Even if you're not on a budget this should be your go-to cooler!

Reviewed in the United States on July 5, 2020

I was looking for an upgrade from my Wraith Prism cooler that came along with the 3700x. The Wraith works well enough, but it is a loud, top down style cooler that I'm not particularly a fan of. The installation was straight forward as you don't need to swap the back-plate if you are coming from an AMD cooler. Just four spacers and two brackets and the cooler is ready to be installed. The screwdriver that comes with the kit is easily valued at $5-10 and is actually a legitimate tool that any hobbyist or tinkerer would be happy to keep for future use. I used Arctic MX-4 thermal grease since I had it on hand. I might recommend getting an aftermarket thermal paste, not because I doubt the performance of the paste that comes with the kit, but I was not able to control the flow very well due to the "stickiness" of the syringe it came in and couldn't get an even application like I can with the MX-4 syringe. The cooler is easy to seat and the screwdriver makes securing it evenly effortless. The Scythe fan is excellent! It comes with vibration dampeners pre-installed, an extra set of clips for a second fan (for push/pull config) if you so choose, and it is extremely quiet! Once the cooler was installed I took about five minutes just to stare at it because it looks great! The caps that they put on the end of the heat pipes (of which there are six) look awesome and overall, it is an aesthetically pleasing design. Unfortunately, the room that my PC is in gets hot do to a lack of AC and it is currently summer in Texas. This was one of the reasons I decided I needed to upgrade to a larger cooler. At its hottest (and during the time of my stress test) it gets anywhere from 80-85F in the room which is hotter that most would ever keep their PC room especially if they had a choice! My case is an NZXT H510 Mid case with 2x140mm fans pushing and 2x120mm fans pulling. I ran the Prime95 stress test for an hour and fifteen minutes at a 3.9GHz overclock, at the hottest time of the day in my room. The CPU temp never went above 73C, Max fan speed was 1130RPM and during that time it was never any louder than my old Prism cooler at an idle temp speed, I could barely hear it honestly. This cooler was ~50 bucks... There are plenty of 80-100 dollar coolers out there and I wouldn't recommend any of them over this because that ~1-2C degree difference you MIGHT see isn't worth paying extra for in my opinion. Solid quality, unbeatable value, and dead quiet...

I wanted a better cooler for my ryzen 3600 than the stock one and some how I ended up finding this and purchasing it. It was cheaper than the high end ones, but still felt like it would do a good job for its price.
My high temps dropped from 90 to 80, and idle was a lot cooler too. Recently upgraded to a 5800x3d and this cooler works perfectly for it. I added a 2nd fan (a kaze one with same RPM but slight different CFM but no issue there) and I think I even underused the paste, but it was still enough where playing games I never go above 70 degrees celcius, and it only hits 90 when doing really intense stress test. Most benchmarks keep is down to 85 at max (and I live in Florida, AC not always on blast). 5800x3d is a hot CPU with the l3 cache, but this cooler does great keeping it cool and undervolting helps temps on the 5800x3d a little.

The best thing about this cooler was how easy to install it was. I wanted a cooler where I didn't need to mess around with crazy brackets and such, and this one has a couple but they are very easy to install compared to most other CPU coolers I saw. It includes a nice magnetic screwdriver as well. It is pretty quiet, but the 2nd fan I added made it a little loud when running at full load, but honestly not that bad and you might not need to run it at full RPM like me (florida).

Cooler than cool and you can add a second fan! (I did ... and then built a second PC for myself)

I use this cooler with my Ryzen 7 3700X CPUs and I added an additional fan (Noctua NF-P12 redux-1700 PWM, High Performance Cooling Fan, 4-Pin, 1700 RPM (120mm, Grey)) on the other side of the heat sink. Neither fan is noisy at all. I cannot hear them over background noise. This cooler is tall, so check your case width. It does have an off-center mount so the heat spreaders on my RAM do not bang onto the cooler spreader. So far, I have not had any problems with the Myugen on either of my builds.

Oh! And it comes with a screwdriver and thermal compound paste

Pros: Really cool (literally and style wise)
Not loud. Even with a second fan. (I also bought Noctua NA-SAVP1 Anti-Vibration Pads for 120/140mm Fans)
Offset cooling Heatsink clears RAM modules (check your own ram height requirements)
FREE mounting screwdriver for the mounting screws. (And a very nicely made one - you know like how they USED to make them - clear handle, weighted shaft, slightly magnetized tip, solid tip that does not shred when trying to screw in a screw, etc.)
AMD (AM4/Ryzen) and INTEL (LGA151) mounting hardware included (check your CPU/MB specs for compatibility)
Fantastic price.
You won't have to be afraid of a water cooler accident in your PC.

ADVISEMENTS (Not CONS, because I love this cooler):
It is tall, so check your case.
If you have tall heat spreaders on your RAM, check your specs.
It is heavy, but the motherboard and case backplate support it well. Just be careful. I did not see any undue stress when mounting either of my Scythe Myugen Rev. Bs in either build, but make sure you have the motherboard standoffs underneath to support the weight.
You may find yourself giggl...er... laughing at how easy to install and wicked this cooler looks on your board. I did, and almost drooled on it. Almost literally drooled.
No lights on the stock cooler or fan for flashy RGB fanatics. Flashy colours aren't my thing, but FYI in case they are yours.

HIGHLY RECOMMENDED!

Excellent cooler, definitely worth the cost.

I bought this to replace a Be Quiet! ... Pure Rock 4? Or something like that. The Be Quiet! cooler was fine overall, but it was difficult to install. (The mounting bracket was rather poorly designed for AM4)

I bought this after I did a CPU upgrade and struggled a great deal just to get my Be Quiet! cooler back on (and not in a way I was confident).

Installation was a breeze and my temps are nice and low. As I type this right now my 3700x is sitting at a balmy 45c while I watch a stream on one of my other monitors. The Mugen is a very nice performance cooler without any extraneous features or gimmicks.

Great PC air cooler for an affordable price!

After 2 years it was finally time to send the stock AMD Wraith Stealth cooler on my Ryzen 5 5600x out to pasture. They are decent entry-level coolers included with some new processors, but I was very dissatisfied with their overall performance, even after proper, quality thermal paste re-application. I don't even overclock my CPU, I just wanted it to run more efficiently and generate less heat. When it came time to look at a replacement, this cooler came highly recommended by the PC gaming community on Reddit and Facebook.

The Scythe Mugen 5 is a great, affordable option for air cooling. It was super easy to install and came with all the tools/instructions you need. It even came with a little tube of thermal paste, which saved my behind upon installation, because I realized I'd lost my trusty XTM70 paste. While I'd have preferred to use my own paste, it was nice to know I have some that will tide me over until I upgrade my CPU down the road. There are tons of mounting options for this cooler as well, depending on the CPU socket, so just read the product description and ensure it'll fit your board.

As for the numbers, I immediately dropped a whole 20c at idle (from 50-30c) which was pretty wild, but what really amazed me was its performance in intense gaming. In demanding titles like Red Dead Redemption 2, Battlefield 2042, and Modern Warfare 2, I regularly saw my CPU hit 95c with the Wraith cooler. After installing the Mugen 5, now it doesn't go above 60c (on average.) That is an insane 35c drop in temperature, in real-world gaming scenarios. I didn't think changing out to a more robust air cooler would entail such a HUGE difference but I'm glad I made that leap! I can game with confidence knowing my rig will handle whatever I throw at it, and when it comes time to upgrade, I know I'll be in great shape.

This is the real deal

I'm very much in the mindset with PC hardware that "if it sounds too good to be true, it is" - as it seems many other reviewers are here. But this cooler is AMAZING, possibly the best bang for your buck you're going to get on air.

My system is a Ryzen 5 2600X with no manual OC, just whatever the automatic turbo boosting feels like doing. It gets the job done, but I was getting kind of annoyed at how toasty it could get at times with the stock cooler. TO BE CLEAR, the stock cooler with all Ryzen systems is 100% absolutely fine if you don't overclock, but I may be upgrading later and wanted to have a good cooler on hand for it.

The installation of the fans isn't very well described in the manual (they're like spring clips, you have to pull them into the cooler), but otherwise it was a painless, straightforward install. I did overtighten the cooler which resulted in my system not doing anything (I'm guessing I managed to tilt the CPU JUUUUUST enough to get the pins off the pads in the socket) but loosening and retightening fixed it. Knocking a star off the mounting system for a combination of those two things.

Otherwise, it's a dream. I bought a second fan to do push-pull through the cooler (probably unnecessary) and the temps are great, even with my shoddy thermal paste application (which frankly I'm not worried about, will probably go back in with some Grizzly if it seems to be an issue).

Before (Ryzen stock cooler):
idle 45.9c
prime95, 5 minutes - 88.8c @ 3.77ghz

after:
idle 37.3c
prime95, 5 minutes - 75.4c @ 4.22ghz

I honestly don't think you're going to do much better than this without liquid or an exotic air cooler. I used to be a big fan of the Hyper 212 from Cooler Master, but despite this being a touch more expensive, I think this is my new favorite budget cooler.

Unbelievably underrated

After having nothing but nightmares with my Ryzen system I ditched Ryzen for Intel again with a 13700KF. My older cooler didn't include socket 1700 mounting hardware so I had the perfect excuse to get a new cooler. I originally wanted to get a newer fuma 2 (I had an older version of it) but it was out of stock and not wanting to hold back my new build, I went ahead and got the Mugen 5 black edition. I was a bit nervous if it was going to handle my 13700KF but my fears were unjustified. The Mugen 5 does a wonderful job keeping my 13700KF cool! Even during turbo boost 3 duration boosting were it chugs down 250ish watts of power the highest temperature recorded was 93c. Below the 100c max. Under normal operation, long sustained loads were my 13700kf is drawing 120-150ish watts of power, the cooler keeps my 13700kf in the 60-70c range. In games my 13700kf is around the 50-70c range. At idle it's in the 20-30c range and light loads like web browsing 30-40c range.

Considering this is a single tower, single 1500rpm pwm fan, cooler for $65 I'm more than impressed and happy with how much heat it can handle!. I don't know how much better the fuma 2 is but the Mugen 5 is more than capable and it is nice only needing one fan instead of two. Not having that center fan that's wedged in the middle makes it a lot easier to clean. And the Mugen cools so well while being extremely quiet with just the one fan. It's a big cooler while at the same time manages to not take up so much space like magic. It doesn't block any ram slots, it's black finish looks amazing, it's cooling potential is strong enough I would feel comfortable using it on a 13900ks, and it's affordable. What more could you ask for? Everything scythe I have used so far has been top notch.

MUCH better than AMD's Wraith

Reviewed in the United States on May 19, 2020

Verified Purchase

I have a AMD 2700x processor using the standard AMD Wraith cooler it came with. While the general consensus is that the Wraith is an excellent cooling solution for AMD processors, it struggled to keep up with my more advanced and CPU-intensive processes. Rendering movies and iRay images. My graphics card is up to that challenge, but the 2700x with the Wraith would peg the 85C TMax rating for the Ryzen 2700x, and stay there for the whole rendering process. That could take up to an hour, depending on how long the video was or the details and materials used in the images.

I needed more cooling.

So, after reviewing a lot of different fan/heat-sink combos, I found this Scythe Mugen 5. I have NEVER seen this high of a rated computer-related device in 25 years of buying them, let alone a COOLING solution (which typically get very mixed reviews).

I had a similar model of cooling in my old computer for the older gen i7, but since that went to my wife, I couldn't transfer it to my new rig. The price was excellent for what you get.

It contains all of the mounting hardware, including a very decent magnetized screwdriver (which is necessary for the way it's mounted, since access to one of the screws is through all the cooling fins from the top down).

Installation had a hiccup that didn't actually involve this cooler (my CPU was glued to the Wraith, and I spent several hours straightening its puns and cleaning the socket after I manged to carefully pry it off of the Wraith). Once I was back up and running, there was a noticeable 8C drop in the idle temps from mid to upper 30'sC to upper 20'sC with an ambient air temperature of 75F (sorry for the different measurement systems). The air flow was now linear instead of perpendicular to the flow, which helped the cooling issues as well.

So at least I knew the Scythe was doing a much better job pulling heat off of the CPU.

The acid test came later in the day when I had a complicated image to render. With the Wraith, I usually hit 85C within the first 45 seconds, and it would take about 18-25 minutes to render. When the rendering ended, you could hear the Wraith spinning down, but it never went below 40C for five minutes.

With the Scythe, it never went above 80C, rendered for 15 minutes (four of which was at 80C), and it took eleven minutes to hit that mark. Cool-down was back to upper 30's within 60 seconds.

80 is high, but not damaging high. 85 is where you don't want to hit, and my CPU did hit 86 with the Wraith once (without shutting down). I suspect it throttles the load to keep from exceeding the temperature limits.

So, the cooling was substantially better overall and well worth the money.

In a side note for those who might use AMD's Wraith, a few words about it's failure to live up to the reviews that factors into why the Scythe is so much better.

The Wraith is a 4 heat pipe cooling system mounted flat to the motherboard. It comes with paste preapplied in a decently flat layer. It's very easy to install. However, after it came off, I noticed "lines" in the paste on the CPU and on the Wraith. It turns out that the heat pipes on the Wraith are not ground to a flat, polished surface. There are distinct height differences between the heat pipes and the copper in which they're embedded.

In order to transfer heat efficiently, the surface against the CPU should be perfectly and completely flat and even. Thermal paste only goes so far in ensuring that the heat is transferred, and will not live up to the task if it's too thick in places. An eyeball estimate for the amount of surface with thicker paste on the Wraith is about 7-8%, or about the same difference in the cooling I had through the Scythe, which has a very highly polished and flat surface for placing against the CPU (remember to remove the protective film on it before installing it!).

My sense is that the Wraith could be a lot better if the surface was flat and polished even and smooth with no lines. And that's probably why there was a such a major temperature difference. As the paste aged, it became less able to transfer heat, leading me to needing a new cooling solution.

I'm quite pleased by the quality and performance of the Scythe. Had I seen the Wraith's CUP surface below the paste on it, I would NOT have used it in the first place. Hence why I'm also reviewing it here. If you're considering a new computer build with an AMD processor, if you plan on doing high-end, CPU-intensive things like throttling, video/graphics rendering, or other such things, DO NOT use the Wraith, and get this instead.

You will not be disappointed.

Reduced max CPU temps from 65F to 32F, will not go over 32F now. Very nice mounting system for both AMD and Intel, with picture instructions, and a very long screwdriver that accommodates the mounting of 1 screw through the cooler. Superb system overall.
