Hi all, this is my first message to the list, so first of all: Pleased to meet everyone here. Well guys and girls, I have a little problem trying to control the cpu fan speed of a MSI K8T Neo2 v2.0 [ http://global.msi.com.tw/index.php?func=proddesc&prod_no=208&maincat_no=1 ] Really there are two problems, one related to incorrect reported voltages and the other is that it seems that pwmconfig can't match any pwm control with the cpu-fan. Here you have the sensors-detect output (I am using ubuntu 8.04 and kernel 2.6.24-19-generic, with an AMD Athlon(tm) 64 X2 Dual Core Processor 4200+) ************************************************************************************************************************** # sensors-detect revision 5016 (2007-11-11 22:20:16 +0100) 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. We can start with probing for (PCI) I2C or SMBus adapters. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-viapro' for device 0000:00:11.0: VIA Technologies VT8237 South Bridge We will now try to load each adapter module in turn. Module `i2c-viapro' already loaded. If you have undetectable or unsupported adapters, you can have them scanned by manually loading the modules before running this script. To continue, we need module `i2c-dev' to be loaded. Do you want to load `i2c-dev' now? (YES/no): Module loaded successfully. We are now going to do the I2C/SMBus adapter probings. Some chips may be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. Next adapter: SMBus Via Pro adapter at 5000 (i2c-0) Do you want to scan it? (YES/no/selectively): Client found at address 0x2f Probing for `National Semiconductor LM78'... No Probing for `National Semiconductor LM78-J'... No Probing for `National Semiconductor LM79'...

And if I try to do a pwmconfig no correlations are detected: ************************************************************************************************************************** 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 k8temp hwmon1/device is w83627thf Found the following PWM controls: hwmon1/device/pwm1 hwmon1/device/pwm2 hwmon1/device/pwm3 Giving the fans some time to reach full speed... Found the following fan sensors: hwmon1/device/fan1_input current speed: 0 ... skipping! hwmon1/device/fan2_input current speed: 5357 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 pwm control hwmon1/device/pwm1 ... hwmon1/device/fan2_input ... speed was 5357 now 5400 no correlation No correlations were detected.

Thanks for your support and best regards.
