Thingy

Hi all I have the level 20 GT ARGB case, purchased last year in May as part of a system I had built for me. Yesterday, the two front 200mm fans suddenly lost all lighting. They had been working perfectly until that point. In my case, these are connected to the 5vRGB switchboard, but have been controlled by ROG Armoury software via the motherboard. I have a Thermaltake radiator which is controlled by TT software, which is working perfectly. Considering the leds on both fans went dark at the same time, I don't think it feasible to think both fans failed at the same instant. Therefore the next link in the chain is the 5v RGB Switchboard. Do these things fail or have any issues with failing, and is this a replaceable part? Or should I be looking elsewhere. Any other suggestions would be greatly appreciated. I have updated the TT and ROG Armoury software. Thanks in advance.
