Which of the following processor features is MOST likely to dynamically reduce power consumption based on current operating conditions?
You have a system that has been overheating. Which of the following actions will NOT help to keep the system cool?
Removing the case side panel.
Explanation: The system case is specially designed to maximize air flow across system components. By removing the side panel, you modify the air flow path and reduce its effectiveness. In addition, removing the side panel allows more dust to accumulate. Dust acts as an insulator and traps heat close to components. Cleaning off the inside of the computer case, installing heat spreaders and heat sinks on internal components, installing a water cooling system, and adding thermal paste between CPU and heat sink are all good ways to keep the system cool
What is the correct order for installing a processor for proper cooling?
CPU, thermal paste, heat sink, fan
Which of the following thermal solutions might you find on memory modules?
Passive heat sink
Match the cooling system types on the left with the appropriate characteristics and uses on the right. Each cooling system type can be used once, more than once, or not at all
Active heat sink:
- Used for cooling high-end video cards
- Has a fan attached to the heat sink
- Used for cooling CPUs
- Used for cooling high-end gaming computers
- Used for cooling high-performance systems
Passive heat sink:
- Used for cooling memory modules
- Has no fan attached to the heat sink
- Exhausts hot air out of the back of the case
Which of the following accurately describes case fans? (Select TWO)
Create a pressurized system inside the case
Pull cool air from the front and blow hot air out the back
Which of the following will ensure optimal system cooling? (Select THREE)
Bundle cables together and secure unused cables to the case
Leave space between the case and any walls or obstructions
Keep the ambient temperature below 80F
Which of the following characteristics accurately describe passive heat sinks?
More reliable than active heat sinks
Explanation: Passive heat sinks do not have a fan and instead rely on increased surface area and passive air movement to cool the component. Because they do not use a fan, passive heat sinks are 100% reliable. Passive heat sinks are used with most motherboard chipsets, low-end video cards, and memory modules.
You have just finished upgrading the CPU in your desktop system. After running the system for about 10 minutes, the system locks up and automatically restarts
Which of the following is the BEST first step in troubleshooting the problem? (Select TWO)
Check the CPU fan power
Make sure the heat sink is properly mounted and has thermal paste
Where should the thermal paste go when installing a processor?
Between the heat sink and CPU
A computer was brought into your help desk center for repair. You have been told that it randomly locks up.
Which of the following is MOST likely causing this issue?
Explanation: Overheated processor is the most likely cause of random system lockups.
