Some older CPUs have pins instead of metallic connectors.
The CPUattaches directly to a CPU “socket”(or sometimes a “slot”) on themotherboard.
The CPU is inserted into the socket pin-side-down, and a small lever helps to secure the processor.

After running even a short while, modern CPUs can get very hot.
Typically, these come bundled with a CPU purchase.
Other more advanced cooling options are also available, including water cooling kits and phase change units.
Take great care when handling, especially when you’re installing them onto the motherboard.
CPU permitting, some applications can use what’s calledmultithreading.
Why one performs better or worse than others is a bit more complex but still pretty easy to understand.
Intel Core i3 processors are dual-core processors, while i5 and i7 chips are quad-core.
Intel Core i3 chips don’t have this capability.
Hyper-Threading enables the two threads to be processed per each CPU core.
This means i3 processors with Hyper-Threading support just four simultaneous threads (since they’re dual-core processors).
Another component of a CPU iscache.
CPU cache is like a temporary holding place for commonly used data.
Mac users should download System Monitor to monitor CPU temperature, processing load, and more.
Use an isopropyl wipe to gently wipe the thermal paste off your LGA socket.
Be sure to wipe in a straight line.
Repeat the process as necessary, using a fresh wipe with each effort.
To lowerCPU usage, free up space by disabling processes you don’t need via the Task Manager.
