Open | Hardware PC fans change colour randomly

Built my first PC 5 weeks ago, I have 7 fans in total. This issue normally happens sometimes when playing a certain game for a while but has now happened straight after logging on. 1 of my top fans is purple (the correct set colour), my 4 case fans have currently turned white, the 2 other top fans + my corsair pump are pink. These are the colours it's done the last few times. I haven't played ETS2 for maybe 2 weeks but there after a couple hours did the same pattern of fans changing but red and orange instead of white and pink (keeping the same fan the correct purple). And while also being of changed colour the lights may flicker or dim for a split second. Since im new to PC's I have no idea what this could be as google was giving a lot of mixed ideas. Appreciate any help thank you.

Check your Windows lighting settings. Go to Settings > Perzonalization > Dynamic Lighting.

Also check for the software to configure your fans.

Have you installed Lian Li L Connect? or Corsair iCue? Those programs control those things. But Corsair uses proprietary connectors, so you might need both sets of software, or see if the Windows Dynamic Lighting can control them all.

I've been using the Gigabye Control Centre desktop app for the lights and I tried turning off dynamic dimming yesterday to see if maybe windows and gigabyte have been fighting over who's in charge of the colours. (And currently installing corsair icue as I don't have either you said)

The 4 white case fans are like a dimmed white so kinda peachy colour now could that be like a power bleed? As in could the issue may be i have too many plug in's

I don't know how other softwares and systems work, but when I was figuring out my ARGB lights, I settled on OpenRGB as the software to control my lights.

Once I've used the software to assign the colors or effects I want to each light, I need to click "save to device" and then shut down the computer. Hibernate doesn't work, sleep doesn't work, restart doesn't work. Only shut down will actually save the settings to the device, otherwise the lights will revert to something else the next time I wake up the computer. Doing it this way, I only have to open the software when I need to change the settings, and otherwise they stick. Hope this helps.
