Silverstone’s “Air Penetrator” fan not as kinky as it sounds

Silverstone’s “Air Penetrator” fan not as kinky as it sounds

Despite a name that will cause us all to chortle, Silverstone's new fan airflow is so focused it can keep a balloon suspended in mid-air.

We popped into Silverstone’s office here in Taipei for a quick look at its new products and, among other things, were presented with its latest fan, the “Air Penetrator.”.

Now, we’ll give you a minute to stop sniggering at "Penetrator" and then we’ll carry on.

Ahem, feel better?

The new fan, which has the model number AP121, will come in 120mm and 180mm varieties – the latter for its Raven, Fortress and future cases – and Silverstone claims it’s the largest single moulded fan with overlapping blades. The blade size is about 50 per cent larger than normal fans and combined with the opposite angled grill on the exhaust side that acts to direct the airflow in a very linear angle from the fan.

It’s not the first time opposite an angled grill has been used, but Silverstone claims its fan is the first to use a close-pitch approach with many more twists.

The Air Penetrators are due for release soon and SilverStone is estimating the 120mm will retail for about $15. Interested in this new fan? Let us know in the forums.

Surely one would need number before being interested in a fan? But for now, it certainly sounds promising. ;)

interested. it looks cool. and it gives you street cred too! "yeah baby, my hardware is made to penetrate in a straight line. it'll keep your balloons floating... and with all the twists and my close-pitch aproach, you'll be blown away"

Someone needs to employ in marketing, that;s genius :D

Hmm I might get two of these for my RV01. I beed something to improve the airflow!

This would do well for... what?

Radiators don't really need linear airflow - the casing of the rad tunnels the airflow already. Case fans also don't really need linear airflow. They just need to get air in, and get air out.

Seriously, I don't particularly see the point...?

So are you saying you will have double penetration? 4 mintues and you stole it from me

I agree with rickysio, when you want something to be air cooled turbulence is your friend so why would i want a linear (i dont think its good enough to say laminate) flow fan? The only time I can think of that being useful is if whatever you are cooling, the back of a GPU PCB for example, is at a right angle to the fan.

My thoughts exactly. I really want to think of a use for these, but other than having one in the roof and floating a balloon on top I can't come up with anything.

Only spec I can see is 0.33A which means they'll be loudish but the design should make them good for radiators and tower cooler, especially in push-pull. I'm trying to persuade them that make decisions to do triple pentration kits.

If we're talking about case airflow - laminar is better (moves more air in given time period). If we're about heatsink airflow, then it's the other way around.

:) love the name.

i think use of this is in cases that you want to direct where the air end up. with normal fans, the air spreads out too much. with these, you will be able to place one further away from the graphics card intake, trusting its directed wind to work its way into the graphics card.

As there's normally a fan at the front and one at the rear.. Will there be a spitroast edition?

Too far?
rickysio 22nd April 2010, 15:09 Quote
So I've spent some time thinking about it, and honestly? Floating 3 balloons above your radiator should be a pretty cool party trick.

Jokes aside, pretty much I think the only use is to direct focused air across passively cooled cards.

But if you go for passive cards, you go for silence, not this type of 0.33A loud-ish fans.

Besides, all one needs is a 120MM diameter tube, and any normal fan pumps out nearly laminar airflow!

I used to have a 60mm delta fan with a similar angled grill on the other side (which made the entire fan almost a cube), and while it was pretty direct flow, that might have been due to the stupid rmps that that fan put out, truly a screamer.
It eventually met its end when I managed to get a finger too close. Damn thing cut right to the bone before the blade snapped.

Looks **** for cooling. Why the hundreds of struts that block airflow, create turbulance (expect this fan to be hella noisy). It may look geeky and cool but itll perform ****. You cant get around science, no matter how good your marketing is.
Sparrowhawk 22nd April 2010, 17:39 Quote
Are they only going to sell the 120mm fan stand-alone, or the 180 too?

Consider Silverstone. An excellent developer and manufacturer. I very seriously doubt that they would waste their time, money and reputation to develop something that we consumers would find lacking and fail to purchase.
You people obviously don't have your heads up your own arses or you'd realize that fans also have 2 sides. They have intakes AND exhausts. Isn't a linear exhaust a requirement for a high-performance engine?
When an object apparently doesn't make sense head-on, turn it around and think at it from the back.

As mentioned, airflow to noise^2 ratio is what interests me.

Is it just me or are 140mm fans completely ignored? I'd kill for some nice ones to go in my case!

Whoever said that the difference in design (i.e. the narrow band of air flow) wouldn't make these fans directly incomparable on statistics alone?

Think of the range and power you gain from a directional yagi aerial over say, a dipole. There are trade-offs in either case, of course. But there is a huge difference from narrowing the area in which the energy is directed.

But it might not lead to anything. We need real-world benchmarks, not figures.

That should teach that fan not to mess with your finger !

Really? So every product ever released onto the market is brilliant right? There's no one product out there (even from Silverstone) that when applied to an application in the real world fails miserably or doesnt match up to its expectations?

Consider Palm. Explain to me why they are going to kick the bucket soonish?

When your (initial) argument makes sense, turn it around and think at it from the other way, before posting it.



HP attached a honest to goodness 5400RPM fan to my Q6600's stock heatsink (which is basically a piece of crap extruded aluminium piece) and on full speed it buzzed like heck, while I awaited liftoff.

Come on, don't act like you don't get their point.

They didn't say Silverstone are immune to making bad products, but if you look at it sensibly, it's unlikely that they'd bring something all the way to the market that they knew was bad. They're a business, they're there to make money.

It's this point exactly. Sometimes it's not until you develop a product that you might find it just isn't needed or the design creates more issues than it solves. We'll see when we do another labs test I suppose.
Picarro 23rd April 2010, 14:24 Quote
for the Raven RV01 you actually don't want any turbulence. The main point of the 180mm fans is to push the air from the buttom, and out of the top. A "direct" airflow would be better for this than a turbulent one ;)

When laminar airflow hits hardware components, its laminar no more.

A turbulent airflow remains turbulent, laminar becomes turbulent. Besides,
Quote:
When the flow is turbulent, particles exhibit additional transverse motion which enhances the rate of energy and momentum exchange between them thus increasing the heat transfer and the friction coefficient.

So turbulent flow is actually better for whatever (cooling) purpose we have, since laminar airflow is less efficient at heat transfer...? Someone call the SS engineer who proposed this. :X

maybe ..having overlaping blades will increase the static pressure and work well when attached to a radiator too

Exactly, they can still make money off a bad product. Just look at the iPad, it's a bad product but it will sell.

That's actually a can of worms you shouldn't open. There are hordes and legions of Apple fans who, capable of thinking, will take appropriate and reasonable offense at your statement.

Then again, Lian Li did release that WTF of a case.

I can't believe all the negative comments.

My machine would benefit greatly from have one of these at the front to push air past my passively cooled graphics card, and out the back.

I'd like to see whether the effect works well at slower speeds.
