I have the ec_sys module in my kernel. I can load it. I just did not know how to get anything out of it.

``` # hexdump -C /sys/kernel/debug/ec/ec0/io 00000000 d8 26 1f 1c 28 07 27 00 00 00 00 00 00 00 00 00 |.&..(.'.........| 00000010 00 00 00 00 00 00...

Yes I have a Water Out sensor connected and displaying the correct temp. No Water In sensor connected.

I re-ran the command and got a different dump output. ``` # hexdump -C /sys/kernel/debug/ec/ec0/io 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00...

Haha LOL. Well it might all be obvious to you, but to me it is all gobblygook. I don't know how to read the registers and know what they represent....

I'm only using the CPU_FAN, AIO_PUMP and FAN4 headers on the board currently. Along with the WATER OUT sensor. FAN4 is connected to the pump speed output of the D5...

I can convert hex to decimal. But I have to know what the rows and columns in the output represent. This is the mysterious part. No, none of the fans...

I don't use any PWM components. Only full speed for every component as all my hosts run flat out 24/7 crunching science. Temps have be limited to the environment.

No, a 3 pin fan is not PWM controllable. Ground,+12V power and sense wire. The only way to control speed is to reduce the voltage supplied to the fan. +12V...

In the UEFI, to run full-speed you either have to disable fan control or in this Zen 4 UEFI, the setting is just 'Full-Speed'
