Technical characteristics Scythe Kotetsu Mark II

The difference between generations

We all have Scythe as a benchmark in performance and noise control. Their heatsinks have often boasted of large volumes to increase their cooling capacity, but they also have ranges like this that enjoy a more manageable design and also more economical compared to other ranges of the brand such as the Ninja or the massive Mugen.

Kotetsu Mark II, as its name suggests, is the second generation in a series that Scythe has started to introduce powerful, but cheaper models, with controlled sizes and asymmetric designs that allow it to be installed on any type of computer and accompanied by any type of component..

This new version reduces its size in height, five millimeters, but brings with it significant design improvements and is more efficient thanks to the improvement in its production methods.

One of the most notable differences is that now the four copper heatpipes and their contact base, also in copper, are nickel-plated, which significantly increases their durability, in addition to offering a more careful and homogeneous finish with the entire design. This is also complemented by a top cap that ends the heatsink with a more modern and aesthetic finish.

Scythe has also introduced a completely asymmetric design, which we will talk about later, and has also significantly improved its anchoring system, which inherits from the most recent and powerful models of the brand, as well as introducing a new Kaze Flex 120 PWM fan., one of the most efficient of the brand.

The dissipation block

It has the classic tower design, but Scythe takes care that the size of this series is adequate so that it is a very friendly heatsink with all types of computers. Its height is 154 mm and it is completely made of aluminum, with four copper heatpipes that cover its entire height divided into two main blocks.

The blades have been designed in such a way that they maximize the heat exchange surface, but also improve air flow, especially at low turns, being a very efficient heatsink with fans at low revolutions.

Scythe has made a double asymmetry in this dissipation block with respect to the anchor of the base. This double asymmetry focuses on positioning the heatsink further up and back in position with respect to the processor socket. It is 10 mm more to the right side than the left and is almost 20 mm behind.

With these differences, the Scythe Kotetsu Mark II leaves more space for high-altitude memories, which will be perfectly saved in front of the processor and also offers more space for graphics cards with backplates.

The new fan

Tower, vertical heatsink designs like this haven't changed much in years except for clever details like the ones we've found on the Kotetsu Mark II. The part where there is much room for improvement is in the use of more efficient fans, less noisy and better adapted to the consumption of the processors of each generation.

The Kotetsu Mark II enjoys a large submerged bearing fan with high precision sealing. This type of bearing has a remarkable longevity thanks to the decrease in friction. This in particular has an average useful life of around 120, 000 hours. This type of bearing also has other advantages, such as lower noise.

Scythe has designed the Kaze Flex 120 PWM to be a very quiet fan. It has two modes of use with consumption of 1 and 1.5w. In the first, always configurable through its four-contact PWM connector, it has a working mode with a minimum of 300 rpm and a maximum of 800 rpm, the most consumption mode reaches 1200 rpm In either case, noise generated by this fan does not exceed 25 dBA.

At these working frequencies this fan will never make a noise that can be minimally annoying, but despite its low revolutions, it is capable of exceeding 50CFM (87m3 / h) of air flow with a pressure of up to 1.05mmH2O.

Its 120mm design fits perfectly into the dissipation block of the Kotetsu Mark 2 through a simple retention system that makes it easy to assemble and disassemble. It also has rubber supports in each of its four corners to avoid the transfer of vibrations to the whole set. The connection is a four-contact molex type, with PWM, and has a 50cm meshed cable.

Mounting system

The Scythe Kotetsu Mark 2 supports mounting on any modern or past processor except AMD TR4 socket processors. Its HPMS III docking system allows its use in LGA2011, LGA2066, AM4 socket processors, etc.

It has a fixing system using rear support plate or, in the case of AMD or LGA2011 / 2066 processors, taking advantage of the socket's own support plate. The final fixing is carried out by means of a central plate that blocks the base from the center and which is regulated in pressure by screws with integrated springs and by its plastic / rubber spacers.

If we are fairly skilled we can mount it in less than 5 minutes and the fixing is solid, without transfer of vibrations and perfectly safe for our processor. The assembly kit also includes thermal paste, although Scythe offers it in a bag that we will then hardly be able to take advantage of, maintaining its properties, in future assemblies or disassemblies. A syringe is usually better to use the thermal paste on several occasions.

Performance and noise

TESTING BENCH
Processor:	Intel Core i7-8700K
Base plate:	Gigabyte Aorus Gaming K3
Memory:	GSKill DDR4 3000 16GB 2x8GB
Heatsink	Scythe Kotetsu Mark 2
HDD	Samsung 960 EVO 512GB
Graphic card	Integrated processor
Power supply	Enermax 500w Fanless

We have tested this new model with a mid-range processor, but at the same time demanding, such as the Intel Core i7-8700K. We have tested it so much in its usual frequencies, always forcing the 6 cores it has, and also with a moderate overclocking of sustained 4.6GHz, which I think is perfectly acceptable for a heatsink like this, which in turn is quite economical.

These are our results:

Interesting results that show us that this model is more competitive than its price could initially indicate. The improvement of the fan, in this generation, achieves magnificent results of stability, noise and sustained temperatures, even more considering that our processor has not had any type of improvement to make it more efficient and that we have used, as always, the thermal paste which comes standard with the heatsink itself.

Worthy successor

The first thing we have to take into account is that this heatsink has a cost of just over 30 Euros, with taxes included. It is a mid-range price within a brand where quality levels are well above other cheap brands. It is a great opportunity to have a great heatsink at a price that anyone can afford.

The performance, however, is somewhat far from the current great heatsinks, but achieves good results, with moderate overclocking levels and controlled temperatures in a demanding processor such as the Core i7-8700k. At the sound level it behaves in an exemplary way so it is perfect for those who have a mid-range processor, over 65-90w, with a moderate overclocking, who seek silence and a very controlled investment.

Final words and conclusion Scythe Kotetsu Mark II

The Scythe Kotetsu Mark II is a heatsink worthy of those lists that we make when we want to mount a good computer, that is silent and powerful, and where we also have important performance restrictions.

We recommend reading our guide on the best heatsinks on the market

As we have seen in our test bench it is capable of supporting the 4.6 GHz in all the i7-8700K cores. Having temperatures of 32 ºC at rest while at maximum performance it reaches 77 ºC.

Without a doubt there are better heatsinks, but you will not find any for the price (37 euros in major online stores) of the Scythe Kotetsu Mark II.

ADVANTAGE	DISADVANTAGES
+ Really balanced price	- We don't have support for TR4
+ High quality fan	- We can only mount one fan
