This 3-pin fan boasts a size of just 40mm in diameter, making it an ideal choice for space-constrained applications such as small form factor PCs, servers, or other equipment where space is at a premium.
The Noctua NF-A4 FLX is equipped with a 12V power supply, ensuring it can deliver strong performance efficiently.
