[SOLVED] Setting AIO Pump Speed / Temp curve.

So i'm a new AIO user, just got Castle 360EX, i'm bit confused about setting pump speed. I m not able to set a stable pump speed curve for low/idle work loads.
I have 3700x and Gigabyte Aorus Elite x570, I'm using gigabyte SIV software to set fan and pump curve.
With Fans i have no issue.

Thing is when i set a temp/speed curve on pump, pump speed keeps changing every second because ryzen boosts higher / low workloads, i can't get stable pump speed at idle or low workloads, it keeps on going up and down.
while gaming/productivity tasks it settles to a stable pump speed easily, it makes me skeptical at idle and lighter workloads that changing speed so fast might affect pump itself.

I tried to get a stable pump speed curve at idle temps but barely i got in a range of delta of 200-250 rpm
Here's some data for reference:

Idle/Low work loads: 3.6 - 4.4 GHZ 44-60'C 1250 rpm -1550 rpm delta 300 rpm
Gaming /Productivity Loads : 4.0-4.3 GHZ 57-68'C 2000 rpm-2100 rpm

Whenever i reach closer to a stable pump speeds at low workloads curve ryzen starts boosting longer to make setting a failure.

Pump has min 800 rpm[30%] and max 2550 rpm[100%] pump speed,
Please suggest should i set fix pump speed like 50% or 60% or 70% or 100% etc for all time use and never bother changing it again.

Pumps should run at a constant speed all the time. On my custom loop I have it set to 85% because that is as fast as it will go without being audible. Many AIO's can be run at 100% and still be inaudible.

Your radiator fan speeds should be tied to the fluid temp, or if that is not possible then tied to the processor temp.

Thanks man, i will probably set it to 70% ~2050 RPM with fans on a cpu temp curve. I will leave it like that for eternity.

Just you know i was trying really hard this year to build a CLC myself, but you know, the thing that shall not be named got in the way and i didn't get the parts i needed so i have to settle for an AIO.
Not that it works bad or anything, but i feel like being pushed back into the crowd again ever since i dropped the task to build a CLC. :/

It's an AIO, the pump isn't that powerful to begin with, so slowing it is just diminishing your cooling potential by lowering the already (very low) flow rate.

It's not like a DDC or D5 pump which are many times more powerful.
