Hello and thank you for helping. The raw readings on following config settings: compute temp1 (@ - 83.869) / 0.9528, (@ * 0.9528) +83.869 # cat /sys/devices/platform/vt1211.24576/temp1_input 99000 # cat /sys/devices/platform/vt1211.24576/temp2_input 41000 for comparison the sensor output: #sensors ... fan1: 0 RPM (min = 0 RPM, div = 2) fan2: 0 RPM (min = 0 RPM, div = 2) temp1: +15.9 C (high = +179.6 C, hyst = -88.0 C) SIO Temp: +41.0 C (high = +204.0 C, hyst = +0.0 C) cpu0_vid: +1.750 V without the compute line the hyst value seems to be ok, but the temp is pretty high. temp1: +102.0 C (high = +255.0 C, hyst = +0.0 C) Raw value: 104000 The BIOS of this device does not have an option to check temperature directly so i cannot confirm/deny the temp. Anything else i can try?
