3.5 Cooling the System Flashcards
What is the primary purpose of cooling in computer systems?
To dissipate heat generated by components and prevent damage or performance degradation.
What is passive cooling, and how does it work?
Passive cooling uses components like heat sinks without moving parts to dissipate heat by increasing surface area for natural cooling.
What is thermal paste, and why is it used?
Thermal paste eliminates air gaps between the CPU and heat sink, ensuring efficient heat transfer.
What is active cooling, and how does it differ from passive cooling?
Active cooling uses fans to increase airflow and actively dissipate heat, unlike passive cooling, which relies on heat dissipation without moving parts.
Where are cooling fans commonly used in a computer?
On CPUs, GPUs, power supplies, and inside the case to maintain proper airflow and dissipate heat.
Why is dust buildup on cooling fans problematic?
Dust can slow down or break fans, reducing airflow and cooling efficiency.
What is the best practice for maintaining cooling fans?
Clean fans and remove dust buildup every 3 to 6 months to ensure efficient operation.
How should thermal paste be applied during CPU installation?
Apply a pea-sized amount of thermal paste on the CPU, then press the heat sink down to spread it evenly.
What role do case fans play in system cooling?
Case fans help expel hot air from the case and bring in cooler air to maintain optimal airflow.
What is the process of installing cooling components for a CPU?
Install the CPU in the socket, apply thermal paste, attach the heat sink, and secure the CPU fan for active cooling.
What is the advantage of combining passive and active cooling methods?
Combining passive heat sinks with active fans enhances heat dissipation by increasing surface area and airflow.
How does a heat sink function as a passive cooling component?
A heat sink increases surface area to dissipate heat naturally through convection.
Why are fans included in power supplies?
To cool the internal components of the PSU and expel heat generated during power conversion.
What is the primary cooling method for high-performance graphics cards?
Active cooling with dedicated fans to dissipate heat generated by the GPU.
What should you consider when managing airflow in a computer case?
Proper alignment of intake and exhaust fans to ensure hot air is expelled and cool air circulates.
