Scythe Mugen 4 CPU Cooler
Out of the box, the Mugen 4 starts at the top with the knurled caps covering the pipe tips just atop the layering of 50 fins. Looking between the four towers, you can see there is a mix of four off and four on to connect the sections together with the fins. You can also see the two directions the pipes are bent to allow for the staggering of the pipes through the cooler.
This side shows just a slight crush of the fins at the top, but that can be adjusted later. What I want to show now is the pair of thin grooves near both the right and left edges that allows for a fan to be placed on either side of the Mugen 4.
Looking at the width from a slight angle shows much better how the fins are sectioned off to form four sections with three sections of the six pipes running into each section to allow the fan and fins a much easier time of spreading and removing the heat from the CPU.
When the side of the cooler is shown on a similar angle, you notice that the sides are virtually flat, and beside the grooves for the wire fan clips, there are a pair of V grooves cut into the sides of the fins for nothing more than aesthetics.
When looking at the Mugen 4 from the top, there is no doubt now what I meant about the four sections of fins. Even though the center two are tied together much closer than the outer two, there is some very unique shaping going into the leading and trailing edges. Another thing I like is that there is no branding, so the cooler is right any way you install it.
Flipping the Mugen 4 around, we are now looking at the six copper heat pipes. Once they leave the base some are gently bent to make the outer fins section, while the others have S bends and are set near the center. At this point all of the aluminum fins are then pressed onto the pipes.
As the pipes meet at the base they are squeezed tightly next to each other, and get slightly flattened out with the two piece copper base, as they add pressure and are soldered into place to make one solid unit.
Scythe does take some time to finely polish the copper base plate before it is nickel plated, offering the reflective quality you see in this image. The majority of this base is flat, but at the edges and the corners there is some deviation away from the IHS, but well outside of the contact area.
Adding the 120mm fan was pretty easy, and looking at the both of them together, from the front, you can see the fan stands as tall as the caps and will also blow air under the fins. This way, not only do you get more clean air over the fins, you also get some blow by to cool motherboard components as well.
With just the one fan on the Mugen 4, it definitely adds some thickness to the cooler, and from the looks of things, it will likely play up with the memory too. Imagining a second fan on here would make this cooler would jump from 88mm wide without a fan to 138mm with two attached.
