Linux check temperature7/27/2023 Run lm_sensors repeatedly until you have a rough idea of which core is the one heating up.ĭo this repeatedly, once for each core, until you are sure. It should execute on one of the cores (you can see which one on htop, the core will run at 100%). Write an infinite loop in your favourite language, then run the program. (You can change this by pressing F2 to go into setup). Make sure that it has an activity bar for each core, i.e. One method of checking which core is having which temperature is to bake one of your cores at a time (eg using an infinite loop), and then see which one is being baked. If you find that the database is wrong, make sure to tell the lm_sensors devs! I had to modify some of the variables in the database for my motherboard. Yes, I second progandy's recommendation that you have a look in the database. The core temps should be significantly warmer, but this chip does not include those sensors. Of course this is the CPU temp and not core temps. The ambient temperature where my box is is normally between 14-17C at this time of year.Īt full load the system can approach the high AMD recommends, but usually the ambient temperature inside needs to be significantly higher than what I posted above. When at full load the sensor peaks slightly under what AMD recommends as overheating, so it seems that it scales well. For a processor drawing a dozen Watts or so, these are the sorts of thermodynamic numbers I would expect.īoth BIOS and one of the lm_sensors temperature readings that I believe is for the CPU both report that my AMD 1090T idles at around 33C with air cooling. The heat sink is not instrumented, but the heatsink to processor case interface is probably on the order of 30C. That is a thirty degree rise in junction temperature over ambient. My laptop is in a 18C room right now, the lid is closed, I am at $DAYJOB, it is doing very little. There is no possible way that a core is running at 20C if the computer is inside any kind of habitable space.
