5. Frequently Asked Questions
Q: What will be the impact if the fan is installed upside down?
A: It will cause disordered air ducts, reduce heat dissipation efficiency by more than 30%, and may cause hardware overheating in the long term.
Q: How to determine the air inlet direction of the fan?
A: Usually the fan frame side is the air outlet direction, and the convex surface of the fan blade is the air inlet direction. You can also observe the position of the support bracket. Most fan support brackets are on the air outlet side.
Q: How many fans need to be installed in the chassis?
A: 3-5 are recommended for ordinary mid-tower chassis (x2 for forward, x1 for rear, and x1-2 for ejection). The details need to be adjusted according to the heat generated by the hardware.
Through the above structured guide, I believe you have mastered the key points of installing a cooling fan. Reasonable installation of fans can not only improve heat dissipation efficiency, but also extend the service life of hardware.
