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.
There are centrifugal fans that are quite flat but they intake airflow from a different axis they exhaust it from. Could still work
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.
Have you had a look at PCI exhaust fans and cable ties as cheaper version of this https://akasa.co.uk/update.php?tpl=product/product.detail.tpl&model=AK-CC7401BP01
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
Do you mean the card with the SODIMM next to the CPU? that is a raid card, and it looks like it is responsible for the front drive bays.
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?
You can use a larger fan and a shroud to redirect the air flow, similar to how laptops are cooled.
I’d like to keep the cooling internal, I just have it sitting on a shelve next too other desktops k3s nodes.
I just meant you can have an internal fan that’s larger than your heatsink, and a shroud to direct the airflow to it. It requires less vertical space, but more horizontal space.
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.
