Zorluk: KolayCPU Architecture Cooling and Sockets

A desktop technician is replacing a failed stock CPU heatsink with an upgraded thermal cooling unit. After removing the original heatsink, which of the following actions should the technician take before securing the new cooling unit to the processor?

  1. Clean the top of the processor with isopropyl alcohol and apply fresh thermal compoundCevap
  2. B
    Populate adjacent RAM slots to assist the new cooler with multi-channel thermal distribution
  3. C
    Upgrade the power supply unit to a higher wattage rating to offset the thermal dissipation load
  4. D
    Reconfigure the system storage drive from NVMe to M.2 SATA to lower central processing temperatures

Cevap

Clean the top of the processor with high-purity isopropyl alcohol to remove old thermal material, then apply a small amount of fresh thermal compound before mounting the new heatsink.
Whenever replacing a CPU cooler or heatsink, any existing thermal paste must be cleaned off the CPU heat spreader using high-purity isopropyl alcohol and a lint-free cloth. Fresh thermal paste must then be applied to eliminate air gaps between the CPU surface and the new heatsink base, ensuring effective heat conduction.

Adım Adım Çözüm

1
Inspect the CPU thermal surface
Residual thermal compound from the old heatsink is identified on the integrated heat spreader (IHS).
Old thermal paste degrades, dries out, and creates thermal barriers if reused.
2
Clean the surface thoroughly
The CPU heat spreader is wiped clean with isopropyl alcohol and a lint-free cloth.
Isopropyl alcohol cleans oils and residue without damaging electronic components.
3
Apply fresh thermal paste and mount the cooler
A pea-sized amount of thermal compound is applied, and the new heatsink is installed.
Fresh paste fills microscopic imperfections between the metal surfaces to ensure efficient heat transfer.
