H100i Elite fan speed issues

I have Asus z490-i mother board and above cpu fan, changed it from NZXT 240 MM to this and to be honest i dont know...

 

Just so i understand this new generation of CPU fans, when i plugged in the cooler direcly to mother board CPU jack i only saw single cable, i think what that will do is provide RPM of the Pump to the mother board.

 

That I think causes couple issues here, my mother cant control the fan speeds unless Windows is up and running logged in and iCUE running and when windows is locked or not on yet, it sounds like Jet, i can hear it downstairs until CPU temp drop below 35 C i think.

 

when the iC app is on i can select ZERO rpm mode and they stay quiet, is there is any other way to make this work without relaying on the app? Like i said i finish gaming lock my computer the iCUO app looses connection i guess and fans take off like jets.

 

Any help is appreciated

The Commander Core is your fan controller for anything connected to the PWM side of the device and the motherboard will have no input on those. I have not been able to do a lot of default behavior testing with it yet, but a quick fix and ultimately what most users are going to want anyway is to get off the three presets and use a custom curve.

 

Performance Tab + to create a new curve. Graph will appear below. Make sure sensor is set to H100i Elite Temp. This is the coolant temperature, the correct control variable, and the native sensor inside the device.

 

Then click on one of the three shape tools in the upper right corner of the graph. These correspond to the three presets and were designed for coolant temp. The difference is now you can see the data points and alter them as needed. Not everyone has a 20C baseline temperature. Since this is the native sensor for the device, the fans should follow the curve with or without the software running. This would also work from the one temp probe register on the side of the Commander Core.

 

Don't forget to apply the fan curve to the fans on the Commander Core. Select your new fan profile and it will highlight yellow. Then click all the fans on the right you want to run those data points. They will ring yellow to show they are now part of that group.

Thank you bud

 

Can you take a pic of your power curve, I keep my fans off until 40C 41C they go to 25% at 50C they are at 100%

 

This fans really sound like jet, I saw someone said that fans from h100i are worse than nzxt cheaper model, something about air flow, and the fans that corsair picked for this line of cpu cooler

Your curve sounds fine. There is no Temp X =Fan Speed Y requirement to this stuff and it all based on your ambient case temp. A curve that is perfect for a typical Winter's day will be intolerable at idle during Summer. You can set them as low as you like at the H100i Temp you normally see at idle. Typically this is +4-7C above your room temp once the PC is warmed up. You need at least 1000 rpm to do much cooling with a 240mm. Beyond that it is noise tolerance. Most people do not need to run anywhere close to 2000 rpm. +1C coolant temp =+1C CPU temp (and in reverse for cooling), so there is no need to blast the fans for a 1-2C reduction. When unsure, go with noise. You can't overheat a liquid cooling system with deliberately turning off the fans or poisoning the environment another way.

 

The fans on the Elite coolers are a unique 8 LED version of the ML-Pro. This is a good radiator. However, no fan is pleasing is at 2000 rpm plus. Stay out of that zone. You don't need it unless you are brushing up against some critical CPU temperature threshold.
