Rog Ryujin II 360 Malfunctioning

Level 7

My RoG Ryujin II 360 is suddenly not working. Whenever I turn on my PC, fan spins really fast and the CPU Temperature keeps on increaing til my PC shuts down due to CPU high temp despite the AIO Fans spinning at full speed.

I noticed the only fix for this is when starting the computer and when fans starts spinning fast, unplug the cable from the AIO to fan hub and replug it again to the fan hub and the temperature suddenly goes down. I think the pump is broken since fans still spins fast but the temparature still increases.

I also noticed on Armoury Crate, there's no AIO Fan Controller.


Sometimes the Fans on the radiator doesn't spin as well, the only way to fix it is the same as what I stated before, to unplug and re-plug the AIO to Fan hub. So I don't know if the Fan Hub is broken and I don't see anyone selling the RoG Ryujin Fan Hub

I'm really not sure if the issue is the Fan Hub or the Pump itself is broken or everything on the AIO is broken.
