FEATURES:
F.M.S.B. (Flip Mount Super Back-Plate)
The newly developed F.M.S.B. (Flip Mount Super Back-Plate) both improves the compatibility and mounting of the cooler with the motherboard. With this system, a solution was developed which is not using push pins but is instead based on a Back Plate/screws mounting set. Of course, Mugen 2 is compatible with all the current sockets, including the new Intel Socket LGA1366.
Multi Fan Mount Structure
As with the former Mugen it is possible to mount the supplied fan in four different directions. By this, the user can arrange the air flow to the circumstances of his deployment area. Furthermore, a maximum of 4 fans be installed, the needed fan clips have to be bought separately.
M.A.P.S. (Multiple Airflow Pass-Through Structure)
The newly developed M.A.P.S. (Multiple Airflow pass-through structure) is a completely new lamellar structure, where the airflow generated by the Scythe Slip Stream 120 mm PWM fan can be used perfectly

Great Cooler, However needs proper installation for optimum cooling performanceJan 24, 2010
Used this cooler for a core i7 920 processor. The installation is time consuming. The cooler and the backplate sandwiches the processor and the motherboard. This allows the cooler to be attached to the processor tightly. However, I had an issue with the initial installation. I didn't want to apply too much pressure to the screws on the backplate fearing I might damage the processor (>$200) or the motherboard (~$250). Ran the pc, and the cpu temperature was pegging at 50ºC from start up and the core temperatures were at >70ºC (when idle!). Had to take out the motherboard (and everything else connected to it) and tighten the screws quite a bit. Now the cpu temperature is 24ºC on idle and 45ºC when running Prime95 for more than 8 hours. The core temperatures are 35ºC-40ºC on idle and around 51ºC-58ºC on Prime95 for more than 8 hours. I had a nervous time tightening the screws at the back without any way of knowing when to stop. I also had to eyeball the end of the screws on the cooler side of the motherboard to tell if the screws were tightened equally. (Don't know if this is my inexperience assembling pcs!)
Some documentation about how much to tighten the screws, or a way to control the maximum tightening possible on each type of motherboard by not having threads beyond a certain point on the screws would have gone a long way in assuring a smooth installation. Also, some foolproof mechanism to tighten the four corners equally would be great.
The enclosed fan is good, and silent. Overall, I am definitely satisfied with the cooling performance.
 GREAT cooling, pain in the butt and hugeDec 14, 2009
This seems to be a fantastic cooler. It's quiet and supports a variety of sockets, but I have to subtract a star for the cons.
Pros:
* Great air cooling
* Quiet
Cons:
* Pain to install (the most complicated cooler I've ever installed). Requires removal of back plate and installation of a new one.
* Huge - requires careful thought of how to install.
Other notes: I installed the heat sink on the MB before installing the MB into the case. I carefully had to think about how to install the heat sink and fan so it would fit with my EVGA X58 132-BL-E758-TR motherboard and blow air in the proper direction. I even had to install a couple of sticks of RAM before installing the cooler, because I'm not sure if I would have been able to with the heat sink in the way.
Great pedigree, mounting the fan is an adventureOct 28, 2009
Works as advertised, but I haven't pushed my i7 920's much past 3Ghz yet.
To install by yourself, or even with help, your motherboard must be removed from the machine completely (or even better, fresh out of the box). For the final mounting step, I recommend you turn the cooler upside down on the work surface, and mount the motherboard onto the cooler, as opposed to trying to mount the cooler onto the motherboard. You can use the box it came in as a support or jig for one edge of the motherboard, with the cooler basically holding the whole works in the air.
Do a first pass (lower the mobo onto the cooler plate) without screwing in the fasteners, and then check your grease coverage. It probably won't be even. Adjust the angle of the heat sink to make the most flush contact with the CPU possible (i.e. the most even thickness grease print). Assure grease coverage is adequate. Use Arctic Silver. Use a magnetic screwdriver to drop the screws into place without dropping the screws into irretrievable places, and tighten while holding the angle of the cooler to the mobo constant.
The fan is a pain to hook onto the cooler. When re-assembling, do this step last.
And make sure it fits in your case before you do anything. The manufacturer has a compatibility list, and the given measurements are spot on.
Works well for i7Oct 17, 2009
No kidding that this thing is hard to mount, as it took me 1/2 hour to mount it (I took time to do it right). The instruction could be more helpful if Scythe provide more step-by-step diagram of what goes where and what goes in first.
I was worried this thing would not fit in the Antec Sonata III "Quiet" case (my MB is an ASRock X58 Extreme), but it fit just fine. My next worry was it would block the RAM slots of the X58 underneath it, but it didn't block. This thing was raised high to give enough clearance under it, and I was able to install my 3rd bank of RAM with no issue (just make sure you install your RAM before snapping this "little" baby onto you MB. I believe the 6th bank of RAM would fit in as well as I see it still has enough clearance as well.
I installed the Scythe fan so that it would blow into the heat sink, and toward the chassis fan in the back, which of course sucks the air out. Not sure if that is the ultimate config or not (to my opinion, it's probably the right config). The fan is actually quite quiet and can be clipped on easily.
As a side note: the chassis fan that came with the Sonata Antec III Quiet case wasn't by any mean quiet, even at the lowest setting, and I had to replace it with another Scythe fan. As of now, I'm still wondering why Antec would put such a noisy fan in its "Quiet" case. The Power Supply that came with the Sonata III is actually quieter than even the Scythe CPU fan.
I'm running my i7 920 (2.6GGHz) at between 3-3.4GHz overclocked speed (didn't want to overclock with the stock CPU fan of the i7, and don't want to get too greedy with the overclocking). I've seen CPU temp rose to over 60-C on warm day (when people tell about the CPU temp, they never mention the room's temperature which is a very important factor which affects the CPU's temperature greatly -- they should at least give the outside temperature so people can get an idea of the relative environment). On warmer days, I usually tuned down the overclock speed a little bit to be safe (the X58 Extreme comes with a Windows-based Overclock utility that you can adjust the OC parameters on the fly, while in Windows).
From what I read (and what the Core Temp utility indicates), the max safe temperature for the i7 is 100-C, so even at 60-C my CPU should still be running ok. As of now, it is 68-F, and Core Temp reports 43-C, 42-C, 42-C, 41-C for all 4 cores running at 3.2GHz.
After 3 weeks of usage, I believe the Scythe Mugen 2 is a keeper, as it's not too expensive, comes with a decently-quiet fan, and provides adequate-to-good cooling performance for a reasonably-overclocked i7 920.
My main use of PC is computer recording. It's why I care a lot about background noise from the PC.
Superp!Oct 04, 2009
All I can say is congratulations to the designers as they have made a truly fantastic product. I bought it because I didn't want to buy small and cheap then have to buy again later. I am using it in a Coolmaster Sileo case with a Quad Q9550. It does not need the fan! It sits right in front of the case fan and below the PS fan. It is running now at 36C in room temp 25. I managed to get it up to 50C full load but that was the max. Cheap for what it does. So good.
My thank to the guys at Scythe!
