This is a good CPU cooler for servers and high-performance workstations. I tested it on an Hp workstation and the fan was not noisy, not as noisy as the Dynatron CPU cooler fan. This CPU cooler is top notch. The next test of this CPU cooler takes place on an Asus mainboard. Updated 05/07/2018. I installed a Silverstone CPU cooler on an Asus motherboard and it offers cooler CPU temperatures than the standard Intel CPU cooler I installed and it's very quiet and was very easy to install.
