A worthy note:
I have a unique way of applying my thermal paste. I wish took a video or a picture. I used Artic Silver 5- I spread it evenly to totally cover the cooler on the exact area it contacts the CPU.
I once had overheating issue on a 2500k machine- so I re-did it and saw amazing improvement. I have been doing it that way ever since and my systems seem to run cool even when I beat on them.
Having a Cosmos II case I am sure helps too. The case is just plain awesome. Its the quietest case I've ever owned, and also the coolest.
I'm looking at a good water cooler - or some type of liquid radiator but I have just begun exploring my options. The Cosmos II has some fit issues if I recall - so I will have to do some good research but I think that might help me go hard.
I generally don't like to overclock and push a brand new CPU generation until I have seen some feedback. I am not into being a test bed myself. With the 4770k I have honestly done zero reading on the results so I have no clue where I can go with it or what others have seen yet. That is my hesitation with pushing this thing.
I ran the XS test (but I have no clue what it does or what it means... lol )
A couple clicks and I beat the high score. (do I win a prize? )
