Excellent value for money
I've been a long time faithful to this brand for my 120mm, I've had them for more than 8 years, these ones are much more efficient compared to the UCTB12 which are already very good. The detachable blades had guided my choice at the time, that alone is appreciable, and I hope they will last at least as long. In fact I got these new ones just because they have 4 pin connectors instead of 3. Performing well at low speeds and totally silent up to 80%, they are a little bit loud at 100% but it's very reasonable and for my part I only reach 100% at the time of testing or on very rare and brief occasions. This should be the case for everyone. The addition of vibration dampening pads and cable sleeves are a nice touch compared to the UCTB12.
