It arrived quietly, but we had been looking forward to it for a very long time. In its form factor, the Phanteks T30-140 fan works wonders and often defeats everything that stands in its way. Yes, even the Noctua NF-A14x25 G2 PWM<\/a> is often the \u201cnext in line\u201d, albeit at the cost of a thicker profile. Airflow is exceptionally high (and consequently cooling performance) through obstacles. Larger fans now have a new dominant model.<\/p>\n

We truly waited a long time for the Phanteks T30-140<\/a> fan, but it\u2019s finally here. That means it\u2019s time for a detailed analysis. What makes this fan so exceptional? It combines features expected to deliver extraordinarily high cooling efficiency across various scenarios. First and foremost, it\u2019s the efficient geometry of the strongly curved blades, which from past experience (with fans using similarly shaped blades) we know excels in the airflow-to-noise ratio. In other words, relatively high airflow is achieved per unit of noise.<\/p>\n

High (aerodynamic\u2014or rather cooling?) efficiency is also supported on obstacles by the above-standard 30 mm profile thickness. This parameter increases blade surface area, but more importantly contributes to higher static pressure.<\/p>\n

\"\"<\/a><\/p>\n

Static pressure is further supported by relatively small gaps between the blades and an overall small idle cross-section. This includes, for example, the small clearance between the blades and the fan tunnel. In flight, it is only around 0.8 mm. Measuring this precisely is quite complicated, but ultimately what matters is the output result. The mentioned gap is just one of many elements intended to help achieve the most attractive real-world performance possible.<\/p>\n

The fan is made from liquid crystal polymer (LCP), an exceptionally rigid material. Such a structure is also useful for suppressing unwanted vibrations<\/a>, thereby preventing noise increases at this level. The overall mechanical execution is, of course, excellent as well. The Phanteks T30-140 is a truly robust fan, weighing approximately 270 grams.<\/p>\n

To set different speed ranges, there is a switch on the motor housing. By default, it is in the \u201cPerformance\u201d position with approximately 340\u20132045 RPM. Maximum airflow is achieved in the \u201cAdvanced\u201d mode, where you reach speeds of around 2500 RPM<\/a>. The lower limit (~340 RPM)<\/a> remains unchanged. That only changes in the \u201cHybrid\u201d switch position, where the range is the narrowest. Not only are maximum speeds the lowest (~1212 RPM), but minimum speeds are also the highest (~547 RPM). This is what we recorded in measurements. After exceeding a certain PWM duty cycle threshold, the fan switches off, so support for \u201csemi-passive operation\u201d can be confirmed.<\/p>\n

\"\"<\/a><\/p>\n

Motor power is nearly 20 watts<\/a>, which is extraordinarily high, and in some situations an intake grille would be advisable for safety reasons. Especially at maximum speed, unintended object ingress into the fan could have devastating consequences. In terms of maximum operating power consumption, it is approximately 6.3 W<\/a>, meaning more than 500 mA per fan.<\/p>\n

With three fans (typically in the case of triple packs), you are already above 1 A<\/a>, even without considering inrush current, which is naturally even higher. When connecting three fans to a single motherboard header or hub, keep this in mind. The fan\u2019s design accommodates such installation quite well, as the short cables (approx. 15 cm) feature two connectors\u2014one for the fan\u2019s own power supply, the other for connecting the next in sequence.<\/p>\n

The accessory package also includes longer screws (with UNC 6-32 threads) for radiators.<\/p>\n
