I have a Dan a4 case with Asetek 645LT cooling a 10700k with losercard mod. It's been quiet since I've built it back in November but ever since I've been more mobile with it, traveling and working overseas, it's starting to make a buzzing noise. I'm pretty sure it's air in the pump because after moving it around it disappears and comes back. But it's weird because when I load up a game the buzz goes away.
