somebody told me that 5 blade fan use the same motor of 3 blade fan. so it will slow the fan rotation and eventually slow the cooling effect but, they are wrong.

but, I bought 5 blade & 5 speed KDK fan, 2 days ago, install it myself. got electrocuted once haha...

cooling effect is fast too. (only use speed no.2)
