Silverstone "Penetrator" Fan Demonstration

[0roo0roo]

i'm just not sure ti makes a difference as a case fan. i know in other machines sometimes vanes like that are used to smooth air flow before the air hits another element, but i don't think it would do much on the way out of a case other than to make air flow cosmetically interesting. but yes..maybe on a heatsink who knows.

 

[aigomorla]

this kind of design is more optimized in a U2 factor case where u have tiny tiny clearance room and you need a more stream line air path.

Otherwise on a sink, im guessing its not worth the premium in price.

You'd get better performance with 2 yates which still run cheaper in a push/pull config on your sink.

I have a Mechatronics fan/vane device that gives the best temps on my heatsinks. It's also rated at 174 cfm . . .

I think I also saw mention that these fans are the first computer fans with overlapping blades. That should increase static pressure and help overcome the resistance the vanes cause.

LOL I bet that sounds nice.

That thing screams. Spec is 58 dBA.

Ok probably not as loud as this.

what resistance are u talking about when you have a stream line path?

blade fins on sinks are not staggered... there straight...
this fan would reduce turbulence and increase CFM though the sink, however u want turbulence on the fins.

As i said... were not putting our fans 1 feet away from the sink... its right smack up front against it.

I am talking about the resistance caused by the stator vanes. You put a zillion of them in the airpath, and you will get resistance.

I am not talking about staggered anything. I believe I saw a photo of the sign in front of that fan at a recent expo. It said it was the first computer fan to have overlapping fan blades. If you look at all of the fans we haveyou will see that none of their blades overlap. I have more than 70 fans, and none of them have overlapping fan blades. If these fans do, then they will have superior static pressure.

I miss read your statement...

I could of sworn there was a fan which did overlap its blades.

It looked like a jet turbine and it also sounded like one.

and by overlapping the blades dont you lose CFM?

And yes i know you know your fans... im the one who stickied your thread.

I can't tell you if you lose cfm or not. I'm not advocating for the fan, just reporting what I saw. It certainly wouldn't be the first fan to trade cfm for static pressure. The GT's do that.

And these fan blades don't quite overlap.

yeah i heard if it did overlap, you would lose out on a lot of CFM.

:\

If anything i think they should try to reduce the dead spot foot print in the center of the fan more then shape the air of the fan.

Tribewerks did it, but at 30 dollars per fan... its serious ouch.

 

[DrMrLordX]

my friend iandh was starting a project onn it until we realized we wanted turbulance in fronnt of the fan.

its the turbulance that increases heat transfer.

so straightenig ur air flow and minimizing turbulannce is only good when ur in a winnd tunnel.

remember ur fan is right smack front of the sink fins... not 1 feet away from it.

Interesting point.

The Honeywell desk fan I use has a stator vane on it, making it really easy to direct airflow into the open side of the case and hit whatever I want, but since it's blowing straight in from the side, the airflow runs smack into various heatsinks/RAM heatspreaders/etc. instead of sliding past things.

 

[aigomorla]

Interesting point.

We should be moving in this direction.. but not have it cost 30 dollars per fan.

[Rubycon]

If you really want maximum efficiency you need a duct. All of our pro audio equipment is cooled this way and never do you see a fan anywhere near a heatsink.

 

[jaqie]

That's a very interesting setup, but it's not a new idea... the first time I saw it was on those delta black label screamers, and even the little 40mm fan in a 1u 250w sparkle ltd psu I have here has (a different design) of what I call inverse static blades on it...

Personally silence and actual running life reign supreme to me, which is why I buy the Scythe S-Flex SFDB fans whenever I can... 150,000 hour MTBF and I've got some well past that that still look completely new after a gentle cleaning.

Hmm. Correct me if I'm wrong, but 150,000 hours is a little more than 17 years, and Scythe has not been in business that long. Wasn't 17 years ago when Win 3.1 came out?

 

[jaqie]

>.> I musta miscalculated... LOL

(sorry... I've actually got dementia... messing about with my memories... not fun)

I got it 7 years ago and had been running it 24/7/364 or so.

 

[ehume]

61,320 hours. That's a l-o-o-o-n-g time in fan years. Hmm. 3,679,200 minutes. Let's say 1600 rpm. 5,886,720,000 revolutions. Quite the fan.

ys tech tmd
not much came of it, going for surface area alone is not the win apparently.

 

[Rubycon]

TMDs are horribly noisy. They sound hilarious when starting. That's the kind of noise that gets old after two minutes. It's like watching a hockey game after the first fight...

 

[0roo0roo]

heh yea seems its discontinued...
didn't look too hard through their site
stumbled on some of their other fans though

Here is a break down of the level of protection for each:

1. IP43: varnish coating, moisture proof
2. IP44: conformal coating, splash proof
3. IP55: Paralyene coating, submergible
4. IP67: Encapsulated motor with complete protection.

The coils seem pretty far from the rotor, does this motor even work well?

How does this motor work exactly anyway, is it a permanent magnet motor?

Interesting idea.

 

[Rubycon]

Yes it works and yes there are permanent magnets in the outside ring. All commutator-less fans use permanent magnets.

the magnets or whatever are in the rim as said. theoretically it would be even nicer if the bearings were in the rim, you wouldn't need a center spindle at all.
i 'm guessing it would cost too much though
