H100i RGB PRO XT, one fan always stays at 2400 rpm

so for awhile now one of the fans (I think it is an ML120 fan) has been going up to 2400rpm and stays there! sometimes for a few mins or sometimes for days before deciding to work normally and when it is like that anything I try and do like applying the zero rpm setting or a new custome setting it does not listen.

 

Here is a photoof what it looks like in iCUE:

any help is really appreciated :)

You might try swapping the two fans on the two connectors from the XT. It has two independent fan channels and you are looking to see if the problem moves to the other channel with the fan (fan problem) or stays on the current # (controller or software issue).

 

There have been some reports of stuck controllers on the Platinum/XT models, but that has always affected both fans. I would not proceed with other solutions like force flashing the firmware until the fan can be cleared of blame.

Hello! I am sorry for such a late response I have not had much time to get on pc lately :) but I did swap the connectors and it stayed on the current #

First, try the easy fix. Go to Windows Settings -> Apps and find Corsair iCUE. Click on "Modify" and follow the prompts for a repair installation. This sometimes cleans up weird behavior and will not erase your current settings or profiles.

 

That's probably not going to work. Most of the XT/Platinum users have unlocked the fan controller by forcing a firmware update. CUE settings -> XT cooler -> check for firmware update. It will say it's up to date, then choose force update. The fans will go offline and the cooler will drop out for 3-5 seconds as the software is loaded into the device. Hopefully it then restores control. However, there is always some small element of risk with a firmware update. If you would prefer, contact Corsair Support with the issue and wait for their direction.

 

In the meantime, if you have any simple 2 way PWM splitters lying around, both fans can run from the one working fan channel. It is not necessary to have independent control over both fans on the radiator.

Surprisingly the repair installation has seemed to have done the trick! it went from full rpm down to intended rpm almost straight away! still this has been an intermittent problem but it looks like it is solved for now :) thank you for assisting!
