Review on ASUS ROG Ryujin 240 Liquid CPU Cooler with Live Dash OLED in Black by Craig Sexton

Not a bad cooler. However, if you set the OLED screen to a static image or hardware information mode (CPU temp, clock, etc.), it will flash every three seconds. This is an intended feature of newer firmwares, not an issue with your AIO. ->Thank you for contacting ASUS Support. My name is ___. and I will be happy to help you with your problem. I am writing this letter to update you on the current status of your current case. As recommended by our engineers, we have confirmed that this is a normal phenomenon, mainly to solve the problem of OLED printing caused by playing the same image for a long time.
