18+ degree drop in temps

This cooler, when using a push/pull fan configuration, has given me an 18-20 degree drop in temperature on my old Phenom 940. Granted, I was using a low profile cooler, but since I'm using a low profile case I couldn't use a tower cooler. Under Prime95 blend test the 940 is hitting at peak 42 degrees. The only con I can see is that it is priced too high. I got mine on sale. Also if you plan on using it for a low profile configuration, be mindful of the fact that you'll probably need to mount the radiator externally/creatively if interior space is an issue.
