980 SLI LED Issue

[DaedalusOS]

So, I just got my second 980 (Woohoo!) and the first thing I noticed is that the LED's aren't the same brightness, and it's a pretty significant difference. (Sorry for potato quality)

Any ideas as to why the LED's aren't the same brightness?

 

I've tried:

• Changing them (same time and individually) in GeForce Experience
• Pushing both cards in
• Pushing in power cables

 

Both cards are running at PCI-E x 16 as well.

Can you not adjust the LED' s in GeForce Experience?

Setting to 0% then back up to 100% still didn't fix it.

Have you ever removed the fan shroud on the one that is less bright? It appears to have it's LEDs pointed down. You can see in the picture that the brighter one is shining onto the heat sink differently.

Closer look the LED's are in the same position. And no, I've never taken the shroud off the top one, I've only had it for about 2 hours now.

Well that's a shit. If you can set the intensity, you could match the brighter one to the dimmer one. I'm assuming they're the same model.

 

I run mine with one plug from the cable on each GPU, my hypothesis is this allows the cables to share the load rather than being responsible for a GPU each. I see no possible way it should impact the LED but it's a thought and something to try.

It's quite possible they just updated it with a brighter/dimmer led. If you can, I'd try to reduce the one to make it match.
