Scythe Readies Fuma Dual-Stack CPU Cooler

Scythe is close to launching its latest high performance CPU cooler, the Fuma (SCFM-1000). This aluminium dual-stack (D-type) heatsink features two fin-stacks with a slanted fin pattern that maximizes heat dissipation by exposing more metal to the air-flow. Heat to the two fin stacks is led by six 6 mm thick nickel-plated copper heat pipes. These pipes pass through a nickel-plated copper base with mirror finish. A pair of 120 mm PWM fans come included, the heatsink itself supports up to three fans - intake, conveyor, and exhaust. The included fans support 4-pin PWM input, and spin between 300 and 1,400 RPM, pushing up to 79 CFM of air, each, with up to 28 dBA noise output, each. Measuring 137 mm x 130 mm x 149 mm, the cooler weighs about 920 g (including fans). All modern CPU socket types are supported, including LGA115x, LGA2011v3, LGA1366, LGA775, AM3+, and FM2+. The cooler is expected to launch later this month, beginning with Scythe's home market of Japan, on the 21st.

Looks good,....

Wonder how much it will be stateside,...?

Do dual fans/smaller heat sinks actually work better than larger heat sinks with only one fan? You'd think it would be a function of surface area more than air flow.

I thought the same way too. The scythe ninja 4 the large single tower cooler do perform about on par with dual tower design with just one fan which is quite amazing, I was reading the silent Pc review on it.

If they perform similarly, the single fan model is likely superior simply because it won't use as much power.

There aren't any dimpled heatsinks out there is there? Dimples improve airflow.

I think its both surface area and airflow which is important. Basically you have to maximize both as must as possible in order to get best performance.
As the fins do restrict somehow airflow, as the air has the tendency to stick to the surface (coanda efect I think), it is possible that actually 2 fans provide better airflow and better air spread across the surface of the heat sink.

Its for sure a good cooler, but nowadays in a world with most popular desktop CPU in the 65-95 W range, it looks like an overkill for most of the people, except for enthusiasts/overclockers obviously.

looks suspiciously like 2x Evo 212's merged into 1 unit.........with the possibility to add a 3rd fan :)

Definitely overkill for everyone except o/c'ers and the "built it cause I can" crowd....

The gelid tranquillo rev 2 has dimples, if I know what you are talking about. I find it odd that gelid doesn't make cpu coolers with dimples anymore.

It's dimpled (they only show the dimples on the top of the heat sink):

I found another one too:
3Rsystem's Iceage 120 Boss II

Both models, the dimples aren't what I expected (they're tiny). They still preform better than no dimples though.

Dammit, why didn't I think to look for that before buying my Scythe? :(
I don't understand why dimples like that are not more popular. Even gelid stopped using them.

Production costs, likely. It probably raises the cost 20-35% which, from the passer by, just looks like it's more expensive for no reason. I think if there was a marketing campaign for dimples, they could come and they would stay. Without public awareness though, it can't sell itself.
