Question Best Curve for AIO Pump Arctic Liquid Freezer 3 360?

Hey everyone,

I’m wondering whether it’s better to run my AIO pump at a constant speed (100%) or if I can set a fan curve to make it quieter when the system isn’t under load.

I asked GPT for a suggested pump curve, and this is what I got:

• <40°C → 30%
• 50°C → 50%
• 60°C → 75%
• >70°C → 100%

I’ve already set this curve in the BIOS—does this seem fine, or should I run the pump at a constant speed instead?

I also applied a similar fan curve to my VRM fan. Is that okay, or should I adjust it differently?

One thing I’ve noticed: when the fans are running quietly, I can hear a slight whizzing sound from the pump. Is this normal, or could it indicate an issue? Are there any ways to reduce this noise? Also every time I start up the PC, the Pump has a louder whizzing noise which immediatly goes quiet.

Thanks in advance for any advice!

I asked GPT

Don't do that.

But, moving on....
What temps are you currently seeing?

In AIO systems, the pump should be run at 100%.
The fans, variable.

So multi core cinebench r23 was peak temperature 85 degrees celsius with the curve I set in bios for pump

Gaming : black ops 6 (60-70 degrees averaging)
Hogwarts legacy (55 degrees average)

Yeah but at 100 % the pump is too noisy for me, so isn't there another way?

also what should i set my exhaust fans and VRM fan too? No idea, and theres no instructions

I'm looking for advice on optimizing my Arctic Liquid Freezer 3 360mm AIO cooler settings in BIOS or fan control. Currently, I have the pump set to a constant 60% to reduce noise, but I'm unsure if this is optimal for performance. Should the pump always run at 100%? At full speed, it's quite noisy, but at 60%, it's much quieter. Also, I'm planning to set a custom curve for the VRM fans. Any thoughts or suggestions?

There's no use to fuss much with speed curves, control of fans, even PWM is quite coarse, to start with there's +/-10% speed variation between 2 of them and accuracy is at least +/- 200-300RPM.
So best way is to set starting point which is about 600RPM at idle and set straight line to about 90c to maximum RPM.
That's for radiator fans but pump speed is more important because CPU temperature fluctuates fast and it takes some time (few seconds) for liquid to reach radiator and get cooled in it, by that time CPU can overheat. That's why it's always recommended to keep pump running at high or even full speed so it can start removing heat from CPU via hot plate right away.

would constant 65 Percent for pump be okay because otherwise its clearly noisy?
And what about the VRM Fan Curve?

You'll have to try pump yourself but VRM fan is on same motor as pump.
