Hi everyone, i have a CORSAIR iCUE H100i ELITE LCD XT RGB CPU Cooler, and i am hearing this buzzing sound in my PC.

It has been cropping up occasionally since i got the PC, and i am not sure if it's a fan or if it's the pump failing.

The reason i think it could be the pump is my liquid temperature in the cooler has skyrocketed over the last two years. It used to be at about 37c while gaming, and now it gets up to 50c, sometimes 51c. In this video i just had balatro running and the liquid was way up at 43c. Doesn't seem right.

My CPU temps themselves don't seem to go past 85c really under heavy load, but it still runs quite hot.

Does anyone know what this could be?
