received on time, great product, accuracy nikel sink! the only flaw is maybe the double-sided tape to secure e voi but I do not how to fix it otherwise. I have instaled on my raspberry pi b + overclocked to 1100MHz (CPU), 600MHz (sd card), 480MHz (GPU) in addition to a small fan coupled with a 2A 5V supply. Use Media Center in my raspberry does not exceed 35 degree 40 degree against before. therefore gain 5 degree which is satisfactory.
