It's been a long time since I last posted on this forum but this has been stumping me as of late. I have a Thermaltake Water 2.0 Performer liquid cooling loop for a while and lately they have been acting up. I noticed that my temperatures on idle could sometimes go up as high as 80 celcius, which is absolutely not right. This happened after I serviced my machine, and I think I bumped the liquid cooling around in the process of it. I noticed however, if I keep knocking my radiator on the side, the reported temperatures get cooler, and I notice that I can feel the hot air being dissipated from the fins (previously cool). The thing though is that after leaving it for a while again, the fins don't seem to dissipate anything, and the cpu temps start rising again. I have a feeling that there are air bubbles getting stuck in the loop somewhere, but I have no idea how to get them out or at least out of the way in a closed loop. Anyone have any suggestions/ideas?
