The stock fan is way too loud and not very efficient.
I replaced mine with Noctua NH-L9x65 and it’s super silent and cold now.
To do so I had to cut the connector’s plastic a bit so it would fit into the 4-pin connector on board and 3d-print standoffs between the fan assembly and the motherboard and the bottom plate.
The box that the fan comes with has a compatible bracket and is easy to install. You need to have a certain height for the fan to stand on, so I 3d-printed the standoffs or you can buy them instead. There are also standoffs required on the bottom of the MB so the back plate does not touch any of the components and does not short.
