I have just overclocked my 2500k to 4.4ghz with the vcore set to 1.35v
My load temps hit 73'c using the Corsair Hydro H100i.
This can't be right can it, i was expecting to to be lower.

They certainly don't look kinked. From the rad to the block there is a nice smooth curve of tube.maybe check to see if the pipes are kinked?
I'm getting the same temps. The radiator temp doesn't seem to go above 35 even after a warm run.
I'm going to take another look at the paste soon but I was also expecting a much colder block.
