Do you Need an Aftermarket Cooler if you are Not Overclocking?

A lot of people contemplate whether or not to buy an aftermarket cooler if they don’t plan on overclocking their CPU especially when they are buying low to mid-range CPUs as most of those CPUs come with a cooler. If your CPU doesn’t come with a cooler, then you have no other option than to buy an aftermarket cooler.

it depends on the type of CPU. If you are using a high-end CPU like the i7, i9, or Ryzen 7 and Ryzen 9, you will need an aftermarket cooler because these CPUs don’t come with a cooler in the box. But if are using low to midrange CPUs like the non-K i5, Ryzen 3, and 5, then you don’t have to buy an aftermarket cooler if you don’t plan on overclocking because these CPU comes with a CPU cooler in the box.

Overclocking is when you change your CPU default speed to run at a higher speed instead. These changes make the CPU produce more heat and require more power than the default setting.

The box cooler will not be able to cool the CPU again because the CPU will produce more heat which the box cooler cannot dissipate. That is why you need an aftermarket cooler if you plan to overclock the CPU as most of these aftermarket coolers can dissipate heat from higher TDP-rated CPUs.

Overclocking makes a CPU heat to the extent that, if you don’t have a good cooling solution, your CPU will overheat and maybe get damaged.

You must also have a PC case with good ventilation and more case fans if you plan on overclocking your CPU. When the aftermarket cooler dissipates the heat from the CPU, that heat stays and circulates inside the case, so this is where a case with vents and case fans comes in.

Some of these case fans push the warm air circulating inside the case whiles other fans pull in fresh air to replace the warm air to keep the PC components cool all the time.

Also, make sure your case fans are placed well and have intake and exhaust fans. The front or bottom of the case is mostly where the intake fans are placed whiles the exhaust fans are placed at the rear or top of the case.

How do i know if i need an aftermarket CPU cooler?

Knowing whether or not your CPU needs an aftermarket cooler is very important and also helps extend your CPU life’s span. Below is how to know you need an aftermarket cooler.

  1. The most obvious way to know if your CPU needs an aftermarket cooler is if there is no cooler included with the CPU you bought.

  2. Even you there is a cooler included in the CPU and you notice your CPU temps are too high, like around 80 degrees, then you will need an aftermarket cooler.

  3. If you plan to overclock your CPU, you must use an aftermarket cooler because the box cooler will not be able to dissipate the heat anymore.

  4. If you want a noise-free system, then an aftermarket cooler is the way to silence your PC.

  5. If you want your PC to look nice with all those RGBs, aftermarket coolers like AIO will make your PC aesthetically pleasing.


You don’t need an aftermarket cooler if you are not overclocking your CPU, however, aftermarket coolers reduce your CPU temperature a lot. I am talking about 10 to 30 degrees off. If you are not on a tight budget, throw in around 35usd to get yourself a good aftermarket cooler.
