Lesson 5 Chapter 2 - Installing and Troubleshooting CPUs Flashcards
What are 3 steps to successfully installing a CPU?
- Make sure that it’s compatible with the motherboard
- Practice proper ESD avoidance
- Install a cooling solution (usually heat sink and fan assembly)
T or F: Motherboards support both Intel and AMD CPUs
False
What are the initial 3 steps when replacing/installing a CPU?
shut, area, space
- Shut down the pc and disconnect the power cable
- Place PC on an antistatic mat
- Make sure workspace is well light, enough room, and remove the case
What is symmetric multiprocessing?
body, multi
Symmetric multiprocessing is when a motherboard accept multiple physical CPUs
What are the next 4 steps to installing a CPU on an uninstalled motherboard? (If replacing a CPU, go to steps to remove heat sink and fan assembly)
lift, locate, ZIF
- Lift the CPU release lever arm and retention bracket (if necessary) on the ZIF socket
- Locate the orientation marker on the corner of the CPU and socket (corners with missing pins should align)
- Hold CPU by edges, position over the socket and gently set into place (without any force)
- Lower and lock the release lever into place
What are CPUs made of? (2)
High tech
1. Thermal plastics
2. ceramics
What is a heat sink?
A heat sink of made up of either aluminum or copper tine that wicks heat away from the CPU
What are heat sinks made out of? (2)
foil, penny
- aluminum
- copper
What is passive cooling?
get by
Passive cooling is when a CPU gets by on just being cooled by a heat sink itself, no fan
What devices have passive cooling?
Smartphones, tablets, other small communication devices
What is active cooling?
groupie
Active cooling combines both a heat sink and fan assembly to cool down a CPU
What can thermal paste be made out of? (3)
Need for speed, apple foil, werewolf
- Carbon
- Nano aluminum
- Polysynthetic Metal
Where does thermal paste go?
It is applied as a thin layer on the CPU, heat sink is placed on top
What are 3 other terms for thermal paste?
pill, autoshop, underworld
- Thermal compound
- Thermal grease
- That nasty silver goo
Besides thermal paste, what else can be used?
period
Thermal pads (or thermal gap pads)
What are thermal pads and what are they made of? (2)
Thermal pads don’t need adhesion to stick onto a surface, they are made to fill the gaps in between the heat sink and the cooling fan
They’re made of aluminum and fiberglass (0.01-0.2 inches thick)
What’s the difference between the heat sink and fan assembly for Intel and AMD fans? (2)
mount
- Intel stock fans - push the mounting pins in until they click in place (easy when motherboard is outside the case, support motherboard with one hand while installing to prevent flexing)
- AMD stock fans use a mounting bracket not push pins. Place heat sink, pull the lever to lock it in.
What is thermal throttling?
reduce
Thermal throttling is when the CPU reduces its performance in order to prevent overheating (and damage)
What does liquid cooling prevent? (2)
hit, reduce
- Prevents overheating/damage
- Prevents performance reduction
How does liquid cooling work? (3)
roundabout, kirby,transfer
- Cool liquid flows through the heat sink attached to the CPU
- Hot liquid is sent to the radiator
- Radiator sends hot liquid to outside the case to cool down (repeat)
What are 2 types of liquid cooling systems popular for PCs?
my hero academia, hoop
- All-in-One liquid cooling systems
- Custom loop coolers
How do AIO cooling systems work?
cheese, workout, pool, groupie
AIO systems contain a block with a pump attached to the CPU, 2 tubes are connected to a radiator with fans to cool down the liquid
What are 5 general steps (vary) in replacing a CPU in a laptop?
re, re, re, re, re
- Remove power sources and battery (consult the manufacturer for built-in batteries)
- Remove screws, panels to access CPU
- Remove heat sink and fan assembly, lift out CPU
- Replace with another CPU, apply thermal paste, reattach heat sink and fan
- Reconnect the fan power connector and reassemble the laptop
How do you remove a CPU that has passive cooling and the CPU is pointed up not down?
re and re, nekked
May need to remove the keyboard, then remove the heat sink and fan assembly to access the CPU underneath
What does the CMOS clear setting do? For what component is it for?
re
The CMOS clear setting on the motherboard resets the BIOS/UEFI utility settings to the default
What are two reasons why someone would underclock their device?
less, slowly
- Reduced performance means reduced heat to prevent overheating and can get by with passive cooling with less fan noise
- Reduced power consumption
___ rarely have problems after they’re installed
CPU
What are 4 signs of CPU installation problems and how to solve them?
no fan, fan on, hot, dead/dead
- Fan is not running, or doesn’t run for more than 5 seconds
- Fan is spinning but PC doesn’t boot, check jumpers are correct for speed and voltage
- CPU overheating hear alarm, check fan installation and CPU/heat sink contact
- System won’t power on, fan won’t spin. CPU is seated properly? Components were unseated during installation?
What are 4 signs of cooling issues?
re, fire, key, jordin
- Spontaneous reboots
- Occasional alarms from the tiny PC speaker
- Lockups
- Excessively loud fans
You should attach the ___ to the heat sink before installing
fan
What are the 4 general steps to installing a heat sink?
re or apply, mount, stock, fight the
- Remove protective tape of thermal paste if pre-applied, or apply a thin film of thermal paste to the raised center of CPU package
- Align mounting bracket hardware on heat sink/fan with the mounting notches on the CPU socket
- Intel stock fans use the push pins until it clicks, AMD fans use mounting bracket and pull lever to lock in place
- Plug the fan’s power cable into the appropriate socket/header on motherboard
