One 15 mm fan, not really expected. Running in opposite directions?

Yeah, I'm sure they're doing it right, it's just that I don't know if I've seen fans running in the other direction before on a heatsink.

It looks fairly beefy for a $60 cooler. Kudos to Scythe

That's because the propellers are right next to each other, creating extreme turbulence when the rearmost propeller cuts through the airflow path from the front one. This won't be an issue on a heatsink when there's a thick aluminium fin stack in between the two.

That's interesting, I wonder if it's doing vortices with the reverse fan. It looks like it's trying to twist the air, allowing the air to be more attached to the surface of the radiator longer (stupid wild guess).

Also because the propeller tips are moving at supersonic speeds wich is obviously not the case with these fans !

Hopefully, they did their (eginering) homework on these & didn't just slap something together so they could say "look at us, we came out with something really cool & innovative"

Because to me it just looks like 2 Hyper 212 clone-joners back to back, hahaha :slap:

I think there is a massive difference twixt a small contra fan setup and a contra airplane setup. Cooler looks good though, price aint bad either

This cooler is already available in Japan and here is the review article tested with Core-i9 9900K.
http://www.gdm.or.jp/review/2019/0501/300092

With CPU temp of 9900K running stock with room temp at 20.4C, it was 33C at idle and 85C at heavy load.
123087


And with fan noise, it was 34.8dBA at idle and 38.6dBA at heavy load so this cooler isn't that noisy as some of you are concerned.
123091


They've also ran the test with 9900K OC'd to 5Ghz on all 8 cores and the following are the results.
123092

123093


As you can see, the temp is under 90C and the noise is under 40dBA even running at heavy load so this cooler is quite a beast IMO.

Those test figures don't look that good to me, also:
Air Flow: 8.28~33.86 CFM (Fan1), 16.6~51.17 CFM (Fan2) means that Fan 1 is basically ineffectual and Fan 2 is sucking air through the first tower then blowing it through tower 2.
To be effective it needs twin 25mm fans with the same air flow (cfm).

That probably has an effect, yeah :p I can't imagine a propeller hitting a turbulent airflow of that velocity at a 90-degree or higher angle to be a quiet affair. Quite the opposite.
Won't the differing airflows affect performance?
Why would they? Airflow is still in the same direction through the fin stack, after all. All this will do is break up the airflow, which can be beneficial both for flow and noise.
Those test figures don't look that good to me, also:
Air Flow: 8.28~33.86 CFM (Fan1), 16.6~51.17 CFM (Fan2) means that Fan 1 is basically ineffectual and Fan 2 is sucking air through the first tower then blowing it through tower 2.
To be effective it needs twin 25mm fans with the same air flow (cfm).
Not quite true: first off, those numbers are unobstructed, and with a design like this fan 2 is clearly obstructed more than fan 1, so it makes sense for it to be more powerful. Fan 2 even helps fan 1 overcome said resistance, while fan 2 only gets the same "help" in front, and not behind, which again makes it sensible for it to be more powerful. Second, the fin stack isn't crimped on the sides, meaning a strong middle fan will ensure that air doesn't escape out the sides but rather passes through the entire fin stack - improving thermals. Removing fan 1 would not have as large an effect as removing fan 2, obviously, but it will undoubtedly contribute to overcoming resistance in the fin stack and provide a more orderly airflow path.

@John Naylor might like this, always recommending the Fuma to everybody...

So your position is that we should recommending products that cost more, make more noise and perform worse ? If you can show us something that performs better , makes less noise and costs less and I'll recommend that instead. For me, it's always gonna be about the numbers.

As to the lead post, I notice that no dimension is shown on the product page giving the dimension to the bottom of the heat sink. On their product page they show how it works with the ridiculously tall heat sinks that have no value or purpose, but what about sensible selections ? The image in the post above leaves it unclear if it would clear or why if that heat sink cut out is necessary.

When TPU does the review, I hope they include the original Fuma Rev B for comparison

Because to me it just looks like 2 Hyper 212 clone-joners back to back, hahaha :slap:

The last Fuma topped the Hyper 212 by 11-12C in TPUs testing and the 212 was 23% louder. Interesting design ... the numbers will tell if it pans out

I think you read my comment wrong. I was simply calling your attention to the thread because I know you like the Fuma, so I thought you'd be interested in the Fuma 2. :)

Benchmark Scores bench...mark? i do leave mark on bench sometime, to remember which one is the most comfortable. :o
this with 2x nf-a25 fans would be pretty damn good for the space used

why would you mess up the price and swap 2 perfectly capable fans bundled with the Heatsink for 2 fans from an overpriced brand ...

but how good compared to the u12A?
you can bet it can be only good ... at 40$ less :laugh: even +5° non OC and -5° OC differences would make the Scythe a better deal (although can't take number from 2 reviews ... after all the -5° difference on OC was on a 4.8 8700K for the u12A and the Fuma 2 had a 9900K at 5.0 to cool down instead, same for the +5° ... 8700K 9900K ... who's the hotest :ohwell: )

So your position is that we should recommending products that cost more, make more noise and perform worse ?
i do agree strongly with you and also if it cost more and perform only slightly better : not worth it either.

If you can show us something that performs better , makes less noise and costs less and I'll recommend that instead.
and that's what most brand are to Noctua they all cost less perform on par or slightly under/over and noise is same +/-

With CPU temp of 9900K running stock with room temp at 20.4C, it was 33C at idle and 85C at heavy load.
View attachment 123087

it's written 73° ... just in case ;)

but reading that review ... it seems more than decent for the price (and it's not a 120 for nearly 100$/€ )

I don't know what your hearing is like, but that statement is pure nonsense. Yes, Noctua is expensive - nobody is denying that - but nobody comes even remotely close for noise normalised performance. Period. That's what the premium is paid for - not balls-to-the-wall performance, and not absolute silence, but the best combination of both. Sure, there are more powerful fans, like EK's Vardar, Sunon/Corsair MagLev or the fast version of the Gentle Typhoon - but they are also very noticeably noisier. Reviews show this quite clearly, but also miss the crucial fact of the audio profile, which is where Noctua always wins out for me - even when they're tied in terms of dBA, Noctua's fans generally sound more pleasant than the competition due to the sound frequency and patterns. There are also quieter fans, but none that match Noctua (at least not the NF-A12x25) in terms of performance. Usually the quiet competitors are slower, lower pressure, and perform worse on heatsinks and radiators alike.

Am I saying Noctua fans are always worth it? Of course not. If you're on a tight budget, spending $100 or more on a handful of fans is silly. But if you can afford it and want the best low-noise performance available, they can't be beat.

Benchmark Scores bench...mark? i do leave mark on bench sometime, to remember which one is the most comfortable. :o

indeed the 40$ premium over it make it worth it, i do agree ... (well that's a 120 versus a 140 although i would take a TR Macho 120 SBM over the u12A any time ... )

the only 2 sensible pros in favor of Noctua would be 1. warranty 2. customer service, although, that would be ... if i ever need any of those 2 ... i can recall one time with Thermalright and even out of warranty they replaced the piece and even gave me an extra set at the time (2 TY-147 and fixation + holding bracket) ... so, i am not 100% sure
