I'm still using this cooler to this day, no problems besides still not being able to control the fan speeds. I've tried all the advice offered up until this point. If anyone has anything new to contribute, I would be grateful; thank you. P.S. It could just be a manufacturer defect, but I don't plan on RMAing at this point.

Doesn't matter what curve or preset I use, my fans seem to be locked at their current RPM. I did unhook the splitter cables for the fans and reconnected them in a hope to reset them. Didn't change anything. The fans are detected in the BIOS, although it isn't able to grab the speed of the fans.

The fans did not change with the experiment. This motherboard only has 2 headers, both of which are being used, so that's not an option.

It changed nothing. I realized while testing some stuff in BIOS, that while the fans are detected, the RPM is N/A for both fans. On my motherboard there are only two fan headers: CPU_FAN1 and CHA_FAN2/WP. My pump is connected the the later, while the 1 chassis fan I have is connected to the CPU_FAN1. I am going to switch these around and see if I have any change. I will report back.

Here is an image of the fixed mode: Here is zero RPM mode: 1800 RPM: The only other software I use for my computer that monitors data is MSI Afterburner and RivaTunerStatisticsServer. Also, although this unit is not brand new, it's not even a year old yet; and yes, the fans have never changed speeds from day one. I always assumed it was a software issue until I tried adjusting the speeds in the BIOS a few days ago. My computer's temperatures stay pretty good overall, and while I don't know much about liquid cooling and how it works, I can only assume that the fans would help to reduce load on the pump.

The pump itself is plugged into the motherboard fan header, while the two fans connected to the pump are connected via the splitters, so they are not connected directly to the board. @jamie1073 I'm basing if off the CPU package temperature. Quiet: Extreme: As you can see the fan speeds stay relatively the same.

My apologies, I have filled out the information of my specs in my profile. The temperature of the H100i is 32 Celsius idle. I have tried a curve with fixed %, fixed RPM, and custom curve. None affect the speed of the fans. Also, for some reason it doesn't allow me to set a custom curve to my pump, although I am able to apply any of the default curves (quiet, balanced, extreme).

To start off, I should say that I use iCUE to monitor and control the H100i Pro; however, it seems that I can only change the speed for the pump itself. If I try and change the speed/profile for the fans, the RPM remains the same. I should also note that one of the fan seems to idle slightly lower than the other (~1150RPM vs. ~1200RPM), although I suspect this is due to the design of my case and I don't think there is really an issue here. For reference, the speed I just previously mentioned is where my fans idle. They never go any higher or lower, regardless of system load. The last thing I can think to add at the moment is that I have tried changing the speeds/settings in my BIOS (ASRock Phantom Gaming 4-CB) with the same results as iCUE. I am able to change the pump speed; yet the fans, while detected, will not change speeds no matter what.
