level: Maximum
Prime95 29.1- small FFT
AIDA64 Extreme Version – Temperature monitoring.
Each test was conducted for 40 minutes.
The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 2 db.
The Kotetsu Mark II due to its reduced size, does not interfere with the surrounding area of the CPU socket. The space between the graphics card and the heatsink is approximately 41mm.
The Scythe Kotetsu Mark II is an affordable CPU Cooler that borrows the mounting system and some of its features from other high end CPU Coolers released by Scythe.
The heatsink has a height of just 154mm and features four nickel-plated copper heatpipes and 56 aluminum fins. The overall fit and finish is great, there are no sharp edges on the fins and the heatpipes and base plate of the cooler have an even surface.
The mounting system is simple and solid, the only plastic components are the motherboard spacers used to keep the metalic plates straight. The total time required to install the CPU cooler and to boot the system is 5 minutes.
Thanks to its reduced size, the cooler does not interfere with the RAM slots of the motherboard or the first PCIe expansion slot.
The fan that is included with the Kotetsu Mark II is part of the Kaze Flex series and is a model that is being used with other more expensive CPU coolers, such as the Scythe Ninja 5. The fan is silent and has numerous features that will add more value to the overall package. Features such as rubber pads on the corners of the frame to dampen vibrations, or a fully sleeved cable for a better look.
The performance of the cooler is great, the CPU reached a temperature of 62 degrees Celsius running at the Turbo Boost frequency of 3.9 GHz. With the i5 6600K overclocked to 4.5GHz and the Kotetsu Mark II installed, the maximum temperature reached was 80 degrees Celsius.
In conclusion, the Scythe Kotetsu Mark II is an affordable entry level CPU cooler that offers a good cooling, being silent at the same time. The cooler also borrows some of the features from other Scythe CPU Coolers, such as the Ninja 5. The overall cooling performance is good when considering the size of the heatsink and the number of heatpipes. The CPU reaching a maximum temperature of 62 degrees Celsius running at 3.9 GHz.
