I had to check the fan 3 times to make sure it was running. SilenX definitely lives up to their name. Both it and the 120 are virtually inaudible over other other components in the system. With the $8 buck price tag, sufficient cooling and significant noise reduction, we easily award these products our approval.deviceunknown review
These fans are easy to iunstall and performed much better than the stock fans in our benchmark tests while running quieter. It's the same series of fans used on their Effizio CPU coolers, which performed better than the stock heatsink at much lower noise levels, but available in multiple sizes and noise levels.
