notebook lenovo g50-80 fan sensor missing

[zeratul75]

hello

just bught a notebook, lenovo g50-80.

every sensor works fine, but aida misses fan speed sensor. Is there a way to display it?

The system fan (the notebook has only one fan)  is connected by 3 wires, so it should supports monitoring as far as i know.

thanks a lot

Do you have any tools, made by Lenovo or a 3rd party, that could display the fan RPM? Or maybe you can see that reading in the BIOS Setup? Just because the fan has got 3 wires, it doesn't mean the RPM is really monitored by the onboard Embedded Controller chip.

Nope. I cant see anything about it in BIOS but my BIOS doesnt show CPU temperature neither, Like Aida does....

The same regarding any lenovo preinstalled software.....none gives me fan speed...I though Aida could do this job....

AIDA64 can do whatever the underlying hardware can do If the notebook PC you've got is capable of measuring fan RPM, and also capable of providing the readout to 3rd party applications like AIDA64, then -- at least in theory -- AIDA64 can indeed show that value. However, when the hardware itself is not prepared to measure fan RPM, then no software will be able to show such value to you, including AIDA64.

By that I'm not saying that your notebook is not capable of measuring fan RPM, but instead that there's no proof so far that it could. We can try digging deeper if you can provide a few debug dumps about your sensor devices:

Please right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> ISA Sensor Dump. Copy-paste the full results into this topic, or attach it as a TXT file to your post. You may have to enable the status bar in AIDA64 / main menu / View first.

Then also right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> SMBus Dump (Full). Copy-paste the full results into this topic, or attach it as a TXT file to your post.

Finally, right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> Embedded Controller Dump. Copy-paste the full results into this topic, or attach it as a TXT file to your post.

Thank you.

thanks, now I undestand the situation.

If you want to try I attach sensors debug, as requested.

thanks

Thank you for the data. We've checked those, but I'm afraid we cannot find the RPM there We've also checked the ACPI BIOS for your system, but it also hasn't got any traces of a fan RPM reading mechanism. It still doesn't mean your notebook is incapable of measuring fan RPM, but at this point only Lenovo could provide information on that.

hi, thanks anyway for your efforts, i really appreciated.

unfortunately there is not any software provided by lenovo for hardware monitoring....

anyway, thanks again, aida is very usefull for many other monitoring tasks
