After researching replacement costs through local "fixit" places and Microsoft and cost ranging from $140 to $175 for fan replacement. Decided to take chance on this fan for Xbox one S. https://www.amazon.com/gp/product/B07HD3... Take time taking the bottom black plastic cover off once it gets started its easy. The corner by MS logo has tab that seems a bit thicker and took some doing to get off. Followed this guide did not have to do port removal. Once I got main white case off I just took hard drive and optical drive screws out. Just lifted enough to get to tab holding fan onto heat sink. popped them off and then replaced with this unit. Be aware when putting optical drive and hard drive back in place there are plastic tabs that match to holes on motherboard and let the two units sit down all the way. Also If I recall the hard drive goes in first and then  optical drive. 15 minutes from start to finish. Worked like a champ right off! thanks for the awesome guide!
