Seasonic MagFlow ARGB: Lighting with LCP? The right way

Cooling, Extra tests, Fans | | Ľubomír Samák

A concept in which an LCP impeller and ARGB LEDs meet is particularly rare. But it has enormous potential for achieving top-notch results. That is, as long as everything fits together optimally and there are no weak spots somewhere that increase the noise level. There are still a few things to tweak with the MagFlow ARGB fan, but already now, in its current form, it is a premium fan, and not only among lighted models.

* When reading performance values, a certain amount of tolerance must always be taken into account. For maximum speeds, ±10 % is usually quoted, minimum speeds can vary considerably more from piece to piece, sometimes manufacturers will overlap by as much as ±50 %. This must then also be adequately taken into account for air flow, static pressure and noise levels. If only one value is given in a table entry, this means that it always refers to the situation at maximum speed, which is achieved at 12 V or 100 % PWM intensity. The manufacturer does not disclose the lower limit of the performance specifications in its materials in that case. The price in the last column is always approximate.
** Price calculated per unit, but the fan is not sold separately. It is only available as part of a three-pack that also includes an ARGB hub.

Fan frame daisy-chaining trend. When is it (not) helpful

Analysis, Fans | | Ľubomír Samák

Easier installation? Yes, that’s why it’s done. Daisy-chaining fans using contacts in their frames is great, but it often also comes with pitfalls that reduce “cooling efficiency”. Manufacturers deal with this in different ways. One does it technically one way, another differently. In any case, they know that a frame that is too thick means less space for the blades. And that does not improve airflow per unit of noise. Read more “Fan frame daisy-chaining trend. When is it (not) helpful” »

Arctic BioniX P14 A-RGB: Elegant daisy chaining is just the beginning

High cooling efficiency is the foundation, but with the BioniX P14 A-RGB fans, Arctic has also made efforts on other fronts. In addition to the clever daisy-chaining method (with the aim of reducing cabling to a minimum), this includes, for example, illumination as intense as possible. The light is guided not only through the entire impeller, but also through the surface of the frame, from the side. There are light guides in these areas as well.

And with very clever daisy‑chaining from one fan to the next. This is what can fill in the ellipsis in the headline. The aerodynamic efficiency remains top‑tier, built on a design that Arctic revised some time ago (with the P12 Pro fans), but which can still be considered “new.” The BioniX P12 A‑RGB fans certainly are (new), and in this in‑depth analysis we focus on how they work.

  1. Hmm, that’s worse than I thought for an LCP fan with Gentle Typhoon-like rotor, only trading blows with the much cheaper Arctic P12 ARGB. Perhaps the impeller footprint is the main culprit here, alongside the motor and bearing.

    Comparison with the Grand Tornado would be interesting, as they represent two extremes of impeller footprint while having similar blade geometry.

    1. Yes. Thank you for the heads-up, we have added one more negative to the +/- table, namely that the vibrations at some speeds are higher than they could be for the standards of LCP fans. There is probably some imperfection at the level of the bearings, for which this happens in combination with this impeller.

      I have no doubt that the impeller itself will be well aligned and the fault will be elsewhere. At the same time, it won’t be some random thing, as these fans behave identically across different samples. It’s hard to say where exactly the weak point is, but maybe it could be suppressed or compensated for in some way. For example with balancing inserts, like the Phanteks T30. And maybe they wouldn’t help at all, there’s probably no point in speculating here and you just have to accept the fact that the vibrations can sometimes be higher for an LCP fan than one would expect.

      Still, this is only Seasonic’s second fan and I have no doubt that with each new one more and more flaws will be removed and eventually the result will be very positive. We gave them a tip for an “Arctic P12 with an LCP impeller”. Personally, I would be very interested to see how such a design, with a very precise build, would stand up to, for example, the NF-A2x25 or the T30. I guess it might not be a bad thing, since even the P12, with its noisier low frequencies, which could be significantly suppressed after blade stiffening, ends up at the top of the performance charts. The question is whether with a significantly heavier impeller the small hub could be retained, as it could probably cause some instability.
