Description

Description

The Be Quiet! SILENT LOOP 3 is a high-end CPU water cooling system with three 120mm fans, designed for maximum performance and silent operation. It supports AM4, AM5, 1700, 1200, and 115x sockets, covering both AMD and Intel processors. It features ARGB lighting, offering impressive aesthetics, while the optimized pump ensures excellent thermal performance with low noise levels. The Silent Wings 4 fans provide high airflow and static pressure, ensuring ideal cooling even for overclocked systems. With premium construction and the ability to refill the coolant, the SILENT LOOP 3 is a top choice for demanding users who want efficient and quiet cooling.

Features

  • The 6-pole motor with 3 phases and the 3-chamber design ensure that the pump causes less vibration.
  • Adjustable pump speed to suit individual needs for silence and performance
  • Effective pump damping reduces noise even when the pump is at maximum speed
  • Up to 3 Silent Wings 4 high-speed PWM fans for nearly silent operation at normal speeds

Tube Length
400 mm

Tube Length

The Tubing Length (mm) indicates how long the tubes connecting the pump to the radiator of the liquid cooling system are, and it directly affects the ease of installation inside the case. A longer length offers more flexibility in radiator placement (e.g., in large cases or in different positions such as the top or front), while a shorter length results in a more “compact” setup but with limited placement options.
Radiator Material
Aluminum

Radiator Material

Aluminum
Aluminum radiators are lighter and more affordable, making them the usual choice for AIO liquid coolers, with good performance for everyday use and easy integration into most systems.

Built-in display on the pump for viewing temperatures and statistics. Allows full customization with your own designs or animated GIFs.

Technical Specifications

Fan Speed (max)
2500 rpm

Fan Speed (max)

The fan speed determines how fast it spins, affecting airflow and noise level.

  • Low (500-1000 RPM): Quiet operation, ideal for low-noise builds, but with less airflow.
  • Medium (1000-1800 RPM): Balanced performance between cooling and noise.
  • High (1800+ RPM): Maximum airflow, suitable for demanding conditions or overclocking, with increased noise.
Fan Noise Level (Full Load)
19.8 dB

Fan Noise Level (Full Load)

The Fan Noise Level (Full Load) indicates how much noise the liquid cooler’s fans produce when operating at maximum speed, that is, under full load. It is measured in dB(A), and the lower the value, the quieter the operation. This is an important feature for those who want a quiet system, especially in demanding uses such as gaming or rendering where the fans run at maximum.
Air Flow
76.7 cfm

Air Flow

Airflow (CFM) indicates the volume of air that the fan moves per minute (Cubic Feet per Minute) and directly affects the cooling performance of the radiator. The higher the value, the more air passes through the radiator, contributing to better heat dissipation, although it is usually accompanied by increased noise.
Air Pressure
3.96 mmH₂O: millimeters of water

Air Pressure

Air Pressure (mmAq) indicates the force with which the fan pushes air through obstacles such as the radiator and is measured in mm of water column. The higher the value, the better the fan can penetrate the dense fins of the radiator, making it more efficient for water cooling compared to regular case fans.
Bearing Type
Fluid

Bearing Type

Fluid
Fluid Bearings use a thin layer of lubricating fluid for rotation, offering smoother and quieter operation, with a good balance between performance, noise, and lifespan.

    Purchased for a 9800X3D, so far (1.5 months of use) the temperatures are excellent in all scenarios.

    I got it because the case I use only supports liquid cooling and not air cooling. It has been excellent so far and relatively quiet, without me tweaking anything in the BIOS. The installation was very easy, it has everything you need inside, and generally makes very good contact with the processor. The instructions are very good and leave you with no questions. The lighting can be adjusted from the motherboard very easily and is generally discreet compared to others, which won me over when I made my choice. Overall, I highly recommend it, and a big bonus is the fact that it is one of the few that you can refill with liquid after 2-3 years of use, which makes you feel extra secure about its performance over time!

    Coming from the Ak400 digital cooler, I decided to switch to liquid cooling mainly for the aesthetic aspect but of course also for temperatures. Ryzen 7 9700x (stock CPU without PBO and generally overclock) was at 39-41 degrees idle before, and in gaming (Dota 2, Elden Ring, Days Gone) it reached 68-72 degrees. Now it’s 33-35 degrees idle and in gaming I didn't see above 55 (60 spike for a few seconds). Cinebench raised the CPU score since it’s cooler and peaks at 53°C. Amazing liquid cooling, beautiful and sturdy, easy installation, and you can top up the liquid after 2-3 years and it’s like new. And last but not least, the pump has a max speed of 3500 RPM, I set it from BIOS to 80%, around 2900-3000 RPM, and you can't hear ANYTHING.
