high temps

The new temperatures are better but still a bit high for a non overclocked processor, for example my 4790k overclocked to 4.7GHz and at 1.300v feeding the CPU, temperatures will hit about 65-75c degrees over a 15 minute stress test. With the radiator in the front with 2 fans pulling air in and one fan pushing air in you have the best possible cooling flowing across the radiator, so putting the radiator on top will not improve temperatures.

Unfortunately, from the way things are looking it seems as though your pump/waterblock over the cpu is the likely culprit. Modern intel processors use a very high mounting pressure to squeeze the cooler/waterblock against the processor for the best possible heat transfer. It appears that the mounting pressure could be too low, it is an issue i had with my own h100i and i've read quite a few forum posts across the internet with others having the same issue.

It may mean that a RMA could be the best route to correct the problem.

I have heard others recommend applying additional pressure to the pump block while performing the stress test to simulate increased mounting pressure and see if the temperatures would drop at all while pushing on the pump, this would require a rather hard press down on the block and motherboard and I wouldn't personally recommend it for fear of causing mobo damage.

Also remember that a stress test is designed to produce a worst case scenario for cpu loading, even the most demanding games will likely not produce temperatures that high. I cannot speak to what type of load some professional programs may produce but those situations would still be no worse than what a stress test will produce.

In the end, you've seen some improvement, if you're happy with the temps then you may be set, keep in mind that intel haswell cpu's will only start to throttle when they hit around 100c(Please correct me if i'm wrong here). However keeping temperatures as low as possible is always advisable.
