Seasonic’s second fan expands the range of lighted models. But it does so in a very non-violent way that doesn’t require lower impeller stiffness. The latter, on the contrary, is extra rigid, made of LCP, and compared to the older MagFlow 1225 fan, the shape of the blades has also undergone a change. The elegant magnet connection method that Seasonic prides itself on has been retained.
Seasonic has followed up the original MagFlow fan with a second 120-millimeter model. MagFlow ARGB also wants to appeal with ARGB LED lighting. You can see in its design that Seasonic was happy with the mounting system for chaining multiple fans. The contacts are still in the frame and adjacent fans are held together via strong magnets. Thus, to connect multiple fans to the motherboard or to a hub, a single cable, from the outermost fan, is all that is needed.
The fan frame is virtually as it was (on the Magflow 1225 fan) , but there is one cosmetic modification. Namely, the addition of a light-conducting strip that lines the impeller through the centre of the stator tunnel.
The next and last light guide then extends around the perimeter of the impeller hub. A total of 26 LEDs are used and it can also be stated that their implementation does not disadvantage the impeller in any way, as is usually the case with fans that use “milky” blades. These are dark in this case, they will not conduct and reflect light so well, but the undeniable advantage here is in high rigidity and low thermal expansion. In other words, vibration on the blades won’t be an issue even with this new geometry.
While the MagFlow 1125 had blades with shorter leading edges, the blades here are already quite long, more aggressively curved. Actually similar to the ones you know from most modern fans. Along with the extension of the blades, the thickness of the material has also increased and the MagFlow ARGB fan makes a really good impression. And among the lighted competition, the use of LCP is a bit of a rarity as well. The second such fan (120mm fan with LCP impeller and ARGB LEDs) is perhaps, if we haven’t overlooked anything, is only the Thermaltake Toughfan 12 ARGB.
The reported maximum airflow is relatively lower, at 2000 rpm “only” 84.05 m3/hr. At comparable speeds, the airflow of most fans is higher, but what matters is at what noise level. This is where the MagFlow ARGB may have an advantage due to the “quieter” impeller. The lower airflow is obviously due to the smaller cross-section of the impeller itself, which within the fan format (120mm) has some of its area cut off by the thicker walls of the frame with magnets and ARGB LEDs.
The static pressure is supposed to be 2.28 mm H2O. Seasonic is talking about using this fan on radiators, but it will be suitable for system positions as well. The MagFlow ARGB is claimed to have a MTBF of 100,000 hours. The bearings used are fluid dynamic bearings (FDB). MagFlow fans will be available in the first quarter of 2024, but we already know the MSRPs. In the case of a single fan it is 33.90 EUR, for a triple-pack it is 99.90 EUR. It also includes an ARGB LED hub.
