I'll bump this thread one last time just to post my resolution. Corsair support recommended that I RMA the second cooler (third time lucky?), I decided that wouldn't be worth the hassle and kept the one I've got now. It ends up that both coolers have the same lot code, so I might just be really unlucky to have got two coolers with the exact same manufacturing defect *shrug*. I've set up some iCue profiles as suggested earlier in this thread which have helped, and some random fiddling with different lighting schemes has lessened the impact. I'll update if the issue is somehow fixed in the future.

Hi all, I finally got around to exchanging my supposedly faulty H150i RGB PRO XT. I installed the new unit to find that the exact same behaviour described in my initial post is still occurring - anything other than a solid white colour on the block via iCue causes the temperature sensor to shoot up a few degrees, and syncing my case RGB to AURA causes it to rise further. :( Since this seems to indicate either a firmware issue or a compatibility issue with some part of my configuration, I've contacted Corsair support. If anyone has any suggestions for settings I can fiddle with in the meantime, or if anyone else is experiencing this issue, your input would be appreciated.

Hi all, Thanks for your replies, clarifications, and for your suggestions to adjust my fan curve as a temporary workaround. I'm going to initiate a return via Amazon after the New Year and will report back once I have installed the replacement unit and (hopefully) fixed the issue. :)

Hi all, I've been having a strange issue with my H150I RGB PRO XT on firmware v.1.01.32. When the RGB on the block is set to anything other than a solid white colour the coolant temperature shoots up. Monitoring my CPU temperature and usage shows it is still sat at idle, so the coolant a being that temperature, in reality, is unlikely. This also occurs to a lesser extent when syncing a Lian Li RGB strip plugged into the motherboard's ARGB header, which is strange as this uses Aura and shouldn't interfere with iCue at all when I have plugins disabled (?). I can change the RGB on all of my other Corsair products without this issue or anything similar happening. When experimenting I found some cases where the issue just didn't occur, such as after reinstalling the firmware or when using some linked lighting effects, but I couldn't get it to work consistently and the problem would start happening again after I restarted my computer or changed the RGB. Some other threads with a similar issue have said that it could be due to the LEDs heating up the coolant, but that seems unlikely in this case as the issue occurs even when the RGB on the block is turned off. I'm nowhere near an expert but I don't think this is an issue with iCue as the issue occurs even when hardware lighting has been set to a rainbow effect and I am idle in BIOS. I'm also unsure whether the unit itself is faulty as it otherwise works fine and I'm sure the issue wasn't occurring when I first installed the AIO and had it on rainbow puke mode 24/7, but I am able to return the unit to Amazon to test this theory if all else fails. I have tried: - Reinstalling iCue - Forcing an update to the same version of the firmware via iCue - Disabling plugins and enabling limited software control in iCue - Uninstalling Armoury Crate and Aura, and disabling Aura in the BIOS - Checking connections are firm, reseating the block with a fresh dollop of thermal paste - Swapping the AIO USB from the Commander Pro to a header on the motherboard - Using a different SATA cable (compatible with PSU) - [Edit 18th Jan 2021] Installing new H150i RGB PRO XT Things I haven't tried but might work?: - Reinstalling Windows, I doubt this would work for reason discussed above - Updating motherboard BIOS, it's early days for the 5900x so maybe the processor or BIOS is doing something funky? Any other suggestions on why this could be happening and ways to fix it would be appreciated. My current workaround is to keep the AIO on a solid white colour and unsyncing the RGB strip from the motherboard, this works fine as I have been running it on solid white before I even knew about this issue, but I'd love to take full advantage of all the RGB effects at some point.
