If you're running an Asus motherboard, this sound like your system is doing a memory test on cold boot (normal). This should only happen after you've unplugged your power supply or perhaps tweaked your memory settings in BIOS. Your system specs would be helpful...

I think you just got lucky with your LLs. I'm about to replace my 5th fan in just under 2 years for failing LEDs. I did an RMA with the first one, but after the outrageous return cost from Canada to the US, I've just been purchasing new. Not really a cost-effect RGB fan solution is it?

If you're running in that order, I'd be suspicious of the front top (fan #1). Remember they run in sequence, for example; if fan #1 has a fault, it wont send the correct signal to fan #2, causing issues with every fan after that. It might be best to unplug all your fans from the RGB hub and test them each individually (using port #1 of your RGB hub). It probably wont take long before you find the culprit. Make sure to test them all though because there could be 2 bad fans. I've had it happen! On another note, I haven't ignored the GPU temp concern. It could very well be a PSU power issue as I'm sure your temps only rise when under load. However, it looks (at least to me), to be a simple fan issue. Of course, I could be wrong. Maybe others will chime in...

You have a bad fan (LEDs) - which fan did you replace? Remember, the fans run in series. If I was going to guess, I'd say that bottom front is your culprit as only half the LEDs seem to be lit. I'm going to presume the bottom fan is #1 on you hub? If so, as a test, unplug fan #1 RGB connector from your hub and plug fans 2, 3 & 4 into ports 1, 2 & 3 on the hub. See if that fixes it. As a precaution, do not hot-swap the hub RGB connectors (shut down first).

SP RGB Pros are not compatible with the controller. See the link to Guide/FAQ below: https://forum.corsair.com/v3/showthread.php?t=173880

I can confirm the same issue. Assigned lighting/LEDs on LED strips are deselected.

It looks like one of those first two fans has a bad LED (or issue) and it not passing the signal to the remaining fan(s). The RGB in these fans work in series therefore, one bad fan will interrupt the signal and cause issues like you are seeing.

No problem!

I know you have stated that you are not running any additional RGB software however, last time I ran into this, it was related to the Asus Aura plugin. Have you tried disabling Plugins and maybe even SDK under your iCUE settings? It might be worth a shot...

You can't mix and match different fan types on a single hub. If I am understanding correctly, you would need another Lighting Node Pro and another RGB Hub to run your QL fan. Alternatively, you could use a Lighting Node Core which is basically the Node Pro and RGB Hub combined. For now though, I highly recommend you refer to the RGB FAQ and Setup (which includes extensive wiring diagrams) linked below: Zotty's CORSAIR RGB Hardware and iCUE Eco-System FAQ https://forum.corsair.com/v3/showthread.php?t=173880

My Daughter had the same issue when playing Fortnite on my PC. iCUE was crashing in the background/locking up random colors. The fix was to uninstall Aura as the Aura plugin (and it's anticheat issues) seemed to effect iCUE directly.

What Baio said above. For now (until it gets fixed) go into your setting and disable 'Plugins'.The problem most likely is that Aura and iCUE are both fighting for rights to access your RAM.

At this point, it would be beneficial for you both to fill out your system specs.

What specific performance tab are you looking for?

Well, you don't see a performance tab because you haven't selected a device. For example, click on your Strafe keyboard or your pump (yes, I know the pump is missing at the moment). Your fans should show up under your lighting node pro. Have you added them under Lighting Setup in your node pro? As far as your pump, is this a new issue? Have you tried basic things like disconnecting the USB cable from the physical pump and/or motherboard and seeing if iCUE picks it back up? If it was me, the first thing I would try is temporarily uninstalling ASUS Aura and seeing if that has any effect. Fan setup example Pump performance tab example

That rig Zotty. Nicely done! :bigeyes:

That's not the way it's supposed to work. The Aura plugin is designed to control your ASUS motherboards RGB lighting (only) via iCUE and not the other way around. Essentially, you aren't supposed to open Aura, just install it, leave it, and let iCUE take control of your motherboard lighting. Now, if you own other ASUS RGB products, the plugin may not be the best solution for you.

If you're testing fans singly, this will not work. A seemingly good (working/lit) fan might still have trouble passing a RGB signal to the next fan in line.

Glad you got it sorted!

I've seen way more EVGA PSU failures than Corsair and, i'm a big EVGA fan.

I'd uninstall both ML and HWM for now (yes I see you've tried that a some point). The way i see it, something could potentially be fighting for USB rights on your system.

What other software are you running, and I'm talking about anything that monitors your system or controls RGB? What version of iCUE are you running?

This sounds like a bad fan in the loop. Corsair RGB fans run in series passing RGB signal from one fan to the next so, one bad fan not providing the correct RGB signal can cause issue like the flickering you are observing. Now, the fun part is you will have figure out what fan is causing your issue. Basically, you will have to test each fan by methodically moving them around in your RGB hub (only move them around with the power off) and test until you find the culprit(s). Remember, the RGB connectors on your hub must be in sequence, therefore for example, 4 fans on a hub, ports 1,2,3 & 4 must be populated without missing a port.

Every time I read a post like this it makes me wonder what the underlying issue is with different builds. I've been running a full Corsair built system for over a year without a single issue. There has to be some kind of common denominator here. Out of curiosity, are you using internal USB hubs etc?
