Modern PCs run fast, with more powerful CPUs, GPUs, RAM, and storage dropping every year. With that, the focus on acoustics has become increasingly important. GPUs, for instance, have had “silent” modes for over a decade, where the fans remain off when the load is low. Some PSUs have adopted this as well, with a Hybrid or Zero RPM mode keeping the PSU silent when the load is low. But this design can be problematic in some cases.
