Corsair h150i elite capellix issue, Pump seems to be on, but no lights.

[loggcole]

So I recently finished building my new pc. A lot of this is all new to me so I have ran into a lot of problems that I am being extra careful with, anyways Specs listed below. When I initially plugged everything in after installing windows everything worked fine. The AIO Pump showed up in the BIOS and showed around 2000 RPM. I have the AIO pump header plugged into the AIO_PUMP on the motherboard, and the AIO Power cable was plugged into the Corsair RGB Hub, which had the 3 case fans and 3 fans from the AIO plugged into it. The Corsair RGB Hub is plugged into the USB 2.0 slot on the motherboard. The case fans did not show up in the BIOS. CPU was around 25-36 degrees. I booted up my pc and at this point everything was still working. The fans and AIO were both on including all RGB. After booting up my pc, i began installing and downloading all my drivers, and other software including Corsair iCue (v4) and Asus Armoury Crate. I'm not sure what happened to cause this, but all the fans and pump started to flash red and the fans speed increased dramatically. The AIO read "pump failure" in iCue. Thinking back on it, it might have been after I updated all of my corsair drivers (fans, aio, keyboard, etc). Anyways, I did some research and the first thing I tried was unplugging the AIO power cable from the RGB Hub and plugging it back in. I tried that and the flashing red lights and high fan speed stopped. The case fans went back to normal but the AIO Pump RGBs did not turn back on. Now in iCUE, the AIO Pump did not show up, and now all I could see was the RGB Hub. The cpu seemed to stay cool so I figure that the pump was working, but the RGBs were not. I could feel liquid being pumped on the tubes which basically confirmed this. I looked up some ways to fix it and I first tried uninstalling Armoury Crate as it could interfere with iCUE, did not work. I  then researched some more things and tried closing iCUE, then forgetting the RGB Hub in bluetooth settings and then scanning my device manager for updates and did not work. I also checked all cables and moved the AIO Pump header from AIO_PUMP to CPU_OPT and CPU_FAN, which did not fix it. I also read that it could be because I have my k95 keyboard plugged into the back of my pc, which could make it so not enough power is being allocated for the AIO, or something like that. Anyways I moved them to the front of my pc and still did not change anything. Last thing I tried was this morning, I turned my PC off and turned the PSU off and unplugged it for a couple of minutes. Still did not work. 

I'm not sure if i have to keep trying some of the fixes to see if they work after trying multiple times, or if its beginners "un" luck. I think the AIO Pump is working, I played 3 games of valorant last night in which i had High FPS on the highest settings with no issues. My cpu would have overheated by now if it was not working correctly right? Anyways, just looking for some help from the community or from corsair directly. This whole first time PC building experience has been a hastle and it would be a huge pain if I had to return it and replace it in the motherboard. Please let me know! Thanks.

Double check the 20-pin plug that goes into the Commander CORE from the pump head. Sounds like it might be loose or not fully seated, hence why it's not showing in iCUE and some of the features are working. There's a white line on the plug that should match up with the white line on the CommCORE housing. 

Can also use the included allen key to take the 4 screws off, pull the top RGB module off the pump, and then replug it in and screw it back down. Maybe one of the 9-pins under the cap isn't contacting something. 

Also, you should never unplug stuff like the 20-pin when it's in use. That has a tendency to cause things to break break with inrush current. If it's not detecting the cooler at all anymore, I would say that you should RMA it.

White lines match up from pump head to Comm CORE. I could have unplugged it while it was running, how do I go about RMAing it? Is that a replacement one or just getting it fixed?

[shocksim]

It would be a replacement. If you bought it from a retailer within the last 30 days and their return policy is still in effect, that would be the fastest way to get a new one.

Replacing through amazon, hopefully a new one works. Will update when received and put back into PC! Thanks

Just remove amazon and deal with corsair direct. it will speed things up by days. Anything i've emailed support i get an answer back 1 or 2 days later.

If anybody is having a problem with a brand new pump not working / showing up on icue / no lights / no info being sent to pc such as rpms of pump or fans, I think I have the solution. After messing with my buddy’s pc for 2 days it became clear that it was not a software issue and it wasn’t a matter of incorrectly plugged cables. The pump was receiving power it seemed (maybe it wasn’t) but not lighting up or even being detected by the pc or icue or giving feedback to either. So I went and bought a brand new pump to see if maybe the pump itself was faulty or just a component. Before I put in any extra wasted effort I figured the best thing to do was to switch the easiest components first. I started with replacing the RGB Module (on the h150i elite capellix) on the pump itself that plugs into the commander core with the 3 pin wire that sends the rpm info to the motherboard. I replaced it with an lcd version from the same pump model and now the pump turned on leds and screen turned on, however as soon as the pc got passed the boot screen, the screen showed the “pump failure” logo and the rgb fans flashed red and were running full speed. However the pump was indeed working and was detected by icue. I tried undownloading icue and redownloading and force updating it as well and neither fixed the issue. So I turned the pc back off and replaced the commander core with the new one that came in the box with the new pump and after hooking everything up and turning the pc on, my problem was resolved. The pump ran perfectly and icue detected the pump and all fan rpms were showing as well. So long story short. If your having the issue of a brand new pump (this was for the h150i elite capellix) not working out of box and no rpm’s showing even though the fans are spinning, the commander core is most likely the problem. If you want to save money, either return it where you bought it or file a claim with Corsair for a replacement. If you wanna save time just order the commander core replacement ($40.00 part) or go pick it up from Best Buy.

Did you get the new one to work?

It is the janky software and USB connection if you just bought it, replace the unit with another manufacturer with only the AIO header connectors. All your problems go away or after a few RMAs
