Corsair h80i v2 and iCUE freezing

[gambler]

I'm having this issue and I found out it's probably caused by user-made custom profiles. But not all custom profiles I made will freeze ICUE, which is weird. I can't use the ICUE default cooling presets because the coolant temperature in my system is high, between 40 and 52c under load/gaming, turning the fans into a Boing 747s. Setting 2800rpm on 120mm fans was kind of a bad idea, Corsair.

I'd like to know if it's possible to plug the H80i v2 on the AIO reader of the motherboard which always provide full power to the pump, while plugging the two radiator fans on CPU_FAN and CPU_OPT. I know I will lose temperature sensors from the pump (for me it's useless anyway), but I would be able to control the  fans using the motherboard software (reinstalling AI Suite). Just like I used to do with my H100X. And in case it's possible, I also would like to know if I can disconnect the USB cable as well.

The freezing is not related to the custom profiles.  It is more likely crashing due to software conflict with another monitoring or RGB program or underlying PC issues that show up under load.  That may be hard to sort out.  You can use the two radiator fans on CPU+OPT.  In the BIOS, make sure you give yourself some fan delay or hysteresis as you will be forced onto CPU temp as the control variable and its underlying behavior was meant for air coolers.  You should be able to set 8-12 seconds of delay on CPU fan and that should mitigate most of the up/down ramping.

THe H100X I had always worked on CPU temps just fine, as it doesn't have USB control. the default presets from ICUE for coolant temperature are way too aggresive even in the quiet mode, I think Corsair made the default profiles for people who live in Siberia. While gaming, coolant can easily get to 50c in tropical climate and that's far from critical point to make the fans run at 2800rpm, which makes it just unbearable to the ears. That's why the only way out is creating a custom profile and let CPU temperature handle it, or even coolant but higher. But then the program freezes, and yes, I think it's sensitive to the fan curves programmed, because a specific custom profile I made never crashes unlike the others.

The USB is only for the ICUE software so it wouldn't be needed right? I just plug the pump in the AIO reader (always supplying full speed) and the fans in the CPU+OPT.

If you disconnect the USB you will not be able to access the pump speed or lighting.  Otherwise it has no effect on operations.

Can ICUE still be used for the pump when the two fans are connect to CPU and OPT? (I would be using Asus AI Suite as well to control fans)

Yes, you will still have pump speed in CUE which you don't really need to be changing around.  Set it and leave it.  That also means if the H80i v2 is the only CUE device, you can set CUE not to run on start up (check box in CUE settings).  The fans on CPU/OPT will be controlled through the BIOS QFan or AI Suite.  Make sure you give yourself some fan delay on spin up/down.  On CPU fan I think you will be limited to 8 second delay max, which will be fine.  On CHA Fan headers you can use 12 sec delays.

The AiSuite already configured similar fan settings automatically including the delays. And for some reason the H80i v2 is running about -5c to -7c while gaming with the fans controlled by the motherboard/AiSuite (no change in ambient temperature), even tho I'm using the same custom fan curves I had on ICUE.  AISuite also reports the pump speed, which it's about 1400rpm (x2), so the same 2800rpm as reported by ICUE I believe.

ICUE also didn't crash yet, but needs more time running while gaming to determine if it's a solution.
