Akasa AK-FN057 Apache Super Silent 120mm Fan - 4 Pin PWM

Akasa AK-FN057 Apache Super Silent 120mm Fan - 4 Pin PWM

Super silent 12cm fan with S-FLOW blades supplying 30% more airflow than a standard fan at the same speed. The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum. The Apache fan creates more focused airflow providing blind-spot cooling, which makes it an ideal solution for a case or heatsink fan. HDB (Hydro Dynamic) bearings extend fan life and further enhance noise reduction. IP54 military standard ensures the fan is dust and moisture resistant. It’s powerful, quiet and tough!

PWM is a widely available feature on all current Intel and AMD platform based motherboards. It is more accurate than voltage regulation, energy saving and a fully automatic way of controlling the fan speed. PWM provides ultra quiet acoustics during normal PC use and high performance cooling under high system load. The Optional Akasa AK-CB002 cable adapter can provide the system with two additional PWM connectors if needed.

I noticed you just got these in stock - any reviews or anyone able to confirm that they really do have the CFM to db ratio they claim? Might decide to replace the Akasa amber fans I have at the moment with some of these if they're good

That's a very impressive static air pressure figure for a 25mm fan. In fact it's about 60% of my San Ace 38mm fans although the quoted sound levels poos all over my San ACes.

If the manufacturer's claims are true, I cannot think of another fan which even comes close to the cfm/air pressure at that volume. In fact, you may as well just stock these and stop selling all the other fans.

Will be interesting to see reviews. They look very similar to some Scythe fans and unless there is magic going on, I seriously doubt those dB figures..............

If Im not mistaken they are better than the Noctua NF-P12 Vortex-Control.

BSmith · 10 Jul 2009 at 10:42

Are these type of fans good as CPU Cooler fans on a Megahalems?

satman · 10 Jul 2009 at 10:55

Wonder if they any good for a Water cooling system ..

Notice that it as 9 blades as well ...

Greebo · 10 Jul 2009 at 11:53

With that air pressure they are excellent choices for both cpu coolers and radiators.......if it's true.

The manufacturer's stats shows they are better..........

No reviews online anywhere yet?

Nah. Googled it this morning. Loads of people talking in forums about them and lots of sites selling them but no reviews yet.

kkbigal · 10 Jul 2009 at 12:56

Aye - Google turns up nothing other than lots of other people asking for reviews

If they match the advertised specs then I'd probably buy 2 of these for a push/pull on my Megahalems and replace the other fans in my case as well.

Diggsy · 10 Jul 2009 at 13:31

Looking at the specs these claim to have 26.4mm H20 air pressure, yet the similar speed and airflow Noctua NF-P12's have only 1.68mm H20.

And the Akasa Ambers are listed as having 1.1mm H20.

Something doesn't look right there. Surely that figure for the Apache fans can't be right? More than 15x as much pressure as the Noctua?

EDIT, and a bit of Googling suggests even the 1900RPM Scythe Slipstream fans only have 2.3mm. Surely Akasa have this wrong?

JonJ678 · 10 Jul 2009 at 13:54

26.4 mm h20 is just shy of 260 Pascals. I'm sceptical. Out by a factor of ten sounds plausible, but doesn't lead to confidence that the rest of the measurements are accurate.

It scales fairly quadratically with rpm as well, and this only goes up to 1300. I think there are lies hidden behind the word max

We shall see, I'm in no rush.

I would agree. I missed that. I suspect it will be 2.64mm which is still very, very good for a 1300rpm fan and 16dB

The man knows you know, bloody brain box lol

Well I for one would give them a go!!

Any eta when these will be in stock again ?
And if a 92mm version will come

Cheers

SH4RKY · 27 Jul 2009 at 14:03

Yup, any info on stock update?

There is a single review I've found but conclusion was based on opinion etc rather than comparative tests etc. although it was highly recommended.

If they even come close to the manufacturer specs ill be replacing all my case fans with these. Save some money over the noctuas I was going to buy too!

Anyone on here have some from the first batch of stock? Thoughts?

JonJ678 · 27 Jul 2009 at 14:36

Also want to know if these are living up to expectations, though the scythe gentle typhoons are probably the next to get my money

setter · 27 Jul 2009 at 18:26

Id also like to see a proper review of theese as well, wouldnt mind tryng a pair on my TRUE, currently have 2 sharkoon silent eagle se's, 400-1200 rpm pwm fans, quite like using pwm fans due to the speed control.

bulldog147 · 27 Jul 2009 at 18:51

I had two of those but the temperature and noisey is the same as Noctua NF-P12 (no difference) even with these great airflow.
