Hi, I bought a Dell Optiplex 7000 earlier this year and have been slowly growing my homelab but my office's temperature has gone up about 6 to 8 degrees. I expected it to rise, but not as much. I've put fans on my 10GbE switches, mini PCs, and got everything cooled down by at least 10 degrees.
However, this Dell Optiplex is the remaining piece and it's a generating massive heat as I have two Intel X550-T2 10GbE network cards. When I used the temperature laser it's surface is about 120 degrees, whereas the CPU area NVMe's are around 95. Other areas are high 80s.
Overall, to give you an idea, I put a thermostat in the corner where that PC is and one in the opposite corner and that corner was 85 degrees whereas the opposite corner was 74!
I'm not much of a hardware guy, and to be honest prior to this "server" I've had mostly laptops. However, I noticed that there isn't any fan at the front of the server. There is a little black box, but I have no idea what that does. I was originally thinking of putting a Noctua fan in there (after making way by organizing the cords a bit; it's all a WIP). But I was curious if I could do something for the NICs... they already have a small heatsink on there, but I don't know if I could just place other heatsinks on there or if I should get some tiny fan (like 40mm) and direct air towards them?
Any ideas would be greatly appreciated.
