Get Xtraflo from flipakrt or local amrket. Both are same fan. One is with Red LED and another version - without any LED. There is another xtraflo version available, but not in Indian market which have blue LED.
Yes it is. I took it apart from my Evo and put it as rear exhaust. I have some cougar vortex fans. 2 of them I use with hyper 212 evo.
Now if you say how I got vortex fans, I would say I got it via my relatives living in US.
