This article covers Be Quiet Silent Loop 2 120mm.

Overview

The be quiet! Silent Loop 2 120mm is a compact all-in-one liquid CPU cooler from the German PC cooling specialist be quiet!. It is designed to deliver excellent cooling performance while keeping noise levels exceptionally low. The 120mm radiator and specially developed pump work together to achieve a noise output of just 35.9 dBA, making it one of the quietest coolers in its class. The cold plate is made of copper and the radiator uses aluminum, ensuring reliable heat transfer and long-term durability. This cooler supports Intel LGA 1700/1200/115x/20xx and AMD AM5/AM4 sockets, making it compatible with most modern CPUs. Its compact 120mm size fits into many smaller cases where larger radiators cannot be installed, offering a balance of cooling capability and space efficiency.

Connectivity & Compatibility

The be quiet! Silent Loop 2 120mm includes mounting kits for Intel LGA 1700, 1200, 1150, 1151, 1155, 1156, 2066 and AMD AM5, AM4, TR4 (Threadripper requires a separate version). The pump uses a 3-pin connector, and the included 120mm fan has a 4-pin PWM connector for automatic speed control. Radiator dimensions are 157mm x 120mm x 27mm (W x H x D), fitting most ATX and some Mini-ITX cases. The pump operates at 12V with a power consumption of only 1.92W, placing minimal load on the power supply.

Product Info

Released in June 2021, the Silent Loop 2 120mm has been a steady seller in the entry-to-mid-range liquid cooler market. Its key selling point is the extremely quiet operation backed by be quiet!'s engineering reputation. The warranty period is 3 years, covering any coolant leakage. The package includes one fan, mounting hardware, pre-applied thermal paste, and an installation manual. Coolant is pre-filled and sealed, requiring no maintenance.

Best Use Cases

This cooler is ideal for users who prioritize silence above all else. The low noise level (35.9 dBA) makes it suitable for quiet home offices, media centers, or living room PCs. It's also a great choice for building a compact system where a 120mm radiator is the maximum size that fits, providing better cooling than a typical air cooler in tight spaces. For heavy overclocking or high-TDP CPUs, a larger 240mm or 360mm AIO would be more appropriate. The Silent Loop 2 120mm is best suited for mainstream CPUs running at stock or mild overclock speeds.
