This evening my PC randomly shut off while I was gaming and then again when I turned it back on again. Now it appears to be fine and I was looking at the PSU stats to see if anything was unusual and I noticed some impossible spikes. I've attached a screenshot of the log, interval was set to 1 second. Note the 2kW spike at the top as well as the 230c temp spike at the bottom. Obviously neither of these happened otherwise I'd have serious issues. While I was typing this, although logging was stopped, I just noticed a 60kW spike! Motherboard is a Gigabyte X570 Aorus Master, I have the USB cable from the PSU connected to an internal USB hub. I only have 2 internal USB 2.0 headers, one has the hub connected and the other has my H150i. I had to take my H150i off the hub as it was causing impossible coolant sensor spikes that were ramping up my fans. I'm wondering if it's the same issue, but I have no idea how to fix it. The hub is the frequently recommended (here and elsewhere) NZXT Internal USB hub, not the new gen 3 one though. Do you think it's worth buying the gen 3 and see if it's a hub problem?

Thank you for your help, I really appreciate it. If I tilt the case forward the pump makes a rapid popping noise, kinda sounds like bubbles. It's always run kind of hot, I have it on top exhaust and a very low speed idle profile, it's more aggressive as it gets hotter. The coolant temp has calmed down now though. Mobo sensor says 28c and the coolant is at 38c. As I type this though, it dropped 2c in about 5 seconds and then went back up again to 38. Is there something more I should try regarding trapped air before I open a ticket?

Currently the coolant is elevated and it's hovering around 40c. It doesn't seem like a blockage as it'll ramp up gradually for gaming then cool down afterwards. Literally as I was typing this the coolant temp just dropped to 38c and now it's risen up to 40c over the space of 10 seconds. I have MSI Afterburner and RTSS running, but the only Corsair sensor they poll is my PSU (I have the AIO a CoPro and two Lightning node Core) and I've been running those since day 1 of me using the AIO. It hasn't been an issue and there haven't been any recent updates for them either. Beyond that, closing them doesn't correct the errant behaviour either. I do have a custom cooling profile and it is definitely tracking the coolant sensor.

I have an H150i RGB Pro XT and randomly it'll get incredibly noisy due to the coolant spiking rapidly. The coolant will rise up to 10c within 20 seconds or so and cause the fans to go nuts. It's doing it right now and all I'm doing is browsing reddit and watching Twitch, 3% CPU usage. Then, after some minutes, the coolant temp will suddenly drop and it'll go back to normal. For reference, I have a 5900X and the H150i is using the "H150i RGB PRO XT Temp" sensor and the radiator is mounted on the top of the case.

I haven't had any problems with the CoPro, pass-through seems to be working just fine. I had ARC on the slowest settings on both Cores and it had been synced up until today with the freezing. I've obviously removed the offending fan, but the sync problem is still there. I've updated my chipset drivers. I have the fans on a two colour shift now, so I shall wait and see what happens with that. I appreciate you taking the time to answer.

The motherboard has two 2.0 ports and two 3.0 ports. For the 2.0, one has the AIO and the other has the CoPro. The 3.0 are being used for front panel USB slots, none of which are currently in use. Both devices work on both 2.0 ports. The loss of function seems to be random and as, when working, both devices function fine on both ports, it's a tough one. As for 2.0 devices, aside from standard peripherals, I have a monitor pass-through that has a Bluetooth receiver and a USB sound card on it. The receiver is only used for my xbox controller and I also have an additional K63 keyboard, neither of which are left on. The sound card has a small 3.5mm jack mic plugged in, which I haven't used recently. I shall check to see if chipset drivers are up-to-date. As for the cores, they're both running the ARC program. I'll change them to a simple 2 colour shift and see what happens.

The lighting node that didn't get detected once is now having new problems. It's slowly losing sync with the other node is frequently freezing, the leds are freezing. I have an RGB off profile and if I switch to that, the fans in the freezing node stay lit. Except the bottom left quadrant of the first fan on that node, that responds just fine. Then randomly it'll resume the rgb pattern, but still out of sync. They also hold their colour longer than the others when rebooting, as opposed to changing to white. They flash sometimes too. edit - I've done some troubleshooting. Am I right in saying that the lighting node core signal works in sequence and loops? The fan that had one quadrant working was in position 1 in the hub, unplugging it and moving 6 into 1 restored working order. The faulty fan is now unplugged from the node, but it's still losing sync with the other one. Could that in anyway be causing my AIO problems?

I've recently changed out my case, cooler and fans and now have a H150i Pro XT, using the 3 fans that came with it, and 10 QL120's. However, both the AIO and one lighting node will randomly not be detected. I have two lighting node core, one with 6 fans and the other with 4. They are both plugged into the usb headers on the commander pro. The QL fans double up with 4 splitters to get all 10 on the commander pro. The 3 AIO fans are connected to the AIO and powered separately. Each fan is rated at .3a with 3a in total across all fans. This is under the commander pro limit of 1a per port and 4.5a in total. The commander pro and the AIO each have a usb 2.0 header on my motherboard. My motherboard is a Asus Maximus VIII Hero Alpha. All firmware and software is up-to-date. The first time the AIO didn't show up iCue, I turned everything off and switched the AIO and the commander pro headers, to test if one of the headers was faulty. Upon switching, everything worked fine on next boot. The last two times the AIO hasn't shown up, I've found a Corsair device as "not connected" in usbdeview, uninstalling it and rebooting has brought it back. One time a lighting node core wasn't detected, rebooting fixed it and it hasn't happened again. I'd appreciate any thoughts or input people have.

Thank you for your help, I really appreciate it.

You're absolutely right, I don't need separate speed control for that many. Ultimately, they're probably all going to be running the same speed. I meant RGB control, some of the cooler patterns involve having only one fan lit at a time. Is that still possible on a splitter cable? edit - I think I understand actually. The RGB control comes from the Lighting Node CORE. As they have 6 ports and I'd only need 2 of them. I then connect those 2 Lighting Node COREs to the Commander PRO. Then as far as PWM control goes, as you say, 3 would be controlled by the AIO and 7 from the Commander Pro, with 2 of them doubling up on one port. Is that correct?

That's helpful, thank you. As far as RGB control goes, would the 2 fans that share the same port not be controllable individually?

I'd like to buy 10 QL120's and a H150i RGB PRO XT. 3 to replace the fans on the H150i and 7 for the case. I've had a good search on this forum and read Zotty's thread on how this all works, but I'm still confused as to what additional items I need to buy. As it stands, I'll have: 1 H150i 10 QL120's 3 Lighting Node CORE What else do I have to buy for maximum functionality? As I understand I'll need at least 1 Commander Pro and some fan splitters, but I'm not sure if that's it and how they connect to each other. Any help would be greatly appreciated.
