shouldn't you just run a moisture remover and just direct vent the servers?
That's in the plans. Right now they're just open to the air, so the heat pretty much dissipates away. The server room sensor is actually on the ceiling too so the temp is a bit biased towards the high side. I get cpus running at like 15 sometimes. :awe: Really need to better climate control that room though. I'd probably have it set to recirc till it hits like 20c then it would start to exchange air.
It gets dry in winter so I actually need to run a humidifier, but when it's this cold I turn it off or the windows get frost. Not sure what I'll do for humidity in server room once I setup hvac though, because the air will be going through a HRV to remove battery hydrogen. I should have put the batteries in the crawlspace and have those vented separately, never really considered humidity control, only temp. The HRV will recover the heat before the air goes outside.
