It seems the Scythe Mugen 2 is a great cooler, plus it is Cheaper then the Zalman Performa I was thinking of buying. Now, I searched for videos about the Mugen 2, one said that the Fan comes with a Speed Controller. Will I need a Speed controller Drive thing to be able to use the Mugen 2? Or would I have to get another 120mm fan?
Scythe Mugen-2 SCMG-2000: Trailing right behind the two leaders is the $35 Mugen-II cooler, which already includes AMD mounting hardware and a premium Scythe Kaze-Jyuni Slip-Stream fan... all for only half the cost of the the other two options. The SCMG-2000 model has already received honorable mention for our Editors Choice Award pertaining to value, and it consistently finishes at the very top.
EDITOR'S NOTE: The Scythe Mugen-2 Revision B model SCMG-2100 heatsink is identical to the first version, model SCMG-2000. The only difference is that Mugen-2 Rev. B uses a newly developed F.M.S.B. (Flip Mount Super Back-Plate) for more convenient mounting onto the motherboard. There should not be any cooling performance between these two models, despite marketing hype.
I have had my Mugen 2 Rev B for about 2 weeks now. I am @ 3.9 on my i5 750. Idle @ about 39-41C and load around 62C with ambient temps 28C. I also have a Coolermaster HAF 922 case with 3x200mm fans. I had no problems with plugging in the fan to my P55 LE mb. The Scythe fan it came with is by far the quietest fan in my system.
