Gelid Zodiac fan: ARGB LED and excellent price/performance ratio

Cooling, Extra tests, Fans | | Ľubomír Samák

Gelid Zodiac in detail

Aside from whether the fan is named after the zodiac or a serial killer from California, we know all about Gelid’s latest fan. In the end, the inspiration may stem from the latter as well. After all, it has a backlight option and at the same time “kills”, performance-wise, the price-equivalent fans without it. And attractive models at that. But there is one thing that can erase all the good features.

We’re going to give the Zodiac Gel test a bit of a broad brushstroke, but you’ll quickly see where we’re going with it. We can probably agree that illuminated fans are for a slightly different target audience than traditional, non-LED fans. Manufacturers often tailor their parameters and overall marketing activities according to this.

You have witnessed many times that with otherwise similar fans, the illuminated variants usually have slightly worse claimed parameters. Whether it’s the latest case of Antec’s new products, Akasa or even BeQuiet! Light Wings are not supposed to be more effective than Silent Wings 3. It’s a pretty natural segmentation, where some fans (with RGB LEDs) have to sell visual features while others (without RGB LEDs) have to sell functional features. And that’s when it’s naturally appropriate that their parameters are in the line above the illuminated fans.

However, the current centre of attention, the Gelid Zodiac fan, has illumination, a very high indicated air flow (111,29 m3/h) and also costs only ten euros. The performance, or let’s say rather the efficiency (it’s relatively easy to set absurdly high speeds, but to achieve efficient operation with an impressive performance-to-noise ratio already requires a knack) is supposed to be higher than that of the BeQuiet! Pure Wings 2, which is a fan for the same money, but without the light show options. And that is remarkable.

Tvar rotora je podobný ako u ventilátora Arctic BioniX F120, ktorý, ako už viete, veľmi výrazne brzdia prekážky. Lopatky Gelid Zodiac vyznačuje takisto relatívne menší sklon (aj keď je o trochu väčší než u BioniX F120), ale zase sú po celej dĺžke širšie. Menšie sú tak medzi lopatkami aj vzájomné medzery, ktorých rozstupy sa, samozrejme, podieľajú na intenzite vzduchu, ktoré je ventilátor schopný pretlačiť cez prekážku.

The static pressure will not be that high here. JFirstly, the ends of the blades have a relatively large spacing from the frame of about 2.5 mm, but also in the parameters Gelid lists a relatively low 1.48 mm H2O. It should be added that the blades are quite flexible and soft. In flight, especially at higher speeds, they will be subject to more deformation, which does not add to the performance.

Considering the lower price range and the fact that the fan has up to twelve brightly colored LEDs, the build quality is definitely above standard. There are no chips left on the edges, which indicates the higher quality standard of the injection mould. The frame is also solid, and what’s more, there are also rubber pads in the corners to eliminate vibrations. They are also made with a relatively soft material (with a hardness of approximately 35 Shore), so they will be quite effective as well.

   

However, we did not expect significant vibrations due to the use of hydrodynamic bearings, but these are naturally related to centering accuracy and, in lighter designs, turbulence. At 126 grams, the Zodiac’s weight is rather below average for the proportions of 120mm fans.

Before we get into the analysis of the results, let’s praise the long (50 cm) flat cables and up to two ARGB LED connectors. The second one, for connecting in series, will certainly not be lost in current PC setups.

* 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.

Slowly but surely, the Arctic P14 fan tests are coming up. In a short time sequence we will analyze all models that differ from each other more than the color design. After testing the base model, we’ll look at how the use of ball bearings (instead of fluid bearings) affects the results, culminating with the P14 Max framed impeller. That this fan must be the most efficient? Not necessarily. Read more “In the works: Trilogy of different Arctic P14 variant tests” »

BeQuiet! put all their modern fans in white

Cooling, Fans, News | | Ľubomír Samák

Both 120 and 140 mm BeQuiet! fans from the Silent Wings (Pro) 4 and Pure Wings 3 series are now available in an all-white design. So both more expensive and cheaper fans, which have in common a very high airflow per unit of noise. Across the entire price spectrum, you are dealing with some of the most efficient fans you can buy for computers. And not just among the white ones.

New Arctic P14 Max: Anti-vibration and high speed

Cooling, Fans, News | | Ľubomír Samák

Those interested in 140mm fans have reason to rejoice. After the P12 Max, Arctic is also releasing the P14 Max, which is one size larger. These stick to the already established features, such as a significant speed increase, but also probably a noise reduction even at low speeds. By all accounts, these should be universal fans that will be efficient across the entire speed spectrum, and on all types of obstacles.
