Ever since I've had my PC (approx. 1.5 years ago), it has always emitted a metallic smell when running hardware-intensive games. I have replaced my PSU, and GPU, both for unrelated reasons, and haven't noticed any difference. The smell is enough for me to catch a whiff of whenever I leave the room and l return to my computer chair, but isn't enough to be continually noticable afterwards (unless I have the door shut). I'm fairly sure this smell doesn't mean anything bad for my actual components, but from a health standpoint, I'm wondering how potentially bad it is for me to be inhaling this stuff. Is this kind of smell normal in high-end PC's or should I be looking to replace yet another part? Thanks.
