70cfm also ok what... cheap fan. u pay peanuts u get monkey la. the issue that they put wrong claim is, maybe because they measure the cfm by putting the 120mm fan spinning in front of a table fan, so the fan's real output + kipas meja = 90cfm.

joke2 abit dun flame me ya~

busta_dude selling a delta gila kipas 190cfm... the *thingie behind the blade* (dunno what to call em) is curved as to create turbulence, hence the extra high cfm and extra excruciatingly annoying whining (or whooshing? u decide) sound.

btw, i got 2 of those 90cfm fans. and i feel i need another one...
