Take care not to scrape the motherboard surface when mounting a clampstyle processor fan, or else damage may occur. When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or damage may occur! Do not neglect to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your Socket 478 processor or else boot-up may not be possible. Socket 478 processors provide internal thermal sensing: a socket mounted thermal resistor is not needed. 2.4.3 Installing the heatsink and fan The Intel® Pentium4™ 478 Processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. When you buy a boxed Intel Pentium 4™ 478 Processor, the package includes the heatsink, fan, and retention mechanism. In case you buy a CPU separately, make sure that you use only Intel certified heatsink and fan. Follow these steps to install the CPU heatsink and fan. 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base. The retention module base is already installed on the motherboard upon purchase. You do not have to remove the retention module base when installing the CPU or installing other motherboard components. Your boxed Intel Pentium 4™ 478 Processor package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter. 2-6 Chapter 2: Hardware information

2.4.3
Installing the heatsink and fan
The Intel
®
Pentium4™ 478 Processor requires a specially designed
heatsink and fan assembly to ensure optimum thermal condition and
performance.
The retention module base is already installed on the motherboard
upon purchase.
You do not have to remove the retention module base
when installing the CPU or installing other motherboard components.
Follow these steps to install the CPU heatsink and fan.
1.
Place the heatsink on top of the installed CPU, making sure that the
heatsink fits properly on the retention module base.
When you buy a boxed Intel Pentium 4™ 478 Processor, the package
includes the heatsink, fan, and retention mechanism.
In case you buy a CPU separately, make sure that you use only Intel
certified heatsink and fan.
Your boxed Intel Pentium 4™ 478 Processor package should come
with installation instructions for the CPU, heatsink, and the retention
mechanism. If the instructions in this section do not match the CPU
documentation, follow the latter.
Do not neglect to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket
478 processor or else boot-up may not be possible. Socket 478 processors
provide internal thermal sensing: a socket mounted thermal resistor is
not needed.
Take care not to scrape the motherboard surface when mounting a clamp-
style processor fan, or else damage may occur.
When mounting a
heatsink onto your CPU, make sure that exposed CPU capacitors do not
touch the heatsink, or damage may occur!
