Cooling and Power Flashcards
Cooling the System
Thermal Load
Heat from different components inside the computer
Cooling the System
Passive Cooling
Type of cooling that doesn’t rely on moving parts or power
Cooling the System
Heat Sink
Finned metal device that radiates heat away from the processor
Cooling the System
Thermal Paste
▪ Compound that ensures heat transfer by eliminating air gaps
● Passive cooling requires no power to operate and is silent when
operating
Cooling the System
Active Cooling
Uses a fan to cool down the heat from the device
Liquid Cooling
Closed Loop System
Cooling of a single component
Liquid Cooling
Open Loop System
▪ Liquid cooling-based system of different components
Liquid Cooling
High performance systems
Alternating current (AC)
Cycled between positives and negatives repeatedly
The main purpose of power supply is to..
deliver DC to all components inside the
PC when receiving an AC power supply
Modular PSU / Modular Power Supply Unit
Allows to unhook the connectors and detach from the unit
▪ Modular power supply frees up space inside of the computer
Main Board / Motherboard Adapter
Provides power to the motherboard
ATX Standard
o 20-pin connector
ATX 12V
24-pin connector
20+4 Pin
Two connectors are coupled together before plugging into
a 24-pin connector
Processor Power/ CPU Power
▪ Has a four, six, or eight-pin connector
Molex Connector
▪ Used for IDE and PATA hard disks, CDs, and DVD drives
Y Connector
▪ One connector that can support multiple devices
US-based power supply
120V AC (Low Line Power)
▪ Europe and Asia power supply
230V AC (High Line Power)
Most power supplies will support ..
multi-voltage outputs
Voltage Sensing / Dual Voltage Power Supplies
Detects the outlet and converts it into the voltage of DC
Rail
▪ Wire that provides current at a particular voltage
● 12 VDC Rail
o Cable or wire that provides 12 VDC
o The 12 VDC rail is the most used voltage in the PC
