Performance
In terms of performance, the Pure Wings 2 140mm PWM fans exceeded my expectations. They provided strong airflow, keeping my CPU and GPU temperatures comfortably low even under heavy load. The fans remained remarkably quiet even at full speed, making them ideal for a silent PC build.
During gaming sessions, the fans didn’t kick into high gear and generate excessive noise, even when pushing my hardware to its limits. I found this to be a significant improvement over previous fans I’ve used, which often became noticeably louder under stress.
Pros & Cons
**Pros:**
* **Quiet operation:** The fans are remarkably quiet, even at full speed.
* **Strong airflow:** The 104 CFM airflow effectively cools your components.
* **Durable design:** The rifle bearing technology promises long lifespan.
* **PWM control:** Allows for precise fan speed regulation.
**Cons:**
* **Limited lighting options:** The fans lack RGB lighting, which might be a drawback for some users.
Final Verdict
Overall, I highly recommend the Be Quiet! Pure Wings 2 140mm PWM fans. They offer a fantastic balance of performance, noise levels, and durability.
