Dynatron N11 2U Active Cooler for Intel 4189 up to 270W

Dynatron N11 — 2U Active Cooler for Intel 4189

Efficient cooling is essential to maintain the performance of servers under heavy load. Designed for Intel processors with FCLGA 4189-4/5 (Socket P4/P5 or P+), the Dynatron N11 supports TDP up to 270 W, ensuring reliable heat dissipation even in the most demanding conditions. Thanks to aluminum fins with built-in heat pipes, it offers excellent thermal properties. This cooler is an ideal choice for servers from 2U and above, where performance, durability and compact design are emphasized.

Cooling performance and efficiency

The built-in fan with dimensions 60 x 60 x 25 mm reaches speeds of up to 8500 RPM, allowing for efficient airflow. At maximum load, the airflow reaches 40.60 CFM, which is key for optimal cooling. Even at high power, the cooler maintains noise levels at an acceptable level — at 100% load, it reaches a maximum of 50 dBA, which minimizes interference in the working environment. The integrated 2-ball bearing extends the fan's lifespan even during continuous operation.

Power and compatibility

The Dynatron N11 cooler is powered by 12 V, which ensures stable and reliable performance. To control the fan speed, it uses a 4-pin connector with the following connection:

• Pin #1: Black (Ground)
• Pin #2: Yellow (+)
• Pin #3: Green (Tachometer / Signal Output)
• Pin #4: Blue (PWM).

This system allows precise control of the fan according to current temperatures, thereby optimizing cooling performance and reducing energy consumption.

Air Pressure and Thermal Conductivity

The cooler achieves an air pressure of 14.58 mm-H2O at maximum load, improving cooling efficiency in environments with limited airflow. For maximum heat transfer, the base of the cooler is pre-coated with high-quality Shin-Etsu 7762 thermal paste, eliminating the need for manual application and ensuring perfect contact with the processor.
