A field technician is assembling a desktop computer using a Pin Grid Array (PGA) processor and an active cooling system. Which of the following statements accurately describe the physical installation and operational characteristics of these components? (Select TWO.)
- The processor pins must align with the motherboard receptacle holes and seat completely with zero downward force before securing the retention lever.Cevap
- BVertical pressure must be firmly applied to the top of the processor package while closing the socket arm to ensure the pins punch through the socket foil.
- Connecting the cooling fan to a 4-pin header on the motherboard enables Pulse Width Modulation (PWM) for dynamic fan speed adjustments based on system temperature.Cevap
- DSystem RAM modules must be installed in adjacent slots directly contacting the processor heat sink to dissipate memory controller heat.
Cevap
The correct statements are that PGA processors require zero insertion force with pins aligned to socket holes before locking the retention lever, and that 4-pin CPU fan headers provide PWM signal control for automated variable fan speeds.
PGA processors use Zero Insertion Force (ZIF) sockets where the CPU drops smoothly into place without pressing, and the side lever is locked down to clamp the pins. Additionally, 4-pin motherboard headers supply a dedicated Pulse Width Modulation (PWM) signal line that enables automatic fan speed scaling according to CPU heat output.
