So when i get around the back of my pc and put my big ole' nose directly in the way of the air coming from the PSU i feel funny smell.
Using the pc normaly ,i cant smell anything ,but only whem i smell directly from the psu.
Is this normal?
No it's not normal at all. Did you get it used? There might be some organic matter or dust that is decomposing or burning. I would replace it just in case.
