Recommended Posts

iCUE version 3.26.95.

 

Only 1 out of 6 fans are working.

LED Strips are also not working and are sporadic on which ones work.

 

I'm currently running firmware V 0.9.212 on my Commander Pro.

 

My H100i Platinum is working just fine however the RGB control for the fans are plugged into the Commander Pro and those are not working.

 

I've tried forcing the firmware upgrade of the commanderpro, uninstalling/reinstalling iCUE. someone please assist.

RGB fans work in series, so the first one passes the RGB signal to the next one and so on.

Disconnect all RGB cable fans.

Connect 1 fan into port 1 on the RGB hub.

If it lights up correctly, go for fan 2 in port 2.

Go on until you find a fan not lighting up correctly... it’s likely that the former one is faulty.

Exclude that fan and see if the rest works.

 

The strange thing to me are the led strips... did you set them up correctly in iCue’s configuration?

That seems to be it... It's very unfortunate that I had 3 BAD LL120 Fans and 2 BAD RGB strips.

 

Thank you Baio

 

Plugged all Fans into port 1 on the Node and 3 out of the 6 lit up correctly.

Plugged all RGB strips into the PRO directly and 2 out of the 4 lit up correctly.

 

It's a shame that these lasted 1 year considering the LL120's ran me $120 for 3 fans. I wonder how corsair handles RMAs.

 

Thank you Baio

Mmmmhhh... too odd... too many faulty stuff, it sounds strange.

Did you try to swap CoPro LEd ports from fans to strips?

Do you use any Y splitter for the SATA power cable of the Copro?

Did you try the hard reset of the CoPro?

Maybe your didn’t find the source of the problem yet... I’d investigate a little further before opening a RMA.

Ps. Remember always swap cables with pc powered off... it’s very important!

 

EDIT: here is another try... plug a fan that lights up correctly for sure in port 2 of the RGB hub, then plug a fan that seems faulty in port 1. If the faulty one is really faulty, the good one should not light up correctly. That’s because a faulty fan can light up correctly for itself but be unable to pass RGB signal to the next one.

The more and more i play with it the more and more I think it's the commander pro. I tried an hard reset and iCUE forced me to update the firmware again on the CommanderPRO for it to even be recognized and now the Fans that i thought were good are not. very inconsistent. could this firmware version be botched?

Update*****

 

I managed to flash older firmware via Corsair Link ver 4.9.

 

Commander Pro firmware was 0.8.210 still the same issues so I ended re flashing the current firmware.

according to a new test. i have 5 bad fans. I didn't notice before because when LEDs are not working in the color white it's hard to tell.

 

Test was done with a STATIC Red setting. Shut down the computer and swapped out each fan in Port 1. See attached pictures.

 

This is crazy how is this possible? I've only had them for 1 year.

I don't think you have 5 bad fans... it's quite unlikely.

But how did you do the test? Did you just try to plug every fan per time in RGB port 1?

Did you unplug everything else from the CoPro? I see in the photos there still are led strips lighted up.

Remember RGB fans must be tested in series.

RGB Strips were still connected in port 2 of the CommanderPRO.

 

RGB Fan LED Hub (CO-8950020) was connected in port 1 of the Commander PRO.

 

Each fan was plugged into port 1 of the LED Hub while the computer was shut down. No other fans were plugged into any of the LED Hub ports.

Try to disconnect led strips and all the RGB fan cables.

Connect the RGB hub to CoPro port 1.

Test the fans in port 1 of RGB hub and find one that light up correctly.

Leave that fan into port 1 and look for the others' behaviour in port 2... and find another fan that lights up correctly

Swap the fans and see if they both light up correctly.

If you manage to do this, you should have recognized 2 fans working for sure... I mean 2 fans that both ligth up correctly AND are capable of pass RGB signal to the next one.

Then you can put one of those fans into port 1 and go ahead testing the others.

 

Whrn finished, do the same connecting RGB hub to CoPro's LED port 2.

 

VERY IMPORTANT: you didn't answer about CoPro's SATA power connection... do you use a splitter or do you have this cable plugged directly in one cable from your PSU? If it's the first one, get rid off the splitter and see if the situation improves.

 

By the way, 1 faulty CoPro is more likely then 5 faulty fans... but if I were in your shoes, I'd rather be very sure before asking for a replacement.

I know it sounds too simple, but try changing the usb header the commander is plugged into. I have had a couple iCUE problems fixed by using a different port.

 

Just tried that but unfortunately that did not help.

 

Corsair approved an RMA will update this post when it's completed.

Just wanted to post an update.

 

Five new fans came in and all is well. One of the fans pass through was not working but i just put it at the end of the sequence. I'm not dealing with the RMA process again.

 

Picture attached.

I am having similar issues as you, but I've already tried replacing the Commander Pro, the Lighting node Pro and one of the LL 120 fans by opening tickets with Corsair.

 

I'm wondering if it's a software issue and installing a fresh copy of Windows 10 might be the fix?

Was not software related with me. Best thing you can do is place each fan into slot one of your RGB hub, if it works you plug the next and so on. If the fan lights up and the next one doesn't, the fan in slot 1 could still be at fault because the pass through is jacked up. It will take lots of trial and error. to be honest it's a **** system.

 

Also the RMA process sucks. They will require you to send your fans in first or pay $$ for an up front for an advanced RMA. Which is fine, but it took almost 3 weeks and countless emails to get them to refund me my money.

 

Good luck.

I am having similar issues with the RGB fans and RGB strips. The fans light up correctly, but alternate spinning and not spinning in between startups from time to time. To add, my RGB strips don't seem to be working right out of the box.
