Are All CPU Coolers The Same?

All CPU coolers are not the same, just as all computer processors are not the same either. They differ in many dimensions and offer different kinds of functioning. We have discussed some of the major differences in CPU coolers here. 

Size

The CPU coolers do not necessarily have the same size, even if they have the same socket for mounting. The size of a CPU cooler affects its ease of use and the way of mounting it too. So, you need to see which CPU cooler size will be better for you.

RGB Lights

The presence and absence of RGB lights also make a difference. They can alter the aesthetics of a CPU cooler with a long shot. The mystic RGB also increases the attractiveness of a CPU cooler. 

Construction Material

The construction of all the CPU coolers is different too. Some of them have simple plastic body while others have an aluminum construction. Plastic ones may be lightweight, but the aluminum ones have greater durability. 

Warranty

CPU coolers also differ in terms of the warranty that they come with. Those which offer greater warranty are naturally more reliable. They win the trust of the buyers easily and are more worthy of investing money in. 

How to Choose a CPU Cooler for i7 9700k

Choosing the right CPU cooler is necessary for enjoying a greater speed of your i7 9700k. This is why we have written down the aspects that you have to consider while making a purchase. 

Noise Production

Noise production of a CPU cooler is important to consider as it affects the ease of use. If a CPU cooler is noisier, then it will disturb you. But if its noise production is under 30 decibels, then it will help you concentrate better.

Number of Fans
