Conclusion: With the change from the Vizo Igloo over to the Zalman CNPS 9700 LED, I didn't change the fan setting on the motherboard right away from FULL on smart fan. When I first powered up the computer with the Zalman heat sink, I was thinking that the noise was too much However, the temps were a nice 27C. With great temps come great noise; even in my computer filled office. So I switched things back to smart fan, and the noise level dropped considerably.
Pros: Well designed mounting bracket, Low 40 degree temps for full load, Easy to mount, Comes with the fan controller, Polished surface
