Need a Good Exhaust Fan!

So im looking for a 4" fan (if possible) that can push some air like 300 cfm +/-... I have everything set up on a 4" system right now but the inline fan that i have sucks major balls. Ive got a few 4" computer fans going but i need something that will suck all that hot air up and out of my room. Im looking for a good fan that is reasonably quiet and lasts for longer than a month... Cheap fucking Chinese shit! Any suggestions would be appreciated. Thanks!

u growing in what exactly?

get a ruck inline extractor. you would need a 5" diameter to extract 300+ m3 an hour though.
