Just built out an i7-4770K on an ASUS Z87-Pro. Used Corsair H80i cooler. It has two Radeon 7750 cards. Front intake fan, rear intake fans on either side of the radiator, and two fans exhaust out of the top.
When I overclock this to 4.0GHz from the 3.5GHz stock, it pushes about 95 Celsius when doing a stress test that lasts about 5 minutes.
Now, I am running quiet mode on the H80i, but even when I change it to max fan, it will still max out about 85-90 celsius. This seems too hot to me for the minimal OC'ing I'm doing. The case is not streamlined on the inside really because there's just nowhere to put these cables (it's a Corsair 200R and not designed for extreme stuff), but I have zip-tied the cables and there seems to be decent airflow. 75 degrees I can understand--but 90?
When i installed the H80i, I did my best to ensure smooth, even contact with the CPU--the h80i came with thermal paste on it, and so this should not be an issue. I know haswells run hotter than their predecessors, but c'mon...
I run my rigs on a custom tray (not a case) open air, easy to do work on and they are stackable.

I've always thought about overclocking and water cooling but never gotten around to it; neon lights is as far as I've gone . Thought the water cooling would bring down the temp considerably. These are my temps with the stock i7-4770K:

Maybe a bad contact between the rad and the cpu, bad or no thermic grease.
I setup for one of my kids friend a PC with the parts I was using 5 or 6 years ago, a dual Opteron dual cores, 2.4 Ghz. With basic rads the temp was around 72°C during stress tests, which is very hot but normal according to this kind of old processors, fan type and case size, but 95°C on an i7-4770k, something is wrong!
Like wrote previously, the good test to be done is to check the cpu and the mobo T° with cpu idle, then with the stock frequency during a stress test, and then overclocked.
