Your temps look really good on the Pi 4. If it starts to concern you as the summer warms up and you are pushing the CPU a bit more with increased monitoring/control activity, I recommend the Pimoroni
Fan SHIM. It was 105 here today (southern AZ about 1/2 hr from the Mex border), so I kept my home office at about 81-82degF... My RaspberryPi4 CPU stayed right around 50degC. Like you I have the Atlas-Scientific Tentacle T3 installed.. The Pimoroni is a nice fit. Only kicks on on system boot up and when I am doing allot of interaction with the Dashboard on the local 8" LCD (you won't have that issue)
