This morning it was fine, but it's happening again, HWInfro reports 57.3°C coolant temp. Is it possible that there's something in the loop, like a bubble, but the CPU temps are fine? My 3600 is idling at 35°C. I don't know how scientific it is, but I touched the radiator, tubes, and the CPU block, and it doesn't feel like it's trying to sweat out ~60°C anywhere. If there's blockage, and the liquid isn't getting circulated, I could understand that the radiator doesn't have anything to work with, but then shouldn't the rest of the assembly be hot somewhere?

My H100i RGB Platinum is raising concerns. While basically doing nothing, other than typing this out, the coolant temps are at 58°C. Pump is chugging along at the usual 2.3k RPM, fans are at 1.5k RPM. CPU (R5 3600) is not hot at all, jumps up to low 40 every now and then. Room is the usual 25-26C. Everything seems to be in order, except for the coolant temp. It used to be in the mid-high 30s. I don't use iCUE, and the last time I did, I turned off all the LEDs, because I read that they trip up the temp sensor. The last change I did was to flip the front mounted radiator so the tubes are on the bottom and not top, but this was also a few weeks back. Weirdly, as I was typing this out, and had the air conditioner on for a couple of minutes, the coolant temp suddenly dropped to 33°C. The room didn't get 20C cooler suddenly for this behavior to make sense. What can cause this issue? A new cooler (NH-D15) is arriving tomorrow, so it's not terribly crucial that I do something about it (as long as it doesn't suddenly blow up), but I'd like to know what the issue is.
