Factors To Consider When Buying The Best CPU Cooler For i9 9900k
We have developed a checklist of necessary factors to know while buying a CPU Cooler for i9 9900k. After all, it is always better to apprehend what you should foresee from your PC Cooler.
So, let’s take a quick look at our checklist:
Air Cooling vs. Liquid Cooling
There are two types of cooling systems integrated into a CPU Cooler, i.e., air cooling and liquid cooling.
Choosing between these two is a crucial decision to make. You have to prefer whether you want to cool your CPU by employing air or by utilizing a liquid loop. So, we have mentioned the pros and cons of both, decide for yourself.
Pros & Cons of Air Cooling
An air cooling system is a reliable option. This is the standard type of cooling system utilized for computers. One of the most significant benefits of air cooling is that it is cost-efficient and easy to install on your computer. Yet, it takes up a lot of space, and it could be a little loud. Concluding, if you need high-powered performance, air cooling is not ideal for your PC.
Pros & Cons of Liquid Cooling
In liquid cooling, a liquid circulates through the water blocks that rely on the top of the chip. Between the CPU and water blocks, there is a thermal paste and a baseplate. The purpose of keeping these between is to enhance the heat transfer properties.
As compared to air cooling, liquid cooling gives a quiet operation. It has a better heat regulation mechanism rather than air cooling. The visual looks of liquid cooling are cool enough due to the RGB elements.
But, liquid cooling is expensive; it isn’t easy to install liquid cooling, it takes a lot of time. There are a variety of problems associated with the maintenance of liquid cooling.
Correct CPU Socket
Most CPU coolers come with attachments that are suitable for motherboards.
Some CPU Cooler models need specific sockets. So when buying a CPU cooler, remember to check if it has standard CPU Sockets or not.
Dimensions and Clearance
When it comes to CPU coolers, there are various fans; each one has a different dimension.
Several CPU coolers have a low-profile design, and this means they will not block your RAM slots. Neither will they stay close to your PC casing wall.
Have you ever heard of dual-tower fans? Indeed, they have a high working yield, but they are way too bulky. So the thing is, make sure to take accurate measurements of clearance space.
Which fan to choose? PWM, DC, or Molex?
There are three main types of fan functionality. Let’s dig deeper into the details.
PWM Fans
So PWM means pulse width modulation. With this type of fan, you can change the RPM to keep the running volume down.
DC Fans
The next one ahead is DC fans, which are a subunit of PWM fans. You can slow them down to 40% below their average RPM.
Molex Fans
Molex fans don’t allow their consumers to do personal customizations. You can install Molex fans; they can run at total capacity, or else they are stationary. Molex fans are not the quiet ones, but they are affordable, a plus point if you are on a budget.
Noise Control
Most of CPU coolers are set on a mission to create an irritating sound when everything is calm around you.
To avoid irritating noise, remember to choose a CPU cooler that creates less noise.
More Tips
- If you are on a budget but need a practical solution, go for an air cooler.
- Air coolers are very common when it comes to CPU Cooling. Remember one thing, and more fans mean more cooling and more noise.
- Customize your RGB fan and sync your RGB peripherals to give it a feel. Also, regulate the RGB settings by adjusting the model.
Frequently Asked Questions
Does the i9-9900k need liquid cooling?
