Fan Speed Seems Really High w/Commander Pro

I recently installed the Commander Pro to house my 6 fans. 3 of which are attached to my H150i, which is attached to my 5800x. According to iCue, even while set to quiet, the fan speeds seem to be really high at around 1300-1400RPM. The photo link is when I'm just typing this thread out. Is that normal? They sound rather loud. When I had my 3600 installed, it didn't sound loud unless I was gaming. I didn't have the commander installed at that time.

The default fan profiles are utter junk unfortunately. You should create your own fan curve :

On top of the list with Quiet/balanced/extreme, there's a little + icon.

Hit that and create your own fan curve. You can also select which temperature sensor will be used for controlling the fans.

CPU temp will constantly make the fans ramp up and down, so you could instead use your GPU temp, since it's the one component that dumps the most heat in the case.

Do you have any recommendations for a curve? I'll likely google it.

 

Edit: Set the source to my 5800x and it gave a default curve for it

The default presets on the Commander do not mean the same thing as the Quiet/Balanced/Extreme on the H150i. It's a relative term, like low, medium, high and in this case with a different control variable. As mentioned above, everyone should make their own curve immediately. The 1400 rpm thing is what happens for everyone sitting there on CPU temp.

 

If you have a H150i, the quick fix is to create the custom curve, then select one of the three shape tools in the upper right hand corner of the graph. Those correspond to the Quiet/Balanced/Extreme curves for the AIO. Make sure to change the sensor choice to "H150i Temp" (coolant temperature). This will keep the fans in balance.

 

You also can use specific control variables as needed. GPU temp is an easy one most people understand and may have a direct relation to rear exhaust or front intake speeds.

 

The only negatives on the two choices above it they require the software to be running in order to get that data from the origin source. If you spend a lot of time without CUE running, you will want to make use of the temp probes that come with it. That is the native source for the controller and works all the time, software or not. For the AIO temp, you put one on the exhaust side of the radiator. Exhaust air temp will mirror coolant temp within a 0-2C stable offset. To replace GPU temp control, putting one at the rear exhaust is going to be the best place and you can use a contrasting data point on front intake air. The trick here is you have to learn your unique temp range. This will change with GPU load, other case heat, the exact position of the sensor, and of course local room temp. No one can give you an exact range and moving the sensor over 3cm could change the temps by a fair amount in some circumstances. You have to figure this one out as you go.

5800x are a hot running chip. they're totally safe to run hot, but those profiles are made for older intel chips that read cooler - so its going to think you're overheating and ramp those fans right up even at idle.

 

 

Either set a manual curve, or a static fan speed.
