In theory it isn't a bad idea. PSUs do produce a lot of heat. I think it is more of poor judgment. You could reach the same end by mounting the PSU outside the case. All cooling really does is transfer heat from one place to another. Presumably inside the case to outside the case. Simply removing the heat source from inside the case should work better than trying to cool it. The flip side to that is that the PSU itself will still run at the original temp. I bet that there would not be a considerable gain in a lower operating temp (for a psu)
