Case Fans- Installation
The following steps will enable you to install a case fan. First, you must ensure that your PC is powered off before you install any component in your system. After opening the case, you will need a Phillips head screwdriver in order to remove/install case fans. If you’re replacing a fan, simply remove the old one by unscrewing it from the case and unplugging the cable from the header (or the MOLEX connection, if you have an older system). To mount the new fan, hold the fan up to the mounting position so that the holes for screws line up with the holes in the case. While holding the fan in place with one hand, with your other hand use four screws to secure it in place. Some models use plastic friction clips to hold the fan in place instead of screws. If the system is like this, simply un-snap the clips, remove the fan, and pop the new one in its place.
After you secure the fan, you need to attach the fan to an unused fan header to provide the fan with power. The headers are keyed to ensure a proper connection and prevent you from plugging them in backwards. Four-pin headers will work with three-pin fans, but you will not be able to control fan speeds, since this is only performed by the fourth pin in the connector.
When you are done installing the fan, make sure you route your fan and other cables using proper cable management techniques and some zip-ties. Proper cable management prevents the fans from hitting the cables when they spin and also aids in proper airflow to increase cooling efficiency. Be sure to power up the computer and make sure the fan is working properly.

In the lab exercise below, you should remove the old case fan and install a new case fan. Be sure to use proper safety precautions. For the purposes of this lab exercise, you can assume that ESD precautions are in place.
以下步驟將使您能夠安裝機箱風扇。首先,在安裝系統中的任何組件之前,必須確保已關閉PC的電源。打開機箱後,您將需要使用十字螺絲刀來拆卸/安裝機箱風扇。如果要更換風扇,只需將舊風扇從機箱中擰出並從插頭(或MOLEX連接,如果您使用舊系統)上拔下電纜,即可將其卸下。要安裝新風扇,請將風扇保持在安裝位置,以使螺釘孔與外殼上的孔對齊。一隻手將風扇固定到位,另一隻手用四顆螺釘將其固定到位。某些型號使用塑料摩擦夾而不是螺釘將風扇固定到位。如果系統是這樣的,只需取消卡扣,卸下風扇,
固定風扇後,需要將風扇連接到未使用的風扇接頭連接器上,以為風扇供電。標頭的鍵可確保正確連接,並防止您向後插入標頭。四針接頭連接器將與三針風扇一起使用,但是您將無法控制風扇速度,因為這只能由連接器中的第四針執行。
完成安裝風扇後,請確保使用適當的電纜管理技術和一些紮帶來布放風扇和其他電纜。正確的電纜管理可防止風扇在旋轉時撞到電纜,並有助於適當的氣流以提高冷卻效率。確保打開計算機電源,並確保風扇正常工作。

在下面的實驗練習中,您應該卸下舊的機箱風扇並安裝新的機箱風扇。確保使用適當的安全預防措施。在本實驗中,您可以假定已經採取了ESD預防措施。
