### Motherboard Compatibility
The Gigabyte B550 AORUS Elite V2 motherboard fits into the NZXT H5 Flow case as it supports the microATX form factor accepted by the H5 Flow.
### Number of fans installed
The NZXT H5 Flow case comes with one pre-installed fan. It supports up to eight fans in total, but only one fan is installed as standard.
The NZXT H5 Flow supports the installation of water cooling systems, but there are restrictions on the size of the radiators that fit.
- The case supports up to two 120mm fans or one 240mm radiator at the top.
- Up to two 140mm fans or a 280mm radiator can be mounted at the front.
- A 120mm or 140mm fan or a corresponding radiator can be mounted on the underside.
However, a 360mm AIO (All-in-One) water cooler does not fit in the designated mounting areas of the H5 Flow Case. The maximum supported radiator size is 280mm at the front and 240mm at the top.
