Cooling solution has been the significant part in PCs. There was time when users were willing to utilized stock cooling solution, the prominent example is Intel stock and still are relying, but when it comes to overclocking the chip, Intel stock only get worse and that’s where aftermarket cooling solution comes in handy. In fact, the presence of Intel stock heatsink is almost ended, especially with the induction of Intel’s Skylake series. Now, every PC has to rely on aftermarket CPU coolers.
CPU Coolers has been divided into two categories; All-in-One liquid cooler and Heatsink Tower cooler, the latter one is being very much matured since it has been here since a very long and in fact, ages before AIO. The main difference between these two are the Looks, design, quality, and technique.
Scythe is a well-known CPU Cooler manufacturer on the market. Started its business operations first in November 2002. Having several categories in its product lineup, CPU coolers have been Scythe’s best-known product line. Not the mention, the Mugen Series air coolers has been working prominent and profitable for Scythe. These days companies are shifting their efforts towards AIO coolers, as they are more in trend now. However, Scythe, on the other end, still has given no sign of trendy AIO coolers on its upcoming list. I hope Scythe would also surprise its consumers with AIO development.
Recently, Scythe has introduced a Mugen 5 Rev.B and replaces predecessor, the Mugen 5 cooler. The main difference is the compatibility with AM4. Mugen 5 came without AM4 compatibility kit, but now with Mugen 5 Rev.B, you will get AM4 compatible kit included in the package. This would be more convenient for consumers, since they don’t have to purchase a separate AM4 kit. So today I am taking a look an interesting Mugen 5 Rev. B CPU air cooler with model – SCMG-5100. The cooler is set to perform as good as the competitors but at much lower noise. The Mugen 5 Rev.B is a heatsink build, comes with a single Kaze Flex 120mm fan with rated 1200 RPM fan speed. A 154.4mm high cooler ensures fitting in every PC gaming/standard case, while 850g weight as a whole. With 6 heatpipes, this cooler is securing a good heat dissipation design. Marketed as mild to high overclocking setup. Let’s find out what it has to deliver.
The Package and The Content
The cooler shipped in a cardboard box, having black as base color while blue accent. The top view is pretty much decent containing Cooler name and model with signature in blue.
Looking at the front, the logo at top right corner, cooler picture at middle and lower has compatible sockets and AM4 sticker. The good thing is, it has a complete support of sockets releases till date. Am4 is a worthy addition to the cooler because the market is getting trending with Ryzen AM4.
Around the sides, some marketing of its own product. Feature images and little description with it. The specification is being listed regarding to cooler. The tabular form exhibits major specification in a multilingual suggesting it is covering non-english consumers as well. Giving the dimension of cpu cooler on box is important as users gets a brief look at the dimension, specifically, the height. Not necessarily significant but it sends a good message in consumer’s mind.
Inside the box, I found a plain white box, probably it’s an accessories box. Just below to it a scythe brand cooler fan lying on the white foam, The CPU Cooler is likely adjusted at the bottom.
Presenting to you Mugen 5 Rev.B cooler.
The accessories are in numbers. In the box, I found complete AMD and Intel’s installation kit. The specifics are listed below:
- 1x Backplate
- 2x Mounting Plates (Intel)
- 2x Mounting Plates (AMD)
- 4x Stud Nuts A (2011-v3)
- 4x Screws (Small)
- 4x Stud Nuts B
- 4x Screws (Large)
- 4x Black washers (2011-v3)
- 4x Steel Fan Clips
- 1x Thermal paste
- 1x Rubber Spacer (775)
A Closer Look
So, looking at the heatsink, it’s a silver color heatsink and has been dedicated for most air coolers. The top plate of heatsink is completely silver with lots of heat pipes ended up on top with a unique round shape design. The Scythe logo is engraved in the middle of the plate as seen on Noctua ones, too.
The Heatsink contains single stack of fins, and these fins looking not too close to each other, ensures enough room to move air. With silver heatsink you’ll see similar kind of designs with competitors, too.
The side of heatsink would tell the half clear story. From this angle, I can see the both side’s design briefly, if not completely. Heatpipes with an offset design offers high compatibility.
The backside of the heatsink has cut off fins which accommodate the quad channel DIMM setup comfortably. The 5 cut off fins, indeed, is a good collaboration in design.
Now looking at the bottom, the 6 heatpipes of Nickel-plated copper has been connected and going through copper base and joining the other side of the stack. It’s not Aluminum base as people are rumoring though, it’s a copper. Here, you need to understand the difference between the having a copper base and aluminum. The copper is somehow better in heat transfer from the contact area, better thermal conductivity but more weight and high cost. In comparison, the Aluminum is usually utilizes to mitigate the cost, weight and so the price. Therefore, Scythe Mugen 5 Rev.B adaptation of copper base and heatpipes ensures better thermal transfer and hence better performance.
Mostly radiators are being centered as per design, but Scythe Mugen 5 heat sink is not centered but slightly offset to the back, allows unobstructed RAM slots, adding a huge credit to the cooler.
The Mounting Bar over the base plate is reminding me of Noctua NH-U14S style mounting bar, which give an impression that this cooler going to get a simple procedure installation.
It comes with a fan, Kaze Flex 120. An in-house engrineered grey and black color fan, having logo in the middle, 11 grey blades, black frame and an anti-vibration pad at each corners.
The fan outputs 1200 RPM as advertised on website, having 4P PWM connector in white, while the power rating is 12V with 0.13 Amperage and consumes a very low 1.56W power. The quality looks to me very good.
It’s time to install the heatsink on the motherboard. First and foremost is definitely the backplate mounts at the back of motherboard. To achieve that, screw tight the backplate by using Stud Nuts B from the front, slightly different than other coolers.
Next are the brackets. Take the Intel’s Mounting Plates, place them on Stud Nuts B and tighten them with small screws from each ends. These plates will be used to grip the cooler’s Mounting bar afterwards. Also, thermal paste applied with a dot technique. FYI, users can utilize any kind of application technique because more or less all works with same results. But the benefit of dot method is that it would spread the compound evenly on the chip by cooler weight.
Now CPU Cooler is landed on the chip and to fix it, screw tight the Mounting bar by using screwdriver. Here, screw at the front side of heatsink is simplest, but the screw on other side requires a long screw driver because it resides exactly under the heatsink. Don’t agitate, just make sure you have one longer size screwdriver in your equipment box.
Finally, installing the fan on front by using steel fan clips. Going to admit here, those clips are pretty much same as the Noctua ones, which, in my opinion, are better as it ensured an effortless mounting.
So, in the whole installation process, I found the installation was simple, but backplate mounting was very interesting. The fitting of backplate gripped from the front by using Stud Nuts B is, indeed, an effective in terms of recede steps, however, before that I had to figured out the appropriate screw hole for 1150 socket. Once I got one side gripped well, the other three sides became piece of cake. With the instructions being followed on manual, it didn’t take me long to complete the process. Overall, heatsink installation was easy.
Clearance & Compatibility
Air coolers have been victims of slots clearance issues, especially when it comes to DIMMs. The dual towers has been very in on this issue. But, looking at the Mugen 5 Rev.B cooler, the DIMMs clearance is absolutely spot on. The offset design of heat pipes offers an unobstructed business with the DIMMs first slot. After installing the cooler, I discovered that the distance between the RAM and cooler is around 2-3mm or under 0.5cm which is so satisfying. Just get as many rams as you want populate all of your DIMM slots with no worries. On the other end, there was a good enough distance between the PCIe and the heatsink’s stack. Scythe designers best thinks for consumers.
Test Bench & Performance
For this specific review, I picked an i7 4790K, a 4th generation INTEL processor, on an ASUS Maximus VI HERO motherboard. For high quality testing. Manual BIOS settings have been used. Further, I utilized Noctua NT-H1 thermal paste, a renowned thermal compound for a high overclocking system. All the test conducted under current ambient with +/-1 margin of error.
ASUS Realbench 2.21 – Stress CPU has been used for the cooler to be tested on an extra high load. This program can tell the capability of CPU can go on high, of course under extra-normal loads. All the test ran long for 15 minutes and it’s good enough time to probing and getting desire results.
Using Delta temperatures (Ambient – temperatures) = Delta T
- Noctua NH-U14S Air cooler (Single fan)
- Reeven OKEANOS RC-1402 Air cooler (2 fans)
- SilverStone TD02 LITE AIO cooler (2 fans)
All the coolers being tested with 100% fan(s) speed.
Price: 47 EUROS ($55 US Dollar)
- High Compatibility
- Very reasonable price for performance cooler
- Less height (PC standard case would afford it)
- Extremely Quiet even under high load
- Not the best finishing on the aluminum fins
The Mugen 5 Rev. B is a new induction to the series of Mugen coolers. The design from the predecessor has not been changed a lot but comes with one less fan. The latest design is something that would help users to populate more DIMMs than just restricting due to obstructions. In addition, the compatibility and clearance has been abstoutely exceptional. With offset heatsink design, the obstruction is unarguable now; making ways easy for the consumer to decide on an appropriate cooler. I haven’t tried this cooler on Quad channel motherboard, but I am pretty damn sure, the cut off fins from bottom would be far more helpful for installing heighted RAMs. The tolerance level is simply gone better. Not to mention, the support for future sockets is significant, too.
Next is the performance. Well, I am in the position to say, Mugen 5 Rev. B has been great across the tests. On a thermally hot chip, Mugen 5 is able to restrict the thermal performance and restrict CPU at 56C on overclocked. In charts, it lost the competition by only 2C, but stand better than Noctua U14S, indeed, a very convincing output. Not to mention, the fan speed peaked out at 1150 RPM (+/- 10) with hardly any noise replication. I must conceal that all the rumors I heard about Scythe’s cooling fan being silent, is very much true. With that being said, high RPM fan would lead to noise increment, but, nevertheless, you’ll have a secure spending.
Mugen 5 Rev.B is retailing at 47 Euros (55 US Dollar). I think the price for this cooler is perfectly placed. It looks might be different, but, indeed, who look for price/performance, with an option of adding another fan, that’s a valuable deal. This cooler is as good as Noctua ones when it comes to noise and silence operations. I would recommend this cooler to users who are looking for good thermal performance, ultra-low noise and compatibility at much lower price than competition.
Also, You can order Mugen 5 Rev. B from Amazon.
I am thankful to Scythe for providing me review sample for the test.
