And they probably will. There will be significant intergenerational improvements in the latest fans for relatively simple reasons. The higher airflow and higher static pressure at the same speed for the Toughfan Pro has a clear explanation in the design details Thermaltake has worked on. It’s quite possible that you’re looking at fans that finally beat the Noctua NF-A12x25<\/a> in efficiency, even with the same profile thickness.<\/p>\n

Thermaltake’s fan range is expanding with a new series \u2013 the Toughfan Pro. Compared to the existing Toughfan, the name “Pro” has been added to the name. This was done to indicate a technical advancement with more attractive parameters. While the Toughfan Pro at first glance seems very similar to the older fans (Toughfan), the changes in geometry are quite significant, you just have to take a close look at them. Since there hasn’t been a major change in shape, they are easy to overlook.<\/p>\n

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

The fan rotors still have nine blades with a more pronounced leading edge curve, this has not changed. What is different now (and will make a difference in efficiency) is both the larger area per blade and the smaller inter-blade spacing. Due to the former \u2013 the larger blades \u2013 the increase in airflow at the same speed is supposed to be up to 21%. At 2000 rpm, 120.3 m3<\/sup>\/hr is stated.<\/p>\n

Larger blades in the same cross-section also mean that the inter-blade spacing has been reduced and thus the static pressure naturally rises, so that the impact of the obstacle resistance on the airflow drop is smaller, reportedly by as much as 24.5% (to 3.19 mm H2<\/sub>O). Basically, this is an application of the first and second tips we once gave on the possible efficiency increase of the Noctua NF-A12x25 fans<\/a>.<\/p>\n

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

Also contributing to the higher static pressure is the narrowing of the gap between the tips of the blades and the frame to 0.6 mm (this is therefore half the size of the Toughfan 12<\/a>\/14<\/a>), so there is less cross-sectional area for air leakage, which is good. And whereas the Toughfan 12 is already close to Noctua’s elite 120mm fan in efficiency (though still lags behind), the Toughfan Pro will probably easily outperform it in terms of airflow and static pressure at the same speed. The question is at what noise level.<\/p>\n

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

By the nature of using thick blades made of solid LCP, the acoustics will not be adversely affected by excessive vibration at blade level. Anyway, the higher airflow here (in the Toughfan 12\/14 Pro) is somewhat achieved at the expense of higher noise levels. However, the increase in noise claimed by Thermaltake is only negligible, at 0.3 dBA. Whether it won’t be higher in the end, we don’t dare to guess. Noctua showed at Computex that it, too, has dabbled in prototypes in the past with very significant reductions in blade spacing<\/a>, but those haven’t translated into practice in such an aggressive form. Next to the Lian Li UNI Fan P28<\/a>, this is the second fan in a short period of time that has a realistic chance to be in the top 3 most efficient 120 mm fans..<\/p>\n

In the 140 mm format, where the competition is weaker, Thermaltake aspires to be at the very top with the Toughfan 14 Pro. We’ll cover this fan in our tests before Noctua releases a “sterrox” competitor that also looks great on paper<\/a>.<\/p>\n

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

The internal structure of the hub is also supposed to be more robust than it used to be (for the Toughfan 12\/14), with more steel used. Also new is the copper cover around the bearing, which, in addition to providing more stability for the axle, should also ensure a longer service life. The new hydraulic bearing is also expected to contribute to this.<\/p>\n

The suggested price for the 120 mm Toughfan 12 Pro is 22.90 EUR and for the larger variant (Toughfan 14 Pro) 25.90 EUR. The 2-packs (for 40,90 EUR and 44,90 EUR) come out a bit cheaper on a per-piece basis.<\/p>\n
