question about 360's rear exhaust fans

it appears that one of my fans is not working. when placing my hands at the back, i can only feel air coming out from the right side... is that the way the fans are supposed to work? or should i feel air coming out the entire ventilation holes at the back?

opinions pls...

oh ok, so the system would probably not run if one of my fans is not working.. thanks guys.. one more question... are you guys using 3rd party fans (eg. nyko intercooler)? would you recommend such accessory? SuperPogi

I wouldn't waist your money on any third party cooling devices. I'm 100% positive that the 2x 80mm rear fans cool our 360's just fine. Just remember do not keep your 360 on carpet the carpet tends to insolate heat. I keep mine a glass shelf on my TV stand where it get's plenty of room to breath. NeoNavarro
