Delta Electronics 40mm x 28mm extreme speed 12V DC fan (model # FFB0412SHN). This type of fan is used in Sun Fire V20Z servers (P/Ns 370-6639,S00715). It can also be used in other systems that utilize the same size fan with the same type of connector. It comes with a 3 pin connector pictured & cables measure about 7" long.Since the item is used it may have minor cosmetics defects. I posted the specs below for reference.

Please note that this fan is not compatible with desktop PC motherboards. If you need a PC-ready version of this fan I have them available in my other listings. Just check out my other items.
