Zorluk: OrtaCPU Architecture Cooling and Sockets

A desktop technician is assembling a high-performance workstation and configuring the CPU socket hardware along with a thermal cooling solution. Which of the following statements regarding CPU socket architectures and thermal cooling installation are correct? (Select TWO.)

  1. Land Grid Array (LGA) sockets feature pin contacts located inside the motherboard socket housing rather than on the processor package.Cevap
  2. Thermal paste is applied between the processor heat spreader and the cooler baseplate to fill microscopic gaps and improve heat transfer.Cevap
  3. C
    Ball Grid Array (BGA) processors utilize zero insertion force (ZIF) socket levers to simplify frequent end-user processor upgrades.
  4. D
    Pin Grid Array (PGA) sockets require installing cooling fan headers directly to CPU pins prior to clamping the processor.

Cevap

Land Grid Array (LGA) sockets feature pin contacts located inside the motherboard socket housing rather than on the processor package, and thermal paste is applied between the processor heat spreader and the cooler baseplate to fill microscopic gaps and improve heat transfer.
Land Grid Array (LGA) sockets place the delicate contact pins on the motherboard socket, requiring CPUs to have matching flat contact pads. Additionally, applying thermal paste between the CPU integrated heat spreader and the cooling block baseplate fills microscopic air gaps, ensuring maximum thermal conductivity.

Adım Adım Çözüm

1
Analyze CPU socket physical characteristics for LGA, PGA, and BGA packaging types.
Identify that LGA sockets put pins on the motherboard socket and pads on the CPU, whereas BGA CPUs are soldered and PGA CPUs have pins on the chip package.
Understanding socket mechanical construction is essential for safe handling during installation.
2
Evaluate thermal management components and proper thermal compound placement.
Confirm that thermal paste eliminates air pockets between the processor IHS and the cooling block.
Air is a poor thermal conductor; thermal paste ensures efficient heat conduction to preventing thermal throttling.
