Up for sale is a lot of 4 screws for mounting a cooling fan (140mm or 120mm) into the front of Corsair Carbide 100R computer cases. These are leftovers from builds which did not require a front cooling fan. They are from Corsair Carbide 100R cases, but may be compatible with others. Please check with Corsair for compatibility with your case BEFORE you purchase this item. These are unused leftovers from system builds. The manual page shown in one of the pictures is NOT included – it is just there to show you how these screws are designed to work with the Corsair Carbide 100R case.
