Note that many motherboards do not have pwm circuitry installed, even if your sensor chip supports pwm. We will attempt to briefly stop each fan using the pwm controls. The program will attempt to restore each fan to full speed after testing. However, it is ** very important ** that you physically verify that the fans have been to full speed after the program has completed. Found the following devices: hwmon0 is dell_smm hwmon1 is coretemp hwmon2 is amdgpu Found the following PWM controls: hwmon0/pwm1 current value: 255 hwmon0/pwm2 current value: 255 hwmon2/pwm1 current value: 22 Giving the fans some time to reach full speed... Found the following fan sensors: hwmon0/fan1_input current speed: 3432 RPM hwmon0/fan2_input current speed: 2202 RPM cat: hwmon2/fan1_input: Invalid argument hwmon2/fan1_input current speed: RPM Warning!!! This program will stop your fans, one at a time, for approximately 5 seconds each!!! This may cause your processor temperature to rise!!! If you do not want to do this hit control-C now!!! Hit return to continue: Testing pwm control hwmon0/pwm1 ... cat: hwmon2/fan1_input: Invalid argument hwmon0/fan1_input ... speed was 3432 now 1492 It appears that fan hwmon0/fan1_input is controlled by pwm hwmon0/pwm1 Would you like to generate a detailed correlation (y)?

It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. Some south bridges, CPUs or memory controllers contain embedded sensors. Do you want to scan for them? This is totally safe. (YES/no): Module cpuid loaded successfully. Silicon Integrated Systems SIS5595... No VIA VT82C686 Integrated Sensors...

(address 0xa00, driver `f71882fg') Some systems (mainly servers) implement IPMI, a set of common interfaces through which system health data may be retrieved, amongst other things. We first try to get the information from SMBIOS. If we don't find it there, we have to read from arbitrary I/O ports to probe for such interfaces. This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): Probing for `IPMI BMC KCS' at 0xca0... No Probing for `IPMI BMC SMIC' at 0xca8... No Some hardware monitoring chips are accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now?
