Cooling Systems Flashcards
What does the inside of a computer always need regarding cooling?
Good airflow and cooling to a good temperature of hardware. There needs to be air and cooling in a holistic way, as well as to the CPU and motherboard individually.
What is a heat sink?
Anything that can take heat from another device.
CPU heat sinks sit on top of the CPU itself and transfer heat away from it - there are copper tubes that transfer heat to the sink, then the fan or fins will dissipate the heat out into the outside air.
What problem can cause the computer to suddenly reboot a lot?
Overheating.
Make sure there’s airflow within the machine.
What parts of the computer are most likely to cause the most heat?
CPU, motherboard, video cards, hard drive.
What is the quietest solution for cooling your computer, but also is the most expensive?
Liquid cooling.
What are the options of cooling a system?
- Fans
- Liquid cooling
- Heat sinks
- Basic air movement inside the case
- Fins (fanless passive cooling)
- Heat pipes
- Peltier cooling devices
- Phase-Change Cooling
- Liquid nitrogen and Helium Cooling
- Undervolting
What does noise of a fan depend on?
Size and speed of the fan.
For example, small fans are louder because they have to move faster to move the same amount of air as a larger one.
thermal paste and thermal pads
conduct heat and are used between the component and heat sink to make the best thermal-conductive connection.
liquid cooling
more effective at transferring heat away from components. Distilled water is the most commonly used liquid. Liquid cooling systems include a tank for the liquid, a radiator, a water pump, and a cooling block that attaches to the component being cooled. These components may be in the computer or outside in a separate unit that connects to the computer.
Most expensive, most effective
