Specifications, Availability and Pricing
As much as I hunted, the only specifications chart I could find at Scythe's website was in Japanese. So I had to go ahead and make a chart that was somewhat readable. On that chart you can see that the Mugen 4 also goes by the name SCMG-4000, and this new version measures up at 130mm tall, 88mm wide, and stands 160mm from the IHS to the top of the caps covering the heat pipes. The entire mass of the 50 fin stack, copper base components and the six 6mm diameter heat pipes weight in at 625 grams without the fan. The base of this cooler keeps the heat pipes spread evenly across the CPU, but after they leave either side of it, three pipes are bent gently to go into a section of the fins, while three pipes are bent tightly to go into another section of the fins. This is evenly done on both sides and leaves you with four fin section containing three pipes each to spread out the heat load and allow it to dissipate more evenly into the aluminum fins so that the fan can easily remove it.
Speaking of the fan, you are sent the SY125HB125M-P, a 120mm by 25mm fan to strap onto the cooler with wire fan clips. With minimal voltage supplied, this fan will spin near 400 RPM, with a 5.3dBA sound rating, 0.12mmH2O of static pressure and 20.7CFM of air flow. Let me just say it is little more than a gentle breeze at idle. Pumping up the voltage to 12V will give you 1400RPM, 28dBA of noise, close to 80CFM of air flow and 1.56mmH2O of static pressure. With the fan added to the cooler, it will make the cooler now 113mm from left to right, and weighs in at just below one kilogram. As far as the socket compatibility goes, Scythe allows anything from 775 to 2011 on the Intel side, while on the AMD side, you can use this on anything AM2 or newer.
From what I can gather, since the end of April, the Mugen 4 is available overseas, more specifically in the Japanese market. As I look around I have yet to find a listing in either the US or EU markets, but the pricing was set with the news of its release in early April. It was then we were all told that the Mugen 4 would release at 4,980 Yen or roughly $50 US dollars.
It seems rather rare these days that anyone is offering air coolers with a price tag of near $50, and it is refreshing to see that Scythe didn't take this cooler to a higher level of pricing, and stays where they are comfortable, delivering a lot of cooler for a good price; something we can all appreciate.
