The be quiet! PURE LOOP 3 is an all-in-one liquid cooler for desktop CPUs with a 140 mm fan and a black finish. It provides compact, maintenance-free liquid cooling for Intel and AMD processors, supporting a wide range of sockets including LGA 1150/1151/1155/1200/1700 and AM4/AM5, and operates from a 12 V supply to lower CPU temperatures and stabilise system performance.

Advantages

The all-in-one design integrates pump, radiator and fan into a single unit for straightforward installation and no regular maintenance. The 140 mm fan balances airflow and acoustic performance to reduce noise while improving heat dissipation. Universal socket compatibility covers many Intel and AMD desktop processors, making the cooler suitable for upgrades and system builds where effective, quiet cooling is required.

Suitable for

• Gaming desktop PCs requiring efficient CPU cooling
• Workstations and content-creation rigs
• System upgrades to replace air coolers with liquid cooling
• Quiet or compact builds where reduced noise is important
