i have a thermaltake water 3.0 since around 2014, or should be around that, but since a couple of hours ago, when i was switching fans to a "silent" one the watercooler temp got really high (70c in bios) easily reaches 93c and shut itself, and all of this is in the bios, i switched back to my delta fan and it still overheats, i replug the connections and still, oddly high temps, even on stock settings (X4 760K) and shut down due to overheat, then i changed to the stock cooler and it hovers normally at 45c at the same config, so... is my cooler busted or something else ?

Final Edit: i did another swap and tested it, it seems to work just fine now, dont know what caused it in the first place, but now its working as its supposed to be, thanks for the suggestions anyway
