(Pic Showing 10,546rpm)

Some interesting facts:

A normal MCX159 has 96 pins, The Mcx159Mrb has 163 pins!
A normal MCX159 is 40.4 x 40.4 x 42 mm, The MCX159MrB is 50mm x 50mm x 38mm (these numbers are without a fan)
The Normal Swiftech Fan rotates at 5200rpm, The MXC159MrB Fan with COUNTER-ROTATING fan spins at a mind boggling 10,500rpm
THE MCX159 produces 6.3cfm, The MCX159MrB puts out 18 or 22cfm
The MCX159 produces 18dBA, The MCX159MrB JMC fan puts out 41.5-52dBA at 12volts......OK Swiftech wins in the quiet department :)
The Swiftech MCX159 costs around $30, The SwiftechMcx 159MrB for just the heatsink alone (MCX4000) is double that, so we win right? :)


For Performance numbers you'll have to wait for the Front page article, probably sometime next week.

PS we will run tests using this incredible counter-rotating blade fan running from the crazy 12volt 10,500rpm, down to 4 or 5 volts for those of you like myself that don't like high noise levels.

I'll say this though, if you liked the 60mm Delta Black Max back in the day, you will love this fan even more if your crazy enough to run it at 12volts, when this review is done I will be running it at probably 5 volts. :rolleyes:

What's the advantage of 2 blades going diff. directions at the same time? I don't see it.Please explain. Thanks,THE FANMAN:cool:

[stan03]

i think there is more pressure which is a good thing.

how loud was the fan?

[archilochus]

41.5-52.0 dBA.

All axial fans produce a conical, spiraling airflow in open air. Some fans have static outlet fins to tame this phenomina(sp?); making the flow more cylindrical and straight. A counter-rotating fan takes advantage of that spiraling inertia (wasted energy from the first fan). A properly designed counter rotating blade will look quite different (not just reversed) from the primary fan's blade. The end result is a much higher static pressure, and increased volume.

Thanks for explaining that, I'll also add this fan has 5 blades on the top and three on the bottom, the top blades are skinnier than the three fatter blades on the bottom, I would assume they produce equal airflow, but this fan blade configuration produces interesting airflow.

I am going to do some Googling today and see if there's any way I can take pics of the actual airflow pattern using Mcgyver like methods ;) (I am leaning towards going to a fireworks store and buying some Smoke bombs, Gotta love fireworks being legal in FL. :)

I have to borrow my best friends Digital camcorder if I figure out a good method to capture the airflow on digital media, then I'll make a short 20 second movie, with my luck the fireworks store will sell me a mislabeled smoke bomb, and selling me a M80 instead, thus blowing this fan up :p

Heck yea McGyver ROCK!

[L337 M33P]

Or, you could go into a really cold room, then have the fan suck warm air out of something like a hairdryer blowing into a large box - illuminate past the fan and you should see the refractory effects of the two different air densities producing a kind of swirly image.

I have a 20Lbs Co2 tank for the bar I used to have at my old Abode, perhaps I can figure out a way to do something along the lines that you suggested. Thx

[rugbyroy]

I have a question. What if you took two of the same exact fan, and hooked them together somehow, but running in opposite directions. Would that have the same effect? Or is this fan special somehow

[Twigs]

I think the fan is special...

The problem is that if you did that, is that the fans would cancel themselves out if they were running in opposite diections, Even stacking fans of the same type blowing in the same direction is problomatic.

The Sweet deal with these fans is they counter rotate to produce the best possible airflow.

[wildfrogman]

Cool sneak peek, maybe these fans will become really popular and playing around~testing the really new stuff is always cool.

They are making them availablefor sale soon through vendors I have recommended to them.

[trinketsummoner]

Is there anything to be gained from having 2 fans on the sides of the heatsink - one pushing and the other pulling the air?

*Is a fan newbie*

[Minjin]

Good idea. I liked it so much that I just bid on and won a MCX370 off of ebay that I'm going to try the same thing with...although I have no desire to run a 52db fan with it. :)

It looks like it will be nearly identical to a 4000 after its cut down.

I think I saw a picture of a helicopter that used this same principle.

Great link BillA... thx for that ^_^.

me too, it didn't need a tail rotor because the blads on top cancelled out the urge for the helicopter to spin


now only if sss could do what billa found

[ShaDrag]

W00t can't wait for the review, everytime I see this, I just want to turn my Alpha PAL8045 into a chipset cooler!

[ShaDrag]

BTW the helicopter thing doesn't really apply to fans... the helis are dealing more with the rotational inertia of the blades, not spiral airflow, because they aren't fan blades, they wing shaped to create lift not to produce airflow. The same principle can't be applied to fans because we want to straighten the airfow, not the fan housing.

And to think the whole time Gabe and Billa were contracting a Hit man to take me out for defacing one of their works of art. :p

I am still going to wear my level III bulletproof vest 24/7 as this most excellent, informative post by Billa is probably just to make me drop my guard. :D


OK Bill and Gabe, I can't handle the pressure of being your competitor. I'll sell you the rights to use the design of the MCX159MrB for $.17 cents and a case of Hormel Luncheon meats, to be split 50-50 with Mr.B and myself.

cut the spam

we want DATA
perhaps an audio file as well ?

[9mmCensor]

thats a Silver pin heatsink I presume?

aluminum.......

There will be audio and a video as well, as I borrowed a digital camcorder. I have already stated Swiftech will win in the dBA dept. ;) But thank G-d this fan will operate at 4 volts. :)

*Patented Helicoid pin design (U.S. patent 6,469,898): pins are individually machined in an helicoid shape, to increase their surface area, and further enhance heat dissipation efficiency.


sam's rebuttal: The massive counter-rotating blades enhance the heat dissipation effeciancy to levels never seen before.

[SniperXX]

Man this nb cool looks soo cool. Cant wait til you guys are done with testing and we are all able to get the fans! :D :cool:

[vudoodoodoo]

Awsome.

[YellowDart]

Very kewl idea! Much more efficient to control airflow too...

<-- is imagining having 80mm versions of those counter rotational fans as intakes.... :D

There is a dual rotor helicopter that uses the same principal... I think the army uses one. I can't remember what it's called though...

Delta makes a 80mm and a 92mm counter-rotating fan, but they are next to impossible to get.

[stan03]

wow, they do, how much are they.... is it possible to get them? i want one on my heatsink

[wildfrogman]

I beleive you could get ahold of them.....but you would have to get ahold of a company that has a business account with delta that buys a few hundred or even thousands at a time. Your best bet is to know people that already bought some and would sell them to you, but prepare to pay a hefty amount.

[Robrules18]

im going to look into getting some of those man think if a 50 is 52 dBa think what 4 or 5 80mm's would be like....

[Mr. $T$]

De-facement of such a work of art is punishable by stoning.


However in your case we must reward by giving best NB Heatsink metal. :p but......


It still doen't save you from the stoning you will receive.

[stan03]

its not defacing, its just trimming off some excess fat :D

[JKeefe]

Warning, OT:
The helicopter with the two conter-rotating blades is the Ka-50 Werewolf, a Soviet design. As has been stated, this it to counter the effects of rotational inertia and has nothing to do with spiral airflow.

This looks like it will be an awesome front-page article. Runs at 4V, huh? That's pretty low.

The Army,Navy and Marines also use them, they are the Boeing Vertol CH-47 Chinook. Pictured is an E model

http://www.fas.org/man/dod-101/sys/ac/mh47e-2.jpg

And the CH-46

http://navysite.de/planes/ch_46_1.jpg

While I've flown on both the Ch-47 and Ch46's, I wish I had been able to go up in a Werewolf, but I've never even seen one in the flesh. (Been on a Russian Hind (http://www.af.mil/photos/Jun2000/000618-f-3050v-004.gif) in flight, but can't say I enjoyed the experience)

http://www.aeronautics.ru/kamov/ka5001.jpg

[JKeefe]

Ah, true, but the Ch-46 and-47 use offset blades. The Ka-50's blades are on top of each other. It's pretty cool, and results in a very maneuverable aircraft.
http://www.aeronautics.ru/archive/vvs/helicopters/ka-50-2-01.jpgTh Ka-50 looks a lot more like this fan assembly does. :)
Sorry, I'm a flight sim guy...

Don't forget the Canadian Sea King...

LOL Those crazy Canadians, I think they are fooling us, as that looks like a mini Submarine to me. :D :p

[eobard]

That's what's left of one of our Sea Kings. They're all in similar shape, btw that one wasn't shot down or anything, it just tried to take off from the Destroyer it was on. I wonder if Dubya knows that Marine One is a Sea King.

http://www.bearcraft-online.com/museum/photos/b.78.6.jpg

Can't forget the Tu-95 Bear Bomber either, it's quite fast for it's type due to the counter rotating props.

[Muku]

Counter rotating props have been around in marine engines for some time now too. Mercury makes one called "Bravo 3" here (http://www.mercurymarine.com/bravo_three2) is a look at it. There are several advantages to this type, except that it is obviously going to cost more. I'm actually very surprised I haven't seen too much in the way of this idea around in cooling. its a simple idea.

[squirrel9000]

Old thread, I resurrect you! (uses old thread resurrecting powers)

How did you attach the fan to the heatsink?

[BillA]

yea, what's the deal with our silver-tongued friend ?
got so busy chasing mythical silver that the MCX159 killer was abandoned ?

I am not sure but it definatly helps. There is some 220 CFM delta fan that uses that. I think it is only a 92mm too. I will go check that out.

EDIT:
Ok nevermind, it was a 120X120X78

[JKeefe]

Yes, please, what happened to our little freind?
