The air circulation in the PC is essential to avoid overheating which could damage the circuits. Here’s how to position the fans optimally.
When you build your own PC, you need to install fans to circulate the air in the case. But you shouldn’t get it wrong because the fan sucks in air from one side and blows it out from the other side. It is therefore essential to find the right orientation.
- Look closely at both sides of the fan. Usually, one side has a frame that protects the blades. It is from this side that the air is expelled.
- Some fans have arrows on the edge that indicate the direction of air flow.
- If your PC has a “water cooling” type cooling system with a radiator, attach the fans so that they suck air into the case and expel it to the radiator to evacuate its heat.
- If your PC uses fans on the front and back of the case, the front fans should suck in cool air from the outside, and the rear fans should expel hot air to the outside.
- Feel free to experiment with different positions for each fan, rotating them, to find the best one based on their power cables.
