Oh yeah that makes sense, the board does come with a shroud, my fans just don’t have the power to push air through it well.

Oh yeah it def had the SAS Backplane wires, I’d switched to using the SATA on board since it doesn’t have the same HD capacity limits. I think it was a max of 2tb with the backplane and I’m using a couple of 10tbs. Maybe their is some weird bios that requires it to be on board?

Hmm I’ve gotta look into that, It’s Dell Poweredge R410 Server: looks like this: https://i.ebayimg.com/images/g/er4AAOSwNDVfyTuN/s-l1600.jpg.

It would need to fit inbetween two heat sinks pretty snug.

I’d like to keep the cooling internal, I just have it sitting on a shelve next too other desktops k3s nodes.

The board doesn’t come with any extra on it. There is one used but it doesn’t boot without that card. Not really sure what it does. It’s a Dell Poweredge R410 Server: looks like this: https://i.ebayimg.com/images/g/er4AAOSwNDVfyTuN/s-l1600.jpg

If I could find a internal server fan smaller then 20x20mm. I’d stick one next to my 1U CPU Cooler. But for some reason I can’t find one. Needs to be smaller then 20x20 because it would sit on top of the motherboard in a closed 1U server rack frame.
