Hey guys! So I have a Corsair H50 cpu water cooler that has been running flawlessly ever since I got it about 6 years ago. However, recently, it has been getting noisy like I can hear the water circulating through the loop and it does not sound like things are running smoothly in there like it used to. I was just wondering what you guys think is going on and if I should replace it or if it will just be a simple fix like adding more water to the loop potentially. Never had any issues with it, never had any leaks and has all around been a great cooler. Please let me know! Thanks!
