I'd suggest some of the 1200 RPM slipstreams, they're amazing case fans, move a ton of air, they just shouldn't be used on heatsinks or rads.

EDIT:
1200 RPM, nice and quiet http://www.newegg.com/Product/Produc...82E16835185058
1900 RPM, overwhelmingly noisy at times http://www.newegg.com/Product/Produc...82E16835185060
1600 RPM, a good balance IMO, I run my 1900RPM's at 1550RPM and they're nice and quiet http://www.newegg.com/Product/Produc...82E16835185059

Open the side case door, that will help dramitically reduce case and ambient temps.. gl

These fans are very good http://www.newegg.com/Product/Produc...82E16835233009. They are silent but the vibrate so you just need to get a vibration dampener to make even quieter

Get those S-flex fans for sure. And yes, the slipstreams are low quality crap compared to an S-flex.

As for the blue LED fan, that narrows options a bit. There's always the blue LED yate loons, but they do use a sleeve bearing.

OK S flex it is even tho those Xigmateks are tempting. The B- gears use sleeve bearings tho too. and my side panel is modders mesh except for hte edges so its like having the side panel off.

I'm pretty sure that S flex fans don't use sleeves. That's what makes them actually good, unlike the slipstreams.

I've been using the same slipstreams through two builds and over a year and a half, they're still going, running 24/7. Yeah, they're lighter and ultimately much cheaper in quality than the S-Flex, but they're also significantly cheaper. $9 for a fan that's lasted me a year and a half is an absolute steal, even if they died tomorrow I'd be incredibly pleased with my purchase. I would absolutely by another 6 of them.

But with an S flex, it'll last way more than a year. So you're saying that you'd rather buy a $9 fan every year, instead of a $20 fan every 5 years?

Doing this can actually defeat the purpose of having good airflow. You want the side panel closed so that your case's fans can do their job of maintaining airflow.

Think of it as running a fan with no duct(outside case around blades) and running a normal fan with the duct. The fan blades without airflow direction are going to pull in air from almost all sides and exhaust the air out from most sides, reducing the actual amount/volume of air being moved due to the lack of pressure of the air being moved.

Same as with the airflow of a PC case...The volume of cool, fresh air being pulled into the case by the intake fans(along with all air within the case) will radiate out of the open side panel, reducing the overall volume of hot air for the exhaust fans to expel, therefor cutting down the speed and amount/volume of air being pulled into and pushed out of the case.

A closed case, in theory, raises the pressure of the air inside, which allows the exhaust fans to exhaust more air as the air is 'squeezed' into a smaller area(higher air pressure). An open case will also cause the exhaust fans to not only move air from inside the case, but they will also move the air from outside the open panel which defeats the airflow design and lowers the efficiency.

Blue 2 pack for $10 40CFM @ 19dB
http://www.newegg.com/Product/Produc...82E16835103022

I have them and they're nice and quiet. I have all coolmaster 120mm fans(3 blue, 2 non LED) and keeps everything in my case cool while being quiet. I game around 42C @ 3.4GHz

I wish there were blue led fans with on/off switches for the lights.

Get normal fans and CCFL's. That's the choice I had to make

Noctua NF-P12
High static pressure per dB and good CFM.

No problem man. Yeah..those noctua fans don't have any static pressure. When i was doing my heatsink tests, so little air came through the heatsink with that fan that the VRMs on the mobo got no airflow over them. Got so hot they started to smell bad, and this is with aftermarket cooling on them.

That's the route I am taking now. It was hard.
