1. Follow Smurf' s suggestion. 2. In case of PGs I wouldn't take a risk.
In Google have more info. |

Hello zeemens I no have field pg p4, so I suggested the BIOS settings, based on the settings of other computers, although it is possible to complete the PG and there is such a tool. By configuring the chipset and the CPU is useful to look at the intel site can search the site intel. In general, the fan better change, or at least smear. Perhaps there is a problem with the sensor speed. What about soft cooler: it lowers the CPU frequency when it is reduced load. So as the method is quite suitable. Especially for the PG, where speed reduction is tolerated. And you do not have any more tools for managing fan type speedfan or other? may be a conflict of utilities? |

It seems we are 4 person club now... Club of PG-M fan problem: https://www.automation.siemens.com/tf/WW/en/Posts/39795#top So it is rather common, right? Anybody want to join us? |

Welcome again all readers! Today, following gre_m suggestion I digged out some useful information, that can be read HERE in original, but anybody not familiar with russian better use Google translator HERE. In general one guy has burned out serial port in his FPGM and he discovered that GPIO chip LPC47N252 made by SMSC is used to control serial port and fan speed. After lecture of GPIO manual that can be found HERE some new possibilities to resolve can be seen on the horizon, but I need somebody who knows more than I how to flash it and where could be theirs settings available ex. via driver. It may be that all is just speed feedback read-out as gre_m said. Looking forward to hear from you. Alltogether "we can", as Obama used to say (offtopic joke). |
Last edited by: zeemens at: 6/8/2011 10:02 AMSpeedFan can see 3 of PWM outputs, PWM0 is really controlling fan (11 levels), PWM1 does no change, PWM2 controls brightness (8 levels). Real speed values cannot be seen. PWM0 can be controlled shortly, but every 8..12 seconds (i.e.) when you see any change on PG panel) original control overrides manual setting. Meaning SpeedFan is useless in our investigation.
