Introduction
Traditional computer fans are made to expel air, so for years, airflow was the most important rating that determines cooling efficiency as most fans are used as exhausts. SilverStone created Air Penetrator fan specifically designed for intake fan applications, where airflow rating is not a priority. The design goal for Air Penetrator is to focus airflow into a column that can be channeled through various obstacles inside the modern computer case for more efficient cooling performance. Compared with traditional fans, where airflow spreads outward and further looses focus with resistance added (e.g. filters, fan guards, etc…), Air Penetrator fan’s unique blade and grille designs can create enough pressure to push air as far as 1 meter away with minimal fan speed and noise. This unmatched efficiency makes Air Penetrator ideal not only as intake case fan, but also perfect for high density heatsinks and radiators.

Special Feature
Industry leading air channeling fan.
Wide fan blades for reducing air resistance.
Standard 120mm frame for maximum compatibility with CPU coolers.
Integrated air channeling grille double as fan guard to reduce overall size.
Low power consumption.
The Fluid Dynamic Bearing (FDB) for high reliability.

Hm, looks pretty interesting! :up:
Wonder if the grille noticeably reduces airflow, though.

That video pretty much says it all. Pretty cool, wouldn't mind trying a few out and seeing if temps drop any.

good stuff, i wonder how it would do against the Scythe Gentle Typhoons, those are the best fans out now, push alot of air with low noise.

I wonder how these would do as Rad fans?

I'll admit the demo is pretty cool. I wonder if it actually works like they intended, to provide better channeling of air through a case? It was pretty clear the regular fans kind of shot air out in all directions.

anything blocking the fan lowers total flow or pressure. but it doesnt matter when the flow doesn't go where you want it to. thus airflow straighteners. these are not new. example: http://www.frostytech.com/articlevie...articleID=2323

Just like some delta fans.

So they ripped off Vornado huh?

I know this design DOES push air forward, I just wonder how the noise will be. I think this'll help rads, especially ones w/o shrouds.

yeah, vornado copy heh :D
who cares, if it works...

but i dont see how this is a new fan, the only new thing i see is a fanshroud/grid added to the fan.
so shouldnt this work with any fan?
these would be great as casefans, but for heatsinks... idk... im not sure how much of a difference a slight correction in air push direction makes there...

oh and errrr penetrator? really? :p:
marketing fail... ^^

lol, not so fail. I'd buy one just because it says penetrator... is that wrong?

"hello ? yes, I'd like to order some 120mm penetrators" :p:

Notice how the grill is curved in the opposite direction of the fan blades, that's what does the correcting. I assume you could modify any fan like this, given sufficient pressure.

this will make stacking fans in series actually beneficial now! Where's Martin...

Welcome to the party guys :party:, I guess you guys don't follow Silverstone too much, those fans have been out for months and are used in the Fortress FT02 WRI special edition case, very nice case by the way, pickup one awhile back for my new build.

for any FT02 owners, the new SST-AP181 push more air without any extra noise.

I read somewhere that stacking fans in series only works if the fans are counter rotating, like that 120x76mm Delta GFB1212VHW.

"C Company" I can see the CM logo :ROTF:

mmm, I guess you miss read the OP"s post, he was talking about the new SST-AP121's and he missed the part that there are also the new SST-AP181's out.

The Raven 02 does not use the new SST-AP181's, is uses the regular 180mm fans http://www.silverstonetek.com/produc...no=FN181&area=
( I own a Raven 02 by the way.)

maybe higher static pressure due to basically directing air like a convergent lense. But I doubt they'd be better CFM overall, or better noise. Difficult to say how much it will improve air flow through a heatsink: Airflow on the normal fans tend to diverge after it exits the fan, like case fan scenario. But if the fan is already right next to the heatsink, you might get very similar static pressure anyway...

If the heatsink is designed to take advantage of the way the fan expels air, we could have a good combo here.

I haven't read that, but I heard it from my father before. Makes sense too if you think about the motion of the air. Two fans in the same direction = 1 fan pushing and a second fan chopping up the air. Two fans with opposite rotation = benefit.

this is best used for two fans with relatively high CFM and relatively low static pressure.

hope that silverstone will made 140mm version.

both wrong,those are 100mm fans not 120mm or 180mm and they've been used since the TJ07 which has been out for 4 years now:)
just kidding,i couldnt help myself,im addicted to one upping people:rofl:

even if it means making things up:ROTF:

i wonder if these will reduce the benefit of a shroud on radiators and therefore reduce some footprint

Silverstone has been making good fans for a good while, and this will hopefully carry the same tradition.

I've get a SilverStone FT01 newly, but it is getting old now. I got really surprised to see how quiet and effective fans it has. Those 2 x 180mm 700RPM pushes a lot of air without making any noise.

The SilverStone FT01 is really little, litle and quiet case, but it has much better cooling than my good old heavy and big CollerMaster 1000 with 5x120 fans.

Air Penetrator?

Nice Name....


For a blow-up doll.


Nah but looks cool, I would try it.

The directional vanes are pretty much what Delta's been using on their FFB series for some time now. Except that these can go slow enough that you can't hear them from fifty feet away.

Still, the overlapping fin design is interesting - I've often thought that that sort of thing could go a long way towards improving static pressure. Mind, the listed specs aren't too inspiring, so who knows.

They're called "stators" - critical in turbine design. In turbine design, some energy is lost on the stators but it's made up for in over all efficiency by optimizing the incident angle for the next turbine row. i.e. overall energy lost to the stator rows is less than what is lost spinning the air, or something like that.

This would be better for stacked fans, but not optimal unless designed for it. It would probably be more efficient than counter-rotating fans depending on individual fan deisgn. The major advantage that I see is that, with these, you're not just increasing pressure within the case, you actually get well directed airflow. I would expect static pressure, measured normal to the fan, to increase vs not having the stators/vains/fins, total pressure would probably decrease a little.


Edit:
MpG, 0.067 in-H2O spec'd max static, I think this is inline with YLs by noise - if the spec is true. Maybe slightly better. I'd like to see the P/Q curve.

exactly. Counter rotating fans means that the second fan will be able to "spin" /benefit. Since the grill de-spins the air, then the second fan will be able to help.

The FT01 is a great case, still have it but I move to the Raven 02 and now the FT02 special edition case. The new AP181 runs up to 1200rpm`s and they are just as quiet as the fans that the FT01 use when ran at 700RPM but they seem to push more air at the same RPM :up:

Same here hahaha I see "C Company" and I'm like "WTF?" and I look and see this:

The cheapest fans. the R4s....

Definitely not for silence fanatics (like me :) )...

It'd be interesting to see. On the other hand, Noctua's NF-P12 fans advertise 0.066 in-H2O at only 1300rpm. But yeah, in all cases, we have nothing but the manufacturer's specs to work with.

Doesn't Delta make fans with the same basic design principle?

< puts 10$ on next model being called 'Atmosphere Intruder'

Yep.

You know... someone should just make a plastic insert you can put under any fan that does this...

Actually, Silverstone will be making grills that allow this air tunneling effect with any fan. :)

Sweeeet. :yepp:

It's good to see companies trying new things to get better performance with less speed and noise. But unfortunately I don't see any company out there doing the kind of 'outside the box' thinking needed to truly revolutionize air cooling.

The last time I saw a company really "think different" was not Mac (couldn't help myself), but was YS Tech who made a series of fans without a motor at the center. Rather, the fans had magnetic tips and the actual motor was built into the outer frame itself.

IMO, it was a great idea. Unfortunately nobody picked up on the concept and further developed it.

http://www.dansdata.com/images/coolercomp/tmdfan250.jpg

TMD fans kind of sucked.. good idea, poor execution.

edit

What would be interesting is a TMD fan with forward-curved blades (tips ahead of center of the fan) and the blades dimpled like golf balls... with a vane under the fan like silverstone is supposed to be making soon apparently.

Not an invention. This iscalled stator vanes, every axial compressor has them, and fan is a simple axial compressor.

only 120mm? ^^

230 mm would be enough :p:

nice vid ! Is it dust?

read. :shakes:

so the real innovation is the new grill added right in front of the fan. otherwise, it's just a regular fan i think.
