Have ordered the fan in 2x execution. Once a board with Intel socket 775 and a second time for a board of AMD. The fan is really very quiet, even under full load not even hear him, if you do not leans directly to the housing. It should be said that the computers are under desks. The installation of the board of AMD was not a problem. In contrast, Intel was extremely complicated because the mountings for the socket 775 with enormous pressure to be closed because the brackets are simply inappropriate. Ultimately, it worked, but it was partly fear doing so exert a strong pressure on the board. The computer was running and running but still so broke by nothing.
Pricewise there is nothing to complain about and the delivery took place within good 18 hours. I know that Amazon but also otherwise. I recommend the fan, the Socket 775 you have to focus on difficulties, but make what concerns the installation. But would buy it again at any time. And maybe the brackets are later further optimized.
Due to the complex installation at 775 base there is a point deduction. In addition, the thermal grease would calm can therefore come in a tube. Nevertheless, an excellent product.
