Would a i712700k(LGA1700) work for this socket
A 12th-gen CPU uses a different socket (LGA1700), so it physically won’t fit in an LGA1151 motherboard.
A 12th-gen CPU wouldn’t work in an LGA1151 motherboard because it requires more RAM slots than LGA1151 boards provide.
What is "Computer Hardware?"
Always wear a hard hat when using the computer.

Why is thermal paste important for CPU cooling
Thermal paste is important because it protects the CPU from physical damage if the cooler falls on it.
Thermal paste is important because it makes the CPU run faster by overclocking it automatically.
Thermal paste is important because it powers the CPU by providing electricity.
Thermal paste is important because it fills microscopic gaps between the CPU and cooler, improving heat transfer and preventing overheating.
What would happen if no thermal paste was applied to the CPU?
If no thermal paste is applied, the CPU will generate less heat than with paste.
If no thermal paste is applied, the CPU will still function normally without any risk of damage.
If no thermal paste is applied, the CPU can overheat because heat won’t transfer efficiently to the cooler.
If no thermal paste is applied, the CPU will automatically run cooler than normal.

Why shouldn't you mix ram
Mixing RAM forces the CPU to disable multiple cores to keep the system stable.
Mixing RAM will permanently damage the motherboard’s memory slots over time.
Mixing RAM, even if it’s the same brand and speed, can cause instability because the sticks may use different chips and timings that don’t always work well together.
Mixing RAM makes the graphics card run at a lower clock speed automatically.
When mixing ram:
Mixing RAM speeds makes the faster stick stop working completely
When different RAM speeds are mixed, the motherboard runs all sticks at the speed of the slowest one.
Mixing RAM speeds forces the computer to cut the total RAM in half.
Mixing RAM speeds automatically increases CPU temperature because it has to “balance” the memory.
Which one is true when it comes to mixing ram
Mixing RAM from different generations only reduces performance slightly but does not affect compatibility.
You can mix RAM generations as long as the speeds are similar and the motherboard BIOS is updated.
Mixing different RAM generations will still work, but the system will automatically convert the faster RAM to match the older type.
Mix RAM from different generations such as DDR4 and DDR3

Pick the ATX Motherboard
What Motherboard can NOT be used in this m-ATX case
Why might a motherboard support a CPU physically but still not be able to boot?
The CPU won’t boot because the motherboard automatically disables new CPUs unless all fans are running at maximum speed.
The CPU won’t boot because it can only run when the power supply is exactly 650 W.
The motherboard might need a BIOS update to support the CPU even if the CPU fits in the socket.
The CPU will not boot because it requires liquid cooling to start properly.
Why do some motherboards have Wi-Fi and others don’t?

Why are bottlenecks important?
Bottlenecks are only a concern in computers that use solid-state drives.
Bottlenecks automatically increase the speed of slower components to match faster ones.
Bottlenecks are dangerous and can physically damage your CPU or GPU.
Bottlenecks are important because they limit the performance of a system by slowing down the fastest components.
Why are the CPU and GPU most prone to bottlenecking each other?
The CPU and GPU bottleneck each other because they use the same cooling system.
The CPU and GPU bottleneck each other because they draw too much power from the motherboard.
The CPU and GPU are most prone to bottlenecking each other because they handle the majority of processing, so if one is slower, it limits the performance of the other.
The CPU and GPU bottleneck each other only if they are from different manufacturers.
