Built my OPNsense on this N150 device (US amazon item B0F4WXKZRB bare bones)
16GB ram, 256GB NVMe drive
A little tunables tuning and it does excellent job for home 1.3Gb copper service. Maybe some day I get docsis4, then I switch the fw WAN over to a 10G gbic.
Temps stay between 46-50C.
Odd though, the bottom cover has tapped holes (possibly for mounting, not sure), but I plan to install another micro fan there.
So far so good.
Here's a set of tuning which yields decent performance with a balance between idle state and max processing (heat). Most of these tunables were not in the system, but still try and find each before adding it.
# this removes some time consuming resources from entropy for random
kern.random.harvest.mask: 65887
# lower means leans towards higher performance. setting 0 seems to peg cpu at max freq
# if you want to unbalance them for power savings, set 0 around 10 and the others at 50 or 75, etc
dev.hwpstate_intel.0.epp = 25
dev.hwpstate_intel.1.epp = 25
dev.hwpstate_intel.2.epp = 25
dev.hwpstate_intel.3.epp = 25
# leave 0 alone at C1 (default C1, so no need to set it)
dev.cpu.1.cx_lowest = C2
dev.cpu.2.cx_lowest = C2
dev.cpu.3.cx_lowest = C2
# place this KLM load in about middle of the '/usr/local/etc/rc' script

Thanks Brandywine, I'm interested to try these as I'm running an N150 box myself but could you please provide a little more context on what they do?
Thank you!
