Was only solved by replacing the pump(entire cooler). We had to do an advanced RMA.

Sorry... if I understood correctly. Your case has a standard fan hub inside. Your H100 didn't bring a commander core? Older version ? From the list below, which product is yours ? https://www.corsair.com/br/en/Categories/Products/Liquid-Cooling/c/Cor_Products_Cooling

Very similar issue to mine, but I am on a Capellix. Enjoy the read...

New H170i Arrived (Advanced RMA). Good news and bad news: Bad: - New installation method for AM4. Doesn't sit very well with the Gigabyte X570 Aorus Pro - Temperatures are 5-7 degrees celsius higher - Misc bag didn't include the fully needed thumbscrews, so had to "snatch" two from my previous H170i Good: - Pump appearing and can be controlled from iCue. - This mounting bracket is much easier to work with as it uses the preexisting holes/backplate in the motherboard instead of the method that resembled the Socket A coolers (Board stabbers... if you know.. you know.. 🙂 ) Potential work that I might do over the weekend: - Use the commander core that came with this Cooler instead of the one that Corsair sent me before. - Buy new decent Thermal Paste and apply it again, as I am using an older one by thermal grizzly. - Fully Reinstall iCUE. And a massive shout out to Mathew B. from Corsair CS as he was an absolute hero in every single step!

New update: - New Commander Core arrived - Clean uninstall of iCUE - Clean install of iCUE Same results. Waiting on support to decide on next actions. I am starting to suspect a dead pump... if that is the case, looks like I'll have to use my old NZXT x63 until I get the H170i RMAed.

Not a bother, just trying to help! Also.. I forgot to add this earlier. Was posting from the phone and forgot to add this image. There you will see the 3-Pin fans and the 4 Pin fans 3 Pin are usually controlled by voltage 4 Pin are PWM (Pulse With Modulation) The Commander Core XT is a PWM Fan Controller and a RGB hub, so no matter what trick you can do, you'll never be able to control the speed of 3-Pin Fans, only 4 Pin. Also.. I don't know if the rules allow this, but if they don't.. lets hope the mods edit the post instead of banning me... I had this site in my favourites from when I was trying to understand what I could do with some 3-pin leftover fans I had lying around https://www.futurescope.co/are-3-pin-fans-controllable/ Hope it helps in any way!

People have been having and detecting issues with firmware updates on Commanders. I don't know if that would be a wise choice.

Regardez ici..

Did you do a firmware upgrade to the Commander Core?

Pardon, mon français c'est pas fantastique.. Il pourrait y avoir un problème avec le Commander Core. J'ai un situation similaire, ils vont m'envoyer un nouveau Commander Core.

Aparentemente há uns problemas com o iCUE / Firmware. Não sei se há suporte em português... mas se procurares no reddit e aqui no forum, vais ver que há problemas semelhantes.

Based on what most are reporting and experiencing.. that would be my guess.

You are having similar behaviours to what many people are reporting. It seems that an iCUE update/firmware upgrade has damaged Commander Cores. Corsair will be sending me a new one...

Not a bother!

Good old phone call. 🙂 https:/www.corsair.com/eu/en/contact

I've reached out to the Corsair Support team(2005898879) and they seem to believe that the Commander Core might be damaged, so they will send me a new one. Will update this thread when I have more news.

Well.. profiles are the only thing working for me. Pump and cpu temps are messed up after the firmware update. 😐

I sorted mine by creating a new profile and setting it up there, setting it as default as well. I think this iCUE version shouldn't have passed QA 🙂

OK.. if you want to apply the Extreme preset to a specific fan, you actually need to go to each fan, where it says "balanced" and select the profile you want. 🙂 Not very intuitive, I know. 😄

Can you provide a screenshot ?

From your image Top side - Connect RGB 4 pin cables Bottom side - Connect Power PWM 4 pin cables. Right side - Press it in properly - CPU Cooler connector Left side - SATA Connection for Power, SYS_FAN connector to MB and an optional temp sensor connector. I don't see the yellow tags stating "TO RGB HUB" on your top side. Are those Corsair fans ? Here's a look at mine:

You mean this? https://www.corsair.com/eu/en/Categories/Products/Accessories-|-Parts/Commander-CORE-RGB-%26-PWM-Fan-Controller/p/CW-8960071

Current issues: - Pump doesn't seem to be working - Temps at idle on ~60 Celsius - Pump has no lighting whatsoever - H170i doesn't appear in iCUE - Commander Core appears in Other Devices(https://help.corsair.com/hc/en-us/articles/360052297652-What-to-do-if-your-Elite-Capellix-liquid-CPU-cooler-is-not-detected-by-iCUE), but H170i doesn't. Didn't try the supposed reset button in Commander Core, as I am working and rely too much on this PC for it.

Many people are inclined to believe that the latest firmware / drivers messed things up. My situation is: - H170i not appearing in iCUE - No lighting whatsoever on my Pump - I seem to get more FAN/Cooling performance without iCUE.
