Just bought an H150 Elite LCD XT and have the triangle exclamation issue. Have done all of the troubleshooting steps posted here and other places. It is unrecognized in iCue (except it did show it as a detected device when I was reinstalling iCue). Pump seems to work fine as I can hear it running and the CPU stays cool. If I close iCue, it switches from the exclamation to just showing the Liquid Temp 0deg screen. The LCD is plugged in directly to a USB header on the motherboard along with the commander core. Commander core and all the fans connected to it work fine. I verified the 20 pin connector is fully inserted. Unplugged it and plugged it back in to be sure. Verified the LCD is in place and fully pushed in. Uninstalled/reinstalled iCue. During installation of iCue, it shows the LCD as a detected device, so I know the USB device is being recognized by Windows. I am confident there is no more troubleshooting left to do. I seen warnings not to unplug/plug in the LCD while powered on, but I didn't do that. Submitted a ticket to Corsair. Is it possible they can replace just the LCD, or am I likely going to have to rip my machine apart again and returning the entire unit?

Disabling C3 state definitely solves my problem with this board and laggy explorer. I can now run iCue without any problems. I'm running an Asrock Z390 Phantom Gaming 6. So there must be some issue with Asrock's UEFI or board design/implementation of the Z390 chipset.

Yeah, I've done a lot of research on the interrupt issue, down to disabling some things in the NIC driver that were suggested by Intel, but nothing has helped. I work in IT and manage an environment of ~150 PC's, so feel like I have a very good reference point for system performance, and a machine with mostly top-tier specs like mine feels sluggish, worse than my workstation at work. I have the board loaded pretty good - 2 NVMe SSDs, 2 SATA SSD's, dual port NIC, and sound card. I'm going to try stripping it down to just what I need and see if there's a change before trying a fresh OS install. It feels to me like whatever lag iCue is causing is already there, it's just amplified when iCue is running.

Interesting. I have a couple spare SSD's laying around and have been contemplating a fresh OS install on one of them just to do some testing. I have been having another issue where I will have a spike in "System Interrupts" caused by something in the networking stack that causes the entire system to freeze. Unplugging the ethernet cable from the NIC immediately brings the system back until it happens again at some random point. Done all the usual SFC stuff, updated BIOS, all driver's, etc. The issue happens with every NIC I've tried in the system across Intel, Broadcom, and Realtek. Maybe this board is just trash. I feel like there is some weird lag in explorer even when iCue isn't running, but when iCue is running, it's horrendous.

I have the exact same problem. I have to shut down iCue in order for me to not want to rip my eyes out navigating through explorer. It also murders the 3D viewport performance in Autodesk Inventor and makes it unusable. All the solutions mentioned here have already been tried. Asrock Z390 Phantom Gaming 6 i7-9700k w/H100i Platinum RGB 32 GB @ 3200 RTX 2070 Corsair RM750i Commander Pro Strafe RGB Windows 10 1903 (happened on 1809 as well)

I have the EXACT same problem. It totally obliterates windows explorer. I also use Autodesk Inventor for CAD work and it completely ****s on the 3d viewport and makes it stutter and freeze so bad it's unusable. I have to kill iCue to have a PC that doesn't feel like it's 10 years old. I wonder how many people have these kinds of issues and don't realize it's caused by iCue. I've done the DLL rename from one of the other threads and that doesn't help at all either. I submitted a ticket to support for it (#2000794485)
