IT87 +2 fans

Description

The new and patched IT87 module (patch received from Jean) supports 5 fans. Sofare, I am not able to see any additional fan input for the IT8716F, even after using trunk 4765. Is the code tested or does my board has an older IT8716F? If the latter, how does the ASUS M2NPV-VM board displays four fans in the BIOS? How can I determine the version number of the IT8716F?

KR, Frans de Boer.

First thing to check is whether the driver itself finds the extra fans. The pins for fan4 and fan5 are shared with other functions so they may not be used for fan speed monitoring on your system. Load the it87 driver and look in /sys/class/hwmon/hwmon0/device. You should see many fan* files. Do you see fan4_* and/or fan5_* fans?

How many fan headers does your motherboard have? How many fan speeds reported in the BIOS?

The code was tested in ticket #2227 so I am confident that it somewhat works.

It's hwmon1 in my case, and it only reports 3 fans. So it seems that the other ports are not used. The BIOS, however, does report 4 fans. It's ASUS, so getting info is not very likely. I will check the connection of fan4 and if found that it is connected to either fan4/5 input, the port must be enabled. I have the specs, so I will try this myself. If it is other hardware? maybe I can find it out, maybe not.

Thanks, frans.

It is possible that the 4th fan is connected to a different chip. We have seen recent Asus boards where this was the case. Please run a recent version of sensors-detect (2.10.4 or SVN) on your machine and attach the complete output.
