Hello Veky,
if you are searching pure performance leave the SP120 and go with the twister storm or NF-F12 3k rpm:

Scythe gentle typhoon 3 and 5.4k rpm are a good choice aswell if you can still found them.
rather if you want a balanced fan venturi, NF-F12, grand flex, twister pressure, silencio FP120 are all good choice, just check wich one will accomodate your needs better,
