TRYX ROTA PRO 140mm PWM Case Fan

The TRYX ROTA PRO 140 is a 140mm case fan built for builders who want strong airflow with low noise. It uses a 4-pin PWM connector for automatic speed control between 500 and 1650RPM. The fan frame is made from industrial-grade PBT and the blades from Liquid Crystal Polymer for durability. It suits standard case mounts, CPU air coolers, and AIO radiators.

Upgrade from stock or sleeve-bearing fans

This fan replaces basic 140mm fans that use sleeve bearings or lower static pressure. The jump is worth it when you need 2.53mmAq pressure for restrictive radiators or dense heatsink fins. It delivers 100.3CFM maximum airflow while keeping noise at 32dBA under full load. Buyers who need higher static pressure than 2.53mmAq or speeds above 1650RPM should look elsewhere.

Simple four-screw install with vibration pads

Installation uses standard 140mm mounting holes and includes four large noise-damping pads to absorb vibration. The fluid dynamic bearing and three-phase six-pole motor keep rotation stable. An extended cable is supplied for routing flexibility. The only common issue is ensuring the 25mm thickness clears nearby components in tight layouts.

Questions about this item

Does the 140mm by 25mm frame fit standard 140mm case mounts and AIO radiators?

Yes, the fan measures 140x140x25mm and is listed as compatible with cases, AIO radiators and CPU air coolers in push or pull configurations.

How do I connect the 4-pin PWM plug and the extended cable without mis-wiring the fan?

Plug the 4-pin PWM connector directly into a motherboard fan header; the extended cable simply lengthens the reach and carries the same four wires, so orientation stays identical.

When should I expect to replace the Fluid Dynamic Bearing or clean the LCP blades?

The FDB is rated for long life with no lubrication needed; clean the LCP blades with compressed air whenever dust buildup reduces the 100.3CFM airflow or raises noise above 32dBA.
