Closer Examination

The TRYX ROTA Pro comes in two colors as previously mentioned, and thus I decided to photograph one each of the black and white fans so you could better examine how they look. The fans obviously share a lot in common, including the LCP (liquid crystalline polymer) rotor in the default gray color and a reflective shiny front hub sticker that says "Empowering Possibilities" on it. The rotor has nine blades shaped clearly in a more static-pressure optimized application, which bodes well for my testing too. That said, the whole selling point of going with the more expensive LCP rotors is to allow the fan blades to get even closer to the inside of the fan frame than usual, which in turn means longer blades and thus faster velocity air being pushed through the fans. This is because LCP blades don't tend to creep outward over time, and thus won't hit the frame causing issues with performance and noise alike. The TRYX ROTA Pro gets close to the frame, albeit not to the extent that the leading performers using LCP rotors have done. There's a fixed cable coming out one side, and we also see anti-vibration rubber pads on the closed corners. The frame seems to be made of PBT plastic given the rougher texture and the overall 166 g fan mass, with the sides having the brand logo and arrows to indicate the direction of airflow if needed. This is otherwise a standard 120 x 120 mm square frame and is 25 mm thick, thus ensuring increased compatibility with other PC components. I also appreciate the frame, rubber pads, and cables come color coordinated to better match your preference and the rest of your PC build.


From the back we see a typical 4-way stator vane configuration leading from the hub which has a sticker that tells us the fan is rated for a max current draw of 0.22 A (2.64 W on the 12 VDC rail). This includes start-up boost, but even so I only measured a max power draw of 1.8 W per fan—you should be plenty fine running 3-4 of these off a standard 1 A fan header. TRYX tells us the fan uses a fluid-dynamic bearing, which is nice for longevity and performance, and also that a 3-phase, 6-pole motor is used which can help with operating efficiency. The product page is otherwise full of marketing jargon, some of which tests my patience. There's nothing remotely noteworthy about the corner pads or unique about the blade structure, for example. I do see something to talk about the stepped frame perhaps, but TRYX decided to ignore it altogether. Regardless, we see a 4-wire flat cable headed from the back hub to the frame, where it splits into a female 4-pin PWM header and a shorter extension cable going to a 4-pin male PWM connector. This effectively is a pig-tail solution to try and make daisy-chaining fans used alongside each other on a radiator easier, yet the solution is less than elegant as we see the shorter section is too long to be used directly and too short to go around the frame to the adjacent fan. The end result is a somewhat sloppy look with the fan cables hanging over the edges. The remaining male PWM connector can be used with the provided extension cable to power and control the group of fans together off a single fan header.
