A single 120mm SilentWings fan keeps all internal components thermally healthy. This is a sleeve bearing fan that only registers up to 28.5dBA at full load (~1350 RPM). Under 50% load, it barely registers any noticeable sound at only 14dBA. High-quality Japanese capacitors are used for longer life of course, and for efficiency. The more efficient the power supply is, the less cooling requirement it needs. Thus, the included fan does not even need to operate at high speeds, keeping a quiet operation.
