As far as the power supply fan is concerned, their manufacturers don't care about improving its efficiency. This is because you are not the real customer. Dell, HP, et al are. When they place an order with the metal-bending shop in China, all they care about is price. If putting a more efficient fan in the power supply is going to raise the price by a few pennies, they won't be interested.
The only way anything that the high-efficiency power supply is going to fly is if it is going into a high-end product.

If Google can shave .5 percent off their electric bill by using a more efficient cooling fan on PSU's going in to their server farms, it's worth it to spend a fair amount to realize that savings, especially since they know their usage is going to grow.
