My idiot butt got a custom pre-built just a couple weeks ago and the cooler pump has one of those screens as well. It is not working and I suspect a plug is set wrongly, but the pump works.
Fixing it would mean ripping apart the pristine cable management and I do not care about lighting as much.
Otherwise I am fully satisfied, but it niggles me a little bit to have paid 20-30 bucks more for a cooler feature that does not work.
Maybe one day when I need to rip up the cable management anyway, I will fix it.
Why even bother with shouting if you have CHIM, just open the command line and put in tcl and tgm and no-clip out of there.
