Corsair H110i Water Cooling

[ZED]

So, I had this amazing moment today when Amazon knocked on my doors and delivered my new water cooler Corsair H110i.

I had DeepCool Captain 120 for a year now and after it had a hiccup 2 days ago I decided to finally get a new water cooler and go with 280mm rad instead of 120mm.
With DeepCool I was able to overclock my i5 6600k to 4.2 Ghz and keep temperatures around or below 60C at full load.

If anyone has i5 6600k and Corsair H110i, how far did you go in overclocking with this cooler?

I hope I made the right choice. I was thinking about x61 Kraken at first but then changed my mind and went with Corsair H110i.
