Ok, (bear with me I'm not very hardware knowledgable) I've looked just about everywhere but no one can seem to give me a straight answer to this question. I have an Alienware Aurora R3 Desktop. In it, there is a liquid cooler (which I cannot seem to find a name for anywhere or online) and I want to get a better one to replace it. Are there possible compatibility issues (will only certain liquid coolers work with my computer) or can I use just about any liquid cooling system. If there are compatibility requirements, what are they? I just upgraded from an i5 to an i7 2600k, and my idle temps are around 45-50C, and I want it to be idle under 35C.
