Only RGB from Fan 1 of 3 (CoPro and RGB Hub)
 
5 Attachment(s)
Having searched an read much of what has gone before I think this warrants a new thread due to the setup:

Issue: I can only get RGB lighting from Fan 1 (of 3) when connected to the RGB hub. I have tried all 3 fans in port 1 and they all get RGB in that pot but only that fan. ALL FANS SPIN UP.

I have connected the following:
3 HD120 fans into the RGB hub with 3 pin cables and 4 pin cables on the CoPro
RGB hub into LED 2 on CoPro
CoPro detected in iCue and I setup 3 HD120s on Lighting Channel 2 with raindow effect
CoPro did a firmware update too so i completed this before setting up the fans in iCue.
Both RGB Hub and CoPro are on their own single sata cable from the brand new corsair 750w PSU

Testing:
  • All fans spin
  • All fans RGB work in port 1 on the RGB hub (no RGB from other fans
  • I have re ordered the fans on the RGB hub connecting in ports 1 2 3 but only port 1 will work for RGB.
  • Prior to the CoPro introduction, fans all worked correctly using the RGB hub and the HD lighting controller.
  • iCue up to date
  • CoPro Firmware up to date

What have I done wrong?
All fans work (if in port 1 on the RGB hub) so it must be a connection or software issue.

I note that in icue all 3 fans display but only one is achieving 12v the rest are much lower.

supplimentry test - thought it was a power issue.

moved the RGB HUB onto another sata cable but this hasnt acheievd anymore.

Would connecting the fans back onto the mobo headers provide more power? / solve the issue?

Gigabyte z270-hd3p is the mobo model

ok something has happened

I now have RGB to 2 fans (slots 1 and 2 on the RGB Hub) but the second is just white except for 2 of the leds, 1 is yellow and 1 is pink - constant colour for all leds on that second fan. the 3rd is still dark.

Ok for fun i powered off and connected the lighting control back instead of the CoPro. Now just 1 fan has full colour the next one only has one led lit and the 3rd is dark.

dodgy fan?

Hi Disocpete,

Could be a bad LED on the 2nd fan. You can test by swapping fan 2 and 3 on the hub. if it doesn't help it's likely the hub itself.

All the fans work if in slot 1 of the hub so I think it's that

Just because they all work individually in slot 1 doesn't mean that they are good. The fans pass signal to the next fan in line and this is what typically turns out to be the issue. So you need a known good fan (that works in slot 1) on slot 2 AND verify that the fan works in slot 1.

But as I've said, each fna in slot 1 works but none of the others do in slots 2 and 3 so how can I determine a bad fan when I get all the same results with the fans in the slots as you describe.

Logged with support so hopefully they'll sort me out (rma)

Corsair have RMA'd the fans for me- got new ones. all working, now waiting for a new CoPro <> RGB Hub cable (doh) and then I'll be in business. The fans are working off the RGB controller for now.
