Case Fans in Lebanon.

How many fans do you need?

Most gaming builds want at least three fans: two or three pulling cool air in at the front or bottom and one pushing warm air out at the rear or top. Powerful builds with a high-end graphics card and processor benefit from more. The builder adds up the fans that come with your case, the fans on your liquid cooler's radiator and any extras, and compares them with the mounts available.

120 mm or 140 mm?

120 mm fans fit almost every case and radiator. 140 mm fans move more air at lower speed, so they can run quieter, but check that your case and radiator support them. Thermaltake EX14 and CT140, SWAFAN GT14 and the slim Thermalright TL-B14015 come in 140 mm.

Reverse-blade fans

Reverse-blade fans show their clean side while blowing the other way, so a bottom or side intake looks the same as the rest. They are made for glass cases such as the Lian Li O11 range: look for Lian Li reverse models and Thermalright TL-C12R and TL-S12R.

Lighting, control and cables

• ARGB: addressable lighting synced through your motherboard's 3-pin 5 V header.
• Daisy-chain fans: Lian Li UNI FANs link together so one cable runs a whole row.
• Wireless: Lian Li wireless UNI FANs reduce the cables between fans and controller.
• LCD fans: Lian Li TL LCD and SL Wireless LCD fans add a screen to each hub.
• PWM: four-pin fans let the motherboard adjust speed with temperature.

Running out of headers? A fan and ARGB hub from PC build accessories connects many fans to one header. The builder flags when your build has more fans and pumps than the board's fan headers.

Fan direction and pressure

Each fan has arrows on the frame showing airflow and rotation. Aim for slightly more intake than exhaust, so the case stays under positive pressure and pulls air in through the dust filters. Fans on radiators and behind dense mesh benefit from higher static pressure models.
