Hello and happy new year to all! First of all, I'm using 2.6.20-rc3 with the svn version of lm-sensors and the patches http://lists.lm-sensors.org/pipermail/lm-sensors/2006-December/018420.html http://lists.lm-sensors.org/pipermail/lm-sensors/2006-October/018128.html (coretemp and *_msr visibility). The kernel was built with standard Debian options using gcc 4.1. Now my problem is that I'm trying to set up lm-sensors on a machine using Tyan Tempest i5000XT motherboard (also known as S2696, please see http://www.tyan.com/products/html/tempesti5000xt.html). It has, according both to the specifications and sensors-detect output, not one but 2 hardware monitoring chips: W83627EHG and ADT7470: # sensors-detect ... Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `to-be-written' (should be inserted): Detects correctly: * Bus `SMBus I801 adapter at 18c0' Busdriver `i2c-i801', I2C address 0x2e Chip `Analog Devices ADT7470' (confidence: 5) * Chip `Intel AMB FB-DIMM thermal sensor' (confidence: 9) Driver `w83627ehf' (should be inserted): Detects correctly: * ISA bus, address 0xc00 Chip `Winbond W83627EHF/EHG Super IO Sensors' (confidence: 9) Driver `coretemp' (should be inserted): Detects correctly: * Chip `Intel Core family thermal sensor' (confidence: 9) Unfortunately it looks that the case fans -- which create the deafening noise making the machine all but unusable currently -- are connected to ADT7470 and not the W83627EHG because # sensors coretemp-isa-0000 Adapter: ISA adapter temp1: +29 C (high = +85 C) coretemp-isa-0001 Adapter: ISA adapter temp1: +33 C (high = +85 C) coretemp-isa-0002 Adapter: ISA adapter temp1: +32 C (high = +85 C) coretemp-isa-0003 Adapter: ISA adapter temp1: +33 C (high = +85 C) w83627ehf-isa-0c00 Adapter: ISA adapter VCore: +1.21 V (min = +0.00 V, max = +1.74 V) in1: +8.29 V (min = +13.46 V, max = +13.36 V) ALARM AVCC: +3.31 V (min = +3.87 V, max = +4.02 V) ALARM 3VCC: +3.33 V (min = +2.91 V, max = +2.93 V) ALARM in4: +1.26 V (min = +2.00 V, max = +1.87 V) ALARM in5: +1.60 V (min = +1.86 V, max = +1.50 V) ALARM in6: +5.02 V (min = +3.23 V, max = +4.56 V) ALARM VSB: +3.28 V (min = +0.69 V, max = +3.06 V) ALARM VBAT: +1.52 V (min = +2.16 V, max = +2.48 V) ALARM in9: +1.09 V (min = +0.78 V, max = +1.52 V) Case Fan: 0 RPM (min = 3515 RPM, div = 128) ALARM CPU Fan: 2083 RPM (min = 5921 RPM, div = 4) ALARM Aux Fan: 0 RPM (min = 811 RPM, div = 128) ALARM fan5: 0 RPM (min = 168750 RPM, div = 8) ALARM Sys Temp: +39 C (high = -65 C, hyst = -75 C) ALARM CPU Temp: +34.5 C (high = +80.0 C, hyst = +75.0 C) AUX Temp: +33.5 C (high = +80.0 C, hyst = +75.0 C) (notice the zeros for the case and aux fans). Unsurprisingly, running pwmconfig or writing directly to the files mentioned in Documentation/ hwmon/w83627ehf doesn't affect these fans. More surprisingly, it doesn't seem to affect the CPU fan(s) neither but I don't care much about it as they're not very noisy anyhow. I care a lot about the 2 case fans though so I'd just like to ask if I am doing something wrong with w83627ehf or is it just that my guess that these fans are handled by ADT7470 is correct? And, in the latter case, is there any hope for ADT7470 support? I'd be very willing to help as much as I can but unfortunately I don't really know much about this stuff so I'm afraid I have no chance without some/lots of guidance. Of course, I'd be also happy to provide any additional information that might help. Thanks in advance! VZ
