I cant see in the photo is thats a 80mm or 60mm.
You can't go wrong with the Noctua Fans they pricey because of the shipping but you will not be disapointed. They the best of the best installed two in my Growatt.
The pins will be different as the Noctua are meant for PC and Servers, you will have to use the old connectors.
