Scythe Andy Samurai Master 6 Heatpipe CPU Cooler
 

I was extremely pleased with the Andy Samurai Master Cooler. The quality of the construction is excellent, the base is very smooth and flat, and the whole cooler is light in weight. The installation was so incredibly easy, it only required a few quick steps, and nothing had to be removed from the case to install it. On top of that, the performance was great. Although fan noise was not completely silent, it was rather low and, in fact, much lower than the three heatsinks tested against it
