i have had my alphcooler for approx 2-3 months and it started making a noise but would eventually pump water but now it continually makes the noise and GPU temps go into the 100's.. i took it out of comp, did not seem like the pump was working anymore. . it is a rtx 2080. i was trying to attached a video but it is a .mov file and that is not supported here,,, i guess... the noise is like a quack ,,, yes like a duck...
