So... i forgot to plug in my AIO for about 10 minutes and the CPU was at 100 degrees the whole time. Afterwards it still works perfectly except it now makes some bubbling noises that werent there before; it actually sounds more like bubbles getting sucked into a tiny propeller.

Solution
Air in the pump. You'll need to drop the pump below the level of the inlet tubing of the radiator, so pretty much just tilt the pc on its rear and let it run for a while.
