Note: Most fans have small arrows embossed happening their frames that render the charge of air flow. When mounting, point the arrow towards the wrong of the computer for consumption, and the arrow towards the external for exhaust.
Power connections
Most cooling fans will connect to a PC with a basic connector of some sort. Modern systems will typically use 3-immobilise or 4-pin dedicated devotee headers, though standard MOLEX 4-pin peripheral connectors are also utilized.
From left to right: A 3-peg connector, a 4-pin connector and a MOLEX connector. Make sure to check what case of winnow connector you need before buying your winnow.
