Antec NeoECO 750W Modular 80 Plus Gold Power Supply Review

Fan Speed

This PSU has two fan modes, the first is an active fan, which operates at 800 RPM at lower loads, and peaks around 1600 RPM at full loads. The fan is audible at full speed, but it’s a good quality fan that wasn’t really any louder than a typical case fan. In hybrid mode, however, it stayed at 0 RPM until we hit 80% loads for a few minutes, then it started at 800 RPM, only going up to 1550 RPM when the PSU was left running at 100% loads for a period of a few minutes. Overall though, I’d be happy to leave it in Hybrid, as the PSU never seemed to actually get noticeably warm anyway, given it’s only outputting up to 750W.
