Notes

Caution: The round-frame NF-A12x25r features a custom hole spacing of 93x83mm. Therefore, it is not suitable for applications that require the standard 105x105mm hole spacing of square-frame 120mm fans such as PC cases, water-cooling radiators or CPU coolers with fan clips for square-frame 120mm fans. Please choose the regular, square-frame NF-A12x25 for these applications.
