English 1-3 Installation of the CPU and Heatsink Before installing the CPU, please comply with the following conditions: 1. Please make sure that the motherboard supports the CPU. 2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong direction, the CPU will not insert properly. If this occurs, please change the insert direction of the CPU. 3. Please add an even layer of heat sink paste between the CPU and heatsink. 4.
Male Push Pin The top of Female Push Pin Female Push Pin Fig.1 Please apply an even layer of heatsink paste on the surface of the installed CPU. Fig. 2 (Turning the push pin along the direction of arrow is to remove the heatsink, on the contrary, is to install.) Please note the direction of arrow sign on the male push pin doesn't face inwards before installation. (This instruction is only for Intel boxed fan) Fig.
English 1-4 Installing/Removing Cool-Plus (Northbridge Cooling Fan) Fig.1 To attach Cool-Plus to a heatsink, align the extensions on both sides with the grooves in the heatsink as shown. Firmly press down until it snaps into position. Fig.2 Once the fan is properly affixed onto the heatsink, plug the power cable into the NB_FAN connector. Fig.3 Before proceeding, first check to make sure that the fan's power cable is disconnected.
Fig.2 Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module. Reverse the installation steps when you wish to remove the DIMM module.
