1:CPU
1:PSU
1:Side intake fan
1:ATI HD5750 fan

Total: 7 fan

Chassis:
2x Front intake Silverstone AP121
1x Side intake Thermaltake 230mm
1x Back exhaust Thermaltake 140mm
1x Top exhaust Thermaltake 200mm
1x Heatsink's fan Cooler Master Blademaster 120mm
1x PSU's fan (Gigabyte Odin Pro 550W, 120mm PWM)
2x GPU's fan (Gigabyte GTX560 Ti, 80mm PWM)

9 Fans total.
Front intake were changed from original Thermaltake 200mm for better airflow.
Best to use 180mm and above fan, or if possible 120mm at the very least to give more airflow and at the same time much silent.

My 24/7 download server has recently changed its PSU fan from 2x 80mm to 1x 120mm (DIY PSU case mod) to reduce the noise, the 2 units of 80mm's hydraulic bearing were making cranking noise.

makaih... 8 fan total, banyak jugak... anyway i want to ask something, do we need more powerful psu if using more fans ?

here's it:

2 x front case for hdd
5 x wc radiator (2 x intake / 3 x outake)
1 x exhaust fan
1 x psu unit
2 x ram

= 11 fans. gpu doesn't have fans since it's on watercooling.

Main rig, i5 2500K HAF-912

1x 200mm intake
1x 200mm top fan exhaust
1x 120mm exhaust
1x 120mm side panel intake fan

1x 120mm bottom mount PSU fan
1x 120mm hyper 212+

1x top mount PSU fan (12cm type)
1x D.I.Y chipset fan. (I screw a 50mm cpu fan on top of the ori non-fan heatsink.)

total 9 fans
this second rig quite noisy, cause the 80mm/60mm fans are high speed 4000 -5000rpm type.

140mm = 2 x top exhaust

120mm = 1 x rear exhaust, 1 x front intake, 1 x side intake, 2 x bottom intake

80mm = 1 x side exhaust

CPU X 1
GPU X 2
RAM x 1
PSU X 1

Total = 13
