That's iStat menu, a paid software.sorry guys for the time travel. My baby, my 5,1 has started running with fans at full speed from boot, AHT say an SMC issue. SMC flasher doesn't fix it. the image above shows running temps across the logic board, but no where does it say what the app is. I have no idea if it's a wire, or a sensor... can someone let me know what the app is/was so I can probe the temps and see if I can fix it..? thank you..
If you just need the temperature readings, you may simply use MacsFanControl.
