I’m looking for advice on cooling/temp monitoring for a Pfsense router. I picked up a cheap refurb Dell 7020 SFF i3 to use as a PFsense box. I put a quad i340 gigabit adapter in one PCIe slot and a Mellanox MCX-311a in the other for potential 10gb down the road. I’m a bit worried about airflow & heat, since I’m planning on hiding this up in a closet in my house.
Are there probe thermometers that can attach via USB for temperature monitoring? If I have to, I could tax the network cards, pop the case, and use an infrared thermometer, but that’s a labor-intensive solution.
I appreciate any thoughts/advice.
