Pros: Quiet pump, many LED color options, simple software, looks great.
Cons: Fans rattle and are generally loud when above 50%, sometimes I hear air bubble noises, lower performance than expected.
With my air cooler I my system ran at: 34C idle, 62C load
With the X60 my system ran at: 42C idle, 63C load
For these tests I ran the X60 so it had similar loudness as my air cooler, for load I ran prime95 for 3 minutes (no long I know). For the temperature readings I used CPUID Hardware Monitor CPUTIN temperature.
I really expected more out of this cooler, perhaps it is just faulty or I did something wrong. When I first put it on with the stock TIM the temperatures were terrible (50C-ish idle), so I got arctic silver 5 and now it runs at 42C idle as stated above. I don't really know what to say about weather or not I'd recommend the X60 to anyone. My bad experience has somewhat clouded my judgment. I'll still use the cooler because I have hope that it will someday work properly.
