Socket 775 Processors (Cont.)
The cooler must be aligned to the four holes located on the motherboard.
After putting the cooler over the processor, you should “close” all the cooler locks by using a screwdriver. Observe Figure 38 to know the correct position. The arrow must face the outer side and the notch of the white part must touch the black support.
You should press the locks two-by-two, diagonally.
It’s very important to check if the cooler really is well-installed and if all the locks are in the correct position.
