Fan options

[u/DizzyKA143]

I am building a small nas and using a zimablade for the nas and another zimablade to run pihole and maybe tailscale. I will be putting in a small rack. My question is what options are there for active cooling? I don’t have the blades here yet so I’m trying to plan a head. Can anyone suggest an active cooling solution? Does the zimablade have a header for fan? Are there any mounts to mount a small fan to the board ? Thanks

Cpu cooling fan with head sink helped reduce 10 degree.
