tuniq 2 has fan built in. Has many cons for it.
*cant upgrade to HP fans like delta/kaze ultra etc.
*cleaning will be pita
*only one fan support
mugen 2 can have two fans, and you can have two hp fans on it, say 2* slipstream 1900/ST FM121 110 cfm if u want em to be silent, or 2* kaze ultra 133 cfm if looking for ultimate performance irrespective of noise.
mugen 2's fin gap being bit wider than venomousX or TRUE, ll work well with low static pressure fans like slip stream 1900/FM 121 etc.
TE official dealer Phoenix is selling mugen 2 for 3k. It comes bundled with all mounting brackets, backplate and a slip stream 1600 fan. ask him to exchange it with 1900 one before shipping, and maybe get another one too.
u cant get a better cooler @ 3.5k than the mugen 2+ 2* SS 1900. check its reviews.
