Article Summaries:
- Be Quiet’s Silent Loop 3 420, a 420 mm AIO cooler, delivers strong cooling while staying quieter than many competitors. The unit features three 140 mm Silent Wings 4 fans (up to 1900 RPM, 78.4 CFM) and a large CPU block that supports Intel LGA 1700/1200/115x and AMD AM4/AM5/TR4/TR5 sockets, including Threadripper. It includes extra coolant, a refill port, and optional ARGB lighting on the block. At MSRP $189.90 (often $139), it offers solid performance for >260 W TDP loads, but only a small amount of thermal paste is supplied. Tom’s Hardware notes its DIY friendliness and low noise as key strengths.
