I have an alienware aurora r4. When I bought this it said it came with a liquid cooling unit, standard for auroras I think. I was just wondering if any maintenance needs to be done to keep it working right. I'm planning to completely clean my computer this weekend so if I have to do anything I'd like to know. I'd also like to know what exactly I would need to do, assuming I need to do anything. I've never used liquid cooling before.
