[SOLVED] Don't know how to remove my CPU Cooler from my motherboard.

As a suggestion:
Before removing the cooler, run the cpu a bit to heat up and soften the thermal paste.
That makes it easy to unstick the cooler from the processor.
Do not remove the processor from the socket once it is in.
It is too easy to damage socket pins.
They are delicate and are only certified for 15 insertions.
 
Those nuts require some odd tool to screw off, do you have any idea of what I need to do so?
Those nuts are placed wrong side up. If they were placed correctly, you'd be able to use flat screwdriver, to take them off.

Now - you'll have to use pliers instead.
