If the (single!) PSU fan is triggered by big heat from a CPU in the way of his air, one of the three central fan pairs should have got triggered to high speed too, and the second fan of the same PSU too. So the heat source (if ever, may be a failing sensor only) seems for me to be a local defect in one of the two PSUs.
