I have my office and rack in the basement where I work out of during the week. In the early spring and late fall when there isn't much cooling it would get rather warm to be comfortable (80F-82F).

A few weeks ago I realized that I have a cold air return duct in the ceiling so I cut an 8"x10" hole in it and left the furnace fan on 24/7 hoping that would help...it didn't really.

Last week I decided to hang an ~8" fan 3" below the hole I cut into the cold air return to see what would happen if I forced air into the duct...it didn't do much.

Last Thursday I remembered something from my volunteer firefighter days about how to set up a fan to ventilate a room through a window/door and how it was important to have the wind cover the entire opening. This led me to put a 12" fan in place of the 8" fan at 9PM.

Fast forward about an hour and my office was now 76F. The next morning it was 72F and it has stayed at 72F-73F ever since then.

The side benefit is that I'm able to provide a bunch of supplemental heat to the upstairs meaning that rather than my heat pump running 16hr+ per day with the electric strips kicking on periodically overnight during the <15F weather we've been having the heat pump has been running for 8hrs per day and the electric backup strips haven't needed to kick on at all.

​

I'm curious how it works for cooling next summer when I won't be able to run the furnace fan 24/7 since that'd just dump humidity back into the house so we'll see how that goes.

I'm still pretty happy with the results at the moment.

I'm running 2 Proxmox nodes in an HA Cluster with dual E5-2697A V4's and while it works great it's making my office rather warm.

The 9124 isn't cheap, however, it has a 200W TDP and has a higher benchmark with just 1 of them compared to my dual Xeon setup. It's $1150 though which is kind of sucky, however, it should kick out much less heat I'd think?

Is anyone using this CPU or the other 2 I listed below? They are $1600-$2000 though.

ETA: The Supermicro H13SSL-NT is the same as the H13SSL-N except that it has 10Gbe, however, it's $120 more expensive. I don't need it as I use SFP+ with fiber everywhere at the moment.

I've been dreading doing it, however, it wasn't too bad. I had 4 LXC's to convert to VM's in total.

The biggest difference is that the LXC I had which hosted CodeProject.AI for my Blue Iris server went from using 120GB down to 19GB to for the same containers. I'm guessing it's due to being able to change from using vfs in the LXC to overlay2 in the VM.

Having docker-compose yml files to recreate all containers on the VM helped a TON as well as using rsync to move everything over to the new VM that the containers needed.

Has anyone else made the move?

I got the kick in the pants to do it after trying to restore the 120GB LXC from PBS, giving up after 2 hours, and restoring it in totality from a standard Proxmox backup instead which only took 15 minutes.
