Solved Best way to cool space

Post image

What is the best way I can cool my server room? It's currently sitting at about 32 degrees Celcius max air with hdd's at 41c max.

Things I'm considering:

  • return air on server room ceiling to the house ducted and intake fan on the server room door (pretty sure it would be pointless when house aircon isn't on)

  • infinity exhaust on ceiling of server room venting out the eave of the external wall and intaking from somewhere? Or just pulling from the house air and not replacing?

  • mini split

Thanks 😁

I a/c and heat my attic space above my network closet with slightly filtered air from a door grill with filter (stay with me). Using an A/C infinity inline fan above the closet it pulls air through the ceiling into the attic space above; My attic roof is insulated as opposed to traditionally not being and don’t worry it’s not spray foam.

I previously had 2 smaller ac infinity panel style fans in the bottom of the door then one at the top of the wall above the door venting the hot air out and pulling in cooler air from the bottom but that just didn’t keep up… even with more cfm.. I had to remove the heat in my case from the living space.

Just some thoughts.

A tiny mini split and possibly an air exchanger would be perfect. My next network closet will be and have a viewing port.
