I would separate the storage on a NAS like Synology and leave the core programs like Roon, Kodi etc on the PC - or get a dedicated device/ Mac or PC with less noise, fans, solid state drives etc to run Roon Core. Your issue will likely continue and may impact on both Roon and audio quality. Other option is to get a dedicated PC like device to run Roon RoonReady Sonore Sonicorbiter SE.
