Scythes Mugen cooler is regularly updated, the Japanese manufacturer has recently introduced to the market a new generation. Sample Scythe Mugen 5 just arrived in our test lab.
Ten years have passed since that moment, when the company introduced the first cooler Scythe Mugen. Initially, it was called the Infinity or Infinity SCINF-1000 he had already attracted the attention of impressive size. Simultaneously, cooler pleased the high performance and relatively low price. Later, competitors introduced new models of tower coolers with 120- or 140-mm fans, so the pressure on their part to Scythe become stronger. In response, the Japanese manufacturer began to produce updated Mugen model.
In 2016 introduced a new cooler Scythe Mugen 5. Like its predecessors, Mugen fifth generation refers to the wide tower models with a single radiator. But compared with Mugen 4 radiator has been changed. Suspicious “notch” in the past. Design radiator Scythe Mugen 5 has been optimized to ensure maximum cooling performance and better compatibility with straps memory. Here Scythe had to choose an asymmetrical design. Stock cooler is equipped with a 120-mm fan PWM, namely Kaze Flex 120 PWM. Unlike GlideStream fan from Mugen 4, it uses vibration isolation with rubber corners. There have also been changes in the installation process. Scythe offers new HPMS II mounting system instead HPMS (Hyper Precision Mounting System) at 4 Mugen.
For a single tower cooler recommended price of 47,95 euro does not seem to be low. But still should wait for the cooler on the market.
Before we move on to testing, let me give you the main Scythe Mugen 5 spec in a tabular format.
Scythe offers quite a generous package. The user will receive not only a multi-lingual manual and necessary accessories mounted to the metal back plate, and a syringe with thermal paste of Scythe, two pairs of bindings for the possible push-pull configuration of the 120-mm fan and a Phillips screwdriver. Without a long-bladed screwdriver is required because the need to tighten the fixing screw in the center of the cooler.
The cooler itself Scythe Mugen 5 seems pretty simple. In the heat sink is no longer cuts conspicuous predecessor, Scythe also refused to bright colors or lights.
If competitors are experimenting with intersecting ribs and cunning forms the Scythe simply imposed aluminum fins on each other. In the center of the radiator can see two “ventilation shafts”, which provide ventilation between the ribs. In addition, one of the holes used to install the cooler.
Staples mounting fans are inserted into the vertical slots on both sides of the cooler. Side clearly visible asymmetrical design Scythe Mugen 5 to improve compatibility with memory. Here, the Japanese manufacturer also should be a fashion trend in the market. Radiator memory offset from the slots to the rear wall of the housing. But precisely for this reason that Scythe had to move one of the heat sink directly under the mounting screws. A second screw is accessible from the outside.
Scythe paid appearance not so much attention, although the ends of the heat pipes capped. On top there is even embossed logo Scythe.
Another view on the radiator also emphasizes the asymmetrical design. It is clearly seen that a “serving” side Scythe shortened lower ribs of the radiator. This step allows you to avoid compatibility problems with VRM heatsinks and memory modules to the left of the socket (for Intel LGA 2011-3 platform), despite the asymmetrical design. The manufacturer indicates the possibility of a memory strips up to 55 mm. Bottom Scythe has traditionally chosen a nickel plated copper base, the same applies to the heat pipes. Six 6mm heatpipes conduct heat from the base of the cooler to the radiator.
One of the innovations of the cooler – Fan Kaze Flex 120 PWM. Scythe continues to use one 120-mm fan, for some reason, ignoring the 140 mm model. However, a larger fan is unlikely to fit, given the relatively low height of the heat sink – for this reason we had to limit ourselves to additional tests with the standard 120-mm fan. The new fan has several advantages. PWM range is from 300 to 1,200 rev / min. Of course, many users complain about too low maximum speed. But Kaze Flex 120 PWM quiet running even at maximum speed. The advantages we assign and rubber corners. fan vibration isolation This solution is very user-friendly. With regard to the internal characteristics, FDB-bearing ensures a lifespan up to 120,000 hours.
Staples fan is also very user friendly. They firmly cling to the fan and do not slide, the center brackets are attached to the radiator.
Finally, HPMS II installation system we also pleasantly pleased. The first step should be to fasten the sleeve front of the motherboard to the metal plate at the rear. Then, on the sleeve installed two mounting brackets. Finally, the cooler is attached bridge.
But the final step to install the cooler – the most difficult. Tighten the screws on the bridge are biased. The first screw should be tighten enough to he held under spring load. But it can not twist, or a second twist screw will be impossible. In fact, here we have the usual arm with two screws on the opposite shoulder. But then the cooler is securely held in place. Asymmetrical design, we also liked. Scythe Mugen 5 leaves sufficient space for the fan, which is located just between the cooler and the memory slots.
200-mm frontal fan worked with an acceptable noise level, because we switched it to 7 using an adapter. The rear fan we left at 12, so he moved on a constant rate of 1,100 rev / min. It is possible to achieve a reasonable balance between sufficient cooling performance and an acceptable level of noise the fan housing. And our test conditions as close as possible to reality. Too much to reduce the speed of the fan housing is not worth it, because then the body will accumulate too much heat.
We conducted noise measurement using the VOLTCRAFT SL-400 at a distance of 20 cm from the left side of the chassis. The case itself was soundproofed assembled and closed. Room temperature we normalized to 20 ° C, under this we checked the temperature using infrared thermometer VOLTCRAFT 800-200. During each stress test we were recording the temperature, the cooler had to endure a 30 minute run Prime95 (we used a rather “heavy» Small FTT test). The temperatures for the entire test period were recorded in CoreTemp tool magazine, and then we calculate the arithmetic mean of maximum temperatures (less deduction of the difference with the normalized room temperature). Him we shall be entered in the diagram. As we took thermal paste Arctic Evergreen MX-2. We spread the thermal grease on the CPU surface using WLP blades.
Here are the tools that we have used in the tests:
All measurements are in degrees Celsius.
As we expected, the maximum speed of 1,200 rev / min resulted in a relatively small noise level at full speed. cooler work was barely audible, and the only noise was noticeable airflow. At 1,000 rev / min Kaze Flex 120 PWM worked somewhat louder than the others fans. Finally, at 600 rev / min Scythe fan was difficult to hear our Sound meter showed 31.2 dB (A). Further reduction rate of 300 rev / min resulted in no appreciable effect. So Scythe Mugen 5 is suitable for users who need a very quiet air cooler.
The following test scenario, we evaluate the performance of the cooler with the standard fan at 1,000 rev / min and at maximum speed.
At first glance, Scythe Mugen 5 occupies a middle position in the cooling performance. But we should remember here what type cooler in front of us. Of course, Scythe Mugen 5 gives CBO closed-loop and close-air coolers with two radiators. But among single tower cooler Scythe model still takes the lead. An interesting result at full speed. There Scythe Mugen 5 competes with single tower coolers, equipped with a high-speed or large fans. Therefore, we really liked the balance of cooling performance and noise level.
To compare “pure” performance coolers without affecting regular fans, we equip all our reference cooler fans. We used a powerful fan Noctua NF-A15 PWM, the distance between the mounting holes is 105 mm, speed – up to 1,200 rev / min. If such fans can set on the radiator was absent, we used a more compact Noctua NF-F12 at a speed of 120 mm to 1,500 rev / min. In the case of coolers, designed for “real” 140-mm fans with hole spacing of 140 mm, we used the NF-A14 PWM.
Scythe Attachment for fans and space constraints allow only install a 120 mm fan reference. Therefore, we have limited our tests NF-F12.
1.000 / min gave reference fan slightly lower temperature. As a result, Scythe Mugen 5 moved slightly higher in our tests. With regard to test for 600 rev / min cooler it seems to be more sensitive to low rotation speeds than model Thermalright Macho. With regular fan performance drop is not as strong as with the reference: Fan Cooler Scythe Mugen 5 showed 58 degrees Celsius to 600 rev / min, taking up a position above the average.
The cooler Scythe Mugen 5 changed only figure in the title, but in front of us an updated and improved version. The Japanese manufacturer has added innovations in three key areas: compatibility, fan and mount, so the novelty is welcome.
Unlike its predecessor, the asymmetric design Scythe Mugen 5 allows the radiator to the CPU socket on the right side does not interfere with the high memory modules. Therefore, in our test system of any restrictions on the DIMM radiator height was not. Regarding LGA 2011 platform (3), there is left on CPU socket can install modules average height. The fact that the lower cut edge of the radiator, which improves compatibility with radiators DIMM left. Certain improvements we got the fan vibration isolation and fastening the latter, as the staples are used the new format. As for the convenience of the cooler installation, the progress is not so great. But the setting is still pretty user friendly, except for the tightening screws of the radiator bridge.
All these improvements make it easier to work with cooler Scythe Mugen. With regard to the cooling performance and noise level, due to lack of a precursor in our test lab to perform the comparison is problematic, but in comparison with competitors cooler Scythe Mugen 5 showed convincing results. For single tower cooler we got a decent level of cooling performance, but it remains relatively quiet. Even at full fan speed the noise level is tolerable. The lower speed threshold (PWM) is reduced to 300 rev / min, so the cooler is suitable for quiet systems.
In general, Scythe Mugen 5 seemed to us balanced. Although the price compared to the competition is quite high. But at our disposal it was only the recommended price, so you should wait until the cooler in retail.If you follow the recommended price, the market is a single deserving tower coolers are much cheaper. The Direct Macho Thermalright , for example, will save about 10 euros, although it provides comparable performance. On the other hand, for a fee Scythe Mugen 5 gives a more balanced set of features with a quiet fan, a more expensive appearance, and mount the cooler more user friendly. If you need maximum performance, then pay attention to coolers with double sink, the same Noctua NH-D15S .
Mugen Cooler fifth generation showed strong performance results and the noise level is very worthy single tower cooler in front of us. Therefore, we award our Scythe Mugen 5 award “Excellent iron.”
