| My arctic cooler randomly turned off today while i was playing a game and it caused my cpu to overheat and shut down. I tried seating the cables and checking bios but the cpu fan in bios says none detected. I had a similar issue a few months ago but was able to fix it but switching which cable was in which slot. it is a Arctic Liquid Freezer II 240 connected to my ASRock X570 PG Velocita ATX AM4 Motherboard. Any ideas or help would be great. |

Is it the fans or the pump not being detected? Have you tried connecting a regular case fan to the same header/s to see if that works? If a normal fan spins up then you may have a dying/faulty AIO. -------------

"I had a similar issue a few months ago but was able to fix it but switching which cable was in which slot." By, "switching," do you mean that you moved the AIO's connector to another one on the motherboard? If so, did you test the original one on the motherboard with another fan or something? Or if you switched with another fan and both still work? If the AIO is pulling too much current from the fan/water-pump header, bad things can happen. At best, motherboard might be smart enough to just shut off the power to it, but at worst, it might fry something on the motherboard. Based on the limited information I got so far, that is my guess. Something in the AIO went bad (one or more fans, or more likely the water pump), and is pulling too much current. Their spec says the whole thing will only pull 2.7 watts at most (only 225mA), which should be perfectly safe under normal circumstances, but if something goes bad in there, and it pulls too much current, it can damage the motherboard circuit. I think most of these fan/water-pump connectors are designed for max 1A. If the motherboard connectors are still working, then maybe it has a built-in protection mechanism. Either way, it could be as simple as broken/internally-frayed cable, or as bad as fans/pump on their last legs. |
