Over the last few days i keep hearign this LOUD noise (like a whirrr...)coming from my pc. Most likely from my power fan unit. Is it dying? and how easy is it to install a new one? I have a mesh pc, asus a7ve, 1.2 athlon.
It is most often the PSU fan that packs in first. You can try (briefly only) stopping the fan with a pen, or the like. If the noise stops - that's the one. PSU fans can be changed - BUT ONLY IF YOU KNOW WHAT YOU'RE DOING - DANGEROUS VOLTAGE INSIDE A PSU EVEN WHEN DISCONNECTED.
New PSUs are not too expensive - but get a quality one - it pays in the long run.
