Just spotted this:
http://www.guru3d.com/news-story/scythe ... -fans.html

Not much other info on the web yet that I can find. It's more evolution than revolution really. 2 fans, a black finish, new mounting hardware and some cutaway fins at the bottom of the stack to allow the use of infantile tall RAM heatspreaders.

I am a bit cautious about it for a few reasons. Scythe fans haven't been that great for a while so is it really an advantage to get 2? To me that would just be 2 fans to add to my stash of spares. The black finish is more marketing than anything else, mounting hardware I'm sure will help for some compatibility.

The one thing I really don't like though is the smaller fins for more RAM clearance. If you are buying a Ninja you probably don't have 55mm tall RAM and if you do, first get your head checked and if you are still convinced that you need to overcompensate in such a way for your other shortcomings, take a pair of tin snips to the lower fins anyway.

Also, the shape has changed - it no longer has 4 identical sides, it is clearly intended to be used in one orientation only.

In summary I don't like it on first observations as much as the Ninja 4 but maybe benchmarks can prove me wrong.

Yes that's an interesting development. I must say the Mugen 5 Rev. B looks to be a lot easier to fit on most motherboards, and I am not sure that it's performance is that far behind the Ninja 4 or 5

Thanks for the link, I note that the results on an Intel 201x platform at maximum stress are not so good, to me it looks like the 800 rpm fans are just not fast enough. I think it would have been better to have provided 2 of the standard 300 to 1200 fans rather than the 300 to 800 fans.

Correct. Compared to the fans provided with the other coolers the Noctua fans aren't loud enough...
In the other tests all coolers are compared at the same (measured) noise level, and there the Ninja do just fine!

The main issue for me with Scythe CPU coolers (and incidentally I own two of them) is the almost complete absence of information on motherboard compatibility. This is the one factor that I think will hold back Ninja 5 sales. It is a very big cooler depth wise and I suspect many potential buyers will pass it by simply because it looks to them that it won't fit.

Thanks, Barto. Nice review. While the acoustic setup is limited to ~31dBA, but there's still a bit more information that can be squeezed out. I'd love to see the addition of a test showing min starting rpm vs temperature...maybe in the upcoming passive article.
