Question MSI Pro z790-p WIFI : Weird settings regarding CPU-Fan/Pump-Fan / Watercoolers

Hi!
I've just updated/built my new PC, initially with a RiseMode 3-Fan Watercooler (360).
Everything was working well, and the CPU was for sure refrigerated. But for whatever reason the CPU-Fan or Pump-Fan (tried both inputs in the mobo) would always show 0 rpm/0 volts.

Went ahead and updated the Motherboard Bios to the latest version. And to my surprise, the CPU started overheating during the Update.
Tried everything I could after but there was nothing I could do, the watercooler pump wouldn't turn on, at all.

Went ahead and bought a new watercooler, a Corsair 3-Fan one.
Installed it on the CPU-Fan (that it asks to), boot the PC, to the bios I go and? 0RPM/0v.
Had to open the specific fan on the bios, and ask for it to be in "full-speed" mode.

It seems like the Bios assumes that if you're not over 50-celsius, you should just turn off the Fans, not throttle, turn off.
Which is totally suboptimal for a watercooler pump.

Okay, PC was working fine.
Installed all the MSI softwares, played some games and later on went to check their Windows Fan Utility. Guess what?
The moment I open it, the watercooler turns off.

Had to run thru it as fast as I could, find again the setting for the CPU fan, and ask it to go as fast as possible.
It seems like every time anything touches the bios fan speed controller, it defaults to "lets just turn it off, shall we?"

At this point I'm even scared of going into the Bios and it simply deciding to turn off the pump again, I do feel my previous Rise Mode pump ended up cooking.
Any recommendation, ideas?
 
Welcome to the forums, newcomer!

If it's an upgrade, what did you upgrade from, to ?

Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

So if you had a system prior, we should be seeing two sets of specs, one for before and one for after. You need to be specific with the make and model of the parts you're using.
