Excellent AIO coolers, both come with an RGB controller for synched effects. I never plugged the RGB in and I cannot tell you how great it looks. If it is similar to the XG memory then it looks awesome. I just want to tell you about the performance from the DX 360 on my OC Lab chip.
I was able to bench light threaded without Hyperthreading at 5.5Ghz all day long, I had to drop back to 5.4Ghz with hyperthreading and 5.3Ghz for heavy threaded loads. I cannot guarantee your mileage will be the same but this AIO stood out on my bench for setting up and memory testing.
I am very familiar with these AIO's and the previous generations and much has not changed. Flexibility of the water lines is important to me and not having force the lines into position is critical to its function. Thermaltake has done well in providing the needed clearances and line distance for most scenarios. Another thing to watch out for is side clearance on some coolers that interfere with memory slots or stock heat sinks. These coolers avoid those issues.
