Ok let's get dangerous...
In the case, if you're serious about cooling, you're going to have to make some modfications.
1> Cut out the grills where the fans mount to get a clean hole. A hole saw or just a pair of tin snips will do. Lay the case on it's side motherboard up and stuff the case with a beach towel. Cut slow and carefully. A loose bit of tin on the motherboard you fail to see when you power up and the game's over.
Do this on the back as well as the front. Don't forget the finger guards(add on grills).
2> Led fans are your choice but I use them so I don't have to listen for them. The leds on a fan get power from the same source as the blower part. Lights out and you can bet the fan's dead too.
High cfm or high speed equals noise, noise, noise. Shop carefully for fans. I have used Extreme Gamer and Mad Dog brands along with Antec. I no longer use Antec due to the propritary led thing they have going on but the fans are top drawer. Avg cost per fan>> $8.00USD
3> A fan controller is a must. Some come with temp probes and for the money do a good job. Cooler Master Aerogate II is one I use. Easy to install ands very informative. $39.00USD
4> Do this first before you go out and buy a bunch of junk you wind up not needing. Or cutting holes you can't fix. 120mm and 90mm and 92mm are costly. Why have to spend any more than you absolutly need to?
