Yay. Why not just use one really fast fan? Im sure it would work even better, it would be noisier but if you are going to do that you dont care about nosie anyway.

Nor about airflow, those fans are just going to fight against each other no matter how you arrange them.

Wrong!

The fan on the north blows south. The fan on the south blows south. They're aiding, not fighting. The fan on the east blows west. The fan on the west blows west. They're aiding, not fighting. Net result: air from the northeast moving southwest. All 4 fans aiding this air movement.

Is this how hurricanes are started?

North/south fans are flowing south, at the same time east/west fans are flowing west? Sounds like a conflict to me.

Yep !
A typical 2 fan push - pull would definitely work better and quieter IMHO.
4 fans is pointless and counter productive ...

And what's really amazing is they are all blowing air inwards.

I would definitely like to see that theory put to the test....

(personally I think you would seriously have to finetune both fan speeds to avoid counterproductive turbulence)

Not that difficult. If you use two similar fan at identical voltage then there should beminor variances between CFMs. Which the opening on sides can compensate for easily.

As far as the other post is concerned (all fans blowing inwards) : WTF

Are we trying to presurise a rad here ? Maybe that can prevent the heatpipes from leaking over time ...

It's probably just a dumb marketing geek/photographer, trying to show that you can mount a fan anywhere you want, with no mounting conflicts if more than one is used. Note that that is not a pic of the HS actually installed in a system, just a glamour shot for advertising.

Still dumb, though.

Jab-tech seems to think these are worth offering for sale. They also offer the 2-fan version. Currently out of stock (fan clips en route?).

yes

It is also how fools and money are seperated.

Unless a person is computing the trajectory for a NASA space shot on an overclocked Prescott Bun Warmer,the only reason to stick 4 fans on that is to keep insects out of the heatsink.

I think its not really worth of the money. Infinity is still heavy HSF. I mean its 960 grams. If average 120mm fan is, let's assume around: 130g, that x 4 = 520 grams.

Combine HSF weight to fan weights: 1480 grams! which is attachted with VTMS. But that sounds seriously risky to me. Definately not Lan worthy. I think you're better off with Antec P-180, put Infinity with 1 fan spinning and use P-180's dual exhaust. Less changes damaging your motherboard.

with 4 fans ud end up with an "X" like fan path and the 2 airflows from the two fans pushing would crash making a horrible path of air flow... now 2 fans pulling air though it wouldnt be bad as long as the fans where put in the shape of an "L"

spookmineer · Post by **spookmineer** » Mon Feb 26, 2007 4:11 pm

Maybe the airflow path will be more towards a " ) ( " situation, but it's hard to measure anyway.

It doesn't seem like this multi-axis fan arrangement makes sense. However, it could conceivably make sense to want to generate airflow in an unusual direction. Perhaps a HSF could be designed such that the tower and fan assembly can rotate about the contact plate and retention assembly. The difficult part would be designing a locking spindle that transmits heat efficiently. A beefy central heatpipe would double as the axle. Then you would be able to rotate the HSF 360 degrees, possibly even without un-mounting.

The engineer in me says this is a good idea, but the project manager on my other shoulder says they'd never make any money on it.
