4790k CPU load and core temps seem to be ok!

I now see 5 fans but RPM is 0. Bellow there are now 3 PMW to adjust speed. Adjustment does not work for now.

In the advanced tab : temperature sensor diodes 1 2 and 3 are "undefined" and it is not possible to change it to thermistor or diode.

In the advanced tab with previous motherboards, there was a way to change each fan control to "manual". It is not present for now.

I attached the config files in the email.

Tested 4.50 beta 4.

IT8620E is detected but no fan speed monitored and to speed control.

If you need a file dump let me know. Thanks!

By the way, I changed to software control in the Advanced tab. ;-)

Yes, please, use SpeedFan's SEND REPORT (INFO tab) and let me know when done.
Include in its notes a reference to this issue.
Thank you.

Report Sent.

I wrote that when I try to manually change fan 0000004 speed on main window, the computer shuts down automatically.

You were right!

I spent some time this morning plugging fans @different headers:

My motherboard has 8 fan headers:

Here is my report:

CPU fan header (4pins) : not seen with Speedfan (no RPM, no speed control)
CPU opt fan header (4pins) : not seen with Speedfan (no RPM, no speed control)
SysFan1 header (4pins) : not seen with Speedfan (no RPM, no speed control)
SysFan2 header (4pins): seen as Fan1 with SpeedFan (yes for RMP and Speed control!)
SysFan3 header (4pins): seen as Fan2 with SpeedFan (yes for RMP and Speed control!)
SysFan4 header (4pins): seen as Fan3 with SpeedFan (yes for RMP and Speed control!)
SysFan5 header (3pins) : not seen with Speedfan (no RPM, no speed control)
SysFan6 header (3pins) : not seen with Speedfan (no RPM, no speed control)

Even though I can control fans on Sysfan headers 2-3-4, Speedfan cannot adjust the speed of my watercool pump. I guess this is a problem with the motherboard and PWM control limited to CPU Fan header and CPU opt header.

Hope that helps.

Thanks again for your great work.

The latest beta adds two advanced settings that, basically, prevent SpeedFan from writing to PWM 4 and PWM5, unless instructed to do so.
This will avoid computer crashes when changing PWM 4 and will let other users enable PWM 4 (it works pretty fine of several other boards).
Unless Gigabyte unveils how to program the IT8620E, I am afraid I can't do more than this.
I wrote an article about this: [^]
