I can't make smaller pins than with 1.5mm mill. Because it takes more time, with smaller tool. For me I think the 1.5mm tool is limit. That is why I can't male that small pins like at nexxxos xp or eaven hp.
Anyway Swiftech MCW6002 has bigger pins than nexxxos.
Swiftech has 9mm high pins and 5mm thick base. The only thing that bothers me is base thickness. For my opinion it si way too much... Although I am not sure if the picture shows real base thickness. I know that antarctica has 1.4mm thick base, and nexxxos about 1mm i guess. Of course swiftech should have more thick base because the heat must spread to bigger area...
that is for now...
