Thanks to the advice of all of you, the problem has been solved.
In the end I bought an Artic Freezer 13, capable of dissipating 200W, starting from the base that my processor with overclocking is around 130W, there should not be a problem.
Said and done, just turning on the machine the first impression was good, reducing in vacuum a couple of degrees compared to the "factory" one of 95W.
The "fire" test was even better, with the micro at maximum load it did not exceed 56-57 degrees, thus lowering almost 15 degrees!!
Case closed, I just want to comment that the heatsink was around 30€, as you had commented, more than enough for this overclocking
Thanks to all!!
