First thanks for your quick reply!

As many people said, I will go for the Cooper 9500 block.

Little question: If my memory is already at 50 deg and at 60 deg on high load, do you recommand to change the heatsink for cooper one?
Afther 3 year on use, that's could be a good idea since I could easely reuse it.
Any Comment?

L1 Data : 8 Kbytes
