how many ppl run a switch to there fan so they can turn it on whenever? i know ive read it where a couple ppl do this, would you guys suggest this?

also- im running a dual core half radiator right now with a stock oem fan, should i upgrade to a slim fan or will the oem be fine?

 

Hook it up to a fuse/switch/fan
My bro has it on his car. Sucks, when you forget to switch it on. OVER HEAT!
Also if you let someone borrow it and they don't know... OVER HEAT!
