I've been talking with support, and they asked me to remove the USB cable and replace it with one of my own that plugs into a USB A port in the back of the computer, rather than the included cable that connects to the motherboard. When I did this, nearly ALL of my problems completely disappeared. As unlikely as it sounds, it seems to be the USB cable connected to the pump that was giving me problems. They are sending me a new one. The one problem that hasn't been resolved is the initial disconnect every time I reboot the computer. I have to go into iCUE and click the "Restart iCUE Service" button in Settings and it comes back up. Having this relatively minor issue that only comes up on reboot is WAY better than what was previously happening. It's still a problem that needs to be resolved, of course, but I no longer regret the purchase like I did at first. My recommendation is that you open a ticket with Corsair Support for any problems you're having. They seem a bit backlogged at the moment, so it may take a few days, but they'll get back to you and they've been quite helpful. Good luck!

Momorious, out of curiosity have you updated to the latest iCUE software, 3.11 from a couple of days ago? I was having the same issues as you, and updating the software resolved 90% of the problem for me. I still get disconnects, but instead of constantly, I've gotten one on reboot (resolved by quitting and restarting iCUE), and then one more disconnect while the machine was running. Resolved by changing to a different profile and then changing back to the original one. This disconnect has happened only once in the 48 hours since the software upgrade. I still have a ticket on these remaining issues, but once every day or two is WAY better than before.

Update: Corsair has gotten in contact with me. As I mentioned above, the problem was mostly resolved by the last software update, but I still sometimes get a disconnect on reboot, and so far I've gotten one during a game. But that's only once in about 48 hours, which is way better than every 15 minutes like it was previously. Hopefully they'll have something I can do to resolve the remaining problems, though I expect it will require another update.

For what it's worth, I haven't been able to thoroughly test yet, but updating to iCUE version 3.11.114 and then rebooting so far seems to have resolved most of my problems. I'm trying to watch out for anything out of the ordinary because I don't fully trust that everything is fixed yet, but so far so good. :)

I put in a ticket for the problem, so did fedaykinwolf above. I don't know how he's faring, but I have yet to get a response. I imagine they're drowning in similar tickets considering how common it seems to be in the forums. But for now, every time I hear the disconnect noise I go into iCUE and select a different profile, and then re-select the original one. That seems to get it going again most of the time. When it doesn't, I quit iCUE completely from the taskbar and restart it. For what it's worth, in my case the fans don't completely stop when I get the USB disconnect chime. They drop to 500-600 rpm according to iCUE (weird that the driver stops working on disconnect, but the temp and speed sensors continue to report values). I haven't noticed the pump speed dropping, which is good. Changing the profile and changing it back kicks the fans back into action and they speed back up to the appropriate speeds, and I see the temperature start to drop. Of course, that's not a real solution. I shouldn't have to be doing this every 15-20 minutes. Luckily I haven't seen the pump temp rise above 35C, but that's usually where it's hanging out when the driver has zoned out for a while.

That's interesting. I wonder if one of my USB devices is causing the failure. I've got a couple of external drives, a card reader, a microphoone, a CAC reader, a couple of scanners, etc. I'll have to try removing everything else and plugging them back in one at a time to see if one of them is conflicting.

No, unfortunately it's still happening. It seemed at first that it was only happening on reboot until I had a chance to restart the service. But it turns out that that will fix it for a while, maybe 30-60 minutes, and then it starts again. Whenever I start hearing the disconnect chime again, I have to restart the service and reselect my desired profile for it to start working again. The error is the same every time in the logs:

Okay, so partial update and additional info: I updated the chipset drivers and a couple of other things that were available for my motherboard (Asus ROG STRIX x399-E Gaming). I updated the BIOS to the latest version. I updated to the latest iCUE (3.10.125). Upon restart, the issue started happening again. After spending a little time on it, I turned on debug logging and noticed an error: I've also noticed the following with the current setup: This ONLY happens on startup (so I doubt it's the cable), the USB disconnect sound happens every 10-20 seconds. When I bring up iCUE, it has reverted to the Default profile, but the actual settings are not active (ie, the Default profile has the "Extreme" setting on the fans which should put them on at 100% at 30C, but at 32C they're only going about 500 rpm). I can change the profile, but the fans don't speed up even though they should. The disconnect sound keeps happening. Then I quit the iCUE service and restart it. It's back to the Default profile again. But now that I've restarted it, the fans are working as expected (100% at 32C until the temp drops below 30C), and changing the profile seems to work as expected. The disconnect sound stops for good, until the next restart. After the next reboot, the process starts over again. I have to quit the iCUE service that's auto-started on boot, and start it again myself. Edit: never mind. After letting it sit for 15-20 minutes, it started the disconnect noise again. It wasn't doing that after restarting the service, until just now. But this time without restarting iCUE, I was able to go in to the application where the profile had NOT switched to default (but the fans had slowed down), I changed the "Performance" profile and then back to where it was (Balanced) and the fans immediately sped up to appropriate levels. So weird. And now the disconnect sound is gone again.

My apologies, got sent out of town for work and just got back. I'll update you once I've installed the motherboard drivers and tested with a new cable. I really appreciate your help!

Well, the disconnects only happen on startup and will continue to happen until I bring iCUE to the foreground by clicking on the taskbar icon. Once I bring iCUE to the foreground, it stops disconnecting and I can close the iCUE window and it's fine. Although since it has reset my active profile to "Default", first I have to re-select my desired profile. If I reboot and the disconnects start happening, I can quit iCUE from the taskbar and the disconnects stop. Then I can start the application, re-select my desired profile which has been reverted to "Default", and it's running fine. I don't know, to be honest. How would I find this information? Disabled, although the behavior is the same regardless of how I have this set. Directly to the motherboard using the included cable attached to the pump and to the USB header.

It's the Platinum. :)

Hi, I just bought this H115i RGB cooler to replace a dead Enermax cooler. I'm pretty sure everything is connected correctly, since it's mostly doing what it's supposed to do. I'm using the latest iCUE software (currently 3.9.93). For a while, the software was locking up for 20-30 seconds every time I tried to click on a different profile or change tabs (ie, from "Home" to "Settings") where Windows 10 would report it as "Not Responding" for a while, and then eventually come back and respond to clicks again. Of course, as of this morning this behavior has stopped and it's running normally after no particular intervention from me. Not sure what that was about. Moving on, I've had a couple of strange behaviors popping up, but they've been hard to nail down. Things like the fans occasionally not paying attention to the performance setting (ie, they'll be at 600-700 rpm with the coolant temp at 34C, when the Extreme performance option has them running at 100% after 30C. Then as soon as I bring the iCUE app up, they bounce back to 100% like they were just caught by the boss slacking off). Of course, as I'm typing this I can't recreate it, go figure. More annoying than that though is the constant disconnects that seem to generally happen after a reboot. I'll be on my creatively named "Profile 2" and then I'll restart the computer. Colors change to the Default profile, and once I'm logged in I start getting the USB disconnect sound in Windows, about every 10 to 20 seconds. I never hear the "connect" sound like the user in this thread, just disconnects over and over. The colors remain in the Default profile. If I go into iCUE at this point, the profile has been reset to Default. I can reselect Profile 2 and things go back to normal, and from that point forward I stop hearing the disconnect sound until the next restart. This problem is repeatable, and I've created a third profile with a different lighting scheme and it exhibits the same problem. For reference, Profile 2 had the pump on one of the rainbow modes, and each fan was on Temperature (one for the coolant, one for the CPU temp). Profile 3 was just set to Heartbeat.
