My advise is unplug the top intakes.
Maybe use the back top vent as exhaust with front top blank or even closed off.

So, I have good news. I've bought an extra fan, 1500 RPM from Fractal Design.
I installed it as an exhaust fan on the back of the case to replace the original 1000RMP fan that came with the case.
This original 1000RMP fan I installed it in the front as a second intake fan.
So now I have 2 x 1000RPM in-taking fans and one 1500RMP exhaust fan located just in front of the Noctua CPU cooler.
This way I managed to reduce my temps by 10-15C. Unbelievable.
I managed easily to OC my rig up to 4.7GHz and after 1h of testing I get the following temps:
Max Core0 = 73C
Max Core1 = 70C
Max Core2 = 71C
Max Core3 = 68C
This is not worrying my anymore.
Always my Core0 was 5C higher than the coldest core. Any idea why, Is this happening fore most of you?
BTW I'm an IT guys working in this field for many years, but never bother to OC my home rig so far.
In conclusion I underestimated the role of case fans, I though mostly the CPU coolers are important.
Thanks to your recommendations guys, I managed to reach my Everest 4.7GHz at decent temps.
Don't want to push more to get in the end just a few msec. better performance in Lightroom.
From now on, for everyday work, I will go back to more terrestrial values like 4.6GHz, and leave it like that for the rest of it's life.
Thanks again and happy OC
