Providing some feedback now that SCH5127 support is "mainline" in
LM_Sensors; no "force_id" option required.
I have an Acer easyStore H340 that has a SCH5127 monitoring chip inside.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. 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):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel Atom thermal sensor... Success!
(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... Yes
Found `SMSC SCH5127 Super IO' Success!
(address 0x800, driver `dme1737')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
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? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7
Module i2c-dev loaded successfully.
Next adapter: SMBus I801 adapter at 18a0 (i2c-0)
Do you want to scan it? (yes/NO/selectively):
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel Atom thermal sensor' (confidence: 9)
Driver `dme1737':
* ISA bus, address 0x800
Chip `SMSC SCH5127 Super IO' (confidence: 9)
Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes

Fan1 is a CoolerMaster Excalibur R4-EXBB-20PK-R0 120x120x25 mm fan. It has
a speed range of 600 ~ 2000 RPM +- 10 percent per vendor. It does get loud
at full speed but it also moves air: 26.4 ~ 85.6 CFM +- 10 percent per
vendor.
The system has 2 fan headers, both are 4-pin. I have only tested "fan1"
(Sensors label: Side Fan) ("pwmconfig" detected: hwmon1/device/pwm1) using
"pwmconfig":
[root@anas-01 ~]# pwmconfig
# pwmconfig revision 5857 (2010-08-22)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. 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/device is coretemp
hwmon1/device is sch5127
Found the following PWM controls:
hwmon1/device/pwm1 <- local label "Side Fan"
hwmon1/device/pwm2 <- local label "MCH Fan"
hwmon1/device/pwm3 <- no header on motherboard
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon1/device/fan1_input current speed: 2253 RPM
hwmon1/device/fan2_input current speed: 5147 RPM
hwmon1/device/fan3_input current speed: 0 ... skipping!
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 is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.

Experiences so far:
(1) "fancontrol" script does work, but I would like it to run as a
"background" process or even as a daemon. I'm not a programmer so I don't
know if this is even possible or how to do it.
(2) Fan speed on "Fan1" does go up and down with system temperatures.
