Oh wow, I didn't know that. I will try it tomorrow, thank you! The noise at around 2000 RPM with the Pro XT is still very bad in my opinion. I can easily hear the humming/whine you talked about. (Even from a few meters away, and I can even hear it with headphones on :/)The non XT with the Asetek pump is already a lot better at 2000 rpm, but still audible (less whiny, sounds more like a case fan at around 700 rpm) It starts getting significantly better at around 1700 RPM on the Asetek pump though.

I'd return it. However if you're fine with it, just measure the delta between RGB on and off and adapt your fan curve accordingly. As c-attack already pointed out, this seems to be related to an unfortunate placement of the temperature sensor and not an actual increase of temperature of the liquid.

Hello everyone, for everyone who has the same problem, I found a great workaround. (Only applies if you can still return your CoolIT pump product and get a model shown below ;) ) 1. Get a H100i / H115i / H150i RGB PRO (non XT!) with Asetek Gen 6 Pump 2. Install Argus Monitor and uninstall iCue: https://www.argusmonitor.com/en/index.php 3. Configure Pump and Fan Curve depending on your needs (Pump can be controlled very precisely, the sweetspot was 50% (1740 RPM) for me. The only restriction I have is RGB now, since Argus Monitor and iCue can not run at the same time - so the pump RGB will run in demo mode all the time. However my PC works silently now and I'm happy. I still don't understand why this is not possible with iCue and there is no profile for around 1500-1700 RPM. It turns out this is the sweetspot in terms of performance and quietness. (At least for me) BTW: I also tried the same with the H100i RGB PRO XT. It really seems like the pump speed is hardware limited to three discrete values here. I was only able to chose between three different RPM speeds starting at around ~ 2000 RPM. Going lower was not possible! Still 2000 RPM is way too noisy.

Swapped the H100i Pro RGB XT for the H100i Pro RGB today and finally I have a silent pump on "Quiet". 1000 RPM instead of around 2000 RPM. You can hear "balanced" on the H100i Pro but it's significantly less pump whine. Now I just need to find a way to get the pump from Quiet to Balanced depending on liquid temp. It seems like support for this AIO is coming soon here: https://github.com/liquidctl/liquidctl With this I will probably implement a custom pump curve. (< 37°C Quiet / >= 37°C Balanced) I really wonder why this can't be set with the iCue software....

Curious as well. Are you using AM4 socket? I have screwed them in with my hands and didn't use the screwdriver in fear of bending the screws too far.

Hey, after starting my computer today, I noticed the pump got significantly quieter in "quiet" mode - Definitely no placebo, as I'm very sensitive in that regard. You can still hear it but I'd say it's about half as loud. Maybe it just needs some time? Because of this I will give it another 2-3 days until I replace the unit with the H100i Pro. I have mounted the unit on the top of the case btw, so there shouldn't be any problems with trapped air and/or increased pump strain. EDIT: Nevermind, after restarting the PC the pump is noisy again. Can't really explain it.

Hi everyone, just a quick question: Does the H100i Pro RGB (pump) get as bright as the H100i Pro RGB XT? I've seen some review and I get the impression, that the Pro XT is much brighter.

Thank you. Just ordered the H100i Pro to replace the Pro XT.

I have the same problem with a new H100i RGB XT. I think I will return it. I'm now looking for a H100i RGB without XT. I've read they are quieter?
