Hello edoardo! 

You are giving us all heat sink envy!  Hahah.  But, as others have observed, the kit heat sink's are fine except in some unusual operations:
- more than 13v to the finals
- full power FT8 or WS
- zero free air movement. 

In 95% of cases, just drill some holes for air movement, and/or install a small & slow fan. 

I do 20v on the finals and WSPR 24/7 when I don't do psk/Hellschreiber.  And I use a fan on a thermal switch.
